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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.02975 | $0.02975 |
| Opus 5.5 | $0.01190 | $0.01190 |
| Sonnet 5.5 | $0.00595 | $0.00595 |
| Haiku 4.5 | $0.00298 | $0.00298 |
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 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.
How it starts
The opening of the file, as written. The whole thing — 161 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.
Commands
| Task | Command |
|---|---|
| Install | npm install — Node 20+, system Chrome, ffmpeg+ffprobe on PATH (no Playwright browser download) |
| Type check | npm run typecheck |
| Fixture server | node examples/local-demo/serve.mjs (port 8787) |
| E2E smoke test | node bin/aidemo.mjs render examples/local-demo --headless |
| Dry-run actions only | node bin/aidemo.mjs probe examples/local-demo --headless |
| Resume a take | node bin/aidemo.mjs record <dir> --from-scene <id> (also render, MCP fromScene) — reuses the previous take's earlier scenes (hash-guarded), replays their actions fast, records from <id> |
| Draft from a Playwright trace/test | node bin/aidemo.mjs import-trace <trace.zip|spec.ts> --name <demo> — actions + selectors → scenes, no LLM (MCP import_trace) |
| Draft from a URL | node bin/aidemo.mjs init <name> --from-url <url> — inspect first, headings → scenes, unique selectors → beats (MCP init_demo {fromUrl}) |
| Selector discovery | node bin/aidemo.mjs inspect <url> --dir <demo> — unique selectors per visible element (MCP inspect job); the same scan writes logs/drift-*.json suggestions when a take's selector matches nothing |
| Validate a storyboard (no browser) | node bin/aidemo.mjs validate <dir> (--file <path>, --json; non-zero exit on issues) |
| Lint / pacing forecast (no browser) | node bin/aidemo.mjs lint <dir> (--lang, --json, --strict) — also auto-runs in probe/record/render; measured counterpart is output/report.json from compose |
| Frames for review | node bin/aidemo.mjs frames <dir> --every 3 (--source raw for the take) |
| Walkthrough bundle | node bin/aidemo.mjs walkthrough <dir> — output/walkthrough/ (index.html, guide.md, frames, captions) from the final video (also auto in render with output.walkthrough) |
| One pipeline stage | node bin/aidemo.mjs voice|record|captions|compose <dir> |
| Screenshot stills | node bin/aidemo.mjs stills <dir> — extract named PNGs from an existing take (also auto-runs in render when the storyboard has still markers) |
| Golden regression check | node bin/aidemo.mjs probe <dir> --update-golden (write baseline) / --golden (CI guard, non-zero exit on drift) |
| Multi-language matrix | node bin/aidemo.mjs render <dir> --langs de,fr — one take → N locales (also --lang on voice/captions/compose) |
| Personalized variants | node bin/aidemo.mjs render <dir> --variants variants.json (or --param k=v) |
| Always-fresh embed snippets | node bin/aidemo.mjs embed <dir> — stable raw-GitHub URLs for READMEs/PRs |
| CI render (consumers) | uses: tandryukha/aidemo@stable (composite action, action.yml) — see docs/CI.md |
| MCP server (agent interface) | node bin/aidemo.mjs mcp — stdio; smoke test: npm run mcp-smoke (needs Chrome) |
| Print authoring guide | node bin/aidemo.mjs guide (--topic core|schema|attention|polish|…, --list) |
| Environment check | node bin/aidemo.mjs doctor |
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.

aidemo AGENTS.md is an instructions file published in the GitHub repository tandryukha/aidemo (20 stars, last pushed 7d ago), licensed MIT. It adds 2,975 tokens to every session, about $0.0119 per session on Opus 5.5. 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 2026-08-31.
