feat(benchmark): add the Toolathlon adapter

[zhenxi0901]

Summary

Adds Toolathlon (hkust-nlp/Toolathlon) as a benchmark: benchmark.type: "toolathlon", driven through the existing Sandbox capability, with the Hermes or OpenClaw harness as the agent loop reaching Toolathlon's MCP gateway over the sandbox's task-sandbox alias. One task (canvas-list-test) has run end to end on each harness — prepare, agent, both isolation gates, grade, clean teardown.

Implementation Notes ⚒️

What is reused. Toolathlon's own "decoupled" runner already splits a task into an in-container preprocess and MCP gateway, an external agent loop, and an in-container grader. pkg/benchmark/toolathlon drives the two container halves through Exec/Upload/Download and leaves the agent loop to the harness:

• PrepareSandbox: installs the pinned project tree and task directory (one tar upload), runs container_preprocess, validates the task bundle it writes, stashes the grader and ground truth into the private run directory and proves them absent, then starts container_tool_gateway on a fixed port and waits for /health.
• Evaluate (after harness stop and bridge revocation): discards agent-planted grader paths, restores the stash, extracts the pinned project code again from the re-verified host checkout (so container_eval and everything it imports are not what the agent left; the task directory stays as restored, because preprocess writes ground truth there), checks the evaluator's runtime (uv, the interpreter, the virtualenv, uv's config files, the project's top-level files; bytecode caches and log files excluded) against a file-by-file inventory taken before the bridge existed — a small Python program on the image's system interpreter that releases what it read from the page cache — and refuses to grade on any difference, re-injects the trusted bundle, runs container_eval with a private bytecode cache prefix and no user site, and scores from its verdict file. Evaluation status semantics follow terminalbench. What is and is not covered by this is spelled out in the guide's evaluation section.
• The gateway is registered with the harness by wiring itself (toolathlon.Gateway): Hermes renders it under mcp_servers (pkg/harness/hermes), OpenClaw under its native mcp.servers plus the bundle-mcp sandbox-gate entry without which OpenClaw loads the server and filters its tools out of the sandboxed session (pkg/harness/openclaw) — the same way web_search reaches DRB's SearXNG; a profile names no server for it. harness.mcp.servers is a new optional block for a profile's own extra MCP servers on either harness and may not use the reserved name toolathlon.

Two upstream assumptions handled inside the sandbox rather than by weakening it (talking points):

1. Host networking. Toolathlon starts its container with --network host and every one of its configs reaches the self-hosted applications (Canvas, poste.io, WooCommerce) at localhost:<fixed port>. For tasks that need one, the adapter starts a small stdlib-only Python loopback forwarder inside the task container that carries those seven ports to the container's default gateway (the Docker host on a bridge network). Toolathlon's files are used unmodified. Verified on a fresh bridge network before the run.
2. Grader hiding. Toolathlon hides its grader with docker cp while the agent runs. The adapter ports the policy (its protected-name list, required evaluation/, type checks, case-insensitive README.md) onto the Terminal-Bench 2 mechanism: archive → Download → remove → prove absent before the bridge exists; restore only in Evaluate.

Task selection. 53 of the 108 tasks load with no account at the pinned revision (28 need nothing outside the sandbox and the applications, 25 also reach the public internet). Fifty more need a third-party account (GitHub, Google, Hugging Face, Notion, Snowflake, W&B, YouTube): they load when benchmark.toolathlon.credentials_dir names a directory holding Toolathlon's filled token_key_session.py and the key files it names (the checkout's copy stays at the example; the directory is overlaid on the sandbox's configs/ at preparation and again after the evaluate-time reinstall), and task load refuses a task naming the fields the directory does not provide. The five k8s tasks (a kind cluster needing the Docker socket and host networking) are refused with the reason. A task's local tools are mapped onto the harness (python_execute/sleep → the terminal; web_search → refused unless harness.web_search is enabled). Application-backed and account-backed tasks are accepted only at execution.concurrency 1, because every sandbox forwards to the one deployment (or the one account) and a task's preprocess resets its state. The Benchmark interface is unchanged: the trajectory container_eval reads is a stub, because it takes the config from the trusted bundle and the status from the caller, and no pinned grader reads the messages.

