actant-studio

Local UI + CLI for Actant. Ships the actant binary.

npx actant studio                                # open the local UI
actant approve <tool_call_id> --scope once
actant deny    <tool_call_id> --reason "out of policy"
actant replay run <event_id> --without-memory mem_42
actant replay diff <run_a> <run_b>

What Studio shows

Per /examples/test-cleanup/README.md:

• Timeline. Every captured event: model call, tool call requested, guard verdict, approval, tool result, context build, observation.
• Context manifest detail. What was included, what was blocked, why.
• Approval drawer. Approve / deny / constrain a pending tool call. The constrained variant is recorded.
• Replay control. Pick an event, choose overrides (policy, memory exclusion, alternate model), run, see the side-by-side diff.

That is the scope for v0.1. Anything more is post-Gate-3.

Tech

• React 19 + TypeScript strict.
• Vite for the UI bundle.
• Local Node HTTP server hosts the bundle + a websocket to @actantdb/core's ledger.
• No remote backend. No telemetry leaving the machine by default.

Status

Pre-alpha. The Studio surface is the visible part of the killer demo and the validation tests. If the demo doesn't make sense in Studio, the demo is broken.
