mixer-scene-contract

mixer-scene-contract is a skill for Claude Code from lucasmaher-hash/touch-designer-mcp. It costs 84 tokens per session (384 once invoked), scanned A, a copy of mixer-scene-contract, MIT.

A design guide for defining structured requests for mixer scene changes in an AI-controlled party system. It covers the request schema, human approval, audit records, command examples, and tests.

In plain words
What is it for?
Use it to design scene and cue data, approval states, audit entries, dry-run commands, action-plan mappings, compatibility notes, and unit tests.
Why use it?
It keeps mixer changes separate from general effect controls and makes each request traceable. It also keeps risky operations such as gain, muting, and audio routing restricted to operators.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

mixer-scene-contract scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

mixer-scene-contract

Design the structured contract for approved mixer scene changes. This skill is for design/spec work, not implementation.

Context to read

  • src/automation/showDirectorSchema.ts
  • src/automation/showDirectorRuntime.ts
  • src/cli/agent.ts around show-director
  • tests/unit/showDirector.test.ts
  • tests/unit/cliAgent.test.ts

Design rules

  • Keep mixer scene changes separate from generic arm_effect.
  • The MVP operation is "arm scene/cue for approval", not autonomous execution.
  • Require explicit names or IDs: show_name, snapshot_name, cue_name, scene_id, or setlist_ref. Do not design fuzzy live lookup as execution.
  • Preserve blocked/operator-only semantics for mixer_gain, pa_mute, and audio_routing.
  • Every accepted request needs an audit entry with request, intent, decision, approval ID, operator, and adapter target.

Output

Write _workspace/ai-party-mixer/01_contract.md with:

  1. proposed schema fields and examples;
  2. approval and audit model;
  3. CLI dry-run examples;
  4. mapping to action plans;
  5. compatibility notes;
  6. unit-test checklist.

Quality bar

The result should be specific enough that a builder can implement it without asking what fields exist or how approval flows.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
