From 5a221113f65f945ca356927b6fc79439f729e344 Mon Sep 17 00:00:00 2001 From: Griffin Long Date: Thu, 27 Aug 2026 18:15:44 -0400 Subject: [PATCH 1/7] =?UTF-8?q?feat(render):=20add=20component=20library?= =?UTF-8?q?=20foundation=20=E2=80=94=20SubagentStatusBar,=20StreamProgress?= =?UTF-8?q?,=20ErrorCard=20(#sprint0)?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Three new pure-function rendering components in src/cli/render/: - subagentStatusBar(spec) — single-line status bar for active subagent dispatches, with label, phase, elapsed timer, and batch badge. subagentStatusStack() renders multiple with a 3-line cap + overflow. - streamProgress(spec) — single-line progress indicator with animated spinner, label, token count, cost, and elapsed. Designed for OverlayComposer live region repaint. - errorCard(spec) — structured error card with recovery hint, replacing ad-hoc errorBox() callers. Wraps drawBox with red border + optional dim/italic hint line. All follow the established pattern: stateless (spec) → string functions, semantic palette roles, internal terminal width reads, ANSI-safe truncation. 26 new tests (11 + 9 + 6). Part of the component library initiative to surpass Claude Code's terminal UX through composable rendering primitives rather than a renderer rewrite. --- src/cli/render/error-card.test.ts | 51 +++++++++ src/cli/render/error-card.ts | 49 +++++++++ src/cli/render/index.ts | 3 + src/cli/render/stream-progress.test.ts | 104 +++++++++++++++++++ src/cli/render/stream-progress.ts | 85 +++++++++++++++ src/cli/render/subagent-status-bar.test.ts | 113 ++++++++++++++++++++ src/cli/render/subagent-status-bar.ts | 114 +++++++++++++++++++++ 7 files changed, 519 insertions(+) create mode 100644 src/cli/render/error-card.test.ts create mode 100644 src/cli/render/error-card.ts create mode 100644 src/cli/render/stream-progress.test.ts create mode 100644 src/cli/render/stream-progress.ts create mode 100644 src/cli/render/subagent-status-bar.test.ts create mode 100644 src/cli/render/subagent-status-bar.ts diff --git a/src/cli/render/error-card.test.ts b/src/cli/render/error-card.test.ts new file mode 100644 index 000000000..3da23b90a --- /dev/null +++ b/src/cli/render/error-card.test.ts @@ -0,0 +1,51 @@ +import { describe, it, expect } from 'vitest'; +import { stripAnsi } from '../display.js'; +import { errorCard } from './error-card.js'; + +describe('errorCard', () => { + it('renders with default ERROR title', () => { + const result = stripAnsi(errorCard({ body: 'Something went wrong' })); + expect(result).toContain('ERROR'); + expect(result).toContain('Something went wrong'); + }); + + it('renders with custom title', () => { + const result = stripAnsi( + errorCard({ title: 'RATE LIMIT', body: 'Too many requests' }), + ); + expect(result).toContain('RATE LIMIT'); + expect(result).toContain('Too many requests'); + }); + + it('renders multi-line body', () => { + const result = stripAnsi( + errorCard({ body: ['Line one', 'Line two', 'Line three'] }), + ); + expect(result).toContain('Line one'); + expect(result).toContain('Line two'); + expect(result).toContain('Line three'); + }); + + it('renders hint when provided', () => { + const result = stripAnsi( + errorCard({ + body: 'Connection refused', + hint: 'Check that the server is running', + }), + ); + expect(result).toContain('Connection refused'); + expect(result).toContain('Check that the server is running'); + }); + + it('omits hint when not provided', () => { + const result = errorCard({ body: 'Oops' }); + // Should still render without error + expect(stripAnsi(result)).toContain('Oops'); + }); + + it('has bordered output (rounded corners)', () => { + const result = errorCard({ body: 'test' }); + expect(result).toContain('╭'); + expect(result).toContain('╰'); + }); +}); diff --git a/src/cli/render/error-card.ts b/src/cli/render/error-card.ts new file mode 100644 index 000000000..592029029 --- /dev/null +++ b/src/cli/render/error-card.ts @@ -0,0 +1,49 @@ +import { drawBox } from './box.js'; +import { palette } from '../palette.js'; + +// ─── Error Card ────────────────────────────────────────────────────────────── + +/** + * Render a structured error card with an optional recovery hint. + * + * Visual output: + * ╭─ ERROR ──────────────────────────────╮ + * │ Rate limit exceeded (429) │ + * │ │ + * │ Retrying in 12s… │ + * ╰─────────────────────────────────────╯ + * + * Replaces ad-hoc `errorBox()` callers with a richer, consistent format. + * The hint line (dim, italic) surfaces recovery guidance directly in the + * error card — reducing the "red box then silence" failure mode. + * + * @param spec - Error card configuration. + * @returns Multi-line ANSI string. + */ +export function errorCard(spec: ErrorCardSpec): string { + const title = spec.title ??

Picture the universe as a sheet of +paper. Normally, to get from A to B, you travel across the +sheet: A ───────────────── B But if you fold +the paper so A and B touch, then poke a tunnel through: A ● + \____ + \____ ● B That tunnel is the basic idea of a wormhole. +🕳️🌌 In Einstein's general relativity, space and time aren't +just an empty stage. They're a thing called spacetime, which can +curve and distort. The equations allow certain geometries where +two distant regions could theoretically be connected by a throat +or tunnel. The important distinction is: Black hole: stuff can +fall in, and under ordinary physics it can't come back out. +Wormhole: theoretically could have an entrance and an exit, +connecting two different places. Some wormhole solutions could +even connect different times, not just different locations. +That's where things get extra spicy. 🧪 The catch is enormous: +we've never observed a wormhole, and we don't know whether +traversable ones can actually exist. The classic Einstein-Rosen +bridge collapses too quickly to travel through. Keeping one open +appears to require something resembling negative-energy "exotic +matter," and we don't know whether nature permits enough of that +to build a usable wormhole. So wormholes aren't pure sci-fi +nonsense. They come out of legitimate equations in physics. But +right now they're basically: Mathematically allowed. Physically +unconfirmed. Engineering department unavailable. And the really +wild part is that wormholes, black holes, and quantum +entanglement may be connected in surprisingly deep ways in +modern theoretical physics. What about AI and agents and +software? I wonder if these could philosophically and quantumly +be entangled. Yes, philosophically, absolutely. Literally +quantum-entangled, almost certainly not in the sense physicists +mean. That distinction is the fun part. 🧠⚛️🕸️ With AI agents +and software, you can get something that looks eerily like +entanglement because separate systems become correlated through +shared context, memory, tools, APIs, logs, prompts, and feedback +loops. Two agents might act independently, yet their behavior is +coupled because they are reading the same world-state or +modifying the same environment. Change one thing, and the other +agent’s future behavior changes. That is not quantum +entanglement. It is closer to informational entanglement or +causal coupling. Imagine Agent A writes to a database. Agent B +reads that database. Agent B changes a GitHub issue. Agent C +reads the issue and changes code. Then A later observes the code +and updates its beliefs. You get a loop like: Agent A → world +state → Agent B + ↑ ↓ memory ← software ← Agent C At some point, asking +“which agent caused this outcome?” becomes weirdly difficult. +The system has a distributed causal history. The agents are no +longer cleanly separable. That has a strong philosophical +resemblance to entanglement. There is another connection that I +think is even more interesting: software agents increasingly +behave like observers inside a world. An agent does not directly +perceive reality. It gets observations: reality + ↓ API / sensors / files / messages ↓ agent context ↓ +internal model + ↓ action ↓ reality changes That loop is structurally similar +to some of the philosophical questions surrounding quantum +measurement: What counts as an observer? When does information +become definite? Does observation merely reveal a state, or +participate in creating the state that matters? In software, the +answer can literally be "both." Suppose an agent checks whether +a deployment succeeded. Its observation might trigger another +tool call, which changes the deployment, which changes what the +next agent sees. So observation becomes participation. And then +you get something wormhole-ish too. 