Plan Review

Purpose

This skill validates an implementation plan before implementation begins.

The review confirms that the plan is complete, consistent, traceable, and ready for execution.

Plan Review is the final quality gate before implementation authorization.

When to Use

Use this skill when:

• a new implementation plan has been created;
• an implementation plan has been significantly revised;
• implementation authorization is required.

Always perform this review before implementation begins.

---

Inputs

Required:

• implementation plan;
• PROJECT.md;
• ROADMAP.md;
• ARCHITECTURE.md;
• ENGINEERING.md.

Additional references:

• ADRs;
• completed plans;
• current repository state (when relevant).

The implementation plan is the proposed engineering contract.

---

Outputs

Produce one review outcome:

• Approved
• Approved with Minor Suggestions
• Changes Requested

When revisions are required, provide clear, prioritized, and actionable feedback.

---

Procedure

Step 1 — Build Context

Review:

• project definition;
• roadmap;
• architecture;
• engineering design;
• ADRs;
• completed plans.

Understand why this implementation increment exists.

---

Step 2 — Verify Scope

Confirm that:

• scope is explicit;
• implementation boundaries are clear;
• work fits the current roadmap phase;
• engineering conventions are respected;
• undocumented work has not been introduced.

Every major implementation item should be traceable to approved project documentation.

---

Step 3 — Verify Completeness

Confirm the plan contains:

• objective;
• scope;
• out-of-scope items;
• acceptance criteria;
• validation strategy;
• implementation checklist;
• identified risks.

Implementation should not require inventing missing requirements.
