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 | $0.00216 | $0.00216 |
| Opus 5 | $0.00108 | $0.00108 |
| Sonnet 5 | $0.00043 | $0.00043 |
| Haiku 4.5 | $0.00022 | $0.00022 |
Grade A, and why
codex-antigravity-collaboration AGENTS.md 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
Repository guidance
This repository is the canonical shared source for cross-runtime rules and global core Skills.
- Start with
CANONICAL_MANIFEST.jsonto resolve ownership and restore targets. - Shared rules live in
shared/rules/; global Skills live inshared/skills/GLOBAL_CORE/. - Treat backups, generated copies, runtime caches, and open migration branches as evidence, not as canonical sources.
- Keep root
SKILL.mdfiles focused on routing, essential workflow, and safety boundaries. Read linked references only when the current task needs them. - Use a clear specialized Skill directly; resolve routing only when multiple material paths remain.
- Preserve model-agnostic shared behavior. Put model- or platform-specific behavior in the owning thin-adapter repository.
- Make the smallest relevant change and use proportional validation. For Skill or manifest changes, run
pwsh -File scripts/validate-canonical-skills.ps1andgit diff --check. - Do not weaken approval or secret-handling boundaries, merge default branches, or overwrite unrelated work.
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.

codex-antigravity-collaboration AGENTS.md is an instructions file published in the GitHub repository a275618631/codex-antigravity-collaboration (10 stars, last pushed yesterday), licensed MIT. It adds 216 tokens to every session, about $0.0011 per session on Opus 5. A static security scan graded it A with 0 findings.
