Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add instructions/nvfp4/codex-scrub/agents-mdgit clone --depth 1 https://github.com/NVFP4/codex-scrubWhat 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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00134 | $0.00134 |
| Opus 5 | $0.00067 | $0.00067 |
| Sonnet 5 | $0.00027 | $0.00027 |
| Haiku 4.5 | $0.00013 | $0.00013 |
Grade A, and why
codex-scrub 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.
What it actually says
AGENTS.md
This is a Python TUI tool to scrub Codex threads from the disk.
Commands
This project uses uv, ruff for linting and ty for type checker.
uv syncto setup dependenciesuv run ruff format .to formatuv run ruff format --check .to check formatting.uv run ty checkto check types.
Code Guidelines
- PREFER simple, elegant, and readable Pythonic code.
- NEVER add pydantic or do any crazy type gymnastics.
- PREFER to keep files within 500+ LoC.
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.
