"""
flatten_agents.py -- Promote every nested agent to a top-level sibling.
Claude Code's /agents Library tab auto-discovers ONLY top-level .md files in
~/.claude/agents/. Agents living in category subdirs (design/, engineering/,
game-development/, etc.) are invisible to the Library — there are 169 such
orphans across 15 folders.
This script walks ~/.claude/agents/ and for every nested .md file with YAML
frontmatter containing a `name:` field (i.e. a real agent, not a reference
note), it writes a sibling copy at the top level. The original nested file is
left untouched so existing references still resolve.
Safety:
- Skips files with no frontmatter (reference notes, includes).
- Skips if a sibling with the same basename already exists (no collision risk
— verified at time of writing, but re-checked here).
- Dry-run by default; pass --apply to actually write.
Usage:
python src/flatten_agents.py # dry run, print plan
python src/flatten_agents.py --apply # perform the flatten
python src/flatten_agents.py --apply -v # verbose
