deepmind-parameter-guide

Reference instructions for designing sounds on the DeepMind 12 synthesizer, an electronic instrument. They explain how its controls interact and how parameter changes affect the sound.

In plain words
What is it for?
Creating sounds, exploring oscillator, filter, envelope, LFO, modulation, arpeggiator, and related synthesizer settings.
Why use it?
They add musical context that parameter tools alone may not provide, helping an agent make informed sound-design choices.

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

deepmind-parameter-guide 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 yesterday.

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.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

MCP note: describe_param returns ranges, units, and enum labels for any parameter. set_param/set_params accept value (0..1), rawValue, or label. This skill focuses on the why and what it sounds like — things the tools can't tell you.

Start with recipes.md for complete sound-design examples, then read individual sections for deeper context on a specific area.

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.

deepmind-parameter-guide is a skill published in the GitHub repository truthanb/patchwork-deepmind (2 stars, last pushed 3mo ago), licensed MIT. It adds 45 tokens to every session and 1,546 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
