What is guide-from-screenshots?

A documentation tool that turns a folder of screenshots and an explanation into a structured Markdown guide. Markdown is plain text with simple formatting rules, and Notion is a workspace for notes and documents.

Creating product, demo, or tool guides from screenshots, filtering duplicate captures, adding image placeholders, and producing a Notion-compatible Markdown file.

It removes the work of sorting screenshots, deciding which ones matter, and arranging them into a readable guide.

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	$0.00073	$0.01961
Opus 5	$0.00036	$0.00981
Sonnet 5	$0.00015	$0.00392
Haiku 4.5	$0.00007	$0.00196

Security

Grade A, and why

guide-from-screenshots 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 11d 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.
