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 | $0.00043 | $0.01251 |
| Opus 5 | $0.00022 | $0.00626 |
| Sonnet 5 | $0.00009 | $0.00250 |
| Haiku 4.5 | $0.00004 | $0.00125 |
Grade A, and why
release-harness 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 7d 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.

Release Harness Skill
Automates the claude-code-harness release process.
Quick Reference
- "Release a new harness version" ->
/release-harness - "Bump patch version" ->
/release-harness patch - "Create a minor release" ->
/release-harness minor
Execution Flow
Step 1: Change Verification
Run in parallel:
git status- Check uncommitted changesgit diff --stat- List changed filesgit log --format="%h|%s|%an|%ad" --date=short -10- Recent commit history (structured)
Git Log Flags (CC 2.1.30+)
Use structured log output for release note generation.
Commit List for Release Notes
# Structured format commit list
git log --format="%s" vPREV..HEAD
# Exclude merge commits (actual changes only)
git log --cherry-pick --no-merges --format="%s" vPREV..HEAD
# Detailed info (with author and date)
git log --format="%h|%s|%an|%ad" --date=short vPREV..HEAD
Key Use Cases
| Use Case | Flags | Effect |
|---|---|---|
| Release note generation | --format="%s" |
Extract commit messages only |
| Exclude merges | --cherry-pick --no-merges |
Actual commits only |
| Detailed list | --format="%h|%s|%an|%ad" |
Structured detailed info |
| Changed files | --raw |
Impact analysis |
Step 2: Version Determination
Check current version:
cat VERSION
Determine version based on changes (Semantic Versioning):
- patch (x.y.Z): Bug fixes, minor improvements
- minor (x.Y.0): New features (backward compatible)
- major (X.0.0): Breaking changes
Ask user: "What should the next version be? (e.g., 2.5.23)"
Step 3: CHANGELOG Update (JP + EN)
Important: Focus on user-facing changes. Keep internal fixes brief.
Update both CHANGELOG_ja.md and CHANGELOG.md.
CHANGELOG Rules
| Change Type | How to Document |
|---|---|
| User-facing impact | What's Changed + Before/After table |
| New feature | Added section, concise |
| Internal (CI/test/docs) | Internal section, one line |
| Bug fix (user-facing) | Fixed section |
| Bug fix (internal only) | Omit or merge into Internal |
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

release-harness is a skill published in the GitHub repository Chachamaru127/codex-harness (2 stars, last pushed 6mo ago), licensed MIT. It adds 43 tokens to every session and 1,251 once invoked, about $0.0002 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.
