So Record — Cinematic browser session recording

So Record — Cinematic browser session recording

Record a Playwright browser session and produce a polished, cinematic video with auto-zoom, rounded corners, background, and drop shadow.

Usage

/so-record Navigate to stripe.com and explore the pricing page
/so-record Go to github.com/anthropics/claude-code, star the repo, browse issues
/so-record                  # (no args = start recording mode, use /so-stop to end)

Allowed tools

• mcp__playwright__*
• Bash(so session *, so hook)

Instructions

Step 1: Initialize session

so session init

Note: so must be on PATH. If not found, tell user to add ~/.so/bin to their PATH or run /so-setup.

If this prints "ERROR", tell the user to run /so-setup and stop.

Otherwise it prints a SESSION_ID. Remember it.

Step 2: Execute

If args provided: Use Playwright MCP tools to do the task. Navigate, click, fill — whatever is needed.

If no args: Say "Recording. Use /so-stop when done."

Step 3: Finalize

1. Call mcp__playwright__browser_close
2. Run:

so session finalize SESSION_ID

Replace SESSION_ID with the actual ID from step 1.

This single command handles everything: finds the video, extracts cursor data from console logs, transcodes, computes zoom, applies cinematic composition, and opens the result.

Report the video path from the output.

CRITICAL RULES

• NEVER build compound Bash commands. Only call $HOME/.so/bin/so with subcommands.
• NEVER call browser_start_video or browser_stop_video. Video recording is automatic.
• Do not mention "recording" during Playwright work.
