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 | $0.00444 | $0.00444 |
| Opus 5 | $0.00222 | $0.00222 |
| Sonnet 5 | $0.00089 | $0.00089 |
| Haiku 4.5 | $0.00044 | $0.00044 |
Grade C, and why
The-Pre-Flight-Check GEMINI.md scanned grade C with 2 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 9d 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.

Pre-Flight Check — Gemini CLI Context
This file is loaded as persistent context by Gemini CLI on every prompt. It instructs Gemini to run a fail-fast quality gate pipeline before declaring any task complete or committing code.
The engine (
run-pipeline.py) is vanilla Python 3 with zero external deps.
@./skills/pre-flight-check/SKILL.md
Gemini-specific notes
Running the pipeline
python3 .pre-flight-check/scripts/run-pipeline.py
If that path doesn't exist, the skill is not installed for this project. Install it:
curl -fsSL https://raw.githubusercontent.com/mirekondro/The-Pre-Flight-Check/main/install.sh | bash -s -- --project
Available as an Agent Skill
pre-flight-check is also discoverable as an Agent Skill under .agents/skills/pre-flight-check/ (or .gemini/skills/pre-flight-check/). When active as a Skill, Gemini will self-invoke the pipeline at the checkpoints defined in SKILL.md without you needing to ask explicitly.
To install the Skill tier for Gemini:
bash install.sh --project # installs to .agents/skills/ in addition to the script
Output blocks

### ✅ PRE-FLIGHT PASSED |

Proceed. |
### ❌ PRE-FLIGHT FAILURE: [STAGE] |

Stop. Read the Context for AI Fix block. Fix the named file at the named line. Re-run. |
### ⚠️ PRE-FLIGHT SKIPPED: … |

Runtime undetected. Verify you're running from the project root and the manifest file exists (package.json / pyproject.toml / requirements.txt). |
Reload context
If you've just installed the skill or updated SKILL.md and Gemini doesn't seem aware of the protocol, run /memory reload to re-scan all context files.
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.

The-Pre-Flight-Check GEMINI.md is an instructions file published in the GitHub repository mirekondro/The-Pre-Flight-Check (2 stars, last pushed 2mo ago), licensed MIT. It adds 444 tokens to every session, about $0.0022 per session on Opus 5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