Commits (in order; happy to squash). The first three are the adapter; the rest answer review rounds, one commit each, and are described in their messages:

• feat(benchmark): add the Toolathlon adapter — the package, Hermes MCP block, config/versions/wiring, profile, tests, docs, .agents/TASKS.md R23.
• fix(model): accept DeepSeek's current flash model ID — found by running the profile: DeepSeek's /models now lists deepseek-flash (and deepseek-v4-pro), not deepseek-v4-flash, so every checked-in DeepSeek profile fails preflight with model_missing today. The current ID is accepted in preflight and in OpenClaw's thinking switch; old names kept; test extended.
• fix(toolathlon): absolute tool paths for the sandbox — Exec rejects bare command names; uv lives on the image's PATH, so it is resolved by /bin/sh with positional arguments.

Verification. make lint, make build, go test ./..., make test-race pass. aries setup profiles/hermes-toolathlon-canvas-list-test-deepseek.json installs the pinned checkout (594 MB, shallow) and materializes the two gitignored site configs Toolathlon's scripts import. The real run: preprocess seeded Canvas through the forwarder, Hermes made 55 tool calls (30 via the gateway, 25 via the SSH bridge) in 119 s, isolation confirmed, grader ran in 4.7 s, no container or network left behind; verdict fail-by-one-row, which is the grader's judgement of the agent, not a pipeline fault. Later commits were each verified the same way plus an end-to-end run where the change touched the run path (the review threads say which). The evaluation-path commit was verified on the two tasks its defects had hit (sales-accounting graded 1 after being refused for the excel server's log; woocommerce-update-cover graded 1 after grading 0 with the overwritten ground truth). The OpenClaw commit was verified on canvas-list-test with profiles/openclaw-toolathlon-canvas-list-test-deepseek.json (OpenClaw 2026.7.1): 88 tools in the session, 63 gateway calls, graded; the verdict was the grader's row-count judgement, as on Hermes. The credentials commit was checked against the real checkout with a GitHub task: refused without a directory (naming the setting), refused with the example's placeholders (naming the field), and with a dummy token it loaded, the overlay reached the sandbox and preprocess failed closed on GitHub's 401 before any model call, with no archive left on the host and the token in no log.

The package's tests include a scripted-sandbox flow test that asserts the order of every preparation and evaluation step, fail-closed behaviour on preprocess failure and gateway timeout, that an agent-planted evaluation/ or readme.MD is discarded before restore, that a rewritten evaluator cannot produce the pass it would have written, and that an altered runtime is refused with the paths named. Guide: docs/benchmarks/toolathlon.md.

External Dependencies 🍀

• Toolathlon checkout pinned in configs/versions.json (hkust-nlp/Toolathlon @ 9be8d8fe…); cloned by aries setup like the other benchmarks.
• Toolathlon's task image docker.io/lockon0927/toolathlon-task-image:1016beta (the profile's benchmark.environment.image).
• For application-backed tasks, the matching Toolathlon deployment (deployment/canvas, deployment/poste, deployment/woocommerce in the pinned checkout) running on the Docker host and publishing its fixed ports. ARIES does not start these.
• No new Go dependencies.

Breaking API Changes ⚠️

• None. New optional profile blocks: harness.mcp (Hermes or OpenClaw; a profile's own extra servers), benchmark.toolathlon (gateway_port, app_host, max_steps, credentials_dir), versions.toolathlon (required only when the benchmark is selected). Options.MCPServers on the OpenClaw harness.

Rebased onto main (the TASKS.md conflict with #50 was the only one) and completed the verification I had listed as pending:

• make lint, make test-race: pass.
• make integration: passes. On a fresh host the OpenClaw package first failed because the Terminal-Bench 2 checkout its fix-git test expects was not installed; after aries setup with a TB2 profile it passes. That is an environment prerequisite, not something this branch changes.
• Final Docker inspection after both suites: no ARIES containers or networks left.

The adapter commit was amended to record this in .agents/TASKS.md and to fix two things CI caught on the first push (the checked-in profile count after #50's new profile, and one word aspell rejects). CI is green.

[zhenxi0901]

On the out-of-diff point about bearer tokens over plain-HTTP endpoints in internal/app/preflight.go: that is the model preflight's existing policy (HTTP kept for the documented local SGLang and vLLM deployments), which this PR does not change — its only edit there adds DeepSeek's current model ID to the accepted list. It reads as a separate change to the preflight's endpoint policy rather than part of the Toolathlon adapter, so I have left it out of this PR; happy to open an issue for it if the maintainers want it tracked.