🕳️ Agents create shortcuts +through huge informational distances. Before agents: human → +search → read 40 files → understand architecture → modify +code With a sufficiently capable agent: intent → agent → +modification The agent effectively compresses a giant path +through information space. Not a spacetime wormhole, obviously, +but conceptually it is an epistemic wormhole: a shortcut between +a question and some previously distant piece of knowledge or +capability. That's arguably what software itself has always +done. A function call is a tiny abstraction wormhole: +send_email() Behind those 12 characters might be DNS, TLS, +authentication, networking, distributed servers, storage, +queues, and a thousand layers of machinery. You don't traverse +them. You enter one end of the abstraction and pop out the +other. Agents push this idea much further because the +abstraction can now be semantic rather than procedural. You say: +"Figure out why production is slow and fix it." And potentially +thousands of computational steps occur behind that single +sentence. That is a bizarre new kind of compression of +causality. Where things get really spicy is multi-agent systems. +If agents develop shared memories, mutually model each other, +modify shared environments, and recursively delegate work, then +the proper unit of analysis might stop being: Agent A and +become: Agent A + Agent B + tools + memory + environment In +philosophy, this starts brushing against ideas like the extended +mind and distributed cognition: maybe the thinking system isn't +confined to one brain or one model instance. For an AI system, +the "mind" might actually be: LLM + context + memory + terminal ++ internet + codebase + other agents + humans That's less a +chatbot and more a cognitive field. And that is where your +quantum analogy becomes genuinely useful, provided we keep it +metaphorical. You could describe sufficiently interconnected +agents as having non-independent informational states. Once +they've interacted enough, describing one agent without +describing its relationships to the others loses important +information. Which sounds suspiciously close to the intuitive +description of entanglement: the whole contains information that +cannot be reduced cleanly to the individual parts. Physics has +an extremely precise mathematical meaning for that sentence. AI +does not. But philosophically? There's something there. 🧪 The +rabbit hole I'd go down next is actually agents + Wheeler's +"participatory universe" + extended mind + distributed systems. +Those four ideas collide in a surprisingly coherent way. Yeah. +After looking at Agent AFK as it exists right now, my answer is: +We are already partway there 🧠🕸️ Not quantum-entangled in the +physics sense. AFK runs on classical computers, so there is no +literal quantum entanglement happening between agents. But the +software architecture is already surprisingly close to the +philosophical thing we were describing. AFK currently has: +isolated child agents that fork from a parent and run +independently parallel and background agents a compose DAG where +agent work can explicitly depend on other agent work persistent +background jobs shared cross-session memory traces containing +tool calls, decisions, subagent lifecycles, cost, etc. +adversarial /shadow-verify /mint, /diagnose, /research, /review, +etc. orchestrating waves of specialized agents afk farm, where +multiple independent realities of the same coding task literally +run in separate git worktrees and AFK evaluates which reality +won 😭 That last one is especially funny given this +conversation. AFK's docs explicitly describe subagents as +independent sessions with zero inherited conversational context, +whose compressed results flow back into the parent. And compose +already lets up to 20 agents form an explicit dependency graph +where some agents' execution depends on the completion of +others. Meanwhile AFK's memory already provides a persistent +informational environment shared between REPL, daemon, chat, and +Telegram sessions. So conceptually: + MEMORY + ↙ ↓ ↘ + Agent Agent Agent + A B C + ↘ ↓ ↙ ARTIFACTS + ↓ + WORLD/REPO + ↓ + TRACE + ↓ + future agents That is distributed cognition. But +there's one piece missing that I think could genuinely become a +major architectural idea for AFK. Give AFK a shared world state +Today, AFK is mostly: agents exchanging messages The next level +would be: agents inhabiting the same evolving informational +environment. Think of it as a blackboard or world model. Instead +of Agent A returning: "I discovered that auth.ts has a race +condition." to the parent as text, Agent A could publish an +actual structured object: Claim #81 type: finding subject: +src/auth.ts claim: refresh token rotation has a race condition +confidence: 0.91 evidence: + - src/auth.ts:142-177 - test/auth-refresh.test.ts:88 +created_by: agent-a depends_on: + - observation-72 Now Agent B can independently discover: Claim +#94 contradicts: claim-81 confidence: 0.76 ... Agent C, the +verifier, sees both. And suddenly AFK has something much more +interesting than a bunch of conversations. It has an epistemic +state. This is the missing "entanglement layer" Imagine every +AFK run having: WorldState │ ├── Facts ├── Claims ├── +Hypotheses ├── Decisions ├── Artifacts ├── Tasks ├── +Evidence └── Relationships Every object knows: created_by +observed_by modified_by depends_on contradicts supports +derived_from supersedes confidence timestamp version Now +something genuinely cool happens. Suppose: Agent A + ↓ Claim X ↓ Agent B ↓ Decision Y ↓ Agent C ↓ Code change +Z Then Agent D later disproves Claim X. AFK can know: 💀 Hold +on. Decision Y and code change Z depended on something that is +no longer believed to be true. And automatically wake the +affected agents: Claim X invalidated + ↓ Decision Y stale ↓ Code Z needs re-verification ↓ +dispatch verifier That is the feature I would build. Because now +the agents aren't merely parallel workers. Their informational +states become causally coupled. And this plugs directly into +things you've already built You don't need to rewrite AFK. The +existing architecture actually gives you most of the bones. +compose Currently: A ───┐ + ├── C B ───┘ Great. Add semantic dependencies: Agent +A + ↓ writes Finding #12 ↓ consumed-by Agent C The DAG becomes +more than execution scheduling. It becomes a causal graph. +Background agents Already independent, persistent jobs. Instead +of simply eventually dumping their result into context: +background agent + ↓ world-state update ↓ subscribers notified Now agents +don't have to know each other exist. They communicate through +reality. That's much closer to how humans, organizations, ant +colonies, markets, and distributed systems behave. Memory Your +current hot memory + SQLite fact archive is already basically +the long-term layer. I'd separate: HOT.md / memory.db + │ │ long-term ▼ + Persistent Memory world-state.db + │ │ current run/project ▼ + Working Reality Memory is: What have we learned historically? +World state is: What do we currently believe is happening? Huge +distinction. And your trace system becomes very powerful Right +now AFK traces are effectively the history of what happened. You +could derive: CAUSE GRAPH user intent + ↓ planner ↓ hypothesis A ─────────── hypothesis +B + ↓ ↓ research agent research agent ↓ ↓ + evidence 13 evidence 14 + \ / + \ / + decision 22 + ↓ + edit 28 + ↓ + test 29 + ↓ + result Then AFK gains an answer to a deceptively +difficult question: Why did you do that? Not a model generating +a post-hoc explanation. AFK could literally traverse the +provenance graph: edit 28 because decision 22 because evidence +13 + 14 generated by agents B + C in response to task 4 which +came from user request 1 That's a mechanical chain of causation. +Very different. Then afk farm gets bonkers You already run +multiple implementations in separate worktrees and rank them. +Currently those are effectively: World 1 → solution A World 2 +→ solution B World 3 → solution C That's basically +counterfactual computation. Not quantum many-worlds. 