Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00083 | $0.00859 |
| Opus 5.5 | $0.00033 | $0.00344 |
| Sonnet 5.5 | $0.00017 | $0.00172 |
| Haiku 4.5 | $0.00008 | $0.00086 |
Grade A, and why
close 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 27d 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.
How it starts
The opening of the file, as written. The whole thing — 88 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Skill Provenance: Close
Update all version-tracking artifacts when finishing a skill editing session. This ensures the bundle leaves the session in a consistent, verifiable state.
When to use
Run /skill-provenance:close after you've finished editing files in a skill
bundle and before committing, packaging, or handing off.
Protocol
-
Validate before mutation. Run verify-only
validate.shfirst when available. Resolve structural grammar, unsafe or duplicate paths, symlink components, missing files, and unlisted files before updating hashes. Add a manifest entry for each new file;--updatenever adds unlisted files. Hash mismatches and missing or malformed hashes may then be repaired with an explicitvalidate.sh --updateworkflow;hash: nullremains an intentional opt-out. -
Update internal version headers. For each changed file that carries YAML frontmatter with version metadata:
- Increment
versionby 1. - Set
version_dateto today. - Set
previous_versionto the old version number. - Write a
change_summary(1-3 sentences describing what changed, not just that something changed).
- Increment
-
Update MANIFEST.yaml. For every changed versioned file:
- Update
versionto match the new internal version. - Recompute and update
hash. - For files that don't carry internal headers (JSON, scripts, binaries),
the manifest
versionfield is authoritative — increment it there. - Bump
bundle_version(semver): PATCH for fixes/docs, MINOR for new features, MAJOR for breaking changes. - Update
bundle_dateto today. - If the user deployed or reinstalled the skill this session, update
relevant
deploymentsmetadata.
- Update
-
Update CHANGELOG.md. Add a new entry at the top:
- Use the new
bundle_versionand today's date as the heading. - Name every file that changed and what changed in it.
- Flag staleness explicitly. If a versioned file was changed but a dependent file was not updated (e.g., SKILL.md changed but evals.json wasn't updated to match), say so in the entry.
- Use the new
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.

close is a skill published in the GitHub repository snapsynapse/skill-provenance (7 stars, last pushed 28d ago), licensed MIT. It adds 83 tokens to every session and 859 once invoked, about $0.0003 per session on Opus 5.5. 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.
Other skills, from other repositories
ship
Enter the Ship phase of CocoBrew. Reads review.md approval, generates structured commit, creates semantic version tag, optionally creates PR via gh CLI, and records deployment details. Requires approved review.
forgejo-cli
Use when managing a Forgejo or Gitea server from the terminal: issues, pull requests, repositories, file contents, labels, milestones, releases, webhooks, user settings, or any /api/v1 endpoint through a safe generic API command. Do not use this skill for unrelated requests; route to the nearest named specialist.
release-engineering
Design, automate, and operate end-to-end software releases: release process models and pipelines (trunk-based development, CD stages, release trains), progressive delivery and feature flags, versioning and artifact management (SemVer, conventional commits, changelogs, SBOM/provenance), readiness and quality gates…
verified-delivery
Implement and deliver an authorized change end to end — verify, open the PR, merge, and confirm post-merge state — using live-state gates, durable interruption handoffs, and live-state-first resumption. Use when a user grants end-to-end delivery authority for a specific change and the work may cross tool-call limits…
breaking-changes
Detects breaking changes between two git refs and generates a migration guide.
release-notes
Generates release notes from commits since the last tag.
