name: skill-stats description: Query, analyze, and track all skill usage information. This skill should be invoked when users ask about skill usage, call counts, success rates, last used time, redundant installations, duplicates, available skills, or any questions related to skill usage details. Supports independent statistics for both Claude Code and OpenClaw environments.

Skill Stats - Skill Usage Statistics

Analyze and track skill usage across Claude Code and OpenClaw environments.

Features

Claude Code

• Scans all session files under ~/.claude/projects/
• Categorizes by scope (builtin/plugin/user/project)
• Shows usage frequency, success rate, and last used time
• Identifies unused and deleted skills

OpenClaw

• Scans all session files under ~/.openclaw/agents/main/sessions/
• Categorizes by scope (openclaw-workspace/openclaw-global)
• Parses toolCall-type skill invocation records
• Stores statistics independently

Usage

Execute the statistics script with the required --context parameter:

Claude Code Environment:

npx -y tsx ${SKILL_DIR}/scripts/main.ts --context claude-code

OpenClaw Environment:

npx -y tsx ${SKILL_DIR}/scripts/main.ts --context openclaw

How It Works

Claude Code

1. Scans all session files (.jsonl) under ~/.claude/projects/
2. Extracts Skill tool invocation records
3. Calculates call counts, success rates, and project usage for each skill
4. Displays results categorized by scope

OpenClaw

1. Scans session files (.jsonl) under ~/.openclaw/agents/main/sessions/
2. Parses toolCall-type skill invocations (via read tool reading SKILL.md)
3. Identifies workspace-level and global-level skills
4. Stores statistics independently

Data Storage

• Claude Code: ~/.claude/skill-stats/global-stats.json
• OpenClaw: ~/.openclaw/skill-stats/openclaw-global-stats.json
