task-decomposition

task-decomposition is a skill for Claude Code, Codex from a5c-ai/babysitter. It costs 0 tokens per session (341 once invoked), scanned A, original, MIT.

A planning workflow that breaks a large software epic into smaller tasks that can be assigned and worked on separately. It adds acceptance criteria, effort sizes, and a dependency graph showing what must happen first.

In plain words
What is it for?
Use it to create task files, define parallel work streams and execution waves, estimate tasks from S to XL, and check that the tasks cover the product requirements.
Why use it?
It turns a broad feature plan into an ordered, checkable work list. This makes parallel work easier to organise and helps reveal missing tasks or requirements.

About the project

Babysitter is a workflow engine for AI coding agents that enforces predefined steps, quality checks, human approvals, and decision records. It is used to coordinate complex, repeatable agent workflows across supported coding tools. The catalogue contains skills, agents, instructions, settings, a plugin, and an MCP integration for its workflow.

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

task-decomposition 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 5d 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.

What it actually says

Task Decomposition

Break epics into parallelizable tasks with acceptance criteria, effort estimates, and dependency graphs.

Agent

Task Analyst - task-analyst

Workflow

  1. Analyze epic and identify 4-5 parallel work streams
  2. Decompose each stream into concrete tasks (parallel)
  3. Set acceptance criteria in Given/When/Then format
  4. Estimate effort (S/M/L/XL) and set parallelization flags
  5. Build cross-stream dependency graph
  6. Validate coverage against PRD user stories
  7. Fill gaps with additional tasks if needed
  8. Write task files to .claude/epics//.md

Inputs

  • projectName - Project name
  • featureName - Feature identifier
  • epic - Epic from Phase 2
  • prd - PRD from Phase 1
  • parallelAgents - Max parallel agents (default: 5)

Outputs

  • Task list with acceptance criteria and effort estimates
  • Work stream definitions
  • Dependency graph with execution waves
  • Coverage report with PRD traceability

Process Files

  • ccpm-task-decomposition.js - Standalone decomposition
  • ccpm-orchestrator.js - Phase 3 of full lifecycle
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

task-decomposition is a skill published in the GitHub repository a5c-ai/babysitter (1,769 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 341 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