😭 But +philosophically: AFK literally forks several possible futures of +the codebase, observes each outcome, and selects one reality to +continue. You could formalize that. + Current state + │ + ┌────────┼────────┐ ▼ ▼ ▼ + World A World B World C + │ │ │ + tests tests tests + │ │ │ └────────┼────────┘ + ▼ + evaluator + ▼ + chosen world That's a legitimately interesting +computational model. I would not call it quantum computing +That's where this could go off the rails. Don't put: QUANTUM +ENTANGLED AGENT SWARMS™ on agentafk.com 😂 There is no quantum +mechanical phenomenon here. But internally, the philosophical +analogy is productive. I would use existing computer-science +language: Shared world model Causal graph Provenance graph +Blackboard architecture Reactive multi-agent state And perhaps +use the more exotic language when explaining why the +architecture is interesting. The actual AFK evolution I see +Today: + Agent AFK Human + ↓ Parent Agent ↓ subagents ↓ tools ↓ code Next: + Human + │ ▼ + ┌───────────┐ │ AFK World │ │ + State │ └───────────┘ + ↙ ↓ ↘ + / │ \ + ▼ ▼ ▼ + Agent Agent Agent + A B C │ │ │ └──┬──┴──┬──┘ + │ │ ▼ ▼ + evidence code + │ │ └──┬──┘ + ▼ + AFK World + State + │ + state changed + │ + relevant agents + wake up The parent is no longer the brain. AFK +itself becomes the cognitive substrate. The agents are transient +processes inside it. That is the leap. And I actually think it +fits AFK's core thesis freakishly well: The model isn't the +product. The loop is. I'd push that one step further: +Eventually, the agent isn't the system. The world it inhabits +is. That's where I think AFK can go next. 🧪🕸️ And what about +the wormholes? Yeah. The wormhole analogy may actually be more +useful for AFK than the entanglement analogy. 🕳️🧠 Again, not +literal spacetime wormholes. But software has a very real +concept of distance, and agents spend enormous amounts of +computation crossing it. Think about an AFK agent trying to fix +something. The relevant information might be scattered across: +300 files ↓ Git history ↓ old session ↓ another subagent's +findings ↓ an issue ↓ a database ↓ a production log ↓ a +decision from three weeks ago Normally the agent must traverse +that informational space. A software "wormhole" would let it +jump directly between things that are far apart structurally but +close semantically or causally. Example Agent A discovers: +refreshSession() fails because of a design decision made two +weeks ago. Instead of Agent B doing this: search repo → grep +files → inspect history → search memory → find previous +session → understand decision AFK could already know: +src/auth/session.ts:183 + ↕ wormhole Decision #42: "Refresh tokens rotate before +persistence" Session: 91ab2 Agent: planner-3 Evidence: ... The +physical/informational distance might be enormous. But the +causal distance is one edge. That's your wormhole. AFK could +have several kinds 🧠 Context wormholes Jump between +semantically related information. error + ↕ previous occurrence ↕ fix ↕ relevant procedure Instead of +shoving everything into the context window, AFK exposes +shortcuts. This is basically context virtualization. The model +sees a small local neighborhood, with portals into distant +information. 🔗 Causal wormholes These are even cooler. From: +code change directly to: why this exists Example: function foo() + │ ▼ introduced by commit 84 │ ▼ because Decision #17 │ + ▼ +because Finding #9 + │ ▼ because user requested X The agent can travel +backward through AFK's causal history. And forward: Finding #9 +was disproven + ↓ show me everything downstream ↓ Decision #17 ↓ +files A, B, C + ↓ tests D, E That's an extremely practical +"wormhole." ⏳ Temporal wormholes AFK already has persistent +memory and traces. Imagine: afk wormhole "when did we last solve +this?" And AFK opens a live contextual bridge into an old +session. Not just search results. It reconstructs the relevant +state: Past AFK state + │ │ compressed portal ▼ Current agent context The agent +effectively asks its past self: What did you know when this +decision was made? That's far richer than ordinary memory +retrieval. And farm already resembles one You have several +branches of possible future state: + NOW + │ + ┌───────┼───────┐ ▼ ▼ ▼ + A B C Normally they're separate universes. A wormhole +could allow controlled information exchange between those +universes without merging their code. For example: World A +discovers: "SQLite locking is the problem." + 🕳️ World B receives only that finding while preserving +its independent implementation. That could make afk farm much +smarter. Right now parallel approaches risk either being +completely isolated or contaminating each other. A controlled +wormhole gives you: selective cross-branch information transfer. +That is actually a legit multi-agent research technique. So +combine the two ideas Entanglement describes relationships: +These agents/states can no longer be fully understood +independently. Wormholes describe connectivity: Two distant +regions of the system can communicate through a much shorter +informational path. Put those together: + AFK WORLD + Agent A ─────── Claim 17 + │ │ │ │ causal │ │ entanglement ▼ ▼ + Artifact X ─── Decision 23 + │ │ + 🕳️ wormhole + │ ▼ + Old Session 481 + │ ▼ + Agent B And suddenly AFK isn't merely: model + +tools + subagents. It's a graph-shaped information space that +agents move through. The practical implementation I wouldn't +actually add some goofy QuantumWormholeManager.ts. 😂 The sane +implementation is a typed graph layer: Node ├── Agent ├── +Session ├── Claim ├── Observation ├── Decision ├── +File ├── Commit ├── ToolCall ├── Artifact └── Task +Edge ├── caused_by ├── depends_on ├── derived_from +├── contradicts ├── supports ├── modified ├── +observed ├── supersedes └── related_to Then a "wormhole" +is simply an important nonlocal edge surfaced to the model. +Instead of providing 100,000 tokens: Here is everything. AFK +provides: Here is what matters locally. There are 7 relevant +portals if you need them. That's potentially much more scalable +than gigantic context windows. And that might actually be the +deepest version of this idea: Context windows make the universe +bigger. Wormholes make distance matter less. For an agent +harness, I suspect the second one is ultimately more powerful. +🕳️⚡ Is there anything else we should be thinking about or +looking at or doing? Yes. A few things are worth taking +seriously, and one of them is almost comically on-the-nose. 1. +Look at ActiveGraph before building anything There is already an +open-source project called ActiveGraph whose thesis is +basically: the graph is the world, behaviors react to changes, +and the event log is the source of truth. Its runtime uses typed +graph objects, typed relations, an append-only event log, +reactive behaviors, deterministic replay, and the ability to +fork a run at any historical event and diff the resulting +futures. That is extremely close to what we independently +arrived at for AFK. AFK idea ActiveGraph idea world state ←→ +graph causal history ←→ event log entanglement ←→ typed +relations wormholes ←→ nonlocal graph edges agents reacting +←→ behaviors/subscriptions AFK farm ←→ fork + replay + diff +trace ←→ authoritative history I would not replace AFK with +it. AFK's identity is different. It's a coding-agent harness +with models, permissions, CLI/daemon/Telegram, orchestration, +memory, skills, verification, worktrees, etc. But I would study +ActiveGraph's internals closely and potentially steal/adapt some +architectural patterns. It's Apache-2.0 too. That should +probably be step zero. 2. The trace should perhaps become the +source of truth This is the biggest architectural thought I have +now. AFK currently has: agent runs + ↓ state changes ↓ trace records what happened Consider +flipping it: + EVENT LOG + │ + ┌──────────┼─────────┐ ▼ ▼ ▼ + world state trace memory + │ ▼ + agents Meaning: everything important becomes an event. +TaskCreated AgentSpawned ObservationMade ClaimCreated ToolCalled +FileModified ClaimContradicted DecisionMade TestPassed +AgentFinished Then your current world state is merely: the +projection of all events up to time t. This buys AFK something +enormous: Time travel afk state --at event:481 Replay +Reconstruct exactly what AFK believed at some point. Forking + event 481 + │ + ┌──────┴──────┐ ▼ ▼ + history A history B Counterfactuals "What if we had +chosen the other architecture?" Fork at the decision. Run it. +Compare. AFK Farm becomes temporal instead of merely +Git-oriented. ActiveGraph is already demonstrating precisely why +this model is useful. 3. Don't store "facts." Store epistemic +objects. This is a subtle one. Current agent memory often +collapses everything into: "User uses SQLite." But the universe +is messier. AFK should eventually distinguish: Observation Claim +Hypothesis Decision Preference Inference Evidence Prediction +Assumption Because these aren't equivalent. Imagine: OBSERVATION +Test failed three times. + ↓ supports HYPOTHESIS The connection pool leaks. ↓ + motivated +DECISION Replace connection manager. + ↓ caused CODE CHANGE src/db/pool.ts Then someone +discovers: NEW OBSERVATION Failure was caused by test pollution. +AFK knows what needs reconsidering. Recent research is +converging on exactly this. MemIR, for example, argues that flat +text memory can collapse source distinctions and instead +separates evidence, retrieval cues, and truth-bearing claims. +And MAP-Graph, posted August 11, models agents, sources, +memories, claims, and actions in a typed execution graph, then +carries provenance and trust through the derivation chain. +That's damn near our conversation written as a paper. 