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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00027 | $0.00305 |
| Opus 5.5 | $0.00011 | $0.00122 |
| Sonnet 5.5 | $0.00005 | $0.00061 |
| Haiku 4.5 | $0.00003 | $0.00030 |
Grade A, and why
contributing-to-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 yesterday.
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
Contributing to superpowers-antigravity
This repository is a native Antigravity port of upstream superpowers. Three rules govern every edit under skills/, agents/, rules/ and .github/.
The purity law. Skill, agent and rule text names only Antigravity's own tools and features: no other agent product, no other product's tool names, no tool-mapping file. .github/ names no other agent product either. The banned vocabulary is tests/antigravity/purity-patterns.txt; the tool names skill text may use are the baseline class in tests/antigravity/known-tools.txt.
R3: verbatim port or recorded divergence. Text ported from upstream stays word for word. Any change to it is a divergence, recorded in the spec and the release notes of the change that makes it.
R6: shell neutrality. Skill text works under any shell Antigravity's command tool runs: prefer native tools, give commands that behave the same in every shell, and invoke a bundled script through its interpreter, never by its bare path.
Before you report an edit done, run bash tests/run-tests.sh from the repository root (Git Bash on Windows) and fix every FAIL. A SKIP is not a pass.
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.

contributing-to-superpowers is a skill published in the GitHub repository roundpilot/superpowers-antigravity (80 stars, last pushed yesterday), licensed MIT. It adds 27 tokens to every session and 305 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-11-06.
