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-create 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 today.

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.

/skill-create - Local Skill Generation

Analyze your repository's git history to extract coding patterns and generate SKILL.md files that teach Claude your team's practices.

Usage

/skill-create                    # Analyze current repo
/skill-create --commits 100      # Analyze last 100 commits
/skill-create --output ./skills  # Custom output directory
/skill-create --instincts        # Also generate instincts for continuous-learning-v2

What It Does

  1. Parses Git History - Analyzes commits, file changes, and patterns
  2. Detects Patterns - Identifies recurring workflows and conventions
  3. Generates SKILL.md - Creates valid Claude Code skill files
  4. Optionally Creates Instincts - For the continuous-learning-v2 system

Analysis Steps

Step 1: Gather Git Data

# Get recent commits with file changes
git log --oneline -n ${COMMITS:-200} --name-only --pretty=format:"%H|%s|%ad" --date=short

# Get commit frequency by file
git log --oneline -n 200 --name-only | grep -v "^$" | grep -v "^[a-f0-9]" | sort | uniq -c | sort -rn | head -20

# Get commit message patterns
git log --oneline -n 200 | cut -d' ' -f2- | head -50

Step 2: Detect Patterns

Look for these pattern types:

Pattern Detection Method
Commit conventions Regex on commit messages (feat:, fix:, chore:)
File co-changes Files that always change together
Workflow sequences Repeated file change patterns
Architecture Folder structure and naming conventions
Testing patterns Test file locations, naming, coverage

Step 3: Generate SKILL.md

Output format:

---
name: {repo-name}-patterns
description: Coding patterns extracted from {repo-name}
version: 1.0.0
source: local-git-analysis
analyzed_commits: {count}

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.

skill-create is a command published in the GitHub repository KevinZai/commander (6 stars, last pushed today), licensed MIT. It adds 28 tokens to every session and 1,144 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-04.