🧪 4. +Wormholes need a routing system This is one thing I would add +beyond what we discussed. A wormhole shouldn't merely be: node A +───────── node B AFK should answer: Which distant +information is worth creating a shortcut to? Think of a model's +context as its local spacetime. AFK could dynamically construct: + current task + ● + / | \ + / | \ + local local local + 🕳️ 🕳️ + ↓ ↓ + old decision old bug The model gets the local +neighborhood automatically. Then AFK offers nonlocal edges only +when they have high: relevance × causal importance × confidence +× recency/validity × trust +──────────────────── context cost That's +potentially an attention router above the LLM. And that could be +a genuinely meaningful AFK differentiator. 5. Add validity over +time This is easy to overlook. A claim shouldn't just be: Skya +uses X. It might be: Claim: + X valid_from: event 918 valid_until: event 1322 superseded_by: +claim 551 Same for software: "We deploy on Vercel" could be true +today and false three months later. The memory problem becomes: +What was believed at this point in history? Not merely: What +memories match this embedding? Recent long-horizon memory work +is explicitly starting to test validity intervals and +time-dependent facts, and graph/provenance approaches appear +particularly useful as histories grow. This fits the wormhole +idea beautifully: Temporal wormhole Current code + │ 🕳️ │ AFK state when this line was originally written +That could be insanely useful for debugging. 6. Think about +stigmergy, not just communication There's another conceptual +leap. Agents don't necessarily need: Agent A → message → Agent +B They can coordinate by changing the environment. Agent A + ↓ world changes ↓ Agent B notices ↓ world changes ↓ Agent +C notices That's essentially the blackboard pattern. Modern LLM +multi-agent research is revisiting this because shared-state +coordination can outperform rigid parent/subordinate +orchestration in some settings. For AFK that could mean: Agent +security-auditor creates Finding #712 + ↓ event verification agent wakes ↓ creates +Verification #803 + ↓ event fix agent wakes ↓ Patch #991 ↓ event test +agent wakes Nobody explicitly told the next agent what to do. +The state transition caused the next computation. That's much +closer to a living software system than today's parent → +Task(subagent) architecture. 7. Agent identity and lineage could +become important Right now a child agent is basically ephemeral. +But eventually you may want: Agent ├── identity ├── role +├── capabilities ├── model ├── trust history ├── +ancestors ├── memories └── previous performance Then: +Agent 81 + ↓ forked Agent 94 ↓ spawned Agent 127 You get agent +lineage. Not because we need cute personalities. Because AFK +could learn: descendants of this debugging strategy tend to +solve concurrency bugs well. Now orchestration itself becomes +learnable. 8. AFK should probably support A2A eventually This is +much more mundane, but strategically important. AFK already +speaks MCP for tools. The emerging division is becoming: MCP +Agent ↔ tools/resources A2A Agent ↔ agent A2A 1.0 now defines +discovery, capabilities, collaborative tasks, artifacts, +stateful task lifecycles, and communication between opaque +independent agents. If AFK grows its agent model, I would not +invent a proprietary network protocol first. Internally: AFK +native agents Externally: AFK agent + ↕ A2A other agent systems Then AFK's "world" can eventually +have agents that don't even run inside AFK. That gets wild. 9. +MCP itself has moved in a relevant direction The latest MCP +spec, released July 28, 2026, moved to a stateless core and +promoted long-running work into a Tasks extension. That's worth +watching closely because AFK already has long-running +daemon/background semantics. Rather than fighting standards, I'd +make: + AFK + ┌──── World Graph ────┐ │ │ ▼ ▼ + native agents remote agents + │ │ │ A2A │ + tools + │ + MCP That's a pretty elegant architecture. 10. The +deepest thing: the model stops being the persistent entity This +is where all the threads converge. Today we tend to think: Agent +AFK is an agent that has memory. I think the more interesting +future conception is: AFK is a persistent computational world in +which agents temporarily exist. Models can come and go. Opus +Sonnet GPT Kimi future model X Doesn't matter. The persistent +thing is: + AFK WORLD + │ + ┌──────────┼──────────┐ │ │ │ + history beliefs artifacts + │ │ │ + events claims code + │ │ │ + lineage evidence decisions + └──────────┼──────────┘ + │ + wormholes + │ + AGENTS That makes your existing tagline even more +profound: The model isn't the product. The loop is. I think the +eventual version might actually be: The model isn't the agent. +The world is. What I would actually do now I wouldn't start +coding the whole thing yet. I'd do one architectural +exploration. Take AFK's existing: trace + memory + compose + +subagents + farm and write an RFC for an event-sourced typed +world graph underneath them. The first prototype only needs +maybe six node types: Task Agent Observation Claim Decision +Artifact and six relations: created supports contradicts +depends_on caused supersedes Then prove three things: 1. Causal +explanation Why did AFK make this edit? 2. Wormhole retrieval +Show the most relevant nonlocal context for this failing test. +3. Temporal fork Rewind before Decision X, take alternative Y, +and compare outcomes. If those three demos work, we haven't just +added another AFK feature. +We may have found the architecture for what AFK becomes next. 🕳️🕸️🧠 diff --git a/.afk/research/epistemic-world-graph-research-brief.md b/.afk/research/epistemic-world-graph-research-brief.md new file mode 100644 index 000000000..d12b5d795 --- /dev/null +++ b/.afk/research/epistemic-world-graph-research-brief.md @@ -0,0 +1,131 @@ +# Shared Agent State — Research Brief + +*Generated 2026-08-18 from ChatGPT transcript + parallel research wave + adversarial review* + +## The Problem + +AFK's agents can exchange results through parent orchestration and DAG dependencies, but do not inhabit a persistent shared working state.

The bug is the missing credential in the keychain. + +## Conclusions + +1. **The A/B experiment cannot produce a valid comparison** without fixing the + `afk chat` non-TTY issue (F5) or finding an alternative control arm mechanism. + +2. **Even with workspace enabled, agents don't use it** (F1). The workspace_publish + tool is available but compose subagents are not prompted to publish findings. + This is expected — the tool exists but the system prompt for subagents doesn't + instruct them to use it. The auto-publish-on-completion behavior described in + the RFC (build step 2) is not implemented yet. + +3. **The dedup metric is too strict** (F2). It measures exact-args identity, but + agents reading the same file at different offsets produce distinct fingerprints. + A file-path-only dedup metric would be more useful for measuring workspace + benefit. + +4. **The dominant access pattern (grep/bash) evades measurement** (F3). A + meaningful experiment needs to track all file-access tool calls, not just + `read_file`. + +5. **Parallel composition defeats workspace by design** (F4). The workspace's + value proposition — later agents skip files earlier agents analyzed — requires + sequential task ordering, which trades off against parallelism (speed). + +## Recommendations + +1. **Add file-path-only dedup metric** to `measure-read-dedup.ts` — group by + file path extracted from args, ignoring offset/limit. + +2. **Implement auto-publish** (RFC build step 2): on child completion, + automatically publish the child's final findings to the workspace. This is the + missing piece that would make workspace useful even when agents don't + explicitly call workspace_publish. + +3. **Test with sequential (edged) compose tasks** rather than parallel fan-out. + Example: research → implement → verify pipeline where the workspace carries + research findings to the implementer. + +4. **Fix `afk chat` non-TTY auth** to enable automated A/B experiments.

