In plain words
What is it for?
It helps create new skills and adapt them to conventions already used in a repository.
Why use it?

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

create-skill 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.

/create-skill - Create a New Skill

Create or generate a SKILL.md file that teaches the AI agent specialized knowledge, workflows, or tool integrations.

Input

User's request: {{input}}

If {{input}} is empty, ask: "What capability should this skill add? Or should I analyze the repo to discover patterns?"


Option A: Create from Description

When the user describes what the skill should do:

  1. Clarify the skill's purpose, triggers, and target workflows
  2. Read the skill creator guide at skills/workflow/skill-creator/SKILL.md for format and best practices
  3. Create the skill following the structure below

Option B: Generate from Repository Analysis

When the user wants to extract patterns from the codebase:

Step 1: Gather Data

# Recent commits with file changes
git log --oneline -n 200 --name-only --pretty=format:"%H|%s|%ad" --date=short

# Most frequently changed files
git log --oneline -n 200 --name-only | sort | uniq -c | sort -rn | head -20

# Commit message patterns
git log --oneline -n 200 | head -50

Step 2: Detect Patterns

Pattern Type What to Look For
Commit conventions Consistent prefixes (feat:, fix:, chore:)
File co-changes Files that always change together
Workflow sequences Repeated multi-file change patterns
Architecture Folder structure and naming conventions
Testing patterns Test locations, naming, framework

Step 3: Generate SKILL.md

Create the skill from detected patterns.

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.
