Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is benjisho/windows-mtr's own configuration. It tells Codex and OpenCode 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 AGENTS.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.

AGENTS.md

Codex operating notes for windows-mtr (repository scope).

Mission and guardrails

  • Keep windows-mtr reliable, secure, and predictable for network diagnostics.
  • Prefer small, reviewable pull requests with clear user impact.
  • Preserve CLI compatibility unless a change is explicitly requested and documented.

Required workflow

  1. Read context first: README.md, USAGE.md, and touched source/tests/docs.
  2. Plan a minimal safe diff (avoid unrelated refactors).
  3. Implement with explicit error handling and no silent network fallbacks.
  4. Validate with relevant checks.
  5. Update docs/changelog when behavior, UX, install, API, or release flow changes.

Repository map

  • src/ — application code.
  • tests/ — integration/unit/report tests.
  • examples/ — sample usage.
  • xtask/ — automation helpers.
  • docs/ — project documentation.

Toolchain and validation

  • Rust/toolchain expectations follow repo docs and CI (currently Rust 1.88.0+ / MSRV from Cargo.toml).
  • For Rust changes, run when available:
    • cargo fmt --all -- --check
    • cargo clippy --all-targets --all-features -- -D warnings
    • cargo test --all
  • For workflow/docs hygiene changes, run targeted checks (for example pre-commit run --all-files, actionlint, markdown lint).
  • If a command cannot run, report the exact command and concrete environment blocker.

API/OpenAPI checks (when API contract/spec changes)

  • python3 scripts/validate_openapi_schema.py
  • scripts/check_openapi_compat.sh <base-ref>

Security and sensitive-change caution

  • Treat CLI args, hostnames, packet data, and files as untrusted inputs.
  • Avoid logging sensitive data or adding telemetry/data-exfil behavior.
  • Keep dependencies minimal and justified.
  • Use extra care and minimal diffs for:
    • .github/workflows/**, release/version/tagging/packaging automation.
    • Security policy/audit/dependency configuration.

Documentation expectations

Update docs when changing:

  • CLI flags/options/defaults.
  • Output/report/API schema.
  • Build/install/run/release behavior.

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.