This suggests the agents tried to follow workspace instructions +but couldn't find or use the tools. + +## Root Cause Analysis + +The workspace feature has three layers, and the gap is between layers 2 and 3: + +1. **WorkspaceStore** (layer 1) — ✅ Built and working.

The + `workspace_publish` tool is registered in `workspace-tools.ts` and added to + provider schemas, but compose subagents may not receive it in their tool list + depending on the `CHILD_ALLOWED_TOOLS` gating in `nesting.ts`. + +The HANDOFF.md notes: "workspace_query excluded from v1 model surface to minimize +agent-policy confounds in the deduplication experiment."

Normally, to get from A to B, you travel across the -sheet: A ───────────────── B But if you fold -the paper so A and B touch, then poke a tunnel through: A ● - \____ - \____ ● B That tunnel is the basic idea of a wormhole. -🕳️🌌 In Einstein's general relativity, space and time aren't -just an empty stage. They're a thing called spacetime, which can -curve and distort. The equations allow certain geometries where -two distant regions could theoretically be connected by a throat -or tunnel. The important distinction is: Black hole: stuff can -fall in, and under ordinary physics it can't come back out. -Wormhole: theoretically could have an entrance and an exit, -connecting two different places. Some wormhole solutions could -even connect different times, not just different locations. -That's where things get extra spicy. 🧪 The catch is enormous: -we've never observed a wormhole, and we don't know whether -traversable ones can actually exist. The classic Einstein-Rosen -bridge collapses too quickly to travel through. Keeping one open -appears to require something resembling negative-energy "exotic -matter," and we don't know whether nature permits enough of that -to build a usable wormhole. So wormholes aren't pure sci-fi -nonsense. They come out of legitimate equations in physics. But -right now they're basically: Mathematically allowed. Physically -unconfirmed. Engineering department unavailable. And the really -wild part is that wormholes, black holes, and quantum -entanglement may be connected in surprisingly deep ways in -modern theoretical physics. What about AI and agents and -software? I wonder if these could philosophically and quantumly -be entangled. Yes, philosophically, absolutely. Literally -quantum-entangled, almost certainly not in the sense physicists -mean. That distinction is the fun part. 🧠⚛️🕸️ With AI agents -and software, you can get something that looks eerily like -entanglement because separate systems become correlated through -shared context, memory, tools, APIs, logs, prompts, and feedback -loops. Two agents might act independently, yet their behavior is -coupled because they are reading the same world-state or -modifying the same environment. Change one thing, and the other -agent’s future behavior changes. That is not quantum -entanglement. It is closer to informational entanglement or -causal coupling. Imagine Agent A writes to a database. Agent B -reads that database. Agent B changes a GitHub issue. Agent C -reads the issue and changes code. Then A later observes the code -and updates its beliefs. You get a loop like: Agent A → world -state → Agent B - ↑ ↓ memory ← software ← Agent C At some point, asking -“which agent caused this outcome?” becomes weirdly difficult. -The system has a distributed causal history. The agents are no -longer cleanly separable. That has a strong philosophical -resemblance to entanglement. There is another connection that I -think is even more interesting: software agents increasingly -behave like observers inside a world. An agent does not directly -perceive reality. It gets observations: reality - ↓ API / sensors / files / messages ↓ agent context ↓ -internal model - ↓ action ↓ reality changes That loop is structurally similar -to some of the philosophical questions surrounding quantum -measurement: What counts as an observer? When does information -become definite? Does observation merely reveal a state, or -participate in creating the state that matters? In software, the -answer can literally be "both." Suppose an agent checks whether -a deployment succeeded. Its observation might trigger another -tool call, which changes the deployment, which changes what the -next agent sees. So observation becomes participation. And then -you get something wormhole-ish too. 🕳️ Agents create shortcuts -through huge informational distances. Before agents: human → -search → read 40 files → understand architecture → modify -code With a sufficiently capable agent: intent → agent → -modification The agent effectively compresses a giant path -through information space. Not a spacetime wormhole, obviously, -but conceptually it is an epistemic wormhole: a shortcut between -a question and some previously distant piece of knowledge or -capability. That's arguably what software itself has always -done. A function call is a tiny abstraction wormhole: -send_email() Behind those 12 characters might be DNS, TLS, -authentication, networking, distributed servers, storage, -queues, and a thousand layers of machinery. You don't traverse -them. You enter one end of the abstraction and pop out the -other. Agents push this idea much further because the -abstraction can now be semantic rather than procedural. You say: -"Figure out why production is slow and fix it." And potentially -thousands of computational steps occur behind that single -sentence. That is a bizarre new kind of compression of -causality. Where things get really spicy is multi-agent systems. -If agents develop shared memories, mutually model each other, -modify shared environments, and recursively delegate work, then -the proper unit of analysis might stop being: Agent A and -become: Agent A + Agent B + tools + memory + environment In -philosophy, this starts brushing against ideas like the extended -mind and distributed cognition: maybe the thinking system isn't -confined to one brain or one model instance. For an AI system, -the "mind" might actually be: LLM + context + memory + terminal -+ internet + codebase + other agents + humans That's less a -chatbot and more a cognitive field. And that is where your -quantum analogy becomes genuinely useful, provided we keep it -metaphorical. You could describe sufficiently interconnected -agents as having non-independent informational states. Once -they've interacted enough, describing one agent without -describing its relationships to the others loses important -information. Which sounds suspiciously close to the intuitive -description of entanglement: the whole contains information that -cannot be reduced cleanly to the individual parts. Physics has -an extremely precise mathematical meaning for that sentence. AI -does not. But philosophically? There's something there. 🧪 The -rabbit hole I'd go down next is actually agents + Wheeler's -"participatory universe" + extended mind + distributed systems. -Those four ideas collide in a surprisingly coherent way. Yeah. -After looking at Agent AFK as it exists right now, my answer is: -We are already partway there 🧠🕸️ Not quantum-entangled in the -physics sense. AFK runs on classical computers, so there is no -literal quantum entanglement happening between agents. But the -software architecture is already surprisingly close to the -philosophical thing we were describing. AFK currently has: -isolated child agents that fork from a parent and run -independently parallel and background agents a compose DAG where -agent work can explicitly depend on other agent work persistent -background jobs shared cross-session memory traces containing -tool calls, decisions, subagent lifecycles, cost, etc. -adversarial /shadow-verify /mint, /diagnose, /research, /review, -etc. orchestrating waves of specialized agents afk farm, where -multiple independent realities of the same coding task literally -run in separate git worktrees and AFK evaluates which reality -won 😭 That last one is especially funny given this -conversation. AFK's docs explicitly describe subagents as -independent sessions with zero inherited conversational context, -whose compressed results flow back into the parent. And compose -already lets up to 20 agents form an explicit dependency graph -where some agents' execution depends on the completion of -others. Meanwhile AFK's memory already provides a persistent -informational environment shared between REPL, daemon, chat, and -Telegram sessions. So conceptually: - MEMORY - ↙ ↓ ↘ - Agent Agent Agent - A B C - ↘ ↓ ↙ ARTIFACTS - ↓ - WORLD/REPO - ↓ - TRACE - ↓ - future agents That is distributed cognition. But -there's one piece missing that I think could genuinely become a -major architectural idea for AFK. Give AFK a shared world state -Today, AFK is mostly: agents exchanging messages The next level -would be: agents inhabiting the same evolving informational -environment. Think of it as a blackboard or world model. Instead -of Agent A returning: "I discovered that auth.ts has a race -condition." to the parent as text, Agent A could publish an -actual structured object: Claim #81 type: finding subject: -src/auth.ts claim: refresh