From 70e7bbd222f2ebdc5774e0b06c72b052a0e692c2 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Aur=C3=A9lien=20Sibiril?= <81782+aureliensibiril@users.noreply.github.com> Date: Thu, 2 Apr 2026 17:04:44 +0200 Subject: [PATCH 01/37] Wire vendor assessment and LLM file parts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Introduce the initial vendor assessor plumbing in the service layer (pkg/probo/vendor_service.go, service.go), bootstrap (builder, probod, llm_config), root CLI wiring and the assessVendor GraphQL mutation resolver. Teach the LLM provider layer to carry file parts (PDF, CSV) so downstream vetting sub-agents can hand documents to the model instead of raw text. Both Anthropic and OpenAI providers learn the new part shape through pkg/llm/{part,message,chat}.go and their respective provider adapters.

Agent framework additions: - ResultJSON, ResultError, ResultErrorf result helpers - TypedTool[In, Out] with auto-marshaled output - Toolset interface with CollectTools and MergeToolsets - WithToolsets option for declarative tool assembly Tool packages (pkg/agent/tools/): - browser: navigate, extract, click, PDF, sitemap, robots - security: SSL, headers, DMARC, SPF, DNSSEC, CSP, CORS, WHOIS, DNS records, HIBP breach check - search: web search, government DB, Wayback, document diff - internal/netcheck: SSRF protection for all tools Orchestrator with 16 specialized sub-agents for crawling, security assessment, compliance, market presence, data processing, AI risk, and more.

Once the budget is exhausted the sub-agent returns malformed or empty JSON and the orchestrator has to work around the hole. When the agent has both tools and a structured output request, the loop now runs in exploration mode with no schema enforcement and no tool_choice override. Once the model signals finish_reason stop, the loop promotes the next iteration into a synthesis turn: the exploration message is kept in history (dropped if empty), a user nudge is appended, tool_choice is forced to none, and the schema is enforced. The model converts what it has gathered into JSON in one shot without any scratchpad fight. Agents without tools or without a structured output request are untouched. The empty-output retry path is preserved as a safety net for the synthesis turn itself.

The research browser in the vendor assessment is intentionally allowed to roam the public web, but it must still refuse URLs that resolve to loopback, private, or link-local IPs. - ClickElementTool reads the post-click location and feeds it back through Browser.checkURL. A click that triggers navigation to a different host (JS-initiated redirect, malicious , vendor page hijack) used to extract text from whatever page the browser ended up on; that path could bypass the initial checkURL call and read internal endpoints. The post-click revalidation closes that gap.

Match the sitemap handling and read the path off the original-case raw line. - extract_page_text pulled the full document.body.innerText over the DevTools protocol before truncating on the Go side, so a huge page could burn bandwidth and memory well beyond maxTextLength. Slice the string in JS at 4x maxTextLength code units first (safe upper bound for UTF-16 code units per Go rune) before transferring, then finish the rune-exact truncation in Go. - diff_documents silently dropped the "documents too large for detailed diff" message when either side exceeded the 5000-line LCS cap, returning HasDifferences=false and an empty UnifiedDiff. Add a tooLarge flag on the internal diffOutput and surface the message via ErrorDetail so the caller can distinguish "no differences" from "too large to compare".

Observed on a Pylon assessment where the orchestrator consumed ~19 minutes of sub-agent work and the extractor then failed immediately with "context deadline exceeded" — losing the full markdown report that had just been produced. Detach the extractor from the assessment context and give it a dedicated 5-minute budget via context.WithoutCancel + a fresh WithTimeout. The extractor has no tools and emits a single structured JSON output, so five minutes is more than enough even when Anthropic forces the streaming path.
