Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Changelog Curator scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 173 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Changelog Curator

What this skill does

This skill directs the agent to write or update a CHANGELOG.md that follows the Keep a Changelog format. It takes a list of commits, PR titles, or a git log dump, groups changes into the correct categories (Added, Changed, Fixed, Removed, Deprecated, Security), writes them in clear human-readable language, and formats the file correctly with semantic versioning and dates.

Use this before cutting a release, during sprint wrap-up, or when your changelog has fallen behind and you need to bring it up to date.

How to use

Claude Code / Cline

Copy this file to .agents/skills/changelog-curator/SKILL.md in your project root.

Then ask:

  • "Use the Changelog Curator skill to update CHANGELOG.md for the v2.3.0 release. Here's the git log: [paste log]."
  • "Use the Changelog Curator skill to create a CHANGELOG.md for these PRs: [list PRs]."

Provide:

  • The git log (git log --oneline vX.Y.Z..HEAD) or a list of PR titles/descriptions
  • The new version number and release date (or "Unreleased")
  • The existing CHANGELOG.md if one exists (so the agent can append, not overwrite)

Cursor

Add the instructions below to your .cursorrules or paste them into the Cursor AI pane. Paste the git log or PR list along with the version number.

Codex

Paste the git log or PR list, the current CHANGELOG.md if it exists, and the version number. Ask Codex to follow the instructions below.

The Prompt / Instructions for the Agent

When asked to write or update a changelog, follow these steps:

Step 1 — Parse the input

The input may be:

  • A raw git log --oneline dump
  • A list of PR titles
  • A mix of both

For each item, extract:

  • The core change (ignore ticket numbers, PR numbers, merge commit boilerplate like "Merge branch X")
  • The type of change (what category does it belong to?)
  • The user-facing impact (what does a user or developer actually experience?)

Step 2 — Categorize each change

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
