What are Agent Skills?

Agent skills are reusable instruction sets that extend your coding agent's capabilities. They're defined in SKILL.md files with YAML frontmatter containing a name and description.

Skills let agents perform specialized tasks like:

Generating release notes from git history
Creating PRs following your team's conventions
Integrating with external tools (Linear, Notion, etc.)

Discover skills at skills.sh

Supported Agents

Skills can be installed to any of these agents:

| Agent | --agent | ------------------------------------- | -------------------- | Amp, Kimi Code CLI, Replit, Universal | amp, | Antigravity | antigravity | Augment | augment | Claude Code | claude-code | OpenClaw | openclaw | Cline, Warp | cline, | CodeBuddy | codebuddy | Codex | codex | Command Code | command-code | Continue | continue | Cortex Code | cortex | Crush | crush | Cursor | cursor | Deep Agents | deepagents | Droid | droid | Firebender | firebender | Gemini CLI | gemini-cli | GitHub Copilot | github-copilot | Goose | goose | Junie | junie | iFlow CLI | iflow-cli | Kilo Code | kilo | Kiro CLI | kiro-cli | Kode | kode | MCPJam | mcpjam | Mistral Vibe | mistral-vibe | Mux | mux | OpenCode | opencode | OpenHands | openhands | Pi | pi | Qoder | qoder | Qwen Code | qwen-code | Roo Code | roo | Trae | trae | Trae CN | trae-cn | Windsurf | windsurf | Zencoder | zencoder | Neovate | neovate | Pochi | pochi | AdaL | adal | Project Path | Global Path | -------------------- | ---------------------- | ------------------------------- | kimi-cli, replit, universal | .agents/skills/ | ~/.config/agents/skills/ | | .agents/skills/ | ~/.gemini/antigravity/skills/ | | .augment/skills/ | ~/.augment/skills/ | | .claude/skills/ | ~/.claude/skills/ | | skills/ | ~/.openclaw/skills/ | warp | .agents/skills/ | ~/.agents/skills/ | | .codebuddy/skills/ | ~/.codebuddy/skills/ | | .agents/skills/ | ~/.codex/skills/ | | .commandcode/skills/ | ~/.commandcode/skills/ | | .continue/skills/ | ~/.continue/skills/ | | .cortex/skills/ | ~/.snowflake/cortex/skills/ | | .crush/skills/ | ~/.config/crush/skills/ | | .agents/skills/ | ~/.cursor/skills/ | | .agents/skills/ | ~/.deepagents/agent/skills/ | | .factory/skills/ | ~/.factory/skills/ | | .agents/skills/ | ~/.firebender/skills/ | | .agents/skills/ | ~/.gemini/skills/ | | .agents/skills/ | ~/.copilot/skills/ | | .goose/skills/ | ~/.config/goose/skills/ | | .junie/skills/ | ~/.junie/skills/ | | .iflow/skills/ | ~/.iflow/skills/ | | .kilocode/skills/ | ~/.kilocode/skills/ | | .kiro/skills/ | ~/.kiro/skills/ | | .kode/skills/ | ~/.kode/skills/ | | .mcpjam/skills/ | ~/.mcpjam/skills/ | | .vibe/skills/ | ~/.vibe/skills/ | | .mux/skills/ | ~/.mux/skills/ | | .agents/skills/ | ~/.config/opencode/skills/ | | .openhands/skills/ | ~/.openhands/skills/ | | .pi/skills/ | ~/.pi/agent/skills/ | | .qoder/skills/ | ~/.qoder/skills/ | | .qwen/skills/ | ~/.qwen/skills/ | | .roo/skills/ | ~/.roo/skills/ | | .trae/skills/ | ~/.trae/skills/ | | .trae/skills/ | ~/.trae-cn/skills/ | | .windsurf/skills/ | ~/.codeium/windsurf/skills/ | | .zencoder/skills/ | ~/.zencoder/skills/ | | .neovate/skills/ | ~/.neovate/skills/ | | .pochi/skills/ | ~/.pochi/skills/ | | .adal/skills/ | ~/.adal/skills/ |

[!NOTE] Kiro CLI users: After installing skills, manually add them to your custom agent's resources in .kiro/agents/<agent>.json:
{
  "resources": ["skill://.kiro/skills/**/SKILL.md"]
}

The CLI automatically detects which coding agents you have installed. If none are detected, you'll be prompted to select which agents to install to.

