superpowers

superpowers is a skill for Claude Code, Codex from Peiiii/nextclaw. It costs 43 tokens per session (1,671 once invoked), scanned A, original, MIT.

A structured software-development workflow covering design before coding, written implementation plans, test-driven development, debugging, code review, and verification. Test-driven development, or TDD, means writing tests before the code they check.

In plain words
What is it for?
Use it to plan multi-step changes, follow TDD, investigate bugs systematically, review code, and verify that a task is actually complete.
Why use it?
It helps turn broad coding tasks into planned, testable work and encourages finding the underlying cause of bugs before changing code.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

superpowers scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Superpowers

Overview

Use this skill when the user wants a stronger engineering workflow inside NextClaw.

This marketplace skill adapts the upstream obra/superpowers project into a single installable NextClaw skill. Because NextClaw marketplace installs one skill directory at a time, this package provides:

  • one top-level workflow router,
  • bundled local reference files for the most useful upstream superpowers skills,
  • and clear rules for when to load which reference.

Be explicit about the boundary:

  • This skill owns workflow selection, expectation-setting, and reference routing.
  • The bundled reference files own the detailed superpowers methodology.
  • NextClaw, the current project rules, and the actual tool runtime own execution.

Do not present bundled superpowers guidance as a higher-priority authority than the user's instructions, the current project's AGENTS.md, or the host platform's rules.

What This Skill Covers

  • design-first brainstorming before implementation,
  • implementation plan writing for multi-step work,
  • test-driven development for feature and bugfix work,
  • root-cause-first debugging,
  • pre-merge or post-task code review prompts,
  • evidence-before-claims verification,
  • optional subagent-driven execution when the environment actually supports it.

What This Skill Does Not Cover

  • overriding user instructions or project rulebooks,
  • pretending NextClaw natively supports the upstream superpowers multi-directory auto-discovery model,
  • forcing subagent workflows when the current runtime does not support them,
  • claiming a workflow step happened when the needed evidence was not actually collected,
  • replacing domain-specific project skills that are more specific than this general workflow skill.

Install Boundary

Always distinguish these paths:

  • NextClaw marketplace install: nextclaw skills install superpowers
  • Installed NextClaw skill assets: <workspace>/skills/superpowers/
  • Upstream standalone installation outside NextClaw: clone https://github.com/obra/superpowers and follow the upstream install docs

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

superpowers is a skill published in the GitHub repository Peiiii/nextclaw (256 stars, last pushed today), licensed MIT. It adds 43 tokens to every session and 1,671 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
