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 | $0.00288 | $0.00288 |
| Opus 5.5 | $0.00115 | $0.00115 |
| Sonnet 5.5 | $0.00058 | $0.00058 |
| Haiku 4.5 | $0.00029 | $0.00029 |
Grade A, and why
harness-engineering-audit 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 2mo 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
AGENTS.md
This repo packages the harness-engineering-audit Codex skill.
Operating Map
- Source skill payload:
skills/harness-engineering-audit/ - Plugin mirror payload:
plugins/harness-engineering-audit/skills/harness-engineering-audit/ - Smoke test:
tests/smoke/run_skill_smoke.py - Mirror parity check:
tests/check_skill_mirror.py - User docs:
README.mdanddocs/ - Generated audit output:
.codex/reports/harness-engineering-audit/
Development Rules
- Keep the source skill and plugin mirror in sync.
- Do not add dependencies for validation or packaging unless explicitly requested.
- Keep audit mode report-only; setup modes must remain explicit and bounded.
- Keep user-scope and project-scope install examples distinct.
- Prefer small, reversible patches over broad rewrites.
Validation
Run before claiming completion:
make validate
make validate compiles Python scripts, checks plugin mirror parity, and runs the smoke suite.
Docs Authority
docs/README.mdis the docs index.docs/USAGE.mdis the user workflow reference.docs/INSTALL.mdis the install/update reference.docs/HARNESS_ENGINEERING_SOURCE_SYNTHESIS.mdrecords source concepts and synthesis.
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.
