In plain words
What is it for?

Why use it?
They keep code changes compatible with the existing command-line behavior and require checks that catch formatting, lint, and test failures.

Instructions file for GitHub Copilot

Written for GitHub Copilot: a Copilot instructions file.

This is benjisho/windows-mtr's own configuration. It tells GitHub Copilot how to work on windows-mtr 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 windows-mtr 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

windows-mtr rust.instructions.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.

What it actually says

Rust code generation instructions for windows-mtr

  • Preserve CLI compatibility unless explicitly requested.
  • Follow existing error handling patterns and avoid silent fallbacks.
  • Add or adjust tests for behavior changes.
  • Prefer minimal diffs; avoid broad refactors unrelated to the task.
  • Validate with:
    • cargo fmt --all -- --check
    • cargo clippy --all-targets --all-features -- -D warnings
    • cargo test --all
  • If checks cannot run, state the exact environment blocker and stop short of fabrication.
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.
