Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 | $0.00023 | $0.06457 |
| Opus 5 | $0.00012 | $0.03229 |
| Sonnet 5 | $0.00005 | $0.01291 |
| Haiku 4.5 | $0.00002 | $0.00646 |
Grade A, and why
sk-create-changelog 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 6d 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 — 604 lines — stays where its author put it; the contents beside it link to each section on GitHub.
create-changelog
create-changelog is the changelog-authoring workflow packet of the sk-doc family. It creates global component changelog files under .opencode/changelog/{component}/v{VERSION}.md or packet-local nested changelogs under a spec packet's changelog/ folder, depending on source topology.
The executable contract lives here: resolve the work source, detect global vs packet-local output, calculate the version when global versioning applies, generate content from the canonical format, validate, then write the file. Use assets/changelog-template.md as the shared global changelog template and the references/ set (routed by references/README.md) only for supplementary worked examples or edge cases.
1. WHEN TO USE
Activation Triggers
Use this workflow when the task involves:
- Creating a global component changelog for
.opencode/changelog/{component}/v{VERSION}.md. - Creating a packet-local nested changelog for a spec folder or phase child.
- Running or supporting
/create:changelog. - Resolving a changed spec folder, component hint, or recent git history into a changelog target.
- Calculating the next four-part semantic version for a global changelog.
- Preparing GitHub release notes from the generated global changelog content.
Keyword triggers: create changelog, /create:changelog, changelog, changelog entry, release notes, global changelog, packet-local changelog, nested changelog, since the last version, --bump, --release, vX.Y.Z.B.
When NOT to Use
Use another sk-doc packet when:
- The user only wants a generic release plan with no file output.
- The target is a README or install guide. Use
create-readme. - The target is an agent, command, benchmark package, flowchart, feature catalog, manual testing playbook, or skill. Use
create-agent,create-command,create-benchmark,create-flowchart,create-feature-catalog,create-manual-testing-playbook, orcreate-skill. - The user wants to audit, validate, score, or optimize an existing changelog. Use
create-quality-control. - The work source is too ambiguous to resolve to a spec folder, component hint, or recent git history.
- The user asks for Git branch, commit, PR, or release mechanics beyond preparing release-note content.

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.

sk-create-changelog is a skill published in the GitHub repository MichelKerkmeester/skilled-agent-harness_spec-driven-loops (35 stars, last pushed yesterday), licensed MIT. It adds 23 tokens to every session and 6,457 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 2026-09-03.
