SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Executing a large approved implementation plan requires coordinating parallel work lanes, tracking execution state, handling amendments, and verifying completeness without drifting from the approved contract. This Skill acts as the orchestrator and integrator for approved Happier repository plans, keeping the plan authoritative while every unit is implemented, reviewed, and verified.

Core Features & Use Cases

  • Plan-authoritative execution: Recovers the approved contract, requirement IDs, execution units, and acceptance criteria, then drives each unit through the shared happier-implement workflow without redesigning the plan.
  • Parallel lane orchestration: Builds the critical path and ready queue, dispatches plan-aware implementation, QA, and review lanes, and integrates their diffs and evidence at substantial boundaries.
  • Amendment and completion governance: Routes contract changes through user-approved amendments and closes plans only when every material requirement maps to verified evidence.
  • Use Case: After approving a multi-part refactor plan in the Happier repository, you ask the agent to execute it; the Skill resumes prior state, dispatches independent lanes in parallel, triages review findings, and reports verified completion with residual risks.

Quick Start

Use happier-implement-plan to execute the approved implementation plan at the path I specify and report verified completion status.

FAQPage Schema
How do I execute an approved implementation plan with an AI agent?

Name the approved plan and explicitly ask to implement, resume, or complete it. The Skill reads the plan from disk, recovers execution state, dispatches parallel lanes for each unit, and reports verified completion with evidence.

How does plan execution handle parallel work lanes?

It builds a critical path and ready queue from the plan's execution units, then dispatches independent implementation, QA, and review lanes in parallel. Lanes integrate at substantial boundaries, and file overlap alone is not treated as a collision.

Can the agent change the plan during implementation?

No. The approved plan remains authoritative. When evidence shows a requirement is unsafe, contradictory, or stale, the affected unit pauses, an amendment is proposed, and execution resumes only after explicit user approval.

What happens when a review finds defects during plan execution?

Findings are treated as candidate claims that must be reproduced and adjudicated through the happier-review workflow. Confirmed defects are clustered by root cause and fixed through the standard implementation workflow, then re-reviewed.

When is a plan considered complete?

Only when every material requirement maps to VERIFIED_COMPLETE, an approved supersession, or a defensible NOT_APPLICABLE, with RED/GREEN proof, broader validation, and live QA. Compilation, checkboxes, or partial tests do not count as completion.
