Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is corv89/shannot's own configuration. It tells Claude Code how to work on shannot itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything shannot configures →

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.

Fable 5.1 $0.00013 $0.00601
Opus 5.5 $0.00005 $0.00240

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 2mo 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.

/changelog - Generate Changelog Entry

Purpose

Generate a Keep a Changelog entry matching the existing CHANGELOG.md style, if available.

Usage

/changelog [version]

Version is optional — suggest one based on the changes (patch for fixes, minor for features, major for breaking changes).

Process

  1. Find the last tag and get commits

    git describe --tags --abbrev=0
    git log --pretty=format:'%s' <tag>..HEAD
    
  2. Categorize using Keep a Changelog sections

    • ### Features — new capabilities
    • ### Changed — breaking or notable behavior changes
    • ### Enhancements — improvements to existing features
    • ### Bug Fixes — things that were broken
    • ### Removed — removed features (rare)
  3. Write entries in a consistent voice

    Match the existing style:

    • Start with imperative verb or noun phrase
    • Bold key concepts on first mention: **Overlay commit model for file writes**:
    • Sub-bullets for details when a feature has multiple parts
    • Technical but accessible — users are developers

    Examples:

    • Fix login regression: use OAuth2 instead of deprecated token flow
    • Improve CLI help with quick start guide and clearer description
    • **Remote file sync**: sync_remote() now supports conflict detection
  4. Skip internal-only changes

    Omit: CI tweaks, refactoring without user impact, dependency bumps (unless security-related)

  5. Output format

    ## [x.y.z] - YYYY-MM-DD
    
    ### Features
    
    - **Feature name**: Description of what users can now do
    
    ### Bug Fixes
    
    - Fix specific thing that was broken
    
  6. Prepend to CHANGELOG.md

    If CHANGELOG.md doesn't exist, create it with this header:

    # Changelog
    
    All notable changes to this project will be documented in this file.
    
    The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/),
    and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

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.