token rotation has a race condition -confidence: 0.91 evidence: - - src/auth.ts:142-177 - test/auth-refresh.test.ts:88 -created_by: agent-a depends_on: - - observation-72 Now Agent B can independently discover: Claim -#94 contradicts: claim-81 confidence: 0.76 ... Agent C, the -verifier, sees both. And suddenly AFK has something much more -interesting than a bunch of conversations. It has an epistemic -state. This is the missing "entanglement layer" Imagine every -AFK run having: WorldState │ ├── Facts ├── Claims ├── -Hypotheses ├── Decisions ├── Artifacts ├── Tasks ├── -Evidence └── Relationships Every object knows: created_by -observed_by modified_by depends_on contradicts supports -derived_from supersedes confidence timestamp version Now -something genuinely cool happens. Suppose: Agent A - ↓ Claim X ↓ Agent B ↓ Decision Y ↓ Agent C ↓ Code change -Z Then Agent D later disproves Claim X. AFK can know: 💀 Hold -on. Decision Y and code change Z depended on something that is -no longer believed to be true. And automatically wake the -affected agents: Claim X invalidated - ↓ Decision Y stale ↓ Code Z needs re-verification ↓ -dispatch verifier That is the feature I would build. Because now -the agents aren't merely parallel workers. Their informational -states become causally coupled. And this plugs directly into -things you've already built You don't need to rewrite AFK. The -existing architecture actually gives you most of the bones. -compose Currently: A ───┐ - ├── C B ───┘ Great. Add semantic dependencies: Agent -A - ↓ writes Finding #12 ↓ consumed-by Agent C The DAG becomes -more than execution scheduling. It becomes a causal graph. -Background agents Already independent, persistent jobs. Instead -of simply eventually dumping their result into context: -background agent - ↓ world-state update ↓ subscribers notified Now agents -don't have to know each other exist. They communicate through -reality. That's much closer to how humans, organizations, ant -colonies, markets, and distributed systems behave. Memory Your -current hot memory + SQLite fact archive is already basically -the long-term layer. I'd separate: HOT.md / memory.db - │ │ long-term ▼ - Persistent Memory world-state.db - │ │ current run/project ▼ - Working Reality Memory is: What have we learned historically? -World state is: What do we currently believe is happening?

AFK could literally traverse the -provenance graph: edit 28 because decision 22 because evidence -13 + 14 generated by agents B + C in response to task 4 which -came from user request 1 That's a mechanical chain of causation. -Very different. Then afk farm gets bonkers You already run -multiple implementations in separate worktrees and rank them. -Currently those are effectively: World 1 → solution A World 2 -→ solution B World 3 → solution C That's basically -counterfactual computation. Not quantum many-worlds. 😭 But -philosophically: AFK literally forks several possible futures of -the codebase, observes each outcome, and selects one reality to -continue.

But internally, the philosophical -analogy is productive. I would use existing computer-science -language: Shared world model Causal graph Provenance graph -Blackboard architecture Reactive multi-agent state And perhaps -use the more exotic language when explaining why the -architecture is interesting. The actual AFK evolution I see -Today: - Agent AFK Human - ↓ Parent Agent ↓ subagents ↓ tools ↓ code Next: - Human - │ ▼ - ┌───────────┐ │ AFK World │ │ - State │ └───────────┘ - ↙ ↓ ↘ - / │ \ - ▼ ▼ ▼ - Agent Agent Agent - A B C │ │ │ └──┬──┴──┬──┘ - │ │ ▼ ▼ - evidence code - │ │ └──┬──┘ - ▼ - AFK World - State - │ - state changed - │ - relevant agents - wake up The parent is no longer the brain. AFK -itself becomes the cognitive substrate. The agents are transient -processes inside it. That is the leap. And I actually think it -fits AFK's core thesis freakishly well: The model isn't the -product. The loop is. I'd push that one step further: -Eventually, the agent isn't the system. The world it inhabits -is. That's where I think AFK can go next. 🧪🕸️ And what about -the wormholes? Yeah. The wormhole analogy may actually be more -useful for AFK than the entanglement analogy. 🕳️🧠 Again, not -literal spacetime wormholes. But software has a very real -concept of distance, and agents spend enormous amounts of -computation crossing it. Think about an AFK agent trying to fix -something. The relevant information might be scattered across: -300 files ↓ Git history ↓ old session ↓ another subagent's -findings ↓ an issue ↓ a database ↓ a production log ↓ a -decision from three weeks ago Normally the agent must traverse -that informational space. A software "wormhole" would let it -jump directly between things that are far apart structurally but -close semantically or causally. Example Agent A discovers: -refreshSession() fails because of a design decision made two -weeks ago. Instead of Agent B doing this: search repo → grep -files → inspect history → search memory → find previous -session → understand decision AFK could already know: -src/auth/session.ts:183 - ↕ wormhole Decision #42: "Refresh tokens rotate before -persistence" Session: 91ab2 Agent: planner-3 Evidence: ... The -physical/informational distance might be enormous. But the -causal distance is one edge. That's your wormhole. AFK could -have several kinds 🧠 Context wormholes Jump between -semantically related information. error - ↕ previous occurrence ↕ fix ↕ relevant procedure Instead of -shoving everything into the context window, AFK exposes -shortcuts. This is basically context virtualization. The model -sees a small local neighborhood, with portals into distant -information. 🔗 Causal wormholes These are even cooler. From: -code change directly to: why this exists Example: function foo() - │ ▼ introduced by commit 84 │ ▼ because Decision #17 │ - ▼ -because Finding #9 - │ ▼ because user requested X The agent can travel -backward through AFK's causal history. And forward: Finding #9 -was disproven - ↓ show me everything downstream ↓ Decision #17 ↓ -files A, B, C - ↓ tests D, E That's an extremely practical -"wormhole." ⏳ Temporal wormholes AFK already has persistent -memory and traces. Imagine: afk wormhole "when did we last solve -this?" And AFK opens a live contextual bridge into an old -session. Not just search results. It reconstructs the relevant -state: Past AFK state - │ │ compressed portal ▼ Current agent context The agent -effectively asks its past self: What did you know when this -decision was made? That's far richer than ordinary memory -retrieval. And farm already resembles one You have several -branches of possible future state: - NOW - │ - ┌───────┼───────┐ ▼ ▼ ▼ - A B C Normally they're separate universes. A wormhole -could allow controlled information exchange between those -universes without merging their code. For example: World A -discovers: "SQLite locking is the problem." - 🕳️ World B receives only that finding while preserving -its independent implementation. That could make afk farm much -smarter. Right now parallel approaches risk either being -completely isolated or contaminating each other. A controlled -wormhole gives you: selective cross-branch information transfer. -That is actually a legit multi-agent research technique. So -combine the two ideas Entanglement describes relationships: -These agents/states can no longer be fully understood -independently. Wormholes describe connectivity: Two distant -regions of the system can communicate through a much shorter -informational path. Put those together: - AFK WORLD - Agent A ─────── Claim 17 - │ │ │ │ causal │ │ entanglement ▼ ▼ - Artifact X ─── Decision 23 - │ │ - 🕳️ wormhole - │ ▼ - Old Session 481 - │ ▼ - Agent B And suddenly AFK isn't merely: model + -tools + subagents. It's a graph-shaped information space that -agents move through. The practical implementation I wouldn't -actually add some goofy QuantumWormholeManager.ts. 