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

smart-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 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.

Smart Changelog Generator

Generate professional changelogs and release notes from your git history.

When to Activate

  • User says /smart-changelog, "generate changelog", "release notes", or "what changed"
  • User wants to prepare a release
  • User asks about version bumping or semantic versioning

Instructions

Step 1: Determine the Range

Figure out what commits to include:

# List recent tags
git tag --sort=-version:refname | head -10

# Find the latest tag
git describe --tags --abbrev=0 2>/dev/null || echo "no tags"

# If no tags, use the first commit
git rev-list --max-parents=0 HEAD

Range logic:

  • If user specifies a range (e.g., "since v1.2.0"): use that
  • If tags exist: use <latest-tag>..HEAD
  • If no tags: use all commits (first release)

Ask the user if unclear:

  • "I see the latest tag is v1.3.0. Should I generate changes since then?"
  • "No tags found — should I include all commits, or specify a starting point?"

Step 2: Gather Commits

# Full commit log with hash, subject, body, and author
git log <range> --format='%H|%s|%b|%an' --no-merges

# Or with merge commits if the project uses merge-based workflow
git log <range> --format='%H|%s|%b|%an' --first-parent

Also check for:

# Any breaking changes?
git log <range> --grep='BREAKING' --format='%H %s'

# Linked issues/PRs?
git log <range> --grep='#[0-9]' --format='%H %s'

Step 3: Categorize Commits

If the project uses Conventional Commits:

Parse the type prefix to categorize:

Type Category Emoji
feat Added
fix Fixed 🐛
perf Performance
refactor Changed ♻️
docs Documentation 📚
test Tests 🧪
chore Maintenance 🔧
ci CI/CD 🏗️
style Style 🎨
revert Reverted
BREAKING CHANGE Breaking 💥
If NOT using Conventional Commits:

Analyze each commit's diff and message to categorize:

# Get the diff stat for context
git show --stat <hash>

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.
