+# Lookup: Task CLI Commands
+
+**Purpose**: Quick reference for task-cli.ts commands
+
+**Last Updated**: 2026-02-14
+
+---
+
+## Usage
+
+```bash
+bunx --bun ts-node .opencode/context/tasks/scripts/task-cli.ts <command> [args]
+```
+
+Task files are stored in `.tmp/tasks/` at the project root.
+
+---
+
+## Commands
+
+### status [feature]
+
+Show task status summary for all features or specific feature.
+
+```bash
+task-cli.ts status
+task-cli.ts status my-feature
+```
+
+**Output**:
+```
+[my-feature] My Feature Name
+  Status: active | Progress: 40% (2/5)
+  Pending: 2 | In Progress: 1 | Completed: 2 | Blocked: 0
+```
+
+---
+
+### next [feature]
+
+Show tasks ready to work on (deps satisfied).
+
+```bash
+task-cli.ts next
+task-cli.ts next my-feature
+```
+
+**Output**:
+```
+=== Ready Tasks (deps satisfied) ===
+
+[my-feature]
+  02 - Create JWT service  [sequential]
+  03 - Write unit tests    [parallel]
+```
+
+---
+
+### parallel [feature]
+
+Show only parallelizable tasks ready now.
+
+```bash
+task-cli.ts parallel
+task-cli.ts parallel my-feature
+```
+
+**Use**: Batch multiple isolated tasks for parallel execution.
+
+---
+
+### deps \<feature\> \<seq\>
+
+Show dependency tree for a specific task.
+
+```bash
+task-cli.ts deps my-feature 04
+```
+
+**Output**:
+```
+=== Dependency Tree: my-feature/04 ===
+
+04 - Integration tests [pending]
+  ├── ✓ 01 - Setup database [completed]
+  └── ○ 02 - Create API [pending]
+      └── ✓ 01 - Setup database [completed]
+```
+
+---
+
+### blocked [feature]
+
+Show blocked tasks and reasons.
+
+```bash
+task-cli.ts blocked
+task-cli.ts blocked my-feature
+```
+
+**Output**:
+```
+=== Blocked Tasks ===
+
+[my-feature]
+  04 - Integration tests (waiting: 02, 03)
+  05 - Deploy (explicitly blocked)
+```
+
+---
+
+### complete \<feature\> \<seq\> "summary"
+
+Mark task as completed with summary (max 200 chars).
+
+```bash
+task-cli.ts complete my-feature 02 "Created JWT service with RS256 signing"
+```
+
+**Effect**:
+- Sets `status: "completed"`
+- Sets `completed_at` timestamp
+- Sets `completion_summary`
+- Updates `task.json` counts
+
+---
+
+### validate [feature]
+
+Check JSON validity, dependencies, circular refs.
+
+```bash
+task-cli.ts validate
+task-cli.ts validate my-feature
+```
+
+**Checks**:
+- task.json exists
+- ID format correct
+- Dependencies exist
+- No circular dependencies
+- Counts match
+
+**Output**:
+```
+[my-feature]
+  ✓ All checks passed
+
+[broken-feature]
+  ✗ ERROR: 03: depends on non-existent task 99
+  ⚠ WARNING: 02: No acceptance criteria defined
+```
+
+---
+
+## Exit Codes
+
+| Code | Meaning |
+|------|---------|
+| 0 | Success |
+| 1 | Error (validate found issues, missing args) |
+
+---
+
+## Enhanced Schema Support
+
+The CLI fully supports the enhanced task schema (v2.0) with:
+- **Line-number precision** - Context files with specific line ranges
+- **Domain modeling** - bounded_context, module, vertical_slice fields
+- **Contract tracking** - API/interface dependencies
+- **Design artifacts** - Figma, wireframes, mockups
+- **ADR references** - Architecture decision records
+- **Prioritization** - RICE/WSJF scores
+
+All enhanced fields are optional and backward compatible. See `../standards/enhanced-task-schema.md` for details.
+
+---
+
+## Planning Workflow Integration
+
+For multi-stage orchestration workflows, use these planning agents before task creation:
+
+| Agent | Purpose | Output |
+|-------|---------|--------|
+| **ArchitectureAnalyzer** | DDD bounded context identification | `.tmp/architecture/contexts.json` |
+| **StoryMapper** | User journey and story mapping | `.tmp/story-maps/map.json` |
+| **PrioritizationEngine** | RICE/WSJF scoring | `.tmp/backlog/prioritized.json` |
+| **ContractManager** | API contract definition | `.tmp/contracts/{service}.json` |
+| **ADRManager** | Architecture decision records | `docs/adr/` |
+
+These agents populate enhanced schema fields (bounded_context, contracts, related_adrs, rice_score, etc.) automatically.
+
+See `.opencode/context/core/workflows/multi-stage-orchestration.md` for the complete workflow.