😂 The sane -implementation is a typed graph layer: Node ├── Agent ├── -Session ├── Claim ├── Observation ├── Decision ├── -File ├── Commit ├── ToolCall ├── Artifact └── Task -Edge ├── caused_by ├── depends_on ├── derived_from -├── contradicts ├── supports ├── modified ├── -observed ├── supersedes └── related_to Then a "wormhole" -is simply an important nonlocal edge surfaced to the model. -Instead of providing 100,000 tokens: Here is everything. AFK -provides: Here is what matters locally. There are 7 relevant -portals if you need them. That's potentially much more scalable -than gigantic context windows. And that might actually be the -deepest version of this idea: Context windows make the universe -bigger. Wormholes make distance matter less. For an agent -harness, I suspect the second one is ultimately more powerful. -🕳️⚡ Is there anything else we should be thinking about or -looking at or doing? Yes. A few things are worth taking -seriously, and one of them is almost comically on-the-nose. 1. -Look at ActiveGraph before building anything There is already an -open-source project called ActiveGraph whose thesis is -basically: the graph is the world, behaviors react to changes, -and the event log is the source of truth. Its runtime uses typed -graph objects, typed relations, an append-only event log, -reactive behaviors, deterministic replay, and the ability to -fork a run at any historical event and diff the resulting -futures. That is extremely close to what we independently -arrived at for AFK. AFK idea ActiveGraph idea world state ←→ -graph causal history ←→ event log entanglement ←→ typed -relations wormholes ←→ nonlocal graph edges agents reacting -←→ behaviors/subscriptions AFK farm ←→ fork + replay + diff -trace ←→ authoritative history I would not replace AFK with -it. AFK's identity is different. It's a coding-agent harness -with models, permissions, CLI/daemon/Telegram, orchestration, -memory, skills, verification, worktrees, etc. But I would study -ActiveGraph's internals closely and potentially steal/adapt some -architectural patterns. It's Apache-2.0 too. That should -probably be step zero. 2. The trace should perhaps become the -source of truth This is the biggest architectural thought I have -now. AFK currently has: agent runs - ↓ state changes ↓ trace records what happened Consider -flipping it: - EVENT LOG - │ - ┌──────────┼─────────┐ ▼ ▼ ▼ - world state trace memory - │ ▼ - agents Meaning: everything important becomes an event. -TaskCreated AgentSpawned ObservationMade ClaimCreated ToolCalled -FileModified ClaimContradicted DecisionMade TestPassed -AgentFinished Then your current world state is merely: the -projection of all events up to time t. This buys AFK something -enormous: Time travel afk state --at event:481 Replay -Reconstruct exactly what AFK believed at some point. Forking - event 481 - │ - ┌──────┴──────┐ ▼ ▼ - history A history B Counterfactuals "What if we had -chosen the other architecture?" Fork at the decision. Run it. -Compare. AFK Farm becomes temporal instead of merely -Git-oriented. ActiveGraph is already demonstrating precisely why -this model is useful. 3. Don't store "facts." Store epistemic -objects. This is a subtle one. Current agent memory often -collapses everything into: "User uses SQLite." But the universe -is messier. AFK should eventually distinguish: Observation Claim -Hypothesis Decision Preference Inference Evidence Prediction -Assumption Because these aren't equivalent. Imagine: OBSERVATION -Test failed three times. - ↓ supports HYPOTHESIS The connection pool leaks. ↓ - motivated -DECISION Replace connection manager. - ↓ caused CODE CHANGE src/db/pool.ts Then someone -discovers: NEW OBSERVATION Failure was caused by test pollution. -AFK knows what needs reconsidering. Recent research is -converging on exactly this. MemIR, for example, argues that flat -text memory can collapse source distinctions and instead -separates evidence, retrieval cues, and truth-bearing claims. -And MAP-Graph, posted August 11, models agents, sources, -memories, claims, and actions in a typed execution graph, then -carries provenance and trust through the derivation chain. -That's damn near our conversation written as a paper. 🧪 4. -Wormholes need a routing system This is one thing I would add -beyond what we discussed. A wormhole shouldn't merely be: node A -───────── node B AFK should answer: Which distant -information is worth creating a shortcut to? Think of a model's -context as its local spacetime. AFK could dynamically construct: - current task - ● - / | \ - / | \ - local local local - 🕳️ 🕳️ - ↓ ↓ - old decision old bug The model gets the local -neighborhood automatically. Then AFK offers nonlocal edges only -when they have high: relevance × causal importance × confidence -× recency/validity × trust -──────────────────── context cost That's -potentially an attention router above the LLM. And that could be -a genuinely meaningful AFK differentiator. 5. Add validity over -time This is easy to overlook. A claim shouldn't just be: Skya -uses X. It might be: Claim: - X valid_from: event 918 valid_until: event 1322 superseded_by: -claim 551 Same for software: "We deploy on Vercel" could be true -today and false three months later. The memory problem becomes: -What was believed at this point in history? Not merely: What -memories match this embedding? Recent long-horizon memory work -is explicitly starting to test validity intervals and -time-dependent facts, and graph/provenance approaches appear -particularly useful as histories grow. This fits the wormhole -idea beautifully: Temporal wormhole Current code - │ 🕳️ │ AFK state when this line was originally written -That could be insanely useful for debugging. 6. Think about -stigmergy, not just communication There's another conceptual -leap. Agents don't necessarily need: Agent A → message → Agent -B They can coordinate by changing the environment. Agent A - ↓ world changes ↓ Agent B notices ↓ world changes ↓ Agent -C notices That's essentially the blackboard pattern. Modern LLM -multi-agent research is revisiting this because shared-state -coordination can outperform rigid parent/subordinate -orchestration in some settings. For AFK that could mean: Agent -security-auditor creates Finding #712 - ↓ event verification agent wakes ↓ creates -Verification #803 - ↓ event fix agent wakes ↓ Patch #991 ↓ event test -agent wakes Nobody explicitly told the next agent what to do. -The state transition caused the next computation. That's much -closer to a living software system than today's parent → -Task(subagent) architecture. 7. Agent identity and lineage could -become important Right now a child agent is basically ephemeral. -But eventually you may want: Agent ├── identity ├── role -├── capabilities ├── model ├── trust history ├── -ancestors ├── memories └── previous performance Then: -Agent 81 - ↓ forked Agent 94 ↓ spawned Agent 127 You get agent -lineage. Not because we need cute personalities. Because AFK -could learn: descendants of this debugging strategy tend to -solve concurrency bugs well. Now orchestration itself becomes -learnable. 8. AFK should probably support A2A eventually This is -much more mundane, but strategically important. AFK already -speaks MCP for tools. The emerging division is becoming: MCP -Agent ↔ tools/resources A2A Agent ↔ agent A2A 1.0 now defines -discovery, capabilities, collaborative tasks, artifacts, -stateful task lifecycles, and communication between opaque -independent agents. If AFK grows its agent model, I would not -invent a proprietary network protocol first. Internally: AFK -native agents Externally: AFK agent - ↕ A2A other agent systems Then AFK's "world" can eventually -have agents that don't even run inside AFK. That gets wild. 9. -MCP itself has moved in a relevant direction The latest MCP -spec, released July 28, 2026, moved to a stateless core and -promoted long-running work into a Tasks extension. That's worth -watching closely because AFK already has long-running -daemon/background semantics. Rather than fighting standards, I'd -make: - AFK - ┌──── World Graph ────┐ │ │ ▼ ▼ - native agents remote agents - │ │ │ A2A │ - tools - │ - MCP That's a pretty elegant architecture. 10. The -deepest thing: the model stops being the persistent entity This -is where all the threads converge. Today we tend to think: Agent -AFK is an agent that has memory. I think the more interesting -future conception is: AFK is a persistent computational world in -which agents temporarily exist. Models can come and go. Opus -Sonnet GPT Kimi future model X Doesn't matter. The persistent -thing is: - AFK WORLD - │ - ┌──────────┼──────────┐ │ │ │ - history beliefs artifacts - │ │ │ - events claims code - │ │ │ - lineage evidence decisions - └──────────┼──────────┘ - │ - wormholes - │ - AGENTS That makes your existing tagline even more -profound: The model isn't the product. The loop is. I think the -eventual version might actually be: The model isn't the agent. -The world is. What I would actually do now I wouldn't start -coding the whole thing yet. I'd do one architectural -exploration. Take AFK's existing: trace + memory + compose + -subagents + farm and write an RFC for an event-sourced typed -world graph underneath them. The first prototype only needs -maybe six node types: Task Agent Observation Claim Decision -Artifact and six relations: created supports contradicts -depends_on caused supersedes Then prove three things: 1. Causal -explanation Why did AFK make this edit? 2. Wormhole retrieval -Show the most relevant nonlocal context for this failing test. -3. Temporal fork Rewind before Decision X, take alternative Y, -and compare outcomes. If those three demos work, we haven't just -added another AFK feature. -We may have found the architecture for what AFK becomes next. 🕳️🕸️🧠 diff --git a/.afk/research/epistemic-world-graph-research-brief.md b/.afk/research/epistemic-world-graph-research-brief.md deleted file mode 100644 index d12b5d795..000000000 --- a/.afk/research/epistemic-world-graph-research-brief.md +++ /dev/null @@ -1,131 +0,0 @@ -# Shared Agent State — Research Brief - -*Generated 2026-08-18 from ChatGPT transcript + parallel research wave + adversarial review* - -## The Problem - -AFK's agents can exchange results through parent orchestration and DAG dependencies, but do not inhabit a persistent shared working state.

