copilot-governance: Instructions file for Gemini CLI

GEMINI.md

copilot-governance GEMINI.md is an instructions file for Gemini CLI from chf3198/copilot-governance. It costs 213 tokens per session, scanned A, a copy of copilot-governance CLAUDE.md, MIT.

A template that tells Gemini CLI, a command-line coding assistant, which project rules and guidance files to load. An installer fills in the local repository path and writes the resulting file to Gemini’s configuration folder.

In plain words
What is it for?
Installing and maintaining governance rules for coding-agent behavior, GitHub work, repository onboarding, releases, workflows, and Playwright usage.
Why use it?
It keeps shared instructions in the repository while generating a machine-specific Gemini configuration. This avoids manually copying rules or hard-coding paths.

Instructions file for Gemini CLI

Written for Gemini CLI: the file is GEMINI.md. Also seen: mentions Gemini CLI.

This is chf3198/copilot-governance's own configuration. It tells Gemini CLI how to work on copilot-governance 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 copilot-governance 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

copilot-governance 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 2mo 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

88% identical to copilot-governance CLAUDE.md — 6 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.
