What is screenize-explorer?

Tools for exploring and debugging Screenize project packages. Screenize projects contain a project description plus recordings such as video, mouse movements, clicks, keystrokes, and interface-state events.

Use it to list projects, read project metadata, summarize event streams, display timeline segments, and inspect recording statistics.

It helps you understand a recording package and inspect what happened over time without manually opening each data file.

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	$0.00034	$0.01792
Opus 5.5	$0.00014	$0.00717
Sonnet 5.5	$0.00007	$0.00358
Haiku 4.5	$0.00003	$0.00179

Security

Grade A, and why

screenize-explorer 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.
