sk-create-changelog

sk-create-changelog is a skill for Claude Code, OpenCode from MichelKerkmeester/skilled-agent-harness_spec-driven-loops. It costs 23 tokens per session (6,457 once invoked), scanned A, original, MIT.

A workflow for writing release notes that describe changes to a component or to a specific documentation packet.

In plain words
What is it for?
Use it to create global or packet-specific changelogs and calculate the next version when global versioning applies.
Why use it?
It determines where the changelog belongs, how it should be versioned, and whether it follows the expected format.

Skill for Claude CodeOpenCode

Written for Claude Code and OpenCode: allowed-tools in frontmatter, but also installed under .opencode/. Also seen: mentions OpenCode.

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is node .opencode/skills/system-spec-kit/runtime/cli/dist/spec-folder/nested-changelog.js <spec-folder> --write.

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.

Token cost

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.

Security

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:

  1. Creating a global component changelog for .opencode/changelog/{component}/v{VERSION}.md.
  2. Creating a packet-local nested changelog for a spec folder or phase child.
  3. Running or supporting /create:changelog.
  4. Resolving a changed spec folder, component hint, or recent git history into a changelog target.
  5. Calculating the next four-part semantic version for a global changelog.
  6. 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:

  1. The user only wants a generic release plan with no file output.
  2. The target is a README or install guide. Use create-readme.
  3. 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, or create-skill.
  4. The user wants to audit, validate, score, or optimize an existing changelog. Use create-quality-control.
  5. The work source is too ambiguous to resolve to a spec folder, component hint, or recent git history.
  6. 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.
