What it does

Task Decomposition is an agent skill from rohitg00/skillkit. Breaks down complex software, writing, or research tasks into small, atomic, independently completable units with dependency graphs and milestone breakdowns. Use when the user asks to plan a project, decompose a feature, create subtasks, split up work, or needs help organizing a large piece of work into a step-by-step plan. Triggered by phrases like "break down", "decompose", "where do I start", "too big", "split into tasks", "work breakdown", or "task list".

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Agent Workflows, covering Task breakdown. The repository describes itself as: Supercharge AI coding agents with portable skills. Install, translate & share skills across Claude Code, Cursor, Codex, Copilot & 40 more. The licence is Apache-2.0.

When your agent uses it

  • The user asks to plan a project
  • Decompose a feature
  • Create subtasks
  • Needs help organizing a large piece of work into a step-by-step plan

Example prompts

  • “break down”
  • “decompose”
  • “where do I start”
  • “/task-decomposition”

Workflow steps

4 steps, taken from the step headings in SKILL.md.

  1. Vertical Slicing
  2. Horizontal Layering
  3. Workflow Decomposition
  4. Component Decomposition

What it can do on your machine

Read from SKILL.md and the folder at commit d2e5c34. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Task Decomposition loads about 1.2k tokens when it runs. Until then it costs about 121 tokens; SKILL.md has 210 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~121
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Task Decomposition

You are breaking down a complex task into smaller, atomic units. Each unit should be independently completable and verifiable.

Core Principle

If a task feels too big, it is too big. Break it down until each piece is obvious.

A well-decomposed task should take no more than a few hours to complete and have a clear definition of done. Aim for tasks that are small, independent, testable, and clearly scoped.

Decomposition Techniques

1. Vertical Slicing

Break by user-visible functionality (each slice is deployable and testable independently):

Feature: User Registration
  Slice 1: Email/password signup — form, validation, account creation
  Slice 2: Email verification — send email, verify link, UI state
  Slice 3: Social login (OAuth) — Google button, OAuth flow, account link
2. Horizontal Layering

Break by system layer:

Feature: Order Processing
  Layer 1: Data Model       — entities, migrations
  Layer 2: Data Access      — repository, CRUD, queries
  Layer 3: Business Logic   — service, validation rules
  Layer 4: API Endpoints    — routes, error handling
  Layer 5: Frontend         — form, API client, loading/error states
3. Workflow Decomposition

Break by process steps:

Task: Checkout flow
  Step 1: Cart validation   — stock check, quantities, totals
  Step 2: Payment           — collect details, validate, process
  Step 3: Order creation    — record, payment link, inventory update
  Step 4: Confirmation      — email, success page, invoice
4. Component Decomposition

Break by UI or system component:

Task: Dashboard page
  Component 1: Header       — logo, nav, user menu
  Component 2: Stats cards  — revenue, orders, customers
  Component 3: Chart        — sales trend, data fetch/transform
  Component 4: Orders table — sort, pagination, row actions

For more detailed worked examples of each technique, see EXAMPLES.md.

Task Template

For each decomposed task, define:

markdown
## Task: [Brief Title]

**Description:**
[What needs to be done in 1-2 sentences]

**Files to Create/Modify:**
- [ ] path/to/file1.ts
- [ ] path/to/file2.ts

**Steps:**
1. [First specific step]
2. [Second specific step]
3. [Third specific step]

**Done When:**
- [ ] [Success criterion 1]
- [ ] [Success criterion 2]
- [ ] Tests pass

**Dependencies:**
- Requires: [Other task if any]
- Blocks: [What this enables]

Dependency Management

Task Graph:

[Data Model] ──┬──▶ [Repository]
               │

                         [API Endpoints]
Minimize Dependencies
  • Prefer tasks that can run in parallel
  • Use interfaces to decouple dependencies
  • Start with foundational tasks first
Order by Dependencies
Phase 1 (No dependencies):
- Task A: Data model
- Task B: API type definitions
- Task C: UI component skeletons

Phase 2 (Depends on Phase 1):
- Task D: Repository (needs A)
- Task E: API client (needs B)
- Task F: UI logic (needs C)

Phase 3 (Depends on Phase 2):
- Task G: Service (needs D)
- Task H: Connected UI (needs E, F)

Decomposition Checklist

For each task, verify:

  • Atomic? — Can be done without interruption
  • Clear? — Scope is unambiguous
  • Testable? — Know when it's done
  • Independent? — Minimal dependencies
  • Small? — Less than half a day

Integration with Other Skills

  • Use design-first to understand the full scope before decomposing
  • Use verification-gates to define checkpoints between phases
  • Use testing/red-green-refactor to implement each task
