Task Lifecycle Management

When to Use

• Starting work on a task
• Completing a task with verification
• Blocking a task with reason
• Transitioning task status
• Progress updates during work

Decision Tree: Which Command?

Is Trello connected? (check: bpsai-pair trello status)
│
├── YES → Use `ttask` commands (primary)
│   ├── Start:    bpsai-pair ttask start TRELLO-XX
│   ├── Complete: bpsai-pair ttask done TRELLO-XX --summary "..." --list "Deployed/Done"
│   └── Block:    bpsai-pair ttask block TRELLO-XX --reason "..."
│
└── NO → Use `task update` commands
    ├── Start:    bpsai-pair task update TASK-XXX --status in_progress
    ├── Complete: bpsai-pair task update TASK-XXX --status done
    └── Block:    bpsai-pair task update TASK-XXX --status blocked

---

Starting a Task (Driver Role)

Pre-Flight Checks

Before starting work, verify everything is ready:

# Check budget for this task
bpsai-pair budget check <task-id>
# Example : bpsai-pair budget check T1.13

# Verify task exists and get details
bpsai-pair task show <task-id>

# Check for blockers (dependencies)
bpsai-pair task list --status blocked

Budget Warning: If budget check warns, inform user of token estimate and ask to proceed.

Task Not Found: Check if it's a Trello ID (TRELLO-XXX) vs local ID (T1.1).

Start the Task

# Start locally (triggers hooks)
bpsai-pair task update <task-id> --status in_progress

# If Trello card exists, start there too
bpsai-pair ttask start TRELLO-XX

Read Task Requirements

cat .paircoder/tasks/*/<task-id>.task.md
# or
bpsai-pair task show <task-id>

Identify ALL acceptance criteria - these MUST be completed before marking done.

Automatic Hooks on Start

When you start via CLI, these fire automatically:

• start_timer - Begins time tracking
• sync_trello - Moves card to "In Progress"
• update_state - Updates state.md current focus
• check_token_budget - Warns if task exceeds budget

---

During Work

Follow TDD Approach (See also: implementing-with-tdd skill for additional workflow requirements.)

1. Red: Write failing test for the requirement
2. Green: Write minimal code to pass
3. Refactor: Clean up while keeping tests green

# Run tests frequently
pytest tests/ -x --tb=short

# Or for specific test file
pytest tests/test_<module>.py -v

Follow Wheel-and-spoke Approach (See also: architecting-modules skill for file size limits and decomposition patterns.)

Track Progress

Add progress comments without changing status:

bpsai-pair ttask comment TRELLO-XX "Completed API endpoints, starting tests"

Use for:

• Milestone updates
• Noting decisions
• Progress visibility for team

Check Off Acceptance Criteria

As you complete each criterion:

bpsai-pair ttask check TRELLO-XX "<acceptance criterion text>"

---

Pre-Completion Verification (ENFORCEMENT GATE)

CRITICAL: Before marking task complete, ALL gates must pass.

Run Tests

# Full test suite must pass
pytest tests/ --tb=short

# Check coverage if required
pytest tests/ --cov --cov-report=term-missing

Verify Acceptance Criteria

# Check what's still unchecked on Trello
bpsai-pair ttask show TRELLO-XX

If ANY acceptance criteria are unchecked, complete them before proceeding.

Self-Review Checklist

Before completing, verify:

• All acceptance criteria addressed
• Tests pass
• No obvious bugs or TODOs left
• Code follows project conventions

---

Completing a Task

For Trello Projects (Recommended)

Use ttask done with --strict flag (enforcement gate):

bpsai-pair ttask done TRELLO-XX --strict --summary "What was accomplished" --list "Deployed/Done"

This single command will:

• ✓ Verify ALL acceptance criteria are checked (strict mode)
• ✓ Move Trello card to "Deployed/Done" list
• ✓ Add completion summary to card
• ✓ Update local task file status
• ✓ Trigger all completion hooks

If --strict fails: You have unchecked acceptance criteria. Go back and complete them.

