legax AGENTS.md

Project rules for AI coding assistants working on Legax, a dependency-free Node.js application configured with YAML. They define how code, documentation, process coordination, MCP tools, and security boundaries must be handled.

In plain words
What is it for?
Guiding code changes, configuration edits, documentation updates, MCP integrations, process coordination, and reviews in the Legax repository.
Why use it?
They keep changes consistent with the project’s architecture and prevent unsafe shortcuts such as bypassing approval prompts or running arbitrary remote commands.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

legax 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 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.

The opening of the file, as written. The whole thing — 50 lines — stays where its author put it; the contents beside it link to each section on GitHub.

English | Simplified Chinese

This is the repository instruction contract for AI coding agents working on Legax. Start here, then read Context For LLMs. Do not load every document by default.

Hard Rules

  • Keep the project dependency-free: Node 18+ standard library only, no bundler, and no new npm dependency unless the design has been accepted.
  • Keep configuration YAML-only. Use scripts/lib/yaml.mjs; do not add JSON config support or a YAML dependency casually.
  • Keep cross-process daemon and adapter coordination in scripts/lib/runtime-state.mjs; do not create sibling state files for cursors, selected sessions, modes, or launch requests.
  • Keep MCP as a capability layer. MCP tools may notify, poll, or request permission, but must not start or stop adapter processes.
  • Never simulate UI clicks, auto-approve native prompts, or bypass an agent's security policy.
  • Do not route remote workflow input to arbitrary shell, eval, script, prompt, command, or free-form executable args.
  • Keep documentation language pairs together: English .md with .zh-CN.md, and config.example*.yaml with matching config.example*.zh-CN.yaml.
  • Keep tracked documentation and commented examples UTF-8 without BOM; do not rewrite them through locale-dependent shell encodings.
  • Do not commit implementation plans, drafts, scratch notes, audit notes, or agent transcripts as tracked docs. Use ignored process directories or external task systems.
  • If you add a script or E2E file, append it to the explicit package.json check:node or test:e2e list.

Context Loading

  • Read docs/context_for_llms.md for the task routing table and canonical owners.
  • Default to English docs. Load .zh-CN pairs only for translation, Chinese documentation work, or pair consistency checks.
  • English docs are the canonical contract. Chinese docs are localized mirrors; if they diverge, follow English and update both.
  • For non-trivial code changes, use the smallest task-specific context set from docs/context_for_llms.md, then use docs/CHANGE_MATRIX.md for focused verification.
  • If docs conflict with this file, stop and surface the conflict before editing.

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.

legax AGENTS.md is an instructions file published in the GitHub repository zhanex/legax (11 stars, last pushed 2mo ago), licensed MIT. It adds 690 tokens to every session, about $0.0034 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
