gemini-superpowers-antigravity: Skill for Claude Code

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

superpowers-workflow is a skill for Claude Code, Codex from anthonylee991/gemini-superpowers-antigravity. It costs 47 tokens per session (474 once invoked), scanned A, original, MIT.

A step-by-step workflow for software changes: explore the problem, make a plan, implement it, verify it, review it, and finish. TDD, or test-driven development, means writing tests before or alongside the code when practical.

In plain words
What is it for?
Use it for non-trivial code changes, bug fixes, refactors, automation workflows, tests, and reliability or safety improvements.
Why use it?
It gives coding, debugging, refactoring, and automation work a consistent sequence with checks before completion.

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.

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-workflow 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 10d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/record_activation.py, scripts/spawn_subagent.py, scripts/write_artifact.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Superpowers Workflow

This skill defines the default operating procedure for software and automation tasks.

When to use this skill

Use whenever the user asks to:

  • build or modify code
  • debug an error or failing tests
  • refactor or improve quality
  • design an automation workflow (e.g., API integrations, ETL, pipelines)
  • add tests, reliability, or safety checks

Activation marker (required)

Immediately after reading this skill (before any other output), run:

python .agent/skills/superpowers-workflow/scripts/record_activation.py --skill superpowers-workflow

Default workflow (mandatory unless explicitly unnecessary)

  1. Brainstorm (short): clarify goal, constraints, risks, and acceptance criteria.
  2. Write a plan: small steps (2–10 minutes each) with files + verification.
  3. Implement: make the smallest correct change; prefer tests-first when feasible.
  4. Review pass: correctness, edge cases, security, style, maintainability.
  5. Finish: run verification commands, summarize changes + next steps.

Decision tree: how much process is needed?

  • Tiny change (1 file, obvious):
    • Do a mini-brainstorm (3 bullets), then mini-plan (3–5 steps), then implement + verify.
  • Non-trivial change:
    • Full brainstorm + plan before editing.
  • High-risk change (auth, money, prod data, security, migrations):
    • Add explicit risk controls: rollback plan, dry-run, extra tests, logging, safe defaults.

Output rules (how you communicate)

  • Always state assumptions if anything is ambiguous.
  • Always include verification (commands, tests, or observable checks).
  • If you must ask questions, ask at most 3; then proceed with best assumptions.

Stop conditions

Pause implementation and switch to planning if:

  • requirements conflict
  • critical unknowns block correctness
  • the change could cause data loss or security issues without safeguards
Files

What ships with it

3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

superpowers-workflow is a skill published in the GitHub repository anthonylee991/gemini-superpowers-antigravity (827 stars, last pushed 7mo ago), licensed MIT. It adds 47 tokens to every session and 474 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 2026-08-30.
