What it does

Write Changelog is an agent skill from eslint-config/airbnb-extended. Write the next CHANGELOG.md section from the commits and diffs since the last release. Use before opening a release PR, or when asked to "write the changelog" or "prepare release notes".

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Changelog and release notes. It works with ESLint and TypeScript. The repository describes itself as: A powerful ESLint configuration extending the popular Airbnb style guide, with added support for TypeScript. The licence is MIT.

When your agent uses it

  • Tasks that involve Changelog and release notes

Example prompts

  • “write the changelog”
  • “prepare release notes”
  • “/write-changelog”

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Find the range
  2. Read what changed
  3. Sort the changes
  4. Write the lines
  5. Insert it
  6. Finish

What it can do on your machine

Read from SKILL.md and the folder at commit e855b33. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • git
    • pnpm

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use git and pnpm, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Write Changelog loads about 1k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 405 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~51
When it runs · the whole SKILL.md, loaded when a task matches
~1k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Write the next CHANGELOG.md section from the commits and diffs since the last release. Use before opening a release PR, or when asked to "write the changelog" or "prepare release notes".

Write the changelog

The release workflow copies the matching ## x.y.z section of CHANGELOG.md into the GitHub Release. Write it by hand, in the project's format, before the release PR is merged.

1. Find the range

  • Version: read it from packages/eslint-config-airbnb-extended/package.json. If it was not bumped yet, ask the user which version to use.
  • Last release: the first ## x.y.z heading below the top of CHANGELOG.md.
  • Last tag: use V<x.y.z> if it exists. Otherwise use eslint-config-airbnb-extended@<x.y.z>. Check with git tag --sort=-creatordate.
  • Date: today, as YYYY-MM-DD.

2. Read what changed

bash
git log --no-merges --format='%h %an %s' <last-tag>..HEAD
git diff --stat <last-tag>..HEAD -- . ':!pnpm-lock.yaml'

Read the real diffs for rules/, configs/, extensions/, helpers/, index.ts, packages/create-airbnb-x-config/, and apps/build-templates/lib/. Do not guess from commit titles.

Skip noise: merge commits, formatting, lockfile only changes, internal CI and AI tooling files.

3. Sort the changes

HeadingPut here
### 🚨 Breaking ChangesA rule turned on as error. A rule changed to a stricter value. Removed or renamed public exports. Dropped Node/ESLint versions. A new CLI flag value that changes defaults.
### 🚀 FeaturesNew rules that are warn or off. New helpers, options, CLI flags, supported plugins or runtimes, docs features.
### 🩹 FixesBug fixes, dependency updates, docs fixes, internal improvements users may notice.
### ❤️ Thank YouOutside contributors only, as - Name @github-username. Never list the maintainer. Skip the section if there are none.

Leave out any heading that has no items. Keep the order above.

Legacy config values never change (see CLAUDE.md), so a legacy change is always a bug fix or breaking change. Flag it to the user.

Show full SKILL.md (161 more words)Show less

4. Write the lines

  • One line per change, starting with - .
  • Prefix a line with **<package-name>:** when it touches one package, for example **eslint-config-airbnb-extended:** or **create-airbnb-x-config:**. No prefix when it covers the whole repo.
  • Name rules in backticks with their full id, for example n/prefer-import/assert-strict, and state the severity, for example "with error severity".
  • For a breaking change, say what users must do.
  • Reference issues as #123. Find them in commit messages and PR titles.
  • Plain, simple English. Short sentences. No marketing words.

5. Insert it

Add the new section at the top of CHANGELOG.md, above the previous version, with a blank line between sections:

md
## 3.3.0 (2026-10-03)

### 🚨 Breaking Changes

- **eslint-config-airbnb-extended:** Introduced the `n/prefer-import/assert-strict` rule with `error` severity, `node:assert` must now be replaced by `node:assert/strict`

Do not add --- or a "Full Changelog" link. The release workflow adds them.

6. Finish

  • Run pnpm format so the file passes Prettier.
  • Show the new section to the user and point out anything you were unsure about, such as a guessed severity, a missing contributor, or a possible breaking change.
  • Do not commit, tag, or publish.
