402-mcp: Instructions file for Gemini CLI

GEMINI.md

402-mcp GEMINI.md is an instructions file for Gemini CLI from forgesworn/402-mcp. It costs 5 tokens per session, scanned A, a copy of 402-mcp copilot-instructions.md, MIT.

Instructions for the Gemini command-line tool when it works on the 402-mcp project, a server for agents that use payment-protected APIs. They explain how the project is built, tested, structured, and secured.

In plain words
What is it for?
They guide Gemini through build, test, and type-check commands, testable tool design, spending limits, payment-data validation, safe outgoing requests, and commit-message conventions.
Why use it?
They help Gemini follow the repository’s existing practices instead of making assumptions about its TypeScript code and payment handling.

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

402-mcp 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.

Origin

This is a copy

95% identical to 402-mcp copilot-instructions.md — 4 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

Changes

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.
