What it does

Changelog is an agent skill from bholmesdev/hubble.md. Add a user-facing entry to CHANGELOG.md for work that just landed. Use when wrapping up a feature/fix, or when asked to record what changed. Called standalone or from the done skill.

Its SKILL.md is about 560 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. The repository describes itself as: The best notepad for you and your agents. The licence is MIT.

When your agent uses it

Example prompts

“/changelog”

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

Open root CHANGELOG.md.
Add one bullet under ## [Unreleased], in the right subhead
Write it for a user reading release notes, not as a commit message
Link the PR for every entry (not the issue).
Credit the contributor. Every entry from someone other than bholmesdev

What it can do on your machine

Read from SKILL.md and the folder at commit 571a523. 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:
- gh
From the folder's file list and the shell code blocks in SKILL.md.
Network
Hosts in commands or code, which the agent is likely to contact:
- github.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 564 tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 223 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~49
When it runs · the whole SKILL.md, loaded when a task matches: ~564

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 bholmesdev/hubble.md at commit 571a523, republished under its MIT licence (© bholmesdev). 223 words, ~564 tokens.

name: changelog
description: Add a user-facing entry to CHANGELOG.md for work that just landed. Use when wrapping up a feature/fix, or when asked to record what changed. Called standalone or from the `done` skill.

Changelog

Record what shipped as it lands. Do not scrape commits at release time, write the entry now while the change is fresh.

How

Open root CHANGELOG.md.
Add one bullet under ## [Unreleased], in the right subhead:
- Added — new features the user can see/use.
- Changed — behavior changes to existing features.
- Fixed — bug fixes.
Write it for a user reading release notes, not as a commit message:
- One line, present tense.
- Describe the effect, not the implementation or file paths.
- Skip internal-only churn (refactors, deps, CI, tests) unless it changes what the user experiences.
Link the PR for every entry (not the issue).
Credit the contributor. Every entry from someone other than bholmesdev gets a thank you, including when you are that contributor writing your own entry.

Find the handle:
- PR already open: gh pr view --json author --jq .author.login.
- No PR yet: gh api user --jq .login, the account that will open it.
Then, unless the handle is bholmesdev, put one of these before the link:
- Thanks [@handle](https://github.com/handle)! for their own work.
- Thanks [@handle](https://github.com/handle) for the suggestion! when bholmesdev landed someone else's issue.

Create a subhead only if it has at least one entry. Leave the empty scaffold subheads as-is for the next entry.

Questions about Changelog

What does Changelog do?

Add a user-facing entry to CHANGELOG.md for work that just landed. md.md for work that just landed.

When should I use Changelog?

Changelog fits situations like: wrapping up a feature/fix; asked to record what changed.

How do I install Changelog in Claude Code?

Run `npx skills add bholmesdev/hubble.md --skill changelog -a claude-code`. Or copy the skill folder (.agents/skills/changelog in bholmesdev/hubble.md) 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 bholmesdev/hubble.md --skill changelog -a codex`. Or copy the skill folder (.agents/skills/changelog in bholmesdev/hubble.md) 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 bholmesdev/hubble.md --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?

Going by SKILL.md and its folder, Changelog needs the command-line tools its instructions call (gh).

Does Changelog access the network?

SKILL.md names 1 domain. In commands or code: github.com; the agent is likely to contact it when it follows the instructions. 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 564 tokens (SKILL.md is roughly 2.3k 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: Simple English (moeru-ai/airi, 50k stars), StarRocks Release Notes (StarRocks/starrocks, 12k stars), Cutting A Release (TriliumNext/Trilium, 38k stars) and React Router Release Notes Prep (remix-run/react-router, 57k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Changelog?

bholmesdev (a GitHub user) maintains it in bholmesdev/hubble.md, which has 1,483 GitHub stars. The repository holds 13 skills in this directory. The repository was last updated on October 1, 2026.

Source: bholmesdev/hubble.md on GitHub. Facts on this page come from the repository at the commit we read; the author's words are quoted as theirs.
