Write Atomic Tasks

Quick Start

Transform vague task descriptions into precise, autonomous-execution-ready specifications:

❌ BEFORE (vague):
- [ ] Add error handling

✅ AFTER (precise):
- [ ] Task 1: Add ConnectionError and TimeoutError handling to ClaudeAgentClient.query()
      - Retry 3 times with exponential backoff (1s, 2s, 4s)
      - Raise AgentConnectionError after retries exhausted
      - Location: src/temet_run/agent/client.py:ClaudeAgentClient.query
      - Verify: pytest tests/unit/agent/test_client.py passes

When to Use This Skill

Explicit Triggers:

• "Write a task for..."
• "Create todo items for..."
• "Break down this feature into tasks"
• "Make this task more precise"
• "How should I write this as a task?"

Implicit Triggers:

• Task description lacks file paths
• No verification command specified
• Vague action verbs ("fix", "add", "update" without specifics)
• Missing success criteria
• Task would require clarifying questions before starting

Debugging/Quality Scenarios:

• Reviewing task list for autonomous execution readiness
• Agent keeps asking clarifying questions about tasks
• Tasks take longer than expected due to ambiguity
• Post-mortem reveals task interpretation issues

What This Skill Does

This skill transforms vague task descriptions into precise, autonomous-execution-ready specifications by:

1. Applying SMART+ Framework - Ensuring every task is Specific, Measurable, Actionable, Referenced, Testable, with Context
2. Adding Critical Metadata - File paths, verification commands, success criteria
3. Decomposing Large Work - Breaking complex tasks into 30-minute chunks
4. Eliminating Vague Patterns - Replacing forbidden phrases with precise alternatives
5. Validating Precision - Checking that tasks answer all 6 precision questions

The SMART+ Framework

Every task MUST include these components:

Task Template

- [ ] Task N: [ACTION VERB] [SPECIFIC TARGET] [SUCCESS CRITERIA]
      Location: [file paths or module names]
      Verify: [how to confirm completion]

Complete Example:

- [ ] Task 1: Add ConversationError exception hierarchy to agent/errors.py
      - Create: ConversationError(base), MessageError, StateError
      - Location: src/temet_run/agent/errors.py
      - Verify: mypy passes, errors importable from temet_run.agent

Precision Checklist

Before writing a task, verify it answers ALL these questions:

1. ✅ WHAT file(s)? → Include full path from project root
2. ✅ WHAT function/class? → Name the specific target
3. ✅ WHAT action? → Use precise verbs: Create, Add, Modify, Remove, Rename, Extract, Move
4. ✅ WHAT inputs/outputs? → Specify types, fields, parameters
5. ✅ HOW to verify? → Command to run: pytest path, mypy src/, uv run temet-run ...
6. ✅ WHY doing this? → Link to ADR, issue, or parent task (optional but helpful)

Forbidden Vague Patterns

NEVER write tasks containing these vague phrases:

Task Decomposition Rules

Large tasks MUST be broken down:

1. One concern per task - Don't mix "create model AND write tests AND add CLI"
2. Max 30 minutes of work - If longer, split it
3. Dependencies explicit - "Task 3 depends on Task 2" or use sub-numbering (2.1, 2.2)
4. Verification per task - Each task independently verifiable

Decomposition Example:

## Feature: Add conversation history command

- [ ] Task 1: Create ConversationRepository protocol
      Location: src/temet_run/domain/repositories.py
      Verify: mypy passes

- [ ] Task 2: Implement JsonlConversationRepository
      Location: src/temet_run/infrastructure/repositories/conversation.py
      Verify: Unit tests pass (create tests/unit/infrastructure/test_conversation_repo.py)

- [ ] Task 3: Add `history` subcommand to CLI
      Location: src/temet_run/main.py (add to agents group)
      Verify: `uv run temet-run agents history --help` shows usage

- [ ] Task 4: Integration test for history command
      Location: tests/integration/test_cli_history.py
      Verify: pytest tests/integration/test_cli_history.py passes

Examples: Vague → Precise Transformation

See examples/transformation-examples.md for comprehensive examples covering:

• Error handling tasks
• Data model implementation
• Test writing tasks
• Bug fixes
• Feature additions
• Refactoring work

Inline Example:

❌ VAGUE:
- [ ] Add error handling to the client

✅ PRECISE:
- [ ] Add ConnectionError and TimeoutError handling to ClaudeAgentClient.query()
      - Retry 3 times with exponential backoff (1s, 2s, 4s)
      - Raise AgentConnectionError after retries exhausted
      - Location: src/temet_run/agent/client.py:ClaudeAgentClient.query
      - Verify: pytest tests/unit/agent/test_client.py passes

Validation Process

To validate a task for precision:

1. Read the task description
2. Apply the 6-question checklist (Section 5)
3. Check for forbidden vague patterns (Section 6)
4. Verify SMART+ components present (Section 3)
5. Confirm task is <30 minutes of work

Validation Script (if available):

python ~/.claude/skills/write-atomic-tasks/scripts/validate_task.py "task description"

Manual Validation Output:

Task: "Add error handling to the client"

❌ FAILED Precision Check:
- Missing: Specific file path
- Missing: Function/class name
- Missing: Verification command
- Vague pattern: "Add error handling" (see Section 6)

Suggested rewrite:
- [ ] Add ConnectionError handling to ClaudeAgentClient.query()
      Location: src/temet_run/agent/client.py:ClaudeAgentClient.query
      Verify: pytest tests/unit/agent/test_client.py passes

Expected Outcomes

Successful Task Writing

When tasks are written with this skill:

✅ Agents can execute autonomously - No clarifying questions needed ✅ Clear verification - Unambiguous success/failure determination ✅ Predictable effort - Tasks complete in <30 minutes ✅ Reduced rework - Fewer interpretation errors ✅ Better planning - Accurate time estimates from precise scoping

Before/After Metrics

Requirements

Knowledge:

• Understanding of SMART goal framework
• Familiarity with project file structure
• Awareness of verification commands (pytest, mypy, etc.)

Tools:

• None (skill is language/framework agnostic)

Environment:

• Works with any task management system
• Compatible with todo.md, Jira, GitHub Issues, etc.

Red Flags to Avoid

Red Flags Checklist:

• ❌ Task description fits on one line but has no metadata
• ❌ No file path mentioned
• ❌ Action verb is generic ("fix", "update", "add")
• ❌ No verification command provided
• ❌ Success criteria is subjective ("make it better")
• ❌ Task mixes multiple concerns (AND, THEN, ALSO in description)
• ❌ Task would take >30 minutes but isn't decomposed
• ❌ Contains forbidden vague patterns (Section 6)
• ❌ Missing inputs/outputs specification for data operations
• ❌ No link to parent task/ADR/issue for context

Common Mistakes:

1. Too granular - "Add import statement" is usually too small, combine with actual work
2. Too high-level - "Implement authentication" needs 10+ subtasks
3. Technology assumption - "Add React component" when framework not decided
4. Implicit dependencies - "Write tests" assumes code exists, make dependency explicit

Notes

• This skill is framework-agnostic - Works for any programming language or project type
• Precision scales with task complexity - Simple tasks need less metadata than complex ones
• Context determines precision level - Solo developer vs distributed team changes requirements
• Tasks are living documents - Update tasks when requirements change, don't let them drift
• Autonomous execution is the goal - If a task requires synchronous communication, it's not precise enough
