tutor-mcp: Instructions file for Codex

AGENTS.md

tutor-mcp AGENTS.md is an instructions file for Codex, OpenCode from ArnaudGuiovanna/tutor-mcp. It costs 453 tokens per session, scanned A, original, MIT.

Repository instructions for a project that require completed changes to be committed and published through staging before being fast-forwarded to main. A fast-forward merge updates the target branch without creating a separate merge commit.

In plain words
What is it for?
It is for preparing exact files, running the project's finish checks, committing changes, pushing staging, and publishing to main.
Why use it?
It gives the coding agent a defined Git workflow and helps prevent accidental inclusion of unrelated files or unsafe history changes.

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

tutor-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 2d 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.

What it actually says

Repository workflow

The maintainer requests publication at the end of every completed implementation task: commit/push to staging, then fast-forward merge/push to main.

  • Work on staging. Before starting with a clean tracked worktree, fetch origin and reconcile staging with main by fast-forward only. Stop on divergence; never force-push, discard changes, or manufacture a merge resolution.
  • For a completed change, review the diff and identify the exact task-owned files. Preserve unrelated edits, untracked notes and credentials. Do not use git add . or git add -A to prepare a publication.
  • Run python3 scripts/finish_task.py prepare --message "type: description" -- path/to/file ..., with actual explicit file paths (not directories). This records the exact staged tree and the current Codex session when available.
  • Run python3 scripts/finish_task.py publish before the final response. It runs the verification script, commits on staging, pushes staging, fast-forwards main, pushes main, checks the remote heads and returns to staging. Request normal execution approval if Git/network/test permissions require it.
  • The Codex Stop hook is a fallback for an explicitly prepared task in the same session, not permission to publish every dirty file on every turn.
  • Read-only tasks, incomplete work, questions and explicit "do not publish" requests must not prepare a task. A later user opt-out overrides this default; cancel a pending intent with python3 scripts/finish_task.py cancel (the index is left intact). Report blockers instead of bypassing checks or hook trust.
  • After a failed publication, inspect its state and use publish to resume the same commit. Do not create a replacement commit just because a push failed.
  • Report the commit and the observed remote/CI state. Publication is not a deployment, and local verification is not a claim that GitHub CI has passed.

See task publication for setup and recovery.

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.
