The open agent skills ecosystem

wittyhub-cli

The CLI for the open agent skills ecosystem.

Supports OpenCode, Claude Code, Codex, Cursor, and 68 more.

Install a Skill

npx wittyhub add vercel-labs/agent-skills

Use a Skill Without Installing

Generate a prompt for one skill, or start a supported coding agent interactively:

npx wittyhub use vercel-labs/agent-skills@web-design-guidelines | claude
npx wittyhub use vercel-labs/agent-skills --skill web-design-guidelines --agent claude-code

wittyhub use resolves sources the same way as wittyhub add, writes the selected skill files to a temporary directory, and prints only the generated prompt to stdout unless --agent is provided. With --agent, it starts one supported agent interactively with the generated prompt.

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 | Project Path | Global Path | |-------|-----------|--------------|-------------| | AiderDesk | aider-desk | .aider-desk/skills/ | ~/.aider-desk/skills/ | | Amp, Replit, Universal | amp, replit, universal | .agents/skills/ | ~/.config/agents/skills/ | | Antigravity | antigravity | .agents/skills/ | ~/.gemini/antigravity/skills/ | | Antigravity CLI | antigravity-cli | .agents/skills/ | ~/.gemini/antigravity-cli/skills/ | | AstrBot | astrbot | data/skills/ | ~/.astrbot/data/skills/ | | Autohand Code CLI | autohand-code | .autohand/skills/ | ~/.autohand/skills/ | | Augment | augment | .augment/skills/ | ~/.augment/skills/ | | IBM Bob | bob | .bob/skills/ | ~/.bob/skills/ | | Claude Code | claude-code | .claude/skills/ | ~/.claude/skills/ | | OpenClaw | openclaw | skills/ | ~/.openclaw/skills/ | | Cline, Dexto, Kimi Code CLI, Loaf, Warp, Zed | cline, dexto, kimi-code-cli, loaf, warp, zed | .agents/skills/ | ~/.agents/skills/ | | CodeArts Agent | codearts-agent | .codeartsdoer/skills/ | ~/.codeartsdoer/skills/ | | CodeBuddy | codebuddy | .codebuddy/skills/ | ~/.codebuddy/skills/ | | Codemaker | codemaker | .codemaker/skills/ | ~/.codemaker/skills/ | | Code Studio | codestudio | .codestudio/skills/ | ~/.codestudio/skills/ | | Codex | codex | .agents/skills/ | ~/.codex/skills/ | | Command Code | command-code | .commandcode/skills/ | ~/.commandcode/skills/ | | Continue | continue | .continue/skills/ | ~/.continue/skills/ | | Cortex Code | cortex | .cortex/skills/ | ~/.snowflake/cortex/skills/ | | Crush | crush | .crush/skills/ | ~/.config/crush/skills/ | | Cursor | cursor | .agents/skills/ | ~/.cursor/skills/ | | Deep Agents | deepagents | .agents/skills/ | ~/.deepagents/agent/skills/ | | Devin for Terminal | devin | .devin/skills/ | ~/.config/devin/skills/ | | Droid | droid | .factory/skills/ | ~/.factory/skills/ | | Eve | eve | agent/skills/ | N/A (project-only) | | Firebender | firebender | .agents/skills/ | ~/.firebender/skills/ | | ForgeCode | forgecode | .forge/skills/ | ~/.forge/skills/ | | Gemini CLI | gemini-cli | .agents/skills/ | ~/.gemini/skills/ | | GitHub Copilot | github-copilot | .agents/skills/ | ~/.copilot/skills/ | | Goose | goose | .goose/skills/ | ~/.config/goose/skills/ | | Hermes Agent | hermes-agent | .hermes/skills/ | ~/.hermes/skills/ | | inference.sh | inference-sh | .inferencesh/skills/ | ~/.inferencesh/skills/ | | Jazz | jazz | .jazz/skills/ | ~/.jazz/skills/ | | Junie | junie | .junie/skills/ | ~/.junie/skills/ | | iFlow CLI | iflow-cli | .iflow/skills/ | ~/.iflow/skills/ | | Kilo Code | kilo | .kilocode/skills/ | ~/.kilocode/skills/ | | Kiro CLI | kiro-cli | .kiro/skills/ | ~/.kiro/skills/ | | Kode | kode | .kode/skills/ | ~/.kode/skills/ | | Lingma | lingma | .lingma/skills/ | ~/.lingma/skills/ | | MCPJam | mcpjam | .mcpjam/skills/ | ~/.mcpjam/skills/ | | Mistral Vibe | mistral-vibe | .vibe/skills/ | ~/.vibe/skills/ | | Moxby | moxby | .moxby/skills/ | ~/.moxby/skills/ | | Mux | mux | .mux/skills/ | ~/.mux/skills/ | | OpenCode | opencode | .agents/skills/ | ~/.config/opencode/skills/ | | OpenHands | openhands | .openhands/skills/ | ~/.openhands/skills/ | | Ona | ona | .ona/skills/ | ~/.ona/skills/ | | Pi | pi | .pi/skills/ | ~/.pi/agent/skills/ | | Qoder | qoder | .qoder/skills/ | ~/.qoder/skills/ | | Qoder CN | qoder-cn | .qoder/skills/ | ~/.qoder-cn/skills/ | | Qwen Code | qwen-code | .qwen/skills/ | ~/.qwen/skills/ | | Reasonix | reasonix | .reasonix/skills/ | ~/.reasonix/skills/ | | Rovo Dev | rovodev | .rovodev/skills/ | ~/.rovodev/skills/ | | Roo Code | roo | .roo/skills/ | ~/.roo/skills/ | | Tabnine CLI | tabnine-cli | .tabnine/agent/skills/ | ~/.tabnine/agent/skills/ | | Terramind | terramind | .terramind/skills/ | ~/.terramind/skills/ | | Tinycloud | tinycloud | .tinycloud/skills/ | ~/.tinycloud/skills/ | | Trae | trae | .trae/skills/ | ~/.trae/skills/ | | Trae CN | trae-cn | .trae/skills/ | ~/.trae-cn/skills/ | | Windsurf | windsurf | .windsurf/skills/ | ~/.codeium/windsurf/skills/ | | Zencoder, Zenflow | zencoder, zenflow | .zencoder/skills/ | ~/.zencoder/skills/ | | Neovate | neovate | .neovate/skills/ | ~/.neovate/skills/ | | Pochi | pochi | .pochi/skills/ | ~/.pochi/skills/ | | PromptScript | promptscript | .agents/skills/ | N/A (project-only) | | AdaL | adal | .adal/skills/ | ~/.adal/skills/ |

[!NOTE] Kiro CLI users: The default agent automatically loads skills from .kiro/skills/ and ~/.kiro/skills/ — no configuration needed. If you use a custom agent, add skills to its 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. Each skill container directory is walked one level deep for the common flat layout (skills/<name>/SKILL.md) and one extra level deep for catalog layouts (skills/<category>/<name>/SKILL.md). A SKILL.md discovered at the shallower level shadows anything nested below it. Use --full-depth to also discover SKILL.md files outside these container directories (e.g. under examples/ or tests/).

Root directory (if it contains SKILL.md)
skills/
skills/.curated/
skills/.experimental/
skills/.system/
.aider-desk/skills/
.agents/skills/
data/skills/
.autohand/skills/
.augment/skills/
.bob/skills/
.claude/skills/
.codeartsdoer/skills/
.codebuddy/skills/

.terramind/skills/
.tinycloud/skills/
.trae/skills/
.windsurf/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. Skill paths declared in a manifest are searched at their declared depth and are not subject to the depth-2 catalog walk described above.

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 | Yes | 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 wittyhub add vercel-labs/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.
