Give Claude Code a whole league of superpowers.

SuperDuperPowers is a Claude Code plugin that turns a rough request into a reviewed spec, a bounded plan, cross-checked code and a verified branch, with every model it uses on the record.

Meanwhile, in your terminal…

›Using SuperDuperPowers, let's add rate limiting to the API

◆brainstorming: spec drafted

◆review panel (Claude + Codex): 3 findings, all fixed

✓you approved the spec

◆plan: 3 slices, 9 tasks, contracts first

⇉lanes 1–3 building in parallel

✗Codex review, task 4: the retry window never resets

◆fixed on the same thread, re-verified

✓42 tests pass (fresh run)

✓ledger: 27 seats recorded, 0 off route

Example session

Our story begins with a big coding job…

Every hero has a weakness

Hand an AI coder a large task and the same three villains show up.

The Context Flood

Exploring a big codebase pours everything into one thread, until the thread loses track of the plan.

The Faceless Model

Something wrote this code, but nobody can say which model it was or what effort setting it ran at.

The Echo

A reviewer from the same model family shares the author's blind spots and waves the bug through.

Luckily, help is on the way…

Eight powers, one plugin

Every power is a real part of the plugin. Its secret identity is printed on the card, and the file it lives in is at the bottom.

Precognition

Secret identity: spec review panel

Spots the problems before there's any code. Claude and Codex reviewers pick the spec apart, and nothing gets built until you approve it.

skills/brainstorming

Swarm Recon

Secret identity: scouting pyramid

A swarm of small scouts reads your codebase in parallel. Your main thread gets back a short answer with citations and keeps its context clear.

agents/code-explore.md

Multiplicity

Secret identity: parallel lanes

Splits the plan into slices and builds them side by side as headless Claude Code lanes, one wave at a time.

scripts/lane-run.py

Second Sight

Secret identity: cross-family review

Risky work gets reviewed by the other model family. Claude's code goes to Codex and Codex's goes to Claude, so the reviewer doesn't share the author's blind spots.

skills/code-review

Total Recall

Secret identity: routing ledger

Remembers which model ran every step and at what effort. Any work that went off route shows up in the audit.

scripts/routing-ledger.py

Perfect Casting

Secret identity: model catalog

Every role, from builder to judge, is pinned to a named model and effort in one catalog, so nothing runs on a silent default.

scripts/model-catalog.json

Force Field

Secret identity: enforcement hooks

Eleven hooks watch every dispatch, block the ones that break the routing rules, and tell you plainly what they can't enforce.

hooks/hooks.json

Truth Sense

Secret identity: verification before completion

It won't call anything done without proof. Tests run fresh before any claim that they pass, and again before you merge.

skills/verification-before-completion

How it works

From rough idea to verified branch, in four panels

  1. 1 · Spec

    YouLet's add rate limiting to the API.

    Brainstorming turns your request into a design. Claude and Codex reviewers pick it apart, and nothing gets built until you approve it.

  2. 2 · Plan

    ClaudeThree slices, nine tasks. Contracts go first.

    The work is cut into slices, each with its own files, its own checks and clear contracts with the slices around it.

  3. 3 · Build

    CodexTask 4 never resets its retry window.

    Lanes build in parallel. Every task checks its own work, and risky tasks get a review from the other model family.

  4. 4 · Finish

    ClaudeAll 42 tests pass. Merge, open a PR, keep or discard?

    A fresh test run and a ledger audit come first. Then you make the call.

No hero works alone

Assemble the league

SuperDuperPowers gives each model the job it does best and has them check each other's work.

Claude

The lead

Runs the show from your main thread. It plans the work, makes the calls and keeps you posted.

Codex

The partner

Builds or reviews, whichever Claude isn't doing. It's the other half of every cross-family check.

Grok & Muse

The sidekicks

Add a second opinion to every review. They can flag anything, but they never block a merge.

The Judge

The tiebreaker

Steps in only when reviewers disagree, and lays out its reasoning so Claude can rule.

You

The hero

You approve the spec, choose who builds and decide whether to merge. Nothing you can't undo happens without your say.

Later, in the changelog…

Powers you can measure

The plugin measures its own routing choices and writes the results up in its changelog. A few of them:

11.91.9min

Median time per judgment scout on Sonnet 5.5 at high effort, against Haiku 5.5 at max, across 129 measured seats.

88vs81

Items found on the same brief by the faster seat, in 7.8 minutes instead of 20.1. It cost $2.17 against $1.19, and the ledger shows both.

8.3min

A scripted two-file Codex build, end to end. Its first self-review caught a real shell-ordering bug.

23releases

Shipped so far, from 0.1.0 to 0.9.7, each one written up in the changelog.

Figures come from the project's changelog and method notes, measured by its author.
