Getting it into your agent
This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

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 | $0.00028 | $0.00130 |
| Opus 5 | $0.00014 | $0.00065 |
| Sonnet 5 | $0.00006 | $0.00026 |
| Haiku 4.5 | $0.00003 | $0.00013 |
Grade A, and why
harness-evolve scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
evolve 스킬을 호출한다 (/oh-my-harness:evolve).
반영이 끝나면 반드시 검증으로 닫는다:
python3 "${CLAUDE_PLUGIN_ROOT}/scripts/harness_lint.py" .
진화는 파일을 고치는 일이므로, 고친 뒤 계약이 깨졌는지 확인하지 않으면 «개선했다» 는 주장이 근거 없는 말이 된다.
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.

harness-evolve is a command published in the GitHub repository IISweetHeartII/oh-my-harness (1 stars, last pushed 14d ago), licensed Apache-2.0. It adds 28 tokens to every session and 130 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.
