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 | $0.00318 | $0.00318 |
| Opus 5.5 | $0.00127 | $0.00127 |
| Sonnet 5.5 | $0.00064 | $0.00064 |
| Haiku 4.5 | $0.00032 | $0.00032 |
Grade A, and why
vibe-harness 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.

Project Goal
Vibe Harness turns a human project plan into a lightweight agent-ready repository harness for sustainable AI coding.
Working Rules
- Keep the skill body concise; move deeper guidance to
skills/vibe-harness/references/. - Keep templates generic, small, and easy to adapt.
- Do not add heavyweight governance artifacts unless they solve a clear continuity or verification problem.
- Prefer concrete paths, commands, and evidence over broad agent philosophy.
- Do not make unverified adoption, benchmark, or compatibility claims.
Validation
Run before finishing changes:
python3 scripts/validate.py
python3 scripts/audit.py examples/expected-harness
If validation cannot run, explain why and record the likely impact.
Release Shape
The repo should stay installable as a skill package and understandable as an open-source project. README is for users; skills/vibe-harness/SKILL.md is for agents; docs/launch-playbook.md is for maintainers preparing public launch.
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.
