A collection of agent skills for AI coding assistants. This repository provides reusable, composable skills that extend the capabilities of Claude Code, OpenCode, and other AI development tools.
Agent skills are modular, self-contained tools that AI assistants can invoke to perform specialized tasks. This collection includes skills for code analysis, session insights, report generation, and more.
Install all skills from this collection:
npx skills add hellosunghyun/agent-skillsOr install a specific skill:
npx skills add hellosunghyun/agent-skills@insightsNote: Use the
@skillsyntax (not/skill) to select a specific skill.
After installation, the skill is automatically available to your AI coding assistant. Just ask naturally:
- "Analyze my coding sessions"
- "Generate an insights report"
- "Show me my workflow patterns"
The agent reads the installed SKILL.md and follows the orchestration steps — running scripts, collecting data, and producing results autonomously.
Analyzes AI coding assistant sessions and generates actionable insights. Auto-detects Claude Code, OpenCode, and Codex sessions, extracts command patterns, and produces HTML reports with statistics and recommendations.
Features:
- Auto-detects CLI type (Claude Code, OpenCode, Codex)
- Collects and aggregates session metadata
- Runs 8 categories of qualitative analysis
- Generates a self-contained HTML report with dark/light theme
- Multi-language support (English, Korean)
Requirements: bash 4+, jq
We welcome contributions! To add a new skill:
- Create a new directory under
skills/with your skill name (kebab-case) - Add a
SKILL.mdfile documenting the skill - Implement skill scripts in
scripts/subdirectory - Add tests in
