v0.3.0 — Task Dependencies, PWA, Skills, Hooks

What's New

Task Dependencies (DAG)

• blocked_by / blocks relationships between tasks
• Database-level cycle detection via recursive CTE
• Atomic creation: add_task with blocked_by parameter creates task + edges in one transaction
• get_tasks and get_top_tasks return blocked_by array in compact output

Session-to-Task Linking

• session_id column tracks which Claude session worked on each task
• Enables "what did this session accomplish?" queries and cross-session resume

Mobile PWA

• Web app manifest, service worker (Workbox), responsive mobile UI
• Task card view for mobile, full-screen modals, sticky mobile header
• IndexedDB-backed offline mutation queue with auto-sync on reconnect
• Install prompt banner and network status indicator

Context-Fence Skill Pair

• writbase-router (68 lines): lightweight intent classifier loaded in main context
• writbase-recipes (418 lines, context:fork): dense API reference in isolated subagent
• ~87% token savings vs loading worker + manager skills inline

/loop Skill

• Autonomous task processing: poll → claim → execute → complete → loop
• Circuit breaker (3 consecutive errors), version conflict retry
• Writes .claude/current-task.json for hook integration

Audit Trail Hook

• PostToolUse hook captures git commit SHAs and PR URLs as task provenance
• Reads active task from .claude/current-task.json

Agent Teams Hook Sync

• SubagentStop hook auto-marks WritBase tasks done when subagents complete
• Parses response version from transcript (not input version)

Agent Stop Hook (via writbase init)

• writbase init now installs an agent-type Stop hook to ~/.claude/settings.json
• Blocks session end when WritBase tools were used but no tasks were tracked
• Idempotent — safe to re-run

Breaking Changes

• worker and manager skills removed (superseded by context-fence recipes)
• Plugin now registers 4 skills: extract-tasks, loop, writbase-router, writbase-recipes

Migrations

• 00029_session_id.sql — adds session_id column to tasks
• 00030_task_dependencies.sql — adds task_dependencies table, cycle detection, updated RPCs

Run npx writbase init to upgrade.