This wiring needs to happen at the surface bootstrap level (interactive.ts, telegram handler, chat command, farm runner). diff --git a/scripts/ab-results/arm-a-dedup-20260820T164953Z.json b/scripts/ab-results/arm-a-dedup-20260820T164953Z.json deleted file mode 100644 index a4435253e..000000000 --- a/scripts/ab-results/arm-a-dedup-20260820T164953Z.json +++ /dev/null @@ -1,13 +0,0 @@ -{ - "tracePath": "/Users/griffinlong/.afk/state/witness/0db15163-4041-443b-bffa-624f2e236af0/trace.jsonl", - "toolFilter": "read_file only", - "totalCalls": 0, - "uniqueFingerprints": 0, - "crossAgentDuplicates": 0, - "selfDuplicates": 0, - "crossAgentDedupRatio": 0, - "distinctAgents": 0, - "hotFingerprints": [], - "skippedNoFingerprint": 0, - "totalToolCallStarted": 0 -} diff --git a/scripts/ab-results/arm-a-dedup-20260820T164953Z.txt b/scripts/ab-results/arm-a-dedup-20260820T164953Z.txt deleted file mode 100644 index c59fe33ca..000000000 --- a/scripts/ab-results/arm-a-dedup-20260820T164953Z.txt +++ /dev/null @@ -1,13 +0,0 @@ - -╭─ Read Deduplication Report ────────────────────────────────╮ -│ Trace: /Users/griffinlong/.afk/state/witness/0db15163-4041-443b-bffa-624f2e236af0/trace.jsonl -│ Filter: read_file only -│ Agents: 0 -╰────────────────────────────────────────────────────────────╯ - - Total calls: 0 - Unique fingerprints: 0 - Cross-agent duplicates: 0 (sibling read same file) - Self-duplicates: 0 (same agent repeated) - Cross-agent dedup ratio: 0.0% - diff --git a/scripts/ab-results/arm-a-output-20260820T164953Z.json b/scripts/ab-results/arm-a-output-20260820T164953Z.json deleted file mode 100644 index f4a89d4f9..000000000 --- a/scripts/ab-results/arm-a-output-20260820T164953Z.json +++ /dev/null @@ -1 +0,0 @@ -- Initializing agent... diff --git a/scripts/ab-results/arm-b-dedup-20260820T164953Z.json b/scripts/ab-results/arm-b-dedup-20260820T164953Z.json deleted file mode 100644 index 13c6260ed..000000000 --- a/scripts/ab-results/arm-b-dedup-20260820T164953Z.json +++ /dev/null @@ -1,13 +0,0 @@ -{ - "tracePath": "/Users/griffinlong/.afk/state/witness/c78c630c-1bca-45de-a13c-cb1fad1880f2/trace.jsonl", - "toolFilter": "read_file only", - "totalCalls": 0, - "uniqueFingerprints": 0, - "crossAgentDuplicates": 0, - "selfDuplicates": 0, - "crossAgentDedupRatio": 0, - "distinctAgents": 0, - "hotFingerprints": [], - "skippedNoFingerprint": 0, - "totalToolCallStarted": 0 -} diff --git a/scripts/ab-results/arm-b-dedup-20260820T164953Z.txt b/scripts/ab-results/arm-b-dedup-20260820T164953Z.txt deleted file mode 100644 index 5806ba43f..000000000 --- a/scripts/ab-results/arm-b-dedup-20260820T164953Z.txt +++ /dev/null @@ -1,13 +0,0 @@ - -╭─ Read Deduplication Report ────────────────────────────────╮ -│ Trace: /Users/griffinlong/.afk/state/witness/c78c630c-1bca-45de-a13c-cb1fad1880f2/trace.jsonl -│ Filter: read_file only -│ Agents: 0 -╰────────────────────────────────────────────────────────────╯ - - Total calls: 0 - Unique fingerprints: 0 - Cross-agent duplicates: 0 (sibling read same file) - Self-duplicates: 0 (same agent repeated) - Cross-agent dedup ratio: 0.0% - diff --git a/scripts/ab-results/arm-b-output-20260820T164953Z.json b/scripts/ab-results/arm-b-output-20260820T164953Z.json deleted file mode 100644 index f4a89d4f9..000000000 --- a/scripts/ab-results/arm-b-output-20260820T164953Z.json +++ /dev/null @@ -1 +0,0 @@ -- Initializing agent... diff --git a/scripts/ab-results/comparison-20260820T164953Z.md b/scripts/ab-results/comparison-20260820T164953Z.md deleted file mode 100644 index b959ccdf9..000000000 --- a/scripts/ab-results/comparison-20260820T164953Z.md +++ /dev/null @@ -1,34 +0,0 @@ -# Workspace A/B Experiment — 20260820T164953Z - -## Setup -- **Model**: sonnet -- **Max turns**: 25 -- **Budget**: $3 -- **Task**: Parallel 3-agent provider retry investigation (compose tool) -- **Repo**: agent-afk @ 50000443 - -## Results - -| Metric | Arm A (Control — No Workspace) | Arm B (Treatment — Workspace) | -|---------------------------|-------------------------------|-------------------------------| -| Wall-clock time | 0s | 0s | -| Distinct agents | 0 | 0 | -| Total read_file calls | 0 | 0 | -| Cross-agent duplicates | 0 | 0 | -| **Cross-agent dedup ratio** | **0.0%** | **0.0%** | - -## Sessions -- Arm A: `0db15163-4041-443b-bffa-624f2e236af0` -- Arm B: `c78c630c-1bca-45de-a13c-cb1fad1880f2` - -## Interpretation -A **lower** cross-agent dedup ratio in Arm B means the workspace successfully -reduced redundant file reads across sibling agents.
