Skills and Plugins

FastClaw supports two extension layers:

• Skills: instruction bundles under skills/ or agents/<id>/agent/skills/.
• Plugins: JSON-RPC subprocesses that can add tools, hooks, providers, or channel adapters.

Built-in Skills

FastClaw ships with reusable skills such as:

• code-runner
• image-gen
• data-analysis
• translation
• web-search
• skill-creator

Skill Commands

fastclaw skill list
fastclaw skill search image
fastclaw skill install image-gen
fastclaw skill update --all
fastclaw skill remove image-gen
fastclaw skill info image-gen

Installed global skills live under:

$FASTCLAW_HOME/skills/

Agent-private skills live under:

$FASTCLAW_HOME/agents/<agentId>/agent/skills/

Skill Sources

FastClaw can install skills from:

• Bundled skills
• ClawHub
• skills.sh
• GitHub/tarball sources through the internal installer paths

Plugins

Plugins run as subprocesses and communicate over JSON-RPC. They are appropriate when a capability needs executable code rather than static instructions.

Plugin adapter types in the runtime include:

• tool adapter
• hook adapter
• provider adapter
• channel adapter

Use plugins for long-lived integrations, custom providers, or operational hooks. Use skills for task instructions, workflows, and lightweight tool guidance.
