What it does

Changelog is an agent skill from hashgraph-online/awesome-codex-plugins. Record shipped work in the monthly changelog (append-only). Use when something ships or when asked "what changed", "add to changelog", "release notes", or "what shipped this month".

Its SKILL.md is about 930 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: A curated list of awesome OpenAI Codex / ChatGPT plugins, skills, and resources. The 1 Codex Marketplace. See live plugins at: https://hol.org/plugins/best-codex-plugins. The licence is Apache-2.0.

When your agent uses it

  • Something ships
  • Asked what changed
  • Add to changelog
  • What shipped this month

Example prompts

  • “what changed”
  • “add to changelog”
  • “release notes”
  • “/changelog”

Workflow steps

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

  1. One file per month
  2. Anatomy of a month file
  3. The shipping flow (where changelog fits)
  4. Generating an entry from git
  5. Why append-only matters

What it can do on your machine

Read from SKILL.md and the folder at commit 9e7b281. 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

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

  • Network

    No URLs in SKILL.md. Its commands use git, 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

Changelog loads about 930 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 364 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~930

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.

changelog

The memory of the knowledge base. Every month gets one file; history is append-only. This is what the SessionStart hook surfaces so the agent starts each session knowing recent work. Pairs with author and router.

Golden rule: never delete or rewrite shipped history. Reversals get a new entry, not an edit.

Writing style (enforce)

Direct, tech + business. No filler. Outcome first.

  • Each entry = a small table (Outcome / Delivered / Business impact / Commits). No narrative paragraphs.
  • Summary = 4 bullets max: release type, biggest business change, biggest technical change, prod risk/action.
  • Concrete only: feature names, paths, hashes, numbers. Cut adjectives.

1 — One file per month

changelog/(mmm-yy).md — lowercase 3-letter month + 2-digit year: (apr-26).md, (may-26).md. changelog/README.md is the index: a table of | Month | Highlights |, newest first.

Link to a month file (parens need angle brackets): [may-26](<(may-26).md>).


2 — Anatomy of a month file

markdown
# Month YEAR — <release / period title>

> Window: `<base>` (`hash`, date) → `<head>` (`hash`, date). Scope: `N` commits.

## Summary
- Release type: patch | feature | architectural
- Biggest business change: <one line>
- Biggest technical change: <one line>
- Risk / action for prod: <one line>

## What Changed

### 1. <Feature / theme>
| | |
|---|---|
| Outcome | <one line> |
| Delivered | <bullet; bullet> |
| Business impact | <one line> |
| Commits | `<hash>` <desc>; `<hash>` <desc> |

### 2. <next theme>

A reader skimming the Outcome rows alone should understand the release.


3 — The shipping flow (where changelog fits)

The roadmap (plans/upcoming/) and the changelog are two ends of one pipe:

plans/upcoming/{critical,now,next,later}.md   ── ships ──►   changelog/(mmm-yy).md
        (what's coming)                                        (what landed)

When something ships:

  1. Move the line out of the plans/upcoming/* horizon — don't let shipped work linger there (it kills the roadmap's signal).
  2. Add / update the entry in the current changelog/(mmm-yy).md.
  3. Cross-link: the feature plan's ## What shipped table references the changelog month; the ADR/spec stay linked from the plan.
  4. If a known bug got fixed, move it from reviews/bugs/open.md to reviews/bugs/fixed.md with the commit ref.

plans/upcoming/README.md keeps a short "Recently shipped" pointer list to the last few months — pointers only, no restating.

4 — Generating an entry from git

To build a month/release entry, diff the two refs and group commits by theme:

bash
# commits in head not yet in base, newest first
git log --no-merges --pretty='%h %ad %s' --date=short BASE..HEAD
# count for the scope line
git rev-list --count --no-merges BASE..HEAD

Then: cluster commits into 3–8 themes → write a ### N. Theme block each → fill outcome / delivered / why / commits → write the Executive Summary last (it summarizes the blocks).


5 — Why append-only matters

The changelog is the project's long-term memory. An agent (or a new teammate) that reads the newest one or two month files gets the recent trajectory: what was built, why it mattered, which commits. Editing or pruning old months erases that trail. Superseded decisions are recorded as new lines that reference the old — the history of the change is itself information.
