Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00024 | $0.00237 |
| Opus 5 | $0.00012 | $0.00118 |
| Sonnet 5 | $0.00005 | $0.00047 |
| Haiku 4.5 | $0.00002 | $0.00024 |
Grade A, and why
codex-check 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 9d 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
Check Work
Verify the current task without turning the main session into a diagnostic dump.
-
Identify changed files:
git status --short git diff --name-only -
Load check context:
python3 scripts/codex_harness.py task agent-context <task> check -
Run task-specific tests and focused syntax checks.
-
For harness changes, run:
python3 install.py -
Use deeper diagnostics only when the focused check fails:
python3 scripts/codex_harness.py context --dashboard python3 ~/.codex/harness/bin/verify_all_codex_harness.py --deep python3 ~/.codex/harness/bin/verify_all_codex_harness.py --state-audit
Report product/task outcome first. Mention harness internals only if they block the requested work or explain a failed verification.
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.

codex-check is a skill published in the GitHub repository yinanli1917-cloud/searching-apple-notes (2 stars, last pushed 1mo ago), licensed MIT. It adds 24 tokens to every session and 237 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