[zhenxi0901]

Rebased onto current main (the merge commit from 14 Sep is replaced by the same five commits on top of 4431edd; conflicts were in wiring.go, pkg/config, the Hermes harness/config and docs/supported.md, all resolved by keeping both sides — the MCP field sits alongside the new compaction and hermes blocks, and the checked-in profile count is now 14). make lint, make test and make test-race pass.

Since main now pins Hermes v2026.8.31, I ran canvas-list-test end to end on the rebased branch with that image: preparation, gateway, agent and evaluation all as before. One observable difference worth knowing: 8.31 lists MCP tools as mcp____ behind its tool_describe/tool_call pair rather than registering each as mcp__, so the trajectory shows tool_call entries with the MCP name as an argument. The adapter needs no change for it; the last commit adds a sentence to docs/benchmarks/toolathlon.md and to the MCPServer comment saying so.

Security Misconfiguration

Reachability: Internal
Exploitability: Moderate
CWE: CWE-319 — Cleartext Transmission of Sensitive Information

Require HTTPS for remote MCP servers. Both MCP validators accept cleartext HTTP, and the configured URL is passed directly to Hermes.

[Pwspang]

Does Toolathon already expose which MCP is needed for a certain task, if so, do we need to expose the configuration of mcp servers to the user?

[zhenxi0901]

Two different layers. The task's needed_mcp_servers are the backend servers (canvas, filesystem, ...) that Toolathlon's gateway aggregates inside the sandbox; the user never configures those. The profile entry was only the client-side pointer to the gateway, and since the adapter fixes both the host and the port, there was nothing to write there but the same URL. Changed in 9f9cc25: wiring adds the gateway entry itself for benchmark.type: toolathlon; harness.mcp is now optional and only for a profile's own extra servers; an entry named toolathlon is rejected.

[Pwspang]

Does this mean that only a selected subset of task can be run, not the full 108 tasks

[zhenxi0901]

Yes. 53 of the 108 load: the 28 fully offline tasks (local tools + the three self-hosted apps) and 25 that also reach the public internet. The other 55 need a credentialed third-party account (Google, Notion, GitHub, HF, Snowflake, W&B, YouTube) or the k8s host runtime and are refused at task load with the server named. Running those would mean provisioning the accounts per run, which isn't reproducible here.

Checking the count turned up a bug: the catalogue map was keyed by config filename, but tasks cite the name: inside the file, and five differ (npx-fetch.yaml is fetch, scholarly_search.yaml is scholarly, ...), so 16 public-internet tasks were refused as unknown. Fixed in 9f9cc25 with a test; task load now also checks the map against the checkout so a re-pin can't drift silently. The doc has the breakdown.

[Pwspang]

Do include how to execute the other 55 tasks or how to obtain the credentials for those services.

[zhenxi0901]

Done in 53607f3. Of the 55, 50 need a third-party account and 5 need k8s.

The 50 now run from a credentials directory: benchmark.toolathlon.credentials_dir points at a directory holding Toolathlon's filled configs/token_key_session.py and the key files it names (google_credentials.json, the GCP service-account key, the Snowflake key). The guide's new section "Running the account-backed tasks" says how to get the credentials — Toolathlon's own global_preparation/how2register_accounts.md walks through each account (about 30 min; two scripts automate most of it) — and what the adapter does with them: the checkout's copy stays at the example so the pinned tree remains verifiable; the directory is overlaid on the sandbox's configs/ after the project tree at preparation and again after the evaluate-time reinstall, so the grader uses the host's tokens and not what the agent left; task load reads each account server's file for the ${token.<field>} fields it substitutes and refuses the task naming the fields the directory does not provide (unset, still the example's "XX", or a key file missing), with the task's own token_key_session.py counting for the repositories/pages it names. Account-backed tasks join the concurrency-1 rule (one account, like one deployment), and the GitHub server's binary rides in the project archive for the tasks that need it. Eleven of the 50 also list web_search, so need harness.web_search like the public ones.

The 5 k8s tasks stay refused: their server wants a kind cluster on the Docker socket with host networking, which the sandbox will not get. Documented with the reason.

Checked against the real checkout with a GitHub task: no directory → refused naming the setting; the example's placeholders → refused naming huggingface_token; a dummy token → the task loaded, the overlay reached the sandbox, and preprocess failed closed on GitHub's 401 before any model call, no archive left on the host, the token in no log. I have no accounts registered for these services, so an end-to-end graded run is yours to try; the code path up to the service is exercised.

