ClawCast

Bootstrap and automate OBS scenes for local or remote instances via agentic-obs + mcporter. Includes optional explicit target-switch step that writes agentic-obs DB config only when acknowledged with a cross-component-write flag. Use when an OpenClaw agent needs to create a reusable baseline scene pack, wire browser/media sources over LAN-safe HTTP, run recording/stream smoke tests, and provide a clean starting point for project-specific customization.

Use this skill to create a generic, reusable OBS automation baseline.

Prerequisites

• mcporter installed/configured with obs MCP server
• OBS WebSocket enabled on target OBS host (default 4455)
• python3, sqlite3, ss (iproute2), and standard shell tools

Prerequisite 0 (required): verify obs MCP path

bash

mcporter list
mcporter call 'obs.get_obs_status()'

If this fails, stop and finish mcporter + OBS MCP configuration first.

Workflow

1. Switch target OBS host
2. Start overlay HTTP server
3. Rebuild baseline scene pack from skill assets
4. Optionally apply transition + audio defaults
5. Run recording smoke walkthrough
6. Optionally run stream dry-run

Commands

bash

# 1) Target OBS host (explicit write acknowledgement + DB path required)
./skills/clawcast/scripts/obs_target_switch.sh <obs-host-ip> 4455 \
  "$HOME/.agentic-obs/db.sqlite" --allow-cross-component-write

# 2) Start/verify overlay host server (serves skill directory only)
./skills/clawcast/scripts/start_overlay_server.sh

# 3) Rebuild baseline scenes + overlays
./skills/clawcast/scripts/rebuild_scenes.sh

# 4) Apply transition preset
./skills/clawcast/scripts/apply_transition_preset.sh Fade 300

# 5) Optional audio baseline
# export OBS_AUDIO_INPUTS="Mic/Aux,Desktop Audio"
./skills/clawcast/scripts/apply_audio_baseline.sh

# 6) Run walkthrough recording
./skills/clawcast/scripts/smoke_test_walkthrough.sh

# 7) Optional stream dry-run
./skills/clawcast/scripts/stream_dry_run.sh 15 "Intro" "Main Live"

Notes

• This skill is boilerplate-first; customize scenes and assets after bootstrap.
• Baseline-required overlays live in assets/overlays/.
• Optional project-specific examples live in examples/project-specific/.
• Avoid /tmp for persistent assets.
• For remote OBS, prefer HTTP browser source URLs over file://.

Security & transmission

• No API keys/tokens are required by default for this skill.
• OBS control uses the configured WebSocket endpoint (default port 4455).
• Overlay pages are served over local HTTP (:8787) and should remain on trusted LAN/VPN.
• start_overlay_server.sh serves only the skill directory (not workspace root).
• obs_target_switch.sh performs a cross-component config write only when given an explicit DB path argument plus --allow-cross-component-write.
• Do not expose OBS WebSocket or overlay HTTP ports publicly.
