# Gaf Complexity Decomposer

> Classifies GAF tasks into SIMPLE, MID_COMPLEX, or COMPLEX and proposes modular decomposition and execution order. Use when planning new tasks, scoping large improvements, or splitting complex automations.

# GAF Complexity Decomposer

## Goal
Apply GAF complexity-tier rules and produce a concrete module plan for implementation.

## Use This Skill When
- New automation requirements are unclear in size/scope.
- User asks how to break down a complex task.
- Existing task needs a major "Improve" refactor.

## Inputs
- problem statement
- expected outputs
- data sources and dependencies
- operational constraints (SLA, reliability, ownership)

## Procedure
1. Classify as `SIMPLE`, `MID_COMPLEX`, or `COMPLEX` using `gaf-core-knowledge/docs/task-complexity-tiers.md`.
2. For non-simple work, propose module boundaries with clear responsibilities.
3. Define interface contract between modules (inputs/outputs, dependencies).
4. Sequence modules into incremental delivery steps.
5. Identify validation checkpoints for each module.

## Output
- chosen complexity tier and rationale
- module breakdown (or single-task plan for SIMPLE)
- phased implementation order
- validation gate per phase/module

## Guardrails
- Do not keep a COMPLEX task as a single opaque implementation.
- Prefer decomposition that minimizes cross-module coupling.
