Was macht legends-obs-kit?

Use the bundled CLI as the source of truth. The runtime spine is OBS WebSocket v5; FFprobe and the OBS log provide recording proof.

Resolve and qualify

Resolve the command in this order:

1. Use lobs or legends-obs-kit when it is available on PATH.
2. If this skill is linked from a repository or extracted release, move two directories up from SKILL.md and run node <root>\dist\index.js.
3. In a developer checkout without dist, run pnpm dev -- from the repository root.

If none exists, tell the user to install the complete release or repository. Do not invent an OBS control backend. In the examples below, lobs means whichever resolved invocation is available.

lobs doctor --pretty
lobs manifest --pretty
lobs agent:context --pretty
lobs audit:status --pretty

doctor hard-gates authenticated local OBS control. Encoder, HDR, FFprobe, recording-path, and microphone checks are capabilities unless the requested operation needs them. If FFprobe is not on PATH, set LEGENDS_OBS_FFPROBE_PATH to its executable.

If the machine has no ledger, run audit:capture --reason first-baseline. If a ledger exists, run audit:diff --against good; use --against latest until the first passing canary creates a known-good pointer.

Route by intent

Intent	Commands
Health and live state	doctor, status, record:status
Machine, profile, scenes, and sources	inventory, profile:show
Audio endpoint	audio:status, audio:plan, audio:bind
Settings history and drift	audit:status, audit:capture, audit:show, audit:diff, audit:verify
Profile change	profile:plan, profile:backup, profile:apply, profile:refresh, profile:rollback
Local recording	record:start, record:stop, record:canary
Evidence	logs:latest, receipts:list, receipts:verify
Optional panel scene switcher	vision-switch:*

Read references/command-map.md for the compact command and safety map.

Default output is privacy-minimized for agent use. inventory --full, audio:status --include-devices, audit documents, and local receipts can include machine paths, source names, endpoint IDs, window titles, and other workstation facts; keep them local unless the user explicitly asks to share them.

Mutation rules

1. Read current state and produce a plan first.
2. Verify recording, streaming, replay buffer, and virtual camera are idle.
3. Keep LEGENDS_OBS_DRY_RUN=true by default.
4. For one authorized write, set it to false, pass --confirm, perform one bounded mutation, and restore dry-run in finally.
5. Every profile inspection, plan, backup, apply, or refresh and every record:canary requires an explicit --preset <id>; bundled presets are never selected as a user recommendation.
6. Profile apply snapshots before writing, refreshes only when necessary, and verifies exact readback.
7. Never print or copy the OBS WebSocket password or OBS service credentials.
8. Never call a recording WORKS without a passing canary receipt.
9. Treat latest as last observed, not proven. Only a passing canary advances last-known-good.
10. Use --require-microphone only when microphone capture is part of the user's acceptance criteria.

Hardware decisions

Do not treat any bundled preset as universally correct. Inspect available encoders, current resolution/FPS, color format, display path, storage, audio needs, and target platform. Explain tradeoffs, run profile:plan, and let the user's requested outcome select the preset.

The bundled hdr-4k60-av1-hybrid-mp4 preset is a tested reference for capable NVIDIA hardware: 3840×2160/60, P010, Rec.2100 PQ, limited range, Standard NVENC AV1, Hybrid MP4, CQP20 or better, two-second keyframes, single pass, and no rescale. It is not a default recommendation for other systems.

Optional Vision Switcher

The deterministic panel-to-scene switcher is disarmed and dry-run by default. Supply panel samples with --panel A|B|C|D or set LEGENDS_OBS_PANEL_SENSOR to a PowerShell script that emits the documented JSON shape. Live cuts additionally require an armed state, idle outputs, LEGENDS_OBS_DRY_RUN=false, and --confirm. The cut loop never uses an LLM and never changes Windows display mode.