[Pwspang]

Is there a better method of loopback, instead of injecting a python file on task setup. Recommend to create a custom sandbox container for it

[zhenxi0901]

I kept it as an upload because the script goes in through the same step that carries Toolathlon's project tree into the container (Toolathlon's own runner copies files in at setup too), and it costs ~1 ms. A derived image would drop that one upload but add an image ARIES has to build, publish and re-pin whenever Toolathlon bumps its task image, and the runtime step is the same either way: with sleep infinity as the entrypoint something still has to start the forwarder before preprocess with the task's ports. There is no Docker-native way to make localhost:<port> inside a container reach the host, and rewriting Toolathlon's server configs to use network aliases would break the "configs used unmodified" rule. If you'd rather ARIES own the image, it's a small follow-up (Dockerfile under pkg/benchmark/toolathlon/, script pre-installed, same start step), we can discuss about this

[zhenxi0901]

Per Wei Siong (18 Sep): the uploaded forwarder stays as it is in this PR. The networking design is expected to change with the k8s integration (a reverse proxy), and the loopback path gets revisited then, together with the concurrency point above.

[Pwspang]

Do add the same functionality to openclaw too

[zhenxi0901]

Noted. The gateway is just an MCP endpoint and the benchmark side doesn't know which harness is on the other end, but OpenClaw has no MCP client in ARIES until #49 lands. With 9f9cc25 the entry is generated by wiring, so once #49 merges it's a few lines to hand it to OpenClaw. I'll do it as a follow-up, or fold it in here if #49 goes first , which order do you prefer?

[zhenxi0901]

Done in e731c76, without waiting for #49: OpenClaw takes remote MCP servers natively (mcp.servers.<name> with url and transport: sse | streamable-http, per-request timeout), so wiring hands it the same list Hermes gets under mcp_servers — the gateway first, then the profile's harness.mcp entries, now valid for either harness. One thing the first run showed: OpenClaw exposes configured servers as tools of its bundle-mcp plugin, and a sandboxed session (which ARIES always runs) sees plugin tools only if the sandbox gate names them — the servers loaded but the session had the 9 built-in tools. bundle-mcp is added to tools.sandbox.tools.alsoAllow whenever servers are rendered.

Verified with profiles/openclaw-toolathlon-canvas-list-test-deepseek.json on the pinned 2026.7.1 image: 88 tools in the session, 63 gateway calls (toolathlon__canvas-canvas_list_assignments and so on), graded; the verdict was the grader's row-count judgement, the same as on Hermes. The guide and docs/supported.md say both harnesses.

[chengzhi-lu]

Please update the MCP configuration description to match the latest implementation. Wiring now automatically registers the toolathlon gateway; users do not need to configure it under harness.mcp.servers. That block is optional, adds extra servers, and rejects the reserved name toolathlon.

[chengzhi-lu]

The evaluator entry point remains writable by the agent. restoreArtifacts() restores the task-local protected entries, but leaves /workspace/scripts/decoupled/container_eval.py and its dependencies untouched. An agent can replace this script with one that writes {"pass": true} to eval_res.json; this invocation then executes the modified script and records a successful score. VerifyRevision() only checks the host checkout.

Please protect the evaluator entry point and its execution dependencies from agent modifications, and add a regression test confirming that tampering with the evaluator cannot produce a passing result.

[zhenxi0901]

Fixed in 308726b. Before grading: (1) the pinned project tree is extracted again from the host checkout (revision re-verified), so container_eval and its imports are the host's; (2) the runtime the checkout does not carry — uv, its interpreter, .venv, uv's config files, the project's top-level files — is inventoried file by file (SHA-256, symlink targets) before the bridge exists and again before grading; any difference refuses the evaluation and names the paths; (3) the grader runs with PYTHONPYCACHEPREFIX on a private directory and PYTHONNOUSERSITE=1, so planted bytecode or a user-site .pth is not loaded.

Tests: a rewritten evaluator with its own {"pass": true} yields the real grader's fail; an altered venv file, a repointed interpreter symlink, a planted top-level file and a removed uv are each refused before the grader runs.

Not covered, stated in the guide: the image's system programs (shell, tar, find, sha256sum, libc). Root in the sandbox can replace those and a same-container grader cannot tell. Grading in a fresh container from the pinned image would close that and needs a Sandbox capability ARIES does not have; I can do it as a follow-up.

Cost: two hashes over ~1.5 GB (32k files) per task, about 7 s each on the VM. Checked against 140 recorded runs: none would have been refused — the agents' pip installs went to the system Python 3.10, not the grader's venv.

