gemini-superpowers-antigravity: Skill for Claude Code

.agent/skills/superpowers-brainstorm/SKILL.md

superpowers-brainstorm is a skill for Claude Code, Codex from anthonylee991/gemini-superpowers-antigravity. It costs 35 tokens per session (206 once invoked), scanned A, original, MIT.

A structured planning guide for brainstorming before a substantial coding or design change.

In plain words
What is it for?
Use it for non-trivial features, unclear refactors, complex debugging, and automation designs.
Why use it?
It helps clarify the goal, constraints, risks, possible approaches, and signs that the work is complete before implementation begins.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one.

This is anthonylee991/gemini-superpowers-antigravity's own configuration. It tells Claude Code and Codex how to work on gemini-superpowers-antigravity itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything gemini-superpowers-antigravity configures →

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.

Opus 5.5 $0.00014 $0.00082

Security

Grade A, and why

superpowers-brainstorm 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 2mo 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.

What it actually says

Brainstorm Skill

When to use this skill

  • before implementing non-trivial features
  • before refactors with unclear scope
  • before debugging complex issues
  • before designing an automation workflow

Brainstorm template (use this exact structure)

Goal

  • (1–2 sentences)

Constraints

  • (tech stack, time, compatibility, performance, “must not change”, etc.)

Known context

  • (what exists today; relevant files/components; current behavior)

Risks

  • (security, data loss, regressions, surprising side effects)

Options (2–4)

For each option include:

  • Summary
  • Pros / cons
  • Complexity / risk

Recommendation

  • Pick one option and explain why

Acceptance criteria

  • Bullet list of verifiable outcomes

What this file has done since we first saw it

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.
