Created plugin directory structure:
- plugin.json manifest (v0.1.0)
- hooks/ directory with __init__.py
- skills/ directories for 4 skills:
  * blog-session-manager
  * blog-note-capture
  * blog-draft-composer
  * blog-image-manager

All Phase 1 tasks (1.1-1.7) complete.
Status: Ready for Phase 2 (State Management)

… storage discovery

Phase 2.1 Complete:
- Created state.py with ensure_blog_dir() utility
- Handles first-run gracefully with Path.mkdir(exist_ok=True)

Critical Discovery:
- Assistant messages ARE persisted in session files
- Two separate storage systems:
  * Transcripts (~/.claude/transcripts/): tool interactions only
  * Session files (~/.claude/projects/): full conversation with assistant
- Session files only created when persistence enabled (not with --no-session-persistence)

Updated documentation with findings.
Next: Phase 2.2-2.9 (state management)

Task 2.2 complete:
- Added BlogMetadata TypedDict with 5 fields (title, created_at, status, transcript_path, session_path)
- Added BlogState TypedDict with 2 fields (next_sequence_id, blogs)
- Type-safe schema for state.json
- Verified imports work correctly

Investigation update:
- Confirmed transcript exists for current session
- Session file (with assistant messages) not created yet
- Unknown if written during session or at SessionEnd

- Removed deprecated skill_forced_eval.sh command
- Updated to use user_prompt_submit.py for improved logging functionality

Task 2.3 complete:
- Implemented read_state() - returns BlogState, creates default {next_sequence_id: 1, blogs: {}} on first-run
- Implemented write_state() - uses atomic write (tempfile + os.replace) to prevent corruption
- Handles JSON parse errors gracefully (returns default state)
- Uses lazy imports to avoid linting warnings
- All tests pass: default creation, write/read cycle

Pattern verified: tempfile in .blog/ dir + os.replace() for atomic semantics

Progress: 17/123 tasks (14%)

Task 2.4 complete:
- backup_state() creates timestamped backups (state.json.bak.YYYYMMDD_HHMMSS)
- restore_state() finds most recent backup and restores atomically
- Uses shutil.copy2 to preserve metadata
- Returns True/False for restore success
- All tests pass

Progress: 18/123 tasks (15%)

Tasks 2.5-2.9 complete (combined for efficiency):
- create_blog_dir(blog_id) - Creates .blog/{blog_id}/ with subdirs
- get_next_sequence_id() - Returns current sequence number
- increment_sequence_id() - Atomically increments sequence
- add_blog_to_state(blog_id, metadata) - Adds blog entry
- update_blog_status(blog_id, status) - Updates blog status

All functions:
- Use atomic operations via read_state/write_state
- Have comprehensive docstrings and type hints
- Tested and verified independently

- Added SessionStart hook registration to plugin.json
- Hook path: ./hooks/session_start.py

✅ Phase 3 COMPLETE: SessionStart Hook (4/4 tasks)
Progress: 27/123 tasks (22%)

- Generates unique blog_id with timestamp format
- Creates blog directory structure (notes/, transcripts/, drafts/)
- Adds placeholder metadata to state.json

Tested and verified:
- Trigger detection works correctly
- Blog directories created with proper structure

Remaining Phase 4: Tasks 4.5-4.6 (session_id handling, title extraction)

Progress: 31/123 tasks (25%)

Tasks 4.5-4.6 complete:
- Extract session_id from stdin JSON (supports sessionId and session_id keys)
- Intelligent title extraction from prompt:
  * Strips #blog and trigger keywords
  * Extracts first sentence (stops at . ? !)
  * Falls back to first 50 chars
  * Capitalizes first letter
- Updated BlogMetadata TypedDict with session_id and extracted_title fields
- All tests pass

✅ Phase 4 COMPLETE: UserPromptSubmit Hook (6/6 tasks)

- Update plugin.json to reference hooks/hooks.json
- Delete settings.json (replaced by hooks/hooks.json)
- Update README.md with new directory structure
- Add .blog/ to gitignore for test data

Standard plugin layout:
  .claude-plugin/plugin.json  # Plugin manifest
  hooks/hooks.json            # Hook config (event → command)
  scripts/                    # Hook implementation scripts

- Move plugins from .claude-plugin/plugins/ to repo root plugins/

This directory contains local workflow tracking that shouldn't be shared.

…JECT_DIR

- Remove AI CLI invocation from hooks (Claude handles AI work now)
- Delete utils/ai.py - no longer needed
- Simplify hooks to silent operation:
  - session_start: just initializes .blog/ directory
  - stop: silently captures transcript if blog active
  - session_end: silently updates blog status
- user_prompt_submit: #blog starts tracking, 'stop tracking' ends
- Use CLAUDE_PROJECT_DIR env var for .blog/ location
- Clean up verbose docstrings throughout
