Hands Registry

Hands are pre-packaged capability bundles that compose agents, tools, skills, MCP servers, and plugins into a working application. Installing a hand gives you a complete, ready-to-use workflow — not just a single agent.

"You have many hands helping you."

A hand can contain one agent (single-agent) or multiple coordinated agents (multi-agent). Each agent in a multi-agent hand can have its own role-specific skills, model config, and capability restrictions.

File Format

Each hand lives in its own subdirectory:

hands/
├── researcher/
│   ├── HAND.toml          # required: hand definition
│   └── SKILL.md           # optional: shared reference knowledge for all agents
├── devteam/
│   ├── HAND.toml
│   ├── SKILL-pm.md        # optional: role-specific knowledge for PM agent
│   ├── SKILL-engineer.md  # optional: role-specific knowledge for Engineer agent
│   └── SKILL-qa.md        # optional: role-specific knowledge for QA agent

Agent templates	base = "coder" on [agents.*]	Inherits prompt, model config, fallbacks from agents/coder/agent.toml
Tools	tools = [...] at hand level	All agents in the hand share these built-in tools
Skills	skills = [...] at hand level	Empty list means all available skills are allowed
MCP servers	mcp_servers = [...] at hand level	Agent interacts via MCP tools, not hardcoded API calls
Plugins	allowed_plugins = [...] at hand level	Empty list means all installed plugins are allowed
Per-agent knowledge	SKILL-{role}.md files	Different reference prompts per agent role
Per-agent capabilities	[agents.*.capabilities]	Fine-grained shell / network / memory per agent

Adding a New Hand

1. Create hands/<name>/HAND.toml with at least id, name, description, and category.
2. Add SKILL.md (shared) or SKILL-{role}.md (per-agent) files for reference knowledge.
3. Use base = "agent-name" in each [agents.*] block to inherit from existing agent templates.
4. Specify mcp_servers, skills, and allowed_plugins for resource composition.
5. Ensure id matches the directory name.
6. Run python scripts/validate.py.
7. Submit a PR.