NEVER use --force unless explicitly instructed by user. Forced completions are logged to .paircoder/history/bypass_log.jsonl.

For Non-Trello Projects

bpsai-pair task update <task-id> --status done

Common Mistakes

Mistake	Why Wrong	Correct
task update only on Trello projects	Doesn't check AC	Use ttask done
Both commands on Trello projects	Duplication	Just ttask done
ttask on non-Trello projects	Won't work	Use task update
Skipping --strict	No enforcement	Always use --strict

---

Post-Completion (NON-NEGOTIABLE)

Update State

You MUST update state.md after completing any task.

bpsai-pair context-sync \
    --last "<task-id>: <brief description of what was accomplished>" \
    --next "<next task ID or 'Ready for next task'>"

Or manually edit .paircoder/context/state.md:

• Add entry under "What Was Just Done"
• Update "What's Next"
• Mark task as done in any task lists

Report Completion

✅ **Task Complete**: <task-id>

**Summary**: <what was accomplished>
**Time**: <actual time if tracked>
**Tests**: All passing
**Acceptance Criteria**: All verified ✓

**Files Changed**:
- path/to/file1.py
- path/to/file2.py

**Next Task**: <next task ID> or "Sprint complete!"

Automatic Hooks on Complete

These fire automatically:

• stop_timer - Stops timer, records duration
• record_metrics - Records token usage and costs
• record_velocity - Tracks sprint velocity
• sync_trello - Moves card to "Deployed/Done"
• update_state - Updates state.md
• check_unblocked - Identifies newly unblocked tasks

---

Blocking a Task

When a task cannot proceed:

# With Trello
bpsai-pair ttask block TRELLO-XX --reason "Waiting for API documentation"

# Without Trello
bpsai-pair task update <task-id> --status blocked

Hooks fired:

• sync_trello - Moves card to "Issues/Tech Debt"
• update_state - Updates state.md

---

Error Recovery

Tests Fail During Completion

1. Fix the failing tests
2. Re-run verification
3. Then complete

AC Verification Fails (--strict blocks)

1. Check which items unchecked: bpsai-pair ttask show TRELLO-XX
2. Complete the missing work
3. Check off items: bpsai-pair ttask check TRELLO-XX "<item>"
4. Retry completion

Force Completion (LAST RESORT)

# This logs a bypass - only with explicit user approval
bpsai-pair ttask done TRELLO-XX --force --summary "<summary>"

Bypasses are logged to .paircoder/history/bypass_log.jsonl for audit.

Task ID Formats

Format	Example	Use For
Sprint task	T1.1	bpsai-pair task commands
Legacy	TASK-150	bpsai-pair task commands
Trello	TRELLO-abc123	bpsai-pair ttask commands

---

Task Status Values

Status	Meaning	Trello List
pending	Not started	Backlog / Planned
in_progress	Currently working	In Progress
blocked	Waiting on something	Issues / Blocked
review	Ready for review	Review
done	Completed	Deployed / Done

---

Task Readiness (on_task_ready Hook)

Tasks automatically transition from Intake/Backlog to Planned/Ready when they meet readiness criteria:

Readiness Criteria:

1. Has a title (non-empty)
2. Has a plan assigned (plan_id set)
3. Has acceptance criteria (markdown checklist items: - [ ] in body)
4. Status is "pending"

Triggered By:

• plan sync-trello command (fires on_task_ready hooks by default)
• Skip with --no-fire-ready flag

What Happens:

• sync_trello hook moves card from Intake/Backlog to Planned/Ready
• update_state hook updates state.md

Enforcement: Tasks without acceptance criteria should NOT be started. Ensure AC exists before beginning work.

• NEVER mark task complete without updating state.md
• NEVER use --force without explicit user approval
• Forced bypasses are logged for audit
• Checkpoints created automatically on task start (if hooks enabled)
