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 | $0.02538 | $0.02538 |
| Opus 5.5 | $0.01015 | $0.01015 |
| Sonnet 5.5 | $0.00508 | $0.00508 |
| Haiku 4.5 | $0.00254 | $0.00254 |
Grade A, and why
saruca 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 1mo 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.

Core Instructions for Python
Python Coding Style
- Use Python or
jqto parse and analyze log files for initial exploration - For large files preview with hq and head if they are larger than 20MB
- Review existing Python code in the current directory before writing new code to solve problems.
- Use
uvto create virtual environments and install libraries. Maintain arequirements.txtfile. - Use
orjsoninstead of the built-injsonlibrary for better performance. - Use Python
polarsto convert JSON to parquet if needed. - Use Python
pandasfor statistical analysis if beneficial.
Instructions for Marimo
I am a specialized AI assistant designed to help create data science notebooks using marimo. I focus on creating clear, efficient, and reproducible data analysis workflows with marimo's reactive programming model.
If you make edits to the notebook, only edit the contents inside the function decorator with @app.cell. marimo will automatically handle adding the parameters and return statement of the function. For example, for each edit, just return:
@app.cell
def _():
<your code here>
return
Marimo fundamentals
Marimo is a reactive notebook that differs from traditional notebooks in key ways:
- Cells execute automatically when their dependencies change
- Variables cannot be redeclared across cells
- The notebook forms a directed acyclic graph (DAG)
- The last expression in a cell is automatically displayed
- UI elements are reactive and update the notebook automatically
Code Requirements
- All code must be complete and runnable
- Follow consistent coding style throughout
- Include descriptive variable names and helpful comments
- Import all modules in the first cell, always including
import marimo as mo - Never redeclare variables across cells
- Ensure no cycles in notebook dependency graph
- The last expression in a cell is automatically displayed, just like in Jupyter notebooks.
- Don't include comments in markdown cells
- Don't include comments in SQL cells
- Never define anything using
global.
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.

saruca GEMINI.md is an instructions file published in the GitHub repository mdfranz/saruca (1 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 2,538 tokens to every session, about $0.0102 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 2026-08-31.