[zhenxi0901]

Correction to the last paragraph, and a follow-up fix in ec45f8b. The first 18 runs on 308726b's evaluation path (six tasks × 3, sampled for the resource attribution) found three defects:

1. The "none of the 140 runs would have been refused" claim was wrong for the two tasks that load the excel server: it writes .venv/lib/python3.12/excel-mcp.log while the agent works, and the inventory read that as tampering — 6 of the 18 evaluations refused. .log files are no longer inventoried.
2. The evaluate-time reinstall extracted the task directory too, overwriting the groundtruth_workspace/expected_results.json that a task's preprocess writes (seeded product IDs); woocommerce-update-cover graded 0 three times for it. The reinstall now carries the project code only; the task directory stays as the stash restored it. The flow test asserts the evaluation-time archive has no tasks/ member.
3. The shell inventory pipeline left the 1.5 GB it hashed in the page cache, which the sandbox cgroup is charged for when the host's cache is cold (2.4 GB peak against 0.6). It is now a small Python program on the image's system interpreter (never the venv it checks) that releases each file with posix_fadvise(DONTNEED).

Verified on the fixed binary: sales-accounting graded 1 (was refused), woocommerce-update-cover graded 1 (was 0); suite, race and lint green.

[chengzhi-lu]

All task occurrences forward to the same application host and fixed ports, so separate sandbox containers still share application state. With looping enabled and concurrency greater than one, two occurrences of canvas-list-test can overlap. Its preprocess deletes and recreates the configured courses, potentially removing courses while the earlier occurrence is using them.

Please isolate application state per occurrence or serialize access to a shared deployment across the entire prepare–agent–evaluate lifecycle. Serializing preparation alone would still allow a later task to reset an active task's state. Please also document this constraint and add coverage for overlapping occurrences.

[zhenxi0901]

Fixed in 308726b: task load refuses application-backed tasks when execution.concurrency > 1 and names them. At concurrency 1, looping included, occurrences are sequential, so prepare–agent–evaluate never overlap on the shared deployment. Tasks without an application run at any concurrency. Refusing rather than serializing keeps the concurrency setting meaning what it says; per-occurrence isolation would need one deployment per sandbox with its own ports, which the adapter does not manage. Documented; test covers 1 and >1 with and without application tasks.

[zhenxi0901]

Per Wei Siong (18 Sep): the concurrency-1 rule for application-backed (and now account-backed) tasks stays as it is in this PR. Per-occurrence application state is a networking question the k8s integration is expected to answer (a reverse proxy in front of the applications), so it will be raised there rather than solved here with an instance pool.

[chengzhi-lu]

“The grader trusts nothing the agent could write” is broader than the current implementation guarantees. The task bundle and protected task files are restored, but the evaluator entry point and shared Python dependencies remain in the agent-writable sandbox. Please align this paragraph with the evaluator protection implemented for the issue above and state precisely which code and inputs are trusted.

[zhenxi0901]

Rewritten in 308726b: the bullet lists what is trusted and how — inputs from the host bundle, grader and ground truth from the stash, evaluator code re-extracted from the verified checkout, runtime checked against the pre-harness inventory, bytecode and user site bypassed — and what is not (the image's system programs).

[chengzhi-lu]

Please clarify that benchmark.toolathlon.max_steps does not limit the Hermes agent loop. The implementation passes it to Toolathlon's preprocessing/bookkeeping, while Hermes controls agent execution independently. The current example can lead users to interpret max_steps: 200 as an enforced agent budget. Please document which settings actually bound agent execution.

[zhenxi0901]

Clarified in 308726b next to the example: max_steps is Toolathlon's max_steps_under_single_turn_mode, passed to preprocess for the bundle , bookkeeping for Toolathlon's own loop, which does not run here. The Hermes loop is bounded by Hermes's max_turns (rendered as 90) and the run's agent_timeout_seconds.

[zhenxi0901]

On the MCP configuration note: the guide and docs/supported.md have said this since 9f9cc25 (wiring registers the gateway; harness.mcp.servers is optional, for extra servers, and rejects the name toolathlon). The PR description still had the 11 Sep wording; updated now, with the evaluation and task-selection paragraphs for 308726b.

[zhenxi0901]

Rebased onto current main (9f070b9, the voice modes). Conflicts were in the wiring options literal, renderConfig's signature (now takes both the mode and the MCP servers) and the profile count; net change is otherwise the same as 879ae22. gofmt, lint, unit tests, race and build pass.