Creating Skills

Skills are directories containing a SKILL.md file with YAML frontmatter:

---
name: my-skill
description: What this skill does and when to use it
---

# My Skill

Instructions for the agent to follow when this skill is activated.

## When to Use

Describe the scenarios where this skill should be used.

## Steps

1. First, do this
2. Then, do that

Required Fields

name: Unique identifier (lowercase, hyphens allowed)
description: Brief explanation of what the skill does

Optional Fields

metadata.internal: Set to true to hide the skill from normal discovery. Internal skills are only visible and installable when INSTALL_INTERNAL_SKILLS=1 is set. Useful for work-in-progress skills or skills meant only for internal tooling.

---
name: my-internal-skill
description: An internal skill not shown by default
metadata:
  internal: true
---

Skill Discovery

The CLI searches for skills in these locations within a repository:

Root directory (if it contains SKILL.md)
skills/
skills/.curated/
skills/.experimental/
skills/.system/
.agents/skills/
.augment/skills/
.claude/skills/
./skills/
.codebuddy/skills/
.commandcode/skills/
.continue/skills/
.cortex/skills/
.crush/skills/
.factory/skills/
.goose/skills/
.junie/skills/
.iflow/skills/
.kilocode/skills/
.kiro/skills/
.kode/skills/
.mcpjam/skills/
.vibe/skills/
.mux/skills/
.openhands/skills/
.pi/skills/
.qoder/skills/
.qwen/skills/
.roo/skills/
.trae/skills/
.windsurf/skills/
.zencoder/skills/
.neovate/skills/
.pochi/skills/
.adal/skills/

Plugin Manifest Discovery

If .claude-plugin/marketplace.json or .claude-plugin/plugin.json exists, skills declared in those files are also discovered:

// .claude-plugin/marketplace.json
{
  "metadata": { "pluginRoot": "./plugins" },
  "plugins": [
    {
      "name": "my-plugin",
      "source": "my-plugin",
      "skills": ["./skills/review", "./skills/test"]
    }
  ]
}

This enables compatibility with the Claude Code plugin marketplace ecosystem.

If no skills are found in standard locations, a recursive search is performed.

Compatibility

Skills are generally compatible across agents since they follow a shared Agent Skills specification. However, some features may be agent-specific:

| Feature | OpenCode | OpenHands | Claude Code | Cline | CodeBuddy | Codex | Command Code | Kiro CLI | Cursor | Antigravity | Roo Code | Github Copilot | Amp | OpenClaw | Neovate | Pi | Qoder | Zencoder | | --------------- | -------- | --------- | ----------- | ----- | --------- | ----- | ------------ | -------- | ------ | ----------- | -------- | -------------- | --- | -------- | ------- | --- | ----- | -------- | | Basic skills | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | | allowed-tools | Yes | Yes | Yes | Yes | Yes | Yes | Yes | No | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | Yes | No | | context: fork | No | No | Yes | No | No | No | No | No | No | No | No | No | No | No | No | No | No | No | | Hooks | No | No | Yes | Yes | No | No | No | No | No | No | No | No | No | No | No | No | No | No |

Troubleshooting

"No skills found"

Ensure the repository contains valid SKILL.md files with both name and description in the frontmatter.

Skill not loading in agent

Verify the skill was installed to the correct path
Check the agent's documentation for skill loading requirements
Ensure the SKILL.md frontmatter is valid YAML

Permission errors

Ensure you have write access to the target directory.

Environment Variables

| Variable | Description | | ------------------------- | -------------------------------------------------------------------------- | | INSTALL_INTERNAL_SKILLS | Set to 1 or true to show and install skills marked as internal: true | | DISABLE_TELEMETRY | Set to disable anonymous usage telemetry | | DO_NOT_TRACK | Alternative way to disable telemetry |

# Install internal skills
INSTALL_INTERNAL_SKILLS=1 npx @safeskill/cli add example-org/agent-skills --list

Telemetry

This CLI collects anonymous usage data to help improve the tool. No personal information is collected.

Telemetry is automatically disabled in CI environments.
