+# Skills Documentation
+
+## Overview
+
+OpenClaw employs AgentSkills-compatible skill folders to teach the agent how to use tools with a three-tier loading system prioritizing workspace skills over managed skills and bundled options.
+
+## Loading Hierarchy
+
+Skills are sourced from three locations in precedence order:
+
+1. Workspace-specific directories (`<workspace>/skills`)
+2. Machine-level managed folders (`~/.openclaw/skills`)
+3. Application bundled skills (lowest priority)
+
+Additional directories can be configured via `skills.load.extraDirs` in the OpenClaw configuration file.
+
+## Multi-Agent Considerations
+
+In systems with multiple agents, each workspace maintains its own per-agent skills collection, while shared skills live in ~/.openclaw/skills (managed/local) and are visible to all agents on the same machine.
+
+## Skill Format Requirements
+
+Skills must include a `SKILL.md` file with YAML frontmatter containing:
+- `name`: skill identifier
+- `description`: functionality summary
+- Optional `metadata` as single-line JSON for gating/configuration
+
+## Security Practices
+
+The documentation emphasizes treating third-party skills as untrusted code. Read them before enabling and recommends sandboxed execution for risky operations. Secrets injected via environment variables affect the host process only during that agent turn.
+
+## Discovery & Installation
+
+ClawHub (clawhub.com) serves as the public skills registry, enabling installation, updates, and synchronization through command-line interface tools.
