Skill frontmatter audit: consistent trigger, allowed-tools, user-invocable fields

[dean0x]

Summary

Audit all ~44 skills for consistent frontmatter fields. During the per-feature KB review (PR #193), inconsistencies were found between apply-feature-kb and apply-knowledge — these were fixed, but a systematic audit of all skills is needed.

Fields to Audit

Field	Expected Pattern
trigger	Only present when auto-activation is needed; omit for agent-loaded skills
allowed-tools	Inline format (allowed-tools: Read) for simple cases; block list for multiple tools
user-invocable	Explicitly set for all skills; false for agent-consumed skills

Scope

• All 44 skills in shared/skills/
• Verify consistency within skill categories (apply-* skills, orch skills, domain skills)
• Document any intentional deviations

Acceptance Criteria

• All skills audited for the 3 fields above
• Inconsistencies documented and resolved
• No unintended trigger fields on agent-consumed skills
• allowed-tools format is consistent within categories
