agent-collab CLAUDE.md

Project-specific instructions for agent-collab, a tool that runs Codex and Cursor as background coding workers inside Claude Code.

In plain words
What is it for?
Use it when delegating code analysis, architecture checks, security reviews, refactors, implementation work, or pre-merge reviews in that project.
Why use it?
It gives agents shared guidance about which worker and model to use for different tasks, including deeper analysis and faster implementation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

agent-collab CLAUDE.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Claude-specific notes on top of the shared agent guide:

  • Model delegation (repo-specific working preferences, not plugin defaults):
    • Deep code analysis, architecture validation, security review, and high-stakes refactors → Codex task/rescue with --profile deep (resolves to --model gpt-5.6-sol --effort xhigh); escalate to --profile deep --effort max when a verdict still feels shallow.
    • Fast iteration, everyday implementation, scaffolding, and the standing pre-merge reviews → Cursor with --model cursor-grok-4.5-high-fast.
    • Escalation rule: when a task that started on the Cursor model turns out to need deep analysis or security judgement, hand it to Codex --profile deep rather than pushing the faster model further.
    • Both model ids and the max effort tier were live-verified against the real CLIs on 2026-08-05 (codex-cli 0.146.0); re-verify before assuming newer names. The deep/fast profile table (plugins/codex/scripts/ codex-companion.mjs) is grounded in these same ids.
  • Key references (read on demand, not imported): README.md for the user-facing docs, plugins/*/CHANGELOG.md for history, tests/chassis-drift.test.mjs for the current divergence pins.
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
