fermi-mcp: Instructions file for Codex

AGENTS.md

fermi-mcp AGENTS.md is an instructions file for Codex, OpenCode from abel30567/fermi-mcp. It costs 943 tokens per session, scanned A, original, MIT.

A set of project instructions for coding agents working on the fermi-mcp repository. It describes separate workers for building, checking, fixing, and assessing changes, coordinated through pull requests and isolated Git workspaces.

In plain words
What is it for?
It is for organizing multi-agent development, assigning repository tasks, running independent verification, and controlling which agent may merge changes.
Why use it?
It gives agents clear responsibilities and review steps, reducing the chance that one worker merges unverified code.

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

fermi-mcp AGENTS.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 yesterday.

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.

Agent rules

Development pattern: orchestrator + independent workers

Work is done by headless agent workers, one task each, in isolated git worktrees, coordinated through pull request comments. Nothing merges until an independent verifier has signed off on the exact head commit. Tooling: .agents/orchestrator/ (orch help).

Roles

Role Runs as Does
Orchestrator you + your interactive agent session Triages tasks, gathers inputs workers cannot reach, launches workers, runs the merge gate, releases. The only role that merges.
Builder orch launch builder KEY slug "TASK" Own worktree and branch. Builds, runs every gate, opens the PR, posts [BUILDER] READY, exits.
Verifier orch launch verifier PR "criteria" Fresh detached worktree. Adversarial: re-runs the gates itself and tries to break every criterion. Never pushes.
Fixer orch launch fixer PR "focus" Addresses every finding, merges the base, posts [BUILDER] ADDRESSED.
Blast radius orch launch br PR "focus" Only for risky PRs (orch risk PR). Proves by running code what the change cannot break outside its diff.

PR comment markers (only a comment's FIRST line counts)

Marker By Content
[BUILDER] READY builder head SHA, gate table, evidence (command → result) per acceptance criterion
[VERIFIER] CHANGES REQUESTED verifier Reviewed head <sha>, findings F1..Fn: criterion, evidence, repro command
[BUILDER] ADDRESSED fixer per finding: fix + commit SHA, or a reasoned rebuttal
[VERIFIER] VERIFIED verifier Reviewed head <sha>, evidence table for every criterion
[BLAST-RADIUS] SAFE / UNSAFE blast radius Reviewed head <sha>, the one fact that makes it safe and the command that proved it
[BUILDER] BLOCKED builder/fixer Missing / What was tried / Resume from (branch @ sha)
[ORCHESTRATOR] … orchestrator binding rulings, merge notes

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.
