mcp-logic: Instructions file for Gemini CLI

GEMINI.md

mcp-logic GEMINI.md is an instructions file for Gemini CLI from angrysky56/mcp-logic. It costs 837 tokens per session, scanned A, original, MIT.

A project guide for mcp-logic, an MCP server that gives AI clients eight logical-reasoning tools. It records the project's current work, architecture, tests, and workflow.

In plain words
What is it for?
Use it to plan, execute, track, and verify the project's five hardening phases with the documented GSD commands and architecture notes.
Why use it?
It gives coding agents the project context they need before changing code, including known problems and the current milestone.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md.

This is angrysky56/mcp-logic's own configuration. It tells Gemini CLI how to work on mcp-logic itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything mcp-logic configures →

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

mcp-logic GEMINI.md scanned grade A with 1 finding 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.

Runs shell commandslowCapability

Expected in a hook, worth knowing in a rule or an instructions file.

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.
