What it does
Changelog is an agent skill from aviatesk/JET.jl. Invoke before committing user-facing JET changes such as features, bug fixes, compatibility changes, or deprecations. Skip internal refactors, CI or docs-only changes, and routine dependency bumps without user impact.
Its SKILL.md is about 490 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, Debugging and Refactoring. The repository describes itself as: A code analyzer for Julia. No need for additional type annotations. The licence is MIT.
When your agent uses it

- Tasks that involve Debugging
- Tasks that involve Refactoring
Example prompts
- “/changelog”
What it can do on your machine
Read from SKILL.md and the folder at commit db83fa7. 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
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
Links to these hosts (documentation or services it may open):
keepachangelog.com
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
Changelog loads about 492 tokens when it runs. Until then it costs about 57 tokens; SKILL.md has 221 words of instructions outside code blocks.
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.
SKILL.md
The full file from aviatesk/JET.jl at commit db83fa7, republished under its MIT licence (© aviatesk). 221 words, ~492 tokens.

Updating CHANGELOG.md
Format
This project follows Keep a Changelog.
Section structure
Add new entries under ## [Unreleased]. Do not edit a released section unless
the user explicitly requests it.
Use the established Keep a Changelog subsections as appropriate:
### Addedfor new functionality### Changedfor changes to existing functionality or compatibility### Deprecatedfor features that will be removed### Removedfor removed functionality### Fixedfor bug fixes
Use ### Internal only when maintainers intentionally want to record a notable
internal change. Do not add empty subsections or introduce a new category when
an existing one fits.
Entry style
- Start Added entries with "Added ..." and Fixed entries with "Fixed ...".
- Describe Changed entries in terms of concrete behavior or compatibility.
- Refer to GitHub issues as
aviatesk/JET.jl#NNN. - Use backticks for report types, function names, configuration names, and other code elements.
- Record dependency changes when they affect supported Julia versions, compatibility, installation, or user-visible behavior. Omit routine bumps.
Entry content
Write entries from the user's perspective. Describe what changed in terms of user-visible behavior, not implementation details.
- Do not include lowered IR details, Compiler.jl hook methods, abstract interpretation state, or virtual-process internals unless users can reasonably observe or interact with them.
- The "why" of a fix rarely matters to users; the "what" does. If the prior behavior is worth mentioning, describe its user-visible symptom rather than its internal cause.

Questions about Changelog
What does Changelog do?
Invoke before committing user-facing JET changes such as features, bug fixes, compatibility changes, or deprecations. jl. Invoke before committing user-facing JET changes such as features, bug fixes, compatibility changes, or deprecations.
When should I use Changelog?
Changelog fits situations like: tasks that involve Changelog and release notes; tasks that involve Debugging; tasks that involve Refactoring.
How do I install Changelog in Claude Code?
Run `npx skills add aviatesk/JET.jl --skill changelog -a claude-code`. Or copy the skill folder (.agents/skills/changelog in aviatesk/JET.jl) into .claude/skills/changelog in your project. Claude Code loads it when a task matches its description.
How do I install Changelog in Codex?
Run `npx skills add aviatesk/JET.jl --skill changelog -a codex`. Or copy the skill folder (.agents/skills/changelog in aviatesk/JET.jl) into .agents/skills/changelog in your project. Codex loads it when a task matches its description.
Can I use Changelog in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add aviatesk/JET.jl --skill changelog -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/changelog, .gemini/skills/changelog, .github/skills/changelog and .opencode/skills/changelog in your project.
What does Changelog need to run?
SKILL.md names no scripts, command-line tools or credentials: Changelog is instructions for the agent only.
Does Changelog access the network?
SKILL.md names 1 domain. As links in the text: keepachangelog.com. This is read from the text; nothing was executed.
Is Changelog safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Changelog use?
Changelog is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Changelog use?
About 492 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Changelog?
Skills that share tags, products or a category with Changelog: Changelog (aviatesk/JETLS.jl, 314 stars), Release Digest (Kiln-AI/Kiln, 5.2k stars), Superplane Changelog (superplanehq/superplane, 7.7k stars) and Code Review Graph Navigator (handsontable/handsontable, 22k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Changelog?
aviatesk (a GitHub user) maintains it in aviatesk/JET.jl, which has 883 GitHub stars. The repository holds 4 skills in this directory. The repository was last updated on October 7, 2026.
