README

claude-replan

A Claude Code plugin for plan validation and post-implementation review. `/replan` validates plans before execution, `/recheck` verifies the implementation matches the plan afterward. Both use parallel review subagents checking from multiple angles.

The problem

You write a plan. It looks solid. You start executing. Three tasks in, you realize the plan assumed a function that doesn't exist, missed a critical edge case, or ignored your project's conventions entirely. Now you're rewriting the plan mid-flight.

The solution

`/replan` throws your plan at a squad of parallel review agents before you write a single line of code. Each agent has a different job — one checks if the code references are real, another stress-tests feasibility, another reads the plan cold and asks "what did everyone miss?"

The result: a plan that's been pressure-tested from every angle, with all findings incorporated automatically.

How it works

You: /replan

Claude: Reviewing the plan with parallel subagents...

  Agent 1 (Codebase alignment)   → Checks referenced files/APIs actually exist
  Agent 2 (Best practices)       → SOLID, DRY, security, error handling
  Agent 3 (Feasibility & risks)  → Missing steps, ordering issues, blockers
  Agent 4 (Fresh perspective)    → Reads the plan cold, finds blind spots
  Agent 5 (Project standards)    → CLAUDE.md conventions, naming, test patterns

  ✓ All agents returned.

  Critical: Plan references `getUserById()` which was renamed to `findUser()` in v3.2
  Critical: Task 4 depends on Task 6 output — wrong ordering
  Important: No error handling for API timeout in Task 2
  Important: Missing rollback strategy for database migration

  → Plan updated with all findings.

Key features

**Adaptive agent selection** — agents are chosen based on what the plan actually covers, not a fixed checklist. A database migration plan gets different reviewers than a UI redesign plan.

**Always includes a "fresh perspective" agent
