Read(filePath=file)
Extract: key insights, conventions, anti-patterns
Store in EXISTING_AGENTS map
If --create-new: Read all existing first (preserve context) → then delete all → regenerate.

## OVERVIEW
{1-2 sentences: what + core stack}
## STRUCTURE
{root}/ ├── {dir}/ # {non-obvious purpose only} └── {entry}
## WHERE TO LOOK
| Task | Location | Notes |
|------|----------|-------|
## CODE MAP
{From LSP - skip if unavailable or project <10 files}
| Symbol | Type | Location | Refs | Role |

## CONVENTIONS
{ONLY deviations from standard}
## ANTI-PATTERNS (THIS PROJECT)
{Explicitly forbidden here}
## UNIQUE STYLES
{Project-specific}
## COMMANDS
```bash
{dev/test/build}
{Gotchas}
**Quality gates**: 50-150 lines, no generic advice, no obvious info.
### Subdirectory AGENTS.md (Parallel)
Launch writing tasks for each location:
for loc in AGENTS_LOCATIONS (except root):
task(category="writing", load_skills=[], run_in_background=false, description="Generate AGENTS.md", prompt= Generate AGENTS.md for: ${loc.path} - Reason: ${loc.reason} - 30-80 lines max - NEVER repeat parent content - Sections: OVERVIEW (1 line), STRUCTURE (if >5 subdirs), WHERE TO LOOK, CONVENTIONS (if different), ANTI-PATTERNS )
**Wait for all. Mark "generate" as completed.**
---
## Phase 4: Review & Deduplicate
**Mark "review" as in_progress.**
For each generated file:
- Remove generic advice
- Remove parent duplicates
- Trim to size limits
- Verify telegraphic style
**Mark "review" as completed.**

## Anti-Patterns
- **Static agent count**: MUST vary agents based on project size/depth
- **Sequential execution**: MUST parallel (explore + LSP concurrent)
- **Ignoring existing**: ALWAYS read existing first, even with --create-new
- **Over-documenting**: Not every dir needs AGENTS.md
- **Redundancy**: Child never repeats parent
- **Generic content**: Remove anything that applies to ALL projects
- **Verbose style**: Telegraphic or die
