Agent skills to upgrade plan mode and debugging, enforce best practices, and enhance native features, not replace them.
Use only when a slow-powers developer explicitly asks for a post-session audit of how slow-powers skills were used during the session just completed. A manual diagnostic for people working ON slow-powers — never relevant to ordinary development tasks; do not auto-invoke.
Use when testing whether a new skill improves agent behavior, or when validating a change to an existing skill's language.
Use right after you've drafted or revised an implementation plan and before you present it or start coding — a fresh-eyes review that catches placeholders, hallucinated file references, irrelevant steps, and coverage gaps before the user has to
Use when encountering any bug, test failure, build error, or unexpected behavior.
Use when implementing any feature, refactoring, or writing a bugfix.

Slow-powers is an agent skill set for professional software development. It enhances plan mode and debugging work, enforces best practices, and works with the features of modern agents, instead of replacing them. It's the plugin for people who don't install plugins.
The test-driven-development skill catching a race before it ships. Terminal themed with Synthpunk Neon Dark.
Slow-powers is a fork of obra/superpowers. Much of the skill content is sourced from upstream, with rewrites focusing on clarity, token efficiency, and providing a generally lighter touch.

Slow-powers is designed to improve the actual day-to-day work of software developers using agents for anything from focused debugging to generating entire features. It instructs agents to check for skills first, and use the ones that apply. The shipped skills fill real gaps in agentic development, but all discoverable skills benefit from the skill-enforcing guidance. Combined with the provided skill-writing and testing guidance, this allows you to extend your workflow with your own verified-to-be-useful skills.
Even small features are developed better with a plan. Slow-powers hardens the plan to catch hallucinations and other mistakes before you review it. During implementation, skills guide the agent through best practices, working in isolation, following test-driven development, and reviewing and verifying its work before it hands it back to you.
Slow-powers guides agents through an evidence-backed, no-guess debugging approach. No "It works now!" without proof. There's also special guidance for specific, tricky-to-debug situations, generated from real-world cases.
Skills for writing skills! Slow-powers skills are all written and evaluated following the same guidelines and processes it ships. Back up your own skills with real stats, and understand their cost in time and tokens, so you can develop custom workflows when needed.
Skill evaluations are powered by eval-magic
