Multi-agent engineering pipeline for end-to-end feature development.

Pipeline

REFINE → PLAN → BUILD → TEST → REVIEW

Each stage is a dedicated agent. A single orchestrator command chains them sequentially with human approval gates between each stage.

Usage

Run the full pipeline:

/swe:pipeline <feature description>

Stages

| Stage | Agent | Purpose | |-------|-------|---------| | REFINE | refiner | Clarify the idea, resolve ambiguities, produce feature definition | | PLAN | planner | Break into atomic tasks, produce reviewable markdown plan | | BUILD | builder | TDD implementation — one task at a time (red-green-refactor) | | TEST | tester | Evolving test plan with iterative execution and status tracking | | REVIEW | reviewer | Code review + silent failure hunting + code health analysis |

Design Principles

• Language-agnostic: Adapts to whatever language, framework, and build tool the project uses
• Context-aware: Reads CLAUDE.md and .claude/ config to discover project conventions
• Human gates: Every stage requires explicit approval before proceeding
• Test-driven: BUILD stage follows red-green-refactor cycle
• Living documents: PLAN produces a task plan doc, TEST produces an evolving test plan doc
• Read-only review: REVIEW agent never modifies code — produces findings only

Agents

Each agent can also be invoked independently outside the full pipeline.

refiner (opus, blue)

Explores the codebase, asks clarifying questions, produces a structured feature definition.

planner (opus, green)

Decomposes into atomic tasks with dependencies, writes a markdown plan document for review.

builder (opus, yellow)

Implements tasks one at a time using TDD. Reads project conventions and adapts to any build tool.

tester (sonnet, cyan)

Creates and maintains a living test plan document. Runs iterative test rounds and tracks pass/fail status.

reviewer (opus, red)

Combines three review dimensions: code review (confidence-scored), silent failure hunting, and code health analysis. Never modifies code.
