Overview

What you provide

A feature request, repository context and the host assistant configuration.

What you get

A design, task plan, implementation and verification artifacts produced through the host agent.

Choosing this tool

Choose Superpowers when an agent regularly starts coding before requirements are settled. Its staged workflow is useful for a feature with several dependent changes. Ponytail is a narrower fit for limiting unnecessary implementation; Addy Osmani Agent Skills offers explicit lifecycle commands and engineering checklists.

A decision worked through

For a new account settings screen, agree on fields and failure states before approving the plan. Then inspect the implementation and test results. A smaller diff is not proof of correctness, and extra planning or review calls still consume the host model budget.

Superpowers: alternatives and trade-offs

Compare Superpowers on the documented workflow and cost boundary below; this is an official-source comparison, not a hands-on benchmark.

Product	Price / unit	Free allowance	Input → output	Key limit
SuperpowersRead profile Official source ↗	MIT; host usage extra	Full source	Request → staged implementation	Requires a compatible agent
PonytailRead profile Official source ↗	MIT; agent billed separately	Repository skill	Code change → smaller reviewed solution	Host adapters have different commands
Addy Osmani Agent SkillsRead profile Official source ↗	MIT; infrastructure extra	Full skill collection	Spec or diff → engineering checks	Single-skill installs can omit references

Setup & workflow

Read the installation instructions for your assistant.
Install the plugin and start a fresh session.
Try one bounded feature and inspect its plan, diff and checks.

Requirements & installation

Use a supported coding assistant and install the pack separately for each harness.

Limits & review

Workflow instructions depend on the host following them. Automatic activation can add process to small tasks; upstream performance claims have not been independently tested here.

Your part

Approve the design and review the final diff and actual test evidence before merging.
