PairCoder Task Lifecycle

Decision Tree: Which Command to Use?

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

Rule of thumb: If you see TRELLO-XX IDs, use ttask. If you only have TASK-XXX IDs, use task update.

CRITICAL: Always Use CLI Commands

Task state changes MUST go through the CLI to trigger hooks (Trello sync, timers, state updates).

Never just edit task files or say "marking as done" - run the command.

Automatic Hooks

When you change task status via CLI, these hooks fire automatically:

On task update --status in_progress:

• start_timer - Begins time tracking
• sync_trello - Moves card to "In Progress"
• update_state - Updates state.md current focus

On task update --status done:

• 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

On task update --status blocked:

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

You don't need to manually update Trello, start/stop timers, or refresh state.md - hooks handle it.

Starting a Task

bpsai-pair task update TASK-XXX --status in_progress

This will:

• Update task file status
• Move Trello card to "In Progress" list
• Start timer (when implemented)
• Update state.md current focus

During Work (Progress Updates)

bpsai-pair ttask comment TASK-XXX "Completed API endpoints, starting tests"

This adds a comment to the Trello card without changing status. Use for:

• Milestone updates
• Noting decisions
• Progress visibility for team

Completing a Task

For Trello Projects (Recommended)

Use ttask done - it handles everything in one command:

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

This single command will:

• ✓ Move Trello card to "Deployed/Done" list
• ✓ Auto-check ALL acceptance criteria items
• ✓ Add completion summary to card
• ✓ Update local task file status
• ✓ Trigger all completion hooks (timer, metrics, state.md)

You do NOT need to also run task update --status done - ttask done handles it.

For Non-Trello Projects

Use task update:

bpsai-pair task update TASK-XXX --status done

This will:

• Update task file status
• Trigger completion hooks (timer, metrics, state.md)

Common Mistakes

Mistake	Why It's Wrong	Correct Approach
Using only task update on Trello projects	Doesn't check AC on Trello card	Use ttask done instead
Using both commands on Trello projects	Unnecessary duplication	Just use ttask done
Using ttask on non-Trello projects	Commands won't work	Use task update

Quick Reference

Local Task Commands (task)

Use these for status changes - they trigger all hooks.

Action	Command
Start task	bpsai-pair task update TASK-XXX --status in_progress
Complete task	bpsai-pair task update TASK-XXX --status done
Block task	bpsai-pair task update TASK-XXX --status blocked
Show next task	bpsai-pair task next
Auto-assign next	bpsai-pair task auto-next
List all tasks	bpsai-pair task list
Show task details	bpsai-pair task show TASK-XXX

Trello Card Commands (ttask)

Use these for direct Trello operations.

Action	Command
List Trello cards	bpsai-pair ttask list
Show card details	bpsai-pair ttask show TRELLO-XX
Start card	bpsai-pair ttask start TRELLO-XX
Complete card	bpsai-pair ttask done TRELLO-XX --summary "..." --list "Deployed/Done"
Check acceptance item	bpsai-pair ttask check TRELLO-XX "item text"
Add progress comment	bpsai-pair ttask comment TRELLO-XX "message"
Block card	bpsai-pair ttask block TRELLO-XX --reason "why"
Move card to list	bpsai-pair ttask move TRELLO-XX "List Name"

When to Use task vs ttask

For Trello-connected projects (preferred):

Scenario	Command
Starting a task	ttask start TRELLO-XX
Progress updates	ttask comment TRELLO-XX "message"
Completing a task	ttask done TRELLO-XX --summary "..." --list "Deployed/Done"
Blocking a task	ttask block TRELLO-XX --reason "..."

For non-Trello projects:

Scenario	Command
Starting a task	task update TASK-XXX --status in_progress
Completing a task	task update TASK-XXX --status done
Blocking a task	task update TASK-XXX --status blocked

Key insight: ttask commands handle both Trello AND local state. You don't need to run task update after ttask done - it handles everything.

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

Workflow Checklist

When Starting a Task

1. Run: bpsai-pair task update TASK-XXX --status in_progress
2. Verify Trello card moved
3. Read the task file for implementation plan
4. Begin work

During Work

1. Add progress comments: bpsai-pair ttask comment TASK-XXX "status update"
2. Commit frequently with task ID in message

When Completing a Task

For Trello projects:

1. Ensure tests pass: pytest -v
2. Find card ID: bpsai-pair ttask list
3. Complete: bpsai-pair ttask done TRELLO-XX --summary "..." --list "Deployed/Done"
4. Update state.md with what was done
5. Commit changes with task ID in message

For non-Trello projects:

1. Ensure tests pass: pytest -v
2. Complete: bpsai-pair task update TASK-XXX --status done
3. Update state.md with what was done
4. Commit changes with task ID in message

Validation Scripts

Use these scripts to validate before completion:

Validate Task File Format

python .claude/skills/managing-task-lifecycle/scripts/validate_task_status.py TASK-XXX

Checks: frontmatter, required fields, valid status, acceptance criteria section.

Check Completion Readiness

python .claude/skills/managing-task-lifecycle/scripts/check_completion.py TASK-XXX

Runs: task file validation, tests, linting, git status.

Validation loop: Run → fix issues → re-run until all checks pass.

Trello Sync Commands

# Check Trello connection status
bpsai-pair trello status

# Sync plan to Trello (creates/updates cards)
bpsai-pair plan sync-trello PLAN-ID

# Force refresh from Trello
bpsai-pair trello refresh
