A tool for examining a live web app with Playwright, a browser-automation tool, and turning what it finds into a product requirements document. The document includes larger work areas, user stories, priorities, and dependencies, and can be exported to Notion.

Use it to scan a web app, create a product development plan from its current features, and send that plan to Notion after checking the required connections.

It helps document an existing app's features without manually inspecting every page and writing the plan from scratch.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00043	$0.04789
Opus 5.5	$0.00017	$0.01916
Sonnet 5.5	$0.00009	$0.00958
Haiku 4.5	$0.00004	$0.00479

Security

Grade A, and why

web-to-prd 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 2mo 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 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.
