What it does

Changelog Append is an agent skill from gweslab/cerf. Add a changelog entry for a change that was just made (only user triggered, no agent self-invocation).

Its SKILL.md is about 860 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: Universal Windows CE Emulator - CE Runtime Foundation. The licence is MIT.

When your agent uses it

  • Tasks that involve Changelog and release notes

Example prompts

  • “/changelog-append”

Requirements

  • Python 3

Workflow steps

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

  1. Open docs/changelog.yml. The latest version is the topmost list entry (currently TBA at the top).
  2. Pick the group + subcategory from the legend above. If that group: / subcat: key already exists in the top entry, append your line to its…
  3. Write one raw line. Plain string - no escaping; colons and <, &, quotes are fine. text renders bold. Strip a prefix that just repeats the…
  4. Run python compile_readme.py (from repo root). Confirm it prints README.md compiled (vX.Y).

What it can do on your machine

Read from SKILL.md and the folder at commit 6b8df83. 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:

    • python

    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 Append loads about 864 tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 438 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~864

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.

name
changelog-append
description
Add a changelog entry for a change that was just made (only user triggered, no agent self-invocation).

changelog-append - record one change in the changelog

The user invoked /changelog-append. Add one concise entry for the change just made, then regenerate the README.

User-invoked only. Only the user triggers this skill by typing /changelog-append. An agent never invokes it on its own initiative - finishing a change is not a license to write the changelog.

Categories

Each change goes under one component group and one subcategory. Order and emoji are applied by tools/changelog.py; the YAML only names the keys.

Component groups:

  • devices - a board/device: new board support, per-board fixes (touch, sound, screen), on-board silicon (SoC RTC, suspend, battery, reset), PC cards / PCMCIA (NE2000, CompactFlash, modem), sleeves.
  • emulator - the CERF core (cerf.exe): JIT / MMU / CPU, VFP/NEON, host UI/UX, hibernation/state saving, the serial stack, host-OS compatibility, board detection, crashes, general fixes.
  • launcher - the launcher tool.
  • ce_apps - CERF-built CE binaries and shipped tools (xplorer, romdump, tools\fileserver.py, bundled CE apps).
  • guest_additions - the Guest Additions subsystem: display driver, ROM injection, mouse/keyboard, shared folders, task manager, DPI, resolution.
  • website - the cerf.cx docs site.

Subcategories:

  • new - an addition: board support, a new feature/app, a redesign or overhaul.
  • fixed - a bug fix, or an improvement/update to existing behavior.
  • deleted - a removal.

Procedure

docs/changelog.yml is the source; the README table and the website changelog page are generated from it.

  1. Open docs/changelog.yml. The latest version is the topmost list entry (currently TBA at the top).
  2. Pick the group + subcategory from the legend above. If that group: / subcat: key already exists in the top entry, append your line to its | block; otherwise add the key (a | literal block) in any order. Do not create a new version entry. Do not touch older entries.
  3. Write one raw line. Plain string - no escaping; colons and <, &, quotes are fine. **text** renders bold. Strip a prefix that just repeats the group (Guest Additions:, Launcher:), but keep a board name that says which device (NEC MP700:, Zune 30:).
  4. Run python compile_readme.py (from repo root). Confirm it prints README.md compiled (vX.Y).

Writing the entry

  • A changelog line, not narration. State what changed to the product, in the fewest words that are still clear. Smaller is better.
  • One line per change. If the work spans clearly separate user-visible changes, add one line each - but do not pad; prefer a single tight line.
  • No conversation echoes, no session history, no model/agent references, no "as you asked".

Example top entry after adding a device fix and a guest-additions feature:

yaml
- version: v6.6
  date: TBA
  devices:
    fixed: |
      Fixed Device Emulator crash booting Windows Mobile 5.2 ROMs
  guest_additions:
    new: |
      Clipboard sharing with the host

Git

Do not run any git command unless the user explicitly asks (e.g. "stage your changes", "commit"). When they do, the changelog edit and the regenerated README.md are both part of the changeset - include both.
