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

这是一款实用的技能使用统计工具，能帮助用户了解各类 Skill 的调用频率、成功率和使用状态。文档清晰，示例详细，上手容易。但缺少完整的依赖配置和测试覆盖，稳定性有待验证。适合有技术背景的用户使用，普通用户可能需要一定指导。
