Browser Demo Recorder

Turn a natural-language recording request into a deterministic browser recording that lands in the current workspace media/ directory and can be sent back immediately.

Workflow

1. 1. Extract the recording brief into a concrete sequence.
2. Convert the sequence into a JSON plan.
3. Run scripts/run-recording.mjs against that plan.
4. Verify the MP4 exists in the current workspace media/ directory.
5. Reply with a short status line and a MEDIA: line pointing at the generated file.

What to Capture From the User Brief

Convert the request into these fields before recording:

• - Start URL and any required destination URLs
• Viewport preference if given; otherwise use INLINECODE4
• Ordered steps: page holds, cursor sweeps, clicks, typing, scrolls, and ending frame
• Timing goals: total duration, per-step hold times, and any "don't click" / "hover only" constraints
• Output basename if the user hints at a name; otherwise derive a short slug from the task

If the brief is missing something critical, ask one question. Otherwise infer sensible defaults and proceed.

Plan Format

Read references/plan-schema.md when building or debugging plans.

Use references/example-skills-video-plan.json as the default reference for a multi-step marketing demo with homepage, hub, search, and return-home flow.

Runner

Run the recorder like this:

CODEBLOCK0

Behavior:

• - Connects to the existing OpenClaw browser via CDP
• Injects a visible cursor overlay so recordings show mouse position
• Uses human-like mouse movement, clicks, typing, and wheel-based scrolling
• Records directly to MP4
• Writes both MP4 and debug JSON into the plan's INLINECODE7
• Default output directory should be the current workspace media/ directory

Output Rules

Always set the plan outputDir to the workspace media directory unless the user explicitly asks for a different safe location.

After success:

1. 1. Mention the generated file path briefly.
2. Put the attachment on its own line using the MEDIA protocol.

Example reply shape:

CODEBLOCK1

Use a workspace-relative MEDIA: path when possible.

Implementation Notes

• - Homepage forms sometimes open a new tab; if that breaks a continuous recording, add an evaluate step that changes the form target to _self before clicking submit.
• Prefer DOM-based targets over raw coordinates, but use coordinates for cinematic cursor sweeps.
• Keep cursor motion smooth and leave short holds after major transitions so the video is usable with voiceover.
• Save the generated plan near the media output or in a temp location only if you need to inspect it again; the MP4 in media/ is the primary artifact.
• If the run fails, inspect the debug JSON written next to the output video before retrying.
