wgm: Instructions file for Codex

AGENTS.md

wgm AGENTS.md is an instructions file for Codex, OpenCode from agent-frontier/wgm. It costs 314 tokens per session, scanned A, original, MIT.

Repository instructions for wgm, a portable agent skill with validation scripts rather than a server to run. They describe its build, validation, operational notes, and code patterns.

In plain words
What is it for?
Running the project's validation harness, checking shell behavior, and working safely with Podman, Docker, temporary home directories, and platform-boundary tests.
Why use it?
They tell a coding agent how to verify changes and avoid treating simulated test results or real user files as reliable test evidence.

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

This is agent-frontier/wgm's own configuration. It tells Codex and OpenCode how to work on wgm 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 wgm 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

wgm 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

AGENTS.md

Build & run

This repository is a portable Agent Skill; it has no application server to start. Work from the repository root.

make validate

Validate (backpressure)

make validate

For focused work, run the named harness directly, then rerun make validate before handoff. The devcontainer harness prefers Podman and uses a disposable test tag; it may visibly skip real-engine cases only when neither Podman nor Docker is installed.

Operational notes

  • CONTRIBUTING.md is the canonical local-development SOP.
  • scripts/wgm_plugin_registry.py is a proposed/unwired host-adapter helper. The portable scripts/loop.sh does not invoke plugin hooks.
  • Use temporary HOME fixtures for plugin-registry tests; never depend on or mutate the operator's real ~/.copilot/skills.
  • WSL boundary harnesses may report simulated/unverified results. Do not call them Windows-origin field evidence unless a real Windows process ran the probe.

Codebase patterns

  • Shell behavior checks live in scripts/test-*.sh, use ok:/FAIL: output, and exit nonzero on any failed assertion.
  • Test comments explain the behavior each assertion protects.
  • Prefer existing Podman-first/Docker-fallback helpers and standard-library Python; avoid new runtime dependencies.
  • Documentation changes must keep docs/README.md, CONTRIBUTING.md, and docs/reference/gates.md aligned.
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.
