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 | $0.00285 | $0.00285 |
| Opus 5 | $0.00143 | $0.00143 |
| Sonnet 5 | $0.00057 | $0.00057 |
| Haiku 4.5 | $0.00028 | $0.00028 |
Grade A, and why
logic-lens GEMINI.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 7d 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
Logic-Lens — Developer Guide (Gemini CLI)
This file contains instructions for Gemini CLI agents working on the Logic-Lens repository.
Invoking Skills
In Gemini CLI, invoke skills with the / prefix:
/logic-review — logic bug review
/logic-explain — execution path explanation
/logic-diff — semantic equivalence check
/logic-locate — fault localization
/logic-health — aggregate logic health dashboard
/logic-fix-all — autonomous audit-and-fix pipeline
Installation
Install via Gemini CLI extension system using gemini-extension.json at the repository root.
Project Layout
See CLAUDE.md for the full layout. The core content lives in skills/ as platform-agnostic Markdown. Gemini-specific metadata is in gemini-extension.json.
Key Conventions
skills/_shared/is the shared framework. All skills load it on demand.- Every finding must follow Premises → Trace → Divergence → Trigger → Remedy (Iron Law).
- Risk codes L1–L9 are defined in
skills/_shared/logic-risks.md. - Version in
package.jsonis the source of truth.
No Hooks
The session-start hook is Claude Code only. Gemini CLI discovers skills via gemini-extension.json and does not use hooks.
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.

logic-lens GEMINI.md is an instructions file published in the GitHub repository hyhmrright/logic-lens (22 stars, last pushed 8d ago), licensed MIT. It adds 285 tokens to every session, about $0.0014 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.
