harness:subagent-driven-development

What problem does it solve?

This Skill helps you reliably execute an implementation plan by delegating each task to fresh, isolated subagents and enforcing a two-stage review cycle so work stays spec-compliant and code-quality sound.

Core Features & Use Cases

• Fresh subagent per task: Dispatches a dedicated implementer with no inherited session history to reduce context pollution and improve focus.
• Two-stage review checkpoints: Runs spec compliance review first, then code quality review, with iterative fix-and-retry until approvals.
• Continuous execution within a session: Minimizes human check-ins and proceeds task-by-task unless blocked by unresolved ambiguity or an actual BLOCKED status.
• Safety guardrails via harness-delta: Requires reading harness-delta.md first and enforces features.json grounding to prevent orphan subagent work.
• Role-based model sizing: Recommends using the least capable model that fits each role (implementer, reviewers, and higher-judgment tasks).

Quick Start

Use it when you have an implementation plan and want to execute its mostly independent tasks using isolated subagents with spec-first then quality-first reviews.
