aidemo AGENTS.md

aidemo AGENTS.md is an instructions file for Codex, OpenCode from tandryukha/aidemo. It costs 2,287 tokens per session, scanned A, original, MIT.

Project instructions for aidemo, a tool that turns a scripted browser demonstration into a finished video. The process creates narration, records browser actions, adds word-timed captions, and assembles the final MP4 video.

In plain words
What is it for?
Use it when developing aidemo, checking types, serving the local demo, running end-to-end renders, testing browser actions, or running individual voice, recording, caption, and composition stages.
Why use it?
It gives coding agents the project's working model, required tools, commands, and rules so changes do not break the video pipeline or its ffmpeg-based editing steps.

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

aidemo 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 4d 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 — 136 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Working on aidemo — guide for coding agents

You are working on the demo engine, not just using it. The README explains what aidemo is and why it's built this way; CONTRIBUTING.md covers process (DCO sign-off, PR expectations, CI policy). If this file contradicts them, they win.

Mental model: storyboard.json (script + per-scene voice/music plan + browser action-spec) → voice (OpenAI TTS) → record (deterministic replay in real Chrome, injected cursor, timeline) → captions (Whisper word timing) → compose (ffmpeg: trim idle, sync to narration, zoom, cards, mux) → output/final-demo.mp4.

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.
