Create Tasks

Creates well-formed tasks that provide large amounts of contexts so that engineers that weren't in conversations can implement the task without any prior knowledge and without asking questions.

Tasks should be created using the tools and documentation conventions in the project the skills is being applied to. If the conventions are not clear, ask the user to clarify and then document them.

Task Storage

All tasks are stored in .tasks/ with the following lifecycle directories:

File naming: NNNN-short-title.md - zero-padded number, lowercase, hyphenated.

To find the next number, check across all subdirectories for the highest NNNN prefix and increment by 1.

When creating tasks, use .tasks/_template.md as the base and save them to .tasks/backlog/.

What Engineers Need

Every task must provide:

• What they're building (deliverable)
• Why it matters (context)
• Key decisions and principles they must follow
• Acceptance criteria
• Dependencies
• Related code/patterns
• How to verify it works

Before Creating Tasks: Slice First

🚨 NEVER create a task without validating its size first. A PRD deliverable is NOT automatically a task—it may be an epic that needs splitting.

Example Mapping Discovery

🚨 Never copy PRD bullets verbatim. Use Example Mapping to transform them into executable specifications.

The Examples (🟢) ARE your acceptance criteria. Write them in Given-When-Then format:

Given [context/precondition]
When [action/trigger]
Then [expected outcome]

Edge case checklist - for each rule, systematically consider:

Example: PRD says "User can search products"

Rules identified: (1) Search by title, (2) Pagination, (3) Empty state

For Rule 1 alone, edge case thinking yields:

• Given products exist → When search → Then results (happy path)
• Given no matches → When search → Then empty set
• Given empty search term → When submit → Then validation error OR all products? (🔴 Question!)
• Given special chars in search → When search → Then handled safely

Splitting Signals (Task Too Big)

If ANY of these are true, STOP and split:

• ❌ Can't describe in a specific, action-oriented title
• ❌ Would take more than 1 day
• ❌ Title requires "and" or lists multiple things
• ❌ Has multiple clusters of acceptance criteria
• ❌ Cuts horizontally (all DB, then all API, then all UI)
• ❌ PRD calls it "full implementation" or "complete system"

SPIDR Splitting Techniques

When you need to split, use these techniques:

Vertical Slices Only

Every task must be a vertical slice—cutting through all layers needed for ONE specific thing:

✅ VERTICAL (correct):
"Add search by title" → touches UI + API + DB for ONE search type

❌ HORIZONTAL (wrong):
"Build search UI" → "Build search API" → "Build search DB"

Task Naming

Formula

[Action verb] [specific object] [outcome/constraint]

Good Names

• "Add price range filter to product search"
• "Implement POST /api/users endpoint with email validation"
• "Display product recommendations on home page"
• "Enable CSV export for transaction history"
• "Validate required fields on checkout form"

Rejected Patterns

🚨 NEVER use these—they signal an epic, not a task:

If you catch yourself writing one of these, STOP and apply SPIDR.

Task Size Validation (INVEST)

Every task MUST pass INVEST before creation:

Hard Limits

• Max 1 day of work - if longer, split it
• Must be vertical - touches all layers for ONE thing
• Must be demoable - when done, you can show it working

Task Template

See .tasks/_template.md for the full template. Key sections:

---
status: backlog
created: YYYY-MM-DD
updated: YYYY-MM-DD
---

# NNNN-short-title

## Deliverable

[What user/stakeholder sees when this is done]

## Context and Motivation

[WHY this matters - PRD path, bug report URL, conversation context]

## Key Decisions

- [Decision/Principle] - [rationale]

## Acceptance Criteria

- [ ] Given [context], when [action], then [outcome]

## Out of Scope

[What this task does NOT cover]

## Dependencies

- [Dependency] - [why needed]

## Related Code

- `path/to/file` - [what pattern to follow]

## Verification

[Commands/tests that prove it works]

Process

1. Slice first - Apply Example Mapping. If task has >3-4 rules or fails splitting signals, use SPIDR to break it down.
2. Discover acceptance criteria - For each rule: generate happy path, edge cases, error cases using the checklist. Write as Given-When-Then. Surface questions.
3. Name it - Write a specific, action-oriented title. If you can't, the task isn't clear enough.
4. Validate size - Must pass INVEST. Max 1 day. Must be vertical slice.
5. Gather context (from PRD, conversation, bug report, etc.)
6. Identify key decisions that affect implementation
7. Find related code/patterns in the codebase
8. Specify verification commands
9. Output task using template

Checkpoint

Before finalizing any task, verify ALL of these:

🚨 If the PRD says "full implementation" or similar, you MUST split it. Creating such a task is a critical failure.

Session Tracking

This skill uses ${CLAUDE_SESSION_ID} to track task creation sessions:

// Each task creation is logged with session context
const sessionId = process.env.CLAUDE_SESSION_ID;
console.log(`[${sessionId}] Created task: ${taskNumber}-${taskTitle}.md`);

This allows correlation between:

• The conversation or PRD that generated the task
• The task file created in .tasks/backlog/
• Later implementation work when the task moves to in-progress/ and done/
• Task verification via task-check agent

Use the session ID to trace the full lifecycle of a task from requirements to completion.
