In plain words

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 $0.00015 $0.00096

Security

Grade A, and why

superpowers-review 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

Review Skill

When to use this skill

  • before delivering final code changes
  • after implementing a planned set of steps
  • before merging or shipping

Severity levels

  • Blocker: wrong behavior, security issue, data loss risk, broken tests/build
  • Major: likely bug, missing edge cases, poor reliability
  • Minor: style, clarity, small maintainability issues
  • Nit: optional polish

Checklist

  1. Correctness vs requirements
  2. Edge cases & error handling
  3. Tests (adequate coverage, meaningful assertions)
  4. Security (secrets, auth, injection, unsafe defaults)
  5. Performance (obvious hotspots, N+1, unnecessary work)
  6. Readability & maintainability
  7. Docs / comments updated if needed

Output format

  • Blockers
  • Majors
  • Minors
  • Nits
  • Overall summary + next actions

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.
