Break down epics and features into concrete backlog tasks with dependencies. Use when planning work, decomposing large features, or organizing sprints. Trigger with "break down", "decompose", "plan feature", "create subtasks".

Review code changes with parallel detection agents and smart fixing
Branch merging and conflict resolution patterns. Use when merging feature branches, handling conflicts, or cleaning up worktrees. Trigger with "merge branch", "resolve conflicts", "cleanup worktree".
Controls Chrome browser: takes screenshots, clicks buttons, fills forms, downloads images, inspects pages, captures network requests, checks console errors, debugs API issues. Use when: 'screenshot', 'click', 'fill form', 'download image', 'check browser', 'look at screen', 'capture page', 'check for errors', 'debug network', 'API failing', 'console errors'. Provides MCP tool discovery for 70 tabz_* browser automation tools.
Brainstorm ideas and design workflows with a beads expert. Use when: 'help me plan', 'how should I structure this', 'what beads features', 'brainstorm', 'before I create tasks', 'design my workflow'. For ideation BEFORE creating issues.
Docs/changelog checkpoint. Detects whether changes are user-facing and ensures documentation hygiene (CHANGELOG + lessons-learned) is handled or explicitly bypassed. Use when: 'docs check', 'changelog', 'release notes', 'did we update docs?'.

Patterns for breaking down large features into concrete, parallelizable tasks.
1. Infrastructure
└── Types, contexts, schemas, state management
2. Core Implementation
└── Main components, business logic
3. Integration
└── Connect pieces, wire up routes
4. Polish
└── Edge cases, error handling, UX improvements
5. Validation
└── Tests, documentation updates
Example: Dark Mode
1. Create New
└── Build new pattern alongside old
2. Migrate
└── Move components one at a time
3. Cleanup
└── Remove old pattern, dead code
4. Verify
└── Update tests, ensure no regressions
Example: Move to React Query
1. Investigate (if complex)
└── Reproduce, identify root cause
2. Fix
└── Implement the solution
3. Verify
└── Add regression test
Most bugs don't need decomposition - only create subtasks for complex bugs requiring investigation.
| Size | Lines Changed | Files | Time | Example |
|---|---|---|---|---|
| XS | <20 | 1 | Minutes | Fix typo, add import |
| S | 20-100 | 1-2 | <1hr | Add helper function |
| M | 100-300 | 2-5 | Hours | Add component |
| L | 300+ | 5+ | Day | Feature module |
| XL | 1000+ | 10+ | Days | Architecture change |
Target: S-M tasks. XS is too granular, L-XL should be broken down.
A: Create database schema
B: Implement API endpoint (blocked by A)
C: Add frontend form (blocked by B)
A: Create shared context
B: Use in Header (blocked by A)
C: Use in Footer (blocked by A)
D: Use in Sidebar (blocked by A)
B, C, D: Independent features
E: Integration testing (blocked by B, C, D)
B: Update styles.css for Header
C: Update styles.css for Footer (blocked by B)
Even though B and C are conceptually parallel, they touch the same file.
Common conflict points:
styles.css, theme.ts)routes.tsx, App.tsx)store.ts, context.tsx)types.ts, interfaces.ts)testUtils.ts, fixtures.ts)When detected: Add dependency between tasks to sequence them.
Group tasks into waves:
## Wave 1 (Ready Now)
Tasks with no blockers - start immediately
## Wave 2 (After Wave 1)
Tasks blocked by Wave 1 - becomes ready when Wave 1 completes
## Wave 3 (After Wave 2)
Final integration, polish tasks
Max 3-5 tasks per wave for manageability.
