codex-switch: Instructions file for Codex

AGENTS.md

codex-switch AGENTS.md is an instructions file for Codex, OpenCode from ChArLiEdance/codex-switch. It costs 227 tokens per session, scanned A, original, MIT.

A set of repository instructions for codex-switch that keeps Windows and macOS implementation work separate where possible.

In plain words
What is it for?
It is for deciding where Windows and macOS code belongs and choosing the matching build, check, test, and compilation commands.
Why use it?
It prevents platform-specific changes from being mixed unnecessarily and avoids running checks for an unrelated operating system.

Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is ChArLiEdance/codex-switch's own configuration. It tells Codex and OpenCode how to work on codex-switch 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 codex-switch 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

codex-switch 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.

What it actually says

Repository AGENTS

Platform Isolation

  • Windows and macOS should be developed independently whenever practical.
  • Do not introduce shared modules or shared runtime paths unless the behavior is a necessary cross-platform contract, disk format, or build/versioning concern.
  • Do not extract or expand shared modules for platform-specific behavior unless the shared code is strictly necessary for identical cross-platform contracts, on-disk formats, or version/build plumbing.
  • When syncing a feature from one platform to the other, prefer implementing or adapting it under src-tauri/win/** or src-tauri/mac/** first. Use src-tauri/shared/** only for unavoidable neutral contracts.
  • For Windows-only changes, use Windows-only compile, check, test, and build commands; do not run validation paths that require compiling src-tauri/mac/** unless the task explicitly touches macOS.
  • Windows Vite/Tauri build commands should be run with escalation by default. In this repository, sandboxed builds are known to fail with spawn EPERM while starting esbuild from the Vite/Tauri beforeBuildCommand.
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.
