Fastbrowse documents broader trace redaction and optional action-choice records
Version 0.9.1 extends redaction across recorded steps and trace strings, and adds optional offered-control records.
Why it matters
Inspecting available controls can explain wrong choices, while trace redaction matters when runs use credentials.
What to watch
Independent replay-redaction checks and failure analyses using recorded choices.
Still uncertain. Release-note claims were not tested; the action classifier remains fallible.
Impact assessment reviewed 2026-10-31.
- Who it helps
- Developers inspecting browser-agent decisions and completion evidence.
- Availability
- Public MIT project and paid hosted service. October 30 version 0.9.1 release notes were checked; no agent run was executed.
The action loop
Jev, the decision model, selects an operation and target from page controls. A larger language model plans the task or reads longer passages. Completion checks use captured evidence and quotes.

What changed in 0.9.1
The changelog describes redacting secrets throughout step and trace records, plus an optional list of controls offered to the model. That list can help explain a wrong target choice.

Where the evidence stops
The irreversible-action classifier can miss actions. Documentation and demonstration descriptions were read; safety, speed and cost were not independently tested.
