Fed it a deliberately flawed 4-step caching plan against a small fake repo: the structured multi-perspective pass caught a nonexistent invalidation call, an unbounded in-memory cache, a no-rollback ship step, AND a cross-user cache-key permission leak and multi-worker staleness risk that a naive single-pass review completely missed.

Scored on four weighted criteria — install, triggering, output vs. baseline, docs. How scoring works

  • Installs cleanly 5/5
  • Triggers reliably 5/5
  • Output vs. baseline 8/10
  • Docs & honesty 5/5

What Replan does

Given a plan already in the conversation or a file path, dispatches parallel review subagents (codebase alignment, best practices, feasibility, project standards, security, fresh perspective, etc., chosen adaptively per plan type) and merges their critical/important/minor findings directly back into the plan. Triggers when the user has a draft implementation, research, design, or migration plan and wants it validated before execution, or invokes /replan; a companion skill in the same repo, recheck, does the post-implementation counterpart.

How to install Replan

git clone https://github.com/kojott/claude-replan
cd claude-replan
mkdir -p ~/.claude/skills
cp -r plugin/skills/replan ~/.claude/skills/replan

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Replan

  • /replan Pressure-tests an implementation plan with adaptive multi-perspective subagents before you write code.

It also activates on plain-language prompts like these:

  • I wrote an implementation plan for this migration, review it first.
  • Validate my design plan for the onboarding flow before I build it.
  • Pressure-test this caching plan before I start implementing it.

Frequently asked questions

Is the Replan skill free?
Yes. The skill itself is free from kojott/claude-replan. SkillProof publishes the install command and an independent test verdict at no cost.
Does Replan work with Claude Code?
We tested it with Claude Code 2.x (agent harness) on Jul 15, 2026. Verdict: Tested · Works. Fed it a deliberately flawed 4-step caching plan against a small fake repo: the structured multi-perspective pass caught a nonexistent invalidation call, an unbounded in-memory cache, a no-rollback ship step, AND a cross-user cache-key permission leak and multi-worker staleness risk that a naive single-pass review completely missed.
What is the Replan SkillProof Score?
9.2/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 8/10, docs & honesty 5/5.
How do I install Replan?
Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.
Can I use Replan with Cursor, Copilot, Gemini CLI, Codex or other AI tools?
The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.
