skill-041

skill-041 is a skill for Claude Code, Codex from legendtkl/agentic-skill-router. It costs 14 tokens per session (359 once invoked), scanned A, original, MIT.

A skill that updates CHANGELOG.md, the file that records project changes, from recent Git commit history. It also tracks which commit was last included.

In plain words
What is it for?
Use it after development work to add unreleased changes to a changelog using the project's required format.
Why use it?
It avoids manually reviewing commits and helps prevent the same changes from being added to the changelog twice.

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

skill-041 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 7d 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.

What it actually says

Edit changelog

GOAL: generate changelog entries from git history and update CHANGELOG.md.

WHEN: the agent needs to update the changelog with recent commits.

NOTE: requires CHANGELOG.md and .last-aggregated-commit (auto-initialized).

Efficiency directives

  • Optimize all operations for token and context efficiency
  • Batch operations on file groups, avoid individual file processing
  • Target only relevant files
  • Reduce token usage

Workflow

  • Run scripts/edit-changelog.sh
  • Capture status from first line of output
  • Handle the status:
    • If ERROR: Stop and report to user
    • If WARN: Report no changes needed
    • If SUCCESS: Report success with entry count
  • DONE

Output

Files modified:

  • CHANGELOG.md - Unreleased section updated
  • .last-aggregated-commit - Updated to HEAD

Status communication:

First line of output indicates status:

  • SUCCESS: [message] - Operation completed with changes
  • WARN: [message] - Operation completed but no changes needed
  • ERROR: [message] - Operation failed

References

The following reference files serve as strict guidelines:

  • references/keep-a-changelog-spec.md: Format specification
  • references/changelog-templates.md: Template variations
  • references/changelog-structure.md: Structure documentation
  • references/aggregation-patterns.md: Aggregation patterns
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.
