Breaks features into atomic, independently verifiable tasks. No task should take more than 4 hours. Unblocks parallel work and reduces integration risk.

Overview

Large tasks fail in large ways. Decomposed tasks fail in small, fixable ways. This skill breaks any feature or project into atomic tasks — each independently implementable, testable, and deployable.

When to Use

Before starting any feature that takes more than half a day
When a task feels overwhelming or unclear
When multiple people need to work in parallel

Process

Step 1: Identify the Deliverable

State what "done" looks like for the whole feature.
List all the things that must be true when it's complete.
Identify dependencies: what must exist before any task can start?

Verify: You can state the full feature goal in 2 sentences.

Step 2: Decompose Into Atomic Tasks

Break the feature into tasks where each task:
- Can be completed in under 4 hours
- Has a single, clear output
- Can be verified independently
- Can be reverted without breaking other tasks
Each task should be: [verb] [noun] so that [outcome]
- ✅ "Add rate limiting to /api/login so that brute-force is prevented"
- ❌ "Work on the login security stuff"

Verify: Every task is under 4 hours. Every task has a clear verify condition.

Step 3: Order and Parallelism

Draw the dependency graph — what blocks what?
Identify tasks that can be done in parallel.
Sequence tasks so integration happens incrementally (not as one big bang at the end).

Verify: The dependency order is clear. No unnecessary sequential dependencies.

Step 4: Estimate and Adjust

For each task, estimate: best case / worst case / expected.
If any task's worst case > 1 day: decompose further.
Total estimate sanity check: does it add up to a reasonable timeline?

Common Rationalizations (and Rebuttals)

Excuse	Rebuttal
"I'll figure it out as I go"	Decomposition takes 30 minutes. Rework from poor planning takes days.
"It's too complex to break down"	Everything can be decomposed. Start with what you know, decompose the rest later.
"The tasks are too granular"	Granular tasks ship continuously. Coarse tasks ship never.

Verification

Each task is under 4 hours
Each task has a single verify condition
Dependencies mapped — no circular dependencies
Parallel work identified
