What is a SKILL.md file in OpenClaw?

A SKILL.md file is the instruction manifest that defines a Skill in OpenClaw, describing what the skill does and what capabilities or permissions it declares needing.

• Loaded into the agent's context so the model knows the skill exists and how to use it
• The declared permissions in this manifest provide a form of capability transparency, letting an operator see upfront what a skill claims to need
• Notably, this format is portable across different agent ecosystems, not unique to OpenClaw alone

A key limitation worth knowing: these declared permissions are self-reported by the skill's author, there's no independent runtime check confirming a skill's actual behavior matches what its SKILL.md claims.
