About this catalog

This is the public face of the Skills Sync System. One canonical registry powers four destinations:

• HQ project — landing page top-nav Skills section + post-login sidebar.
• md.sgnk.ai — Skills folder rendered inside the vault editor.
• Obsidian vault — Skills folder with frontmatter, tags, and backlinks.
• skills.sgnk.ai (this site) — the public catalog you’re reading.

Source systems

• Claude (~/.claude/skills)
• Codex (~/.codex/skills + project-level AGENTS.md)
• Antigravity (configurable; opt-in)

Pipeline

Claude / Codex / Antigravity
        ↓  scanner + normalizer (scripts/sync.mjs)
   skills.registry.json  ←  canonical source of truth
        ↓  fan-out
HQ landing · HQ sidebar · md.sgnk.ai · Obsidian · skills.sgnk.ai

Normalized shape

Every skill is normalized to exactly two files:

• skill.md — what the skill is, capabilities, when to use, dependencies.
• workflow.md — how the skill executes, step-by-step, edge cases, integration notes.

Sync rules

• Add → fan out to every destination, append to registry.
• Update → re-write only the changed files, bump lastUpdated.
• Delete → archive under _Archived/, never hard-delete.
• Conflict → write a conflict report; never silently overwrite a destination edit.
