# Agent bootstrap: creates agents from accumulated cortex knowledge
# Called from SessionStart hook (async) — doesn't block the session
#
# Flow:
#   1. Quick check: does current project need agents? (fast, no LLM)
#   2. Cooldown check: already bootstrapped today? (skip if so)
#   3. Collect cortex memories for the project (full content, grouped)
#   4. ONE call to claude -p (haiku) to propose agents
#   5. fleet_create.py creates with semantic dedup (threshold 0.55)
#
# Safety:
#   - Max 3 agents per run (hard cap in fleet_create.py's agents[:5] + prompt)
#   - Cooldown: once per project per day
#   - Semantic dedup: cosine distance < 0.55 = skip
#   - Total cap: if project already has 5+ agents, skip entirely

## CRITICAL RULES

1. Output a JSON array. NO markdown wrapping, NO explanation — JUST the JSON array.
2. Maximum 3 agents TOTAL across all projects and global combined.
3. Each agent must cover a DISTINCT domain — no overlapping scope.
4. Do NOT create an agent if an existing one already covers that domain.
5. If no agents are needed, return: []

## Two Scopes

- "project": specific to this project's workflows (goes in .claude/agents/)
- "user": cross-project patterns useful everywhere (goes in ~/.claude/agents/)

## Agent Quality Requirements

- description: SPECIFIC trigger conditions ("Use when..." or "Use for...")
- System prompt: include ACTUAL knowledge from memories — paths, commands, gotchas, patterns
- tools: [Read, Edit, Write, Bash, Grep, Glob] for most agents
- model: opus (always)

## Output Format

[{"scope": "project", "filename": "kebab-case.md", "content": "---\nname: agent-name\ndescription: When to use this\ntools:\n  - Read\n  - Edit\n  - Write\n  - Bash\n  - Grep\n  - Glob\nmodel: opus\n---\n\nSystem prompt here with real knowledge..."}]
