packages

packages is a skill for Claude Code, Codex from Generous-Corp/pulp. It costs 41 tokens per session (5,869 once invoked), scanned A, original, MIT.

A package-discovery tool for Pulp audio projects. It searches a registry of third-party audio libraries, which are reusable code packages made by other developers.

In plain words
What is it for?
Use it to search for or suggest libraries for tasks such as pitch detection, machine-learning inference, and audio resampling, then add a suitable package.
Why use it?
It helps you find missing capabilities without writing every audio feature yourself, while showing when license review may be needed.

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

packages 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 today.

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.

Package Manager Skill

Help users discover, evaluate, and add third-party audio libraries to their Pulp projects.

When to Use

  • User asks about available packages or libraries
  • User needs a capability not in Pulp's built-in signal subsystem
  • User wants to add a third-party library
  • User asks about pitch detection, ML inference, resampling, etc.
  • User says "suggest packages", "find a library for X", "what's available for Y"

Package Discovery

Search the registry for packages matching a need:

./build/pulp search "<query>"
./build/pulp search "<query>" --refresh
./build/pulp suggest --description "<what the user needs>"
./build/pulp suggest --description "<what the user needs>" --include-license-gated

pulp suggest hides packages that require license review or a commercial override by default. Add --include-license-gated only when the user explicitly wants to inspect those candidates; otherwise prefer permissive defaults.

Or read the registry directly for full details:

cat tools/packages/registry.json | python3 -m json.tool

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.
