docs: generate comprehensive CLAUDE.md reference documentation across codebase
Create a hierarchical CLAUDE.md documentation system for the entire Open Notebook
codebase with focus on concise, pattern-driven reference cards rather than
comprehensive tutorials.
## Changes
### Core Documentation System
- Updated `.claude/commands/build-claude-md.md` to distinguish between leaf and
parent modules, with special handling for prompt/template modules
- Established clear patterns:
* Leaf modules (40-70 lines): Components, hooks, API clients
* Parent modules (50-150 lines): Architecture, cross-layer patterns, data flows
* Template modules: Pattern focus, not catalog listings
### Generated Documentation
Created 15 CLAUDE.md reference files across the project:
**Frontend (React/Next.js)**
- frontend/src/CLAUDE.md: Architecture overview, data flow, three-tier design
- frontend/src/lib/hooks/CLAUDE.md: React Query patterns, state management
- frontend/src/lib/api/CLAUDE.md: Axios client, FormData handling, interceptors
- frontend/src/lib/stores/CLAUDE.md: Zustand state persistence, auth patterns
- frontend/src/components/ui/CLAUDE.md: Radix UI primitives, CVA styling
**Backend (Python/FastAPI)**
- open_notebook/CLAUDE.md: System architecture, layer interactions
- open_notebook/ai/CLAUDE.md: Model provisioning, Esperanto integration
- open_notebook/domain/CLAUDE.md: Data models, ObjectModel/RecordModel patterns
- open_notebook/database/CLAUDE.md: Repository pattern, async migrations
- open_notebook/graphs/CLAUDE.md: LangGraph workflows, async orchestration
- open_notebook/utils/CLAUDE.md: Cross-cutting utilities, context building
- open_notebook/podcasts/CLAUDE.md: Episode/speaker profiles, job tracking
**API & Other**
- api/CLAUDE.md: REST layer, service architecture
- commands/CLAUDE.md: Async command handlers, job queue patterns
- prompts/CLAUDE.md: Jinja2 templates, prompt engineering patterns (refactored)
**Project Root**
- CLAUDE.md: Project overview, three-tier architecture, tech stack, getting started
### Key Features
- Zero duplication: Parent modules reference child CLAUDE.md files, don't repeat them
- Pattern-focused: Emphasizes how components work together, not component catalogs
- Scannable: Short bullets, code examples only when necessary (1-2 per file)
- Practical: "How to extend" guides, quirks/gotchas for each module
- Navigation: Root CLAUDE.md acts as hub pointing to specialized documentation
### Cleanup
- Removed unused `batch_fix_services.py`
- Removed deprecated `open_notebook/plugins/podcasts.py`
- Updated .gitignore for documentation consistency
## Impact
New contributors can now:
1. Read root CLAUDE.md for system architecture (5 min)
2. Jump to specific layer documentation (frontend, api, open_notebook)
3. Dive into module-specific patterns in child CLAUDE.md files (1 min per module)
All documentation is lean, reference-focused, and avoids duplication.
