changelog-writing

changelog-writing is a skill for Claude Code, Codex from androoAGI/starnet. It costs 43 tokens per session (1,213 once invoked), scanned A, original, MIT.

A plain-language record of what changed between two software versions. It groups changes by what users notice and identifies breaking changes, which are updates that require users to adjust how they use the software.

In plain words
What is it for?
Use it to compare two Git versions, describe user-visible changes, credit contributors, and put breaking changes with their fixes first.
Why use it?
It turns commit and pull-request history into information useful to people using the software. It also helps ensure changes in the selected version range are not missed.

About the project

StarNet is a local-first desktop harness for creating AI agents and arranging them in a pixel-art space station whose layout represents their capabilities, permissions, and workflow. It lets people run real model calls and tools through multiple bounded agents, using their own provider keys or accounts and optionally messaging the station through chat services. The catalogue entries are skills that extend or support work performed by StarNet agents.

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

changelog-writing 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 12d 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 — 41 lines — stays where its author put it; the contents beside it link to each section on GitHub.

A changelog tells the people who use the software what is different for them. It is not a list of what the developers did. The bar: every line is an effect a user can notice, every line traces to a change you read, and nothing in the range is unaccounted for.

Method

  1. Pick the road to the history. With a WORKBENCH, git runs through shell.exec; gh --version and gh auth status tell you whether the GitHub CLI can add pull request details. With no WORKBENCH, look for the connected GitHub account's tools (tool.search "github") and use the names it returns, never guessed ones. Neither: stop and tell the Commander to place a WORKBENCH or connect GitHub in ABILITIES.
  2. Pin the range. Both ends, as commits: git tag --sort=-creatordate to see the versions, git rev-parse <ref> to resolve each. "Since the last release" is a guess until you name the tag and the Commander's wording matches it. Write the range and both hashes into the file.
  3. List what is in it. git log --oneline --no-merges <from>..<to> and git log --oneline --merges <from>..<to>. Collect pull request numbers from the subjects, then gh pr view <number> --json title,body,author,labels for each. Count the commits and pull requests — you reconcile against that count in step 9.
  4. Read the change, not the subject. git show --stat <hash> and the diff of the files that matter (or gh pr diff <number>). The subject says what the author meant; the diff says what happened.
  5. Flag breaking changes first. Anything that makes a working setup stop working: a removed or renamed option, command or field, a changed default, a raised minimum version, a changed file or data format. Each one gets what breaks, who is affected, and the exact steps to move over. Unsure whether it breaks: ask the Commander; do not quietly leave it out.
  6. Group by what users notice. Added · Changed · Fixed · Removed · Security. Leave out internal churn: refactors with no change in behaviour, test-only and CI changes, formatting, dependency bumps with no user effect, merge commits, and a change plus its revert inside the same range.
  7. Rewrite each as one plain sentence about the effect. "Exports no longer drop the last row when the file has no final line break (#412)." — not "fix off-by-one in csv writer". No function or file names, and never a pasted commit subject. End with the pull request or issue number.
  8. Credit contributors. git shortlog -sn --no-merges <from>..<to> plus the pull request authors and any co-author lines. Use the name or handle each person uses on the project. Never build a handle from an email address.
  9. Reconcile. Every commit and pull request from step 3 is either behind an entry or on a left-out list with its reason. Every Fixed line points at a diff that shows the fix.
  10. Write the file. If the project keeps a changelog, fs.read it and match its headings, order and tense; add your section at the top with fs.edit and leave earlier entries untouched. Otherwise fs.write CHANGELOG-<version>.md: a ## <version> — <date> heading, then Breaking changes, Added, Changed, Fixed, Removed, Security, Contributors, with empty sections left out. Re-read it and name it with deliverable_note.

Changes

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.
