What it does

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

Its SKILL.md is about 260 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: fear, uncertainty and ... terminals.

When your agent uses it

  • Wrapping up a feature
  • Asked to record what changed

Example prompts

  • “/changelog”

Workflow steps

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

  1. Open the root CHANGELOG.md.
  2. Add one bullet under ## Unreleased.
  3. Write it for a user reading release notes, not as a commit message

What it can do on your machine

Read from SKILL.md and the folder at commit b62d0ee. 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

    No URLs in SKILL.md.

    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 256 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 126 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~38
When it runs · the whole SKILL.md, loaded when a task matches
~256

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

Without a licence we can't republish the file, so here is its outline and opening line. It has 126 words (~256 tokens).

“Record what shipped while the change is fresh. Do not reconstruct the changelog from commits at release time.”
