Instructions file for CodexOpenCode

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

This is bahayonghang/drawio-skills's own configuration. It tells Codex and OpenCode how to work on drawio-skills 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 drawio-skills 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

drawio-skills 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 8d 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.

Repository Guidelines

Project Structure & Module Organization

skills/drawio/ is the core skill package:

  • scripts/ contains conversion and CLI logic (dsl/, math/, svg/).
  • references/ stores format specs and YAML examples used as source-of-truth docs.
  • assets/ includes theme JSON files and sample .drawio diagrams.
  • references/workflows/ defines create/edit/replicate operating guides.

skills/drawio-academic-skills/ is the publication overlay: it carries only academic policy (SKILL.md, references/docs/publication-overlay.md) and academic evals, and depends on the sibling base at ../drawio for shared CLI, references, themes, schemas, examples, and workflows.

docs/ hosts the VitePress site (with docs/zh/ for Chinese content).
tests/ holds repo-level Node tests, while module-level tests also live next to source as *.test.js.
examples/ and imgs/ provide demo artifacts for docs and validation.

Build, Test, and Development Commands

  • npm install or just install: install dependencies.
  • npm run docs:dev or just docs: start local docs server with hot reload.
  • npm run docs:build or just docs-build: generate production documentation.
  • npm run docs:preview or just docs-preview: preview built docs locally.
  • npm test or just test: run the test suite via node --test.
  • just lint: lint Markdown (markdownlint-cli).
  • just format: format Markdown (prettier).
  • just ci: run lint + tests (closest local CI check).

GitHub Actions use Node 20; keep local Node aligned when possible.

Coding Style & Naming Conventions

Use ESM JavaScript with 2-space indentation, single quotes, and existing project style (minimal semicolons).
Prefer small, composable functions for parsing and transformation logic.
Do not hide failures with silent fallbacks; throw explicit errors for invalid input.
Use kebab-case filenames (for example, spec-to-drawio.js) and *.test.js for tests.

Testing Guidelines

Use Node’s built-in testing stack: node:test and node:assert/strict.
Add or update tests for every behavior change in DSL parsing, math typesetting, and XML/SVG conversion paths.
Keep tests deterministic; store fixtures close to the related module or in tests/.

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.
