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 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 1mo 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 — 192 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Context

  • Latest tag: !git describe --tags --abbrev=0 2>/dev/null || echo "No tags found"
  • Commits since last tag: !TAG=\git describe --tags --abbrev=0 2>/dev/null || echo "HEAD~20"`; git log "$TAG"..HEAD --format="%h %s" 2>/dev/null | head -15 || echo "No commits found"`
  • Repository: !basename \git rev-parse --show-toplevel 2>/dev/null` 2>/dev/null || echo "unknown"`

If $ARGUMENTS is empty or not provided:

Generate a changelog from commits since the last release tag.

Usage: /changelog [starting-point]

Examples:

  • /changelog - Since last tag
  • /changelog v1.2.0 - Since specific tag
  • /changelog HEAD~50 - Last 50 commits
  • /changelog 2024-01-01 - Since date

Workflow:

  1. Find the latest git tag
  2. Parse commits using Conventional Commits format
  3. Group by type (Added, Fixed, Changed, etc.)
  4. Generate Keep a Changelog formatted output

Proceed with commits since last tag.


If $ARGUMENTS is provided:

Generate a changelog from git commits since the specified starting point.

Configuration

  • Since: $ARGUMENTS (tag, commit ref, or date)

Steps

  1. Identify Release Points

    • Find the latest tag: git describe --tags --abbrev=0 2>/dev/null || echo ""
    • If $ARGUMENTS provided, use as starting point
    • If no tags exist, use first commit or a reasonable limit (last 100 commits)
  2. Gather Commits Run: git log <since>..HEAD --format="%H|%s|%b|%an|%ae" --reverse

    For each commit, extract:

    • Hash (for linking)
    • Subject line
    • Body (for breaking changes, closes/fixes references)
    • Author info
  3. Parse Conventional Commits Categorize commits into Keep a Changelog sections:

    Conventional Commit Changelog Section
    feat:, feature: Added
    fix:, bugfix: Fixed
    perf: Changed (Performance)
    refactor: Changed
    docs: Changed (Documentation)
    BREAKING CHANGE: Changed (Breaking)
    deprecate: Deprecated
    remove: Removed
    security: Security
    chore:, build:, ci:, test: (Skip or group as "Other")

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.
