What is skill-planning?

A planning skill for designing audio plug-ins, which are programs that process or generate sound inside music software. It reads a creative brief and parameter specification, then creates a technical architecture and implementation plan.

Use it to plan the plug-in’s sound-processing blocks, parameters, architecture, and development work.

It gives an audio project a defined structure before development starts. It also records the expected complexity and the strategy for building the plug-in.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00020	$0.00062
Opus 5.5	$0.00008	$0.00025
Sonnet 5.5	$0.00004	$0.00012

Security

Grade A, and why

skill-planning 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 1mo 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.

Origin

This is a copy

100% identical to plan — 10 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.

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.
