Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00084 | $0.00384 |
| Opus 5 | $0.00042 | $0.00192 |
| Sonnet 5 | $0.00017 | $0.00077 |
| Haiku 4.5 | $0.00008 | $0.00038 |
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 7d 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.
This is a copy
100% identical to mixer-scene-contract — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
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.tssrc/automation/showDirectorRuntime.tssrc/cli/agent.tsaroundshow-directortests/unit/showDirector.test.tstests/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, orsetlist_ref. Do not design fuzzy live lookup as execution. - Preserve blocked/operator-only semantics for
mixer_gain,pa_mute, andaudio_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:
- proposed schema fields and examples;
- approval and audit model;
- CLI dry-run examples;
- mapping to action plans;
- compatibility notes;
- 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.
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.

mixer-scene-contract is a skill published in the GitHub repository hybridlabor-api/bdb-dev-optimized-agent-skills (6 stars, last pushed 5d ago), licensed Apache-2.0. It adds 84 tokens to every session and 384 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to mixer-scene-contract, differing in 0 lines, and is treated as a copy.
