rust-2026-template GEMINI.md

A project-specific instruction file for Gemini, Google’s AI coding assistant, in a Rust 2026 template repository. It points to the shared project rules and lists Gemini-specific practices.

In plain words
What is it for?
Use it to guide Gemini’s web searches, parallel file inspection, and early workspace-wide Rust checks during refactors.
Why use it?
It keeps Gemini’s tool guidance separate from the repository’s common rules while showing how to verify Rust changes.

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

rust-2026-template 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 3d 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.

Tool-Specific Guidance

  • Use google_web_search to stay updated on the latest Rust ecosystem developments and crate documentation.
  • Leverage parallel ReadFile calls when inspecting multiple related files.
  • Always verify large-scale refactors with cargo check --workspace early in the process.
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.
