expand-task

A command that turns one complex task into a set of smaller, ordered subtasks with acceptance criteria.

In plain words
What is it for?
Use it to break down a feature, bug fix, or refactoring task into setup, implementation, testing, integration, and documentation work.
Why use it?
It makes large pieces of work easier to understand and manage. It also highlights dependencies and the steps that may control the schedule.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

expand-task scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Origin

This is a copy

100% identical to expand-task — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

What it actually says

Break down a complex task into subtasks.

Arguments: $ARGUMENTS (task ID)

Intelligent Task Expansion

Analyzes a task and creates detailed subtasks for better manageability.

Execution

task-master expand --id=$ARGUMENTS

Expansion Process

  1. Task Analysis

    • Review task complexity
    • Identify components
    • Detect technical challenges
    • Estimate time requirements
  2. Subtask Generation

    • Create 3-7 subtasks typically
    • Each subtask 1-4 hours
    • Logical implementation order
    • Clear acceptance criteria
  3. Smart Breakdown

    • Setup/configuration tasks
    • Core implementation
    • Testing components
    • Integration steps
    • Documentation updates

Enhanced Features

Based on task type:

  • Feature: Setup → Implement → Test → Integrate
  • Bug Fix: Reproduce → Diagnose → Fix → Verify
  • Refactor: Analyze → Plan → Refactor → Validate

Post-Expansion

After expansion:

  1. Show subtask hierarchy
  2. Update time estimates
  3. Suggest implementation order
  4. Highlight critical path

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
