bpmn-generator: Instructions file for Codex

AGENTS.md

bpmn-generator AGENTS.md is an instructions file for Codex, OpenCode from Stieges/bpmn-generator. It costs 283 tokens per session, scanned A, original, MIT.

Repository instructions for a BPMN generator, a tool that creates and works with BPMN 2.0 process diagrams. They describe running its demo, configuring an API key, and using its preloaded examples.

In plain words
What is it for?
Use them when developing, testing, or demonstrating the BPMN generator and its browser-based copilot.
Why use it?
They give an agent the project-specific steps and settings needed to run and work on the repository without guessing.

Instructions file for CodexOpenCode

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

This is Stieges/bpmn-generator's own configuration. It tells Codex and OpenCode how to work on bpmn-generator 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 bpmn-generator 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

bpmn-generator 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 1mo 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

BPMN Generator for Agents & opencode

This repository provides tools for autonomous agents to generate, validate, and manipulate BPMN 2.0 XML files.

Demo

Run the BPMN Copilot demo:

cd scripts
npm install   # one-time, ~30s
npm run demo

This starts the HTTP server on http://localhost:3000 and serves the frontend. Open your browser to that URL.

API key

For the LLM chat to work, you need an OpenAI-compatible API key. The frontend will prompt you for it when you first click "Custom Text". The key is stored in localStorage (browser only — never sent to disk on the server side).

If you prefer to pre-configure the key, set OPENAI_API_KEY in your shell before running npm run demo. The server then uses it as a fallback for all LLM calls, so requests work even without a key entered in the browser. (The backend also exposes GET /api/v1/config, reporting envKeyConfigured, so a frontend can detect this and skip the modal — wiring that into the UI is a separate step.)

Pre-loaded examples

Click any of the four example cards on the start screen — no key needed. The BPMN is pre-generated and rendered instantly.

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.
