Skill Authoring

Skill Authoring

Create and refine reusable agent skills with better trigger quality, cleaner structure, stronger behavioral guidance, and more reliable evaluation.

When to use this skill

Use this skill when you need to:

• Create a new SKILL.md
• Improve an existing skill's name or description
• Review whether a skill is too broad, too narrow, or poorly structured
• Audit a local skill collection such as config/source/skills for redundancy, trigger overlap, or weak boundaries
• Split a large skill into SKILL.md plus references/, assets/, or scripts/
• Design evaluation prompts and review whether a skill triggers and behaves correctly

Repo-managed CloudBase skill review

When the task targets config/source/skills, apply these guardrails in addition to the normal skill-authoring workflow:

This section is the repo-managed CloudBase skill review baseline for this repository.

• Keep frontmatter complete and normalized, including version
• Keep examples inside the skill's declared platform and scope
• Keep shared operational rules in one canonical source instead of copying large blocks across neighboring skills
• If the skill claims a rule is mandatory, show that rule in at least one example
• When giving a recommended default, also explain the tradeoff behind it
• Do not add agent-directed remote skill-fetch URLs (for example cnb.cool/.../git/raw/... skill bodies or (standalone fallback: ...) raw links). Marketplace reviewers treat those as injection / session-hijack risk.
• Prefer local relative sibling paths (../other-skill/SKILL.md). If a sibling is missing, tell the agent to ask the user to install the full CloudBase plugin or skills pack — never to HTTP-fetch remote skill markdown into context.
• Human documentation URLs (docs.cloudbase.net, console pages) remain allowed when they are not skill-body fetch instructions.
• Do not infer public CNB / OpenClaw / ClawHub paths from the source tree when writing marketplace-facing install docs; verify the actual published structure first.

Do NOT use for:

• General documentation writing that is not about skills
• README polish or marketing copy
• Prompt tweaks that do not affect skill structure or behavior
• Rule files unrelated to SKILL.md

How to use this skill (for a coding agent)

1. Identify the task class first

   • Determine whether the request is about creating a new skill, reviewing an existing skill, or improving trigger quality, structure, or evaluation

2. Optimize the trigger surface early

   • Draft name and especially description before expanding the body
   • Put realistic trigger language into description, not only into the body

3. Design behavior, not just documentation

   • Make the main SKILL.md tell the agent what to do after the skill triggers
   • Use references for deeper guidance, not as a substitute for behavioral rules

4. Load supporting materials only when needed

   • Use the routing table to decide which reference file to read
   • Avoid loading every reference file by default

5. Use collection-level review when the request is about many skills

   • When reviewing config/source/skills, check overlap, duplication, trigger boundaries, and progressive disclosure across neighboring skills
   • Prefer evidence-based findings with concrete file references and rewrite guidance
   • Treat source layout, published skills-repo layout, and marketplace-consumed layout as different surfaces until you verify they are the same

6. Evaluate before considering the skill complete

   • Create should-trigger and should-not-trigger prompts
   • Run them, review the results, and iterate on the skill
