clawtfup: Instructions file for Codex

AGENTS.md

clawtfup AGENTS.md is an instructions file for Codex, OpenCode from egedursun/clawtfup. It costs 969 tokens per session, scanned A, original, MIT.

Required rules for clawtfup, a tool that checks code changes against security and project policies. The check is a mandatory gate before work is considered finished or ready for review.

In plain words
What is it for?
It is for running the evaluator from the repository root, reading its report, and resolving missing tools or environment problems before completing a task.
Why use it?
It prevents agents from declaring changes safe without running the project's policy evaluation and makes denied or error-level findings visible.

Written for Codex and OpenCode: the file is AGENTS.md.

This is egedursun/clawtfup's own configuration. It tells Codex and OpenCode how to work on clawtfup itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything clawtfup configures →

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

clawtfup 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 1mo 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.

Agent rules: policy evaluation is mandatory

You are working in a repo that uses clawtfup (OPA + .clawtfup/). Treat this as a hard gate, not optional hygiene.

Required behavior

  1. Before you treat a coding task as finished, a batch of edits as safe to ship, or a change as “ready for review”, run the evaluator from the repository root (or pass --workspace to that root):

    clawtfup evaluate --pretty
    

    If clawtfup is not on PATH, use the project venv and module form:

    python -m policy_eval evaluate --pretty
    

    The CLI is strict by default: exit code 2 if allow is false or there are error-severity findings (the JSON report is still printed on stdout). You do not pass a flag to “turn strict on”—that is already the behavior.

  2. You do not skip this because the diff is “small”, “only docs”, or “obviously fine”. If the command is missing or fails to run, fix the environment (e.g. pip install -e ., OPA on PATH or tools/opa) and re-run—do not silently continue.

  3. Only use --no-strict when a human explicitly asked for a non-failing exit while inspecting a denied report (e.g. scripting that parses JSON regardless). Agents must not use --no-strict to avoid fixing policy violations.

  4. If evaluation fails (non-zero exit), read findings[] and each item’s feedback.remediation (when present). Implement fixes that satisfy policy, then run the command again until exit 0—or stop and say clearly that policy blocks the change and why.

  5. Default semantics: the evaluator indexes the working tree on disk (no git diff HEAD for the default full scan), applies .cfupignore patterns when that file exists (gitignore syntax), then runs policy on the entire indexed tree by default (inputs.scan_mode: full_tree). Pass --diff-file or stdin to layer a unified diff on top of the disk index. Use --diff-only without --diff-file only when you intentionally scope to git diff HEAD (legacy). Agents must not use --diff-only to evade fixes unless the user asked.

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.
