README

Excerpt

How Libretto Read-Only Works

Use this skill when the browser session must stay strictly read-only.
Libretto stores read-only vs write-access on the session itself.
The primary inspection tools are snapshot and readonly-exec.
readonly-exec reuses Libretto's normal execution pipeline, but it only exposes read-only helpers and denies mutating Playwright methods.
Only a user can change the session mode for an existing session. Never change a session's mode on your own — the user must change it themselves manually.
