clap

clap is a skill for Claude Code, Codex from Generous-Corp/pulp. It costs 46 tokens per session (13,990 once invoked), scanned A, original, MIT.

CLAP format adapter for Pulp — how Processor bridges to clapplugint, how parameters / modulation / sidechain / MPE / UMP / sysex flow, and the pitfalls discovered while wiring the adapter.

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

clap 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.

CLAP Skill

Use this skill when touching Pulp's CLAP adapter, when answering questions about how a Pulp plugin appears to a CLAP host, or when a CLAP validator run surfaces something odd. CLAP is Pulp's first-class, MIT-safe plugin format — every plugin built with Pulp ships a CLAP binary and CLAP is the fastest iteration lane because the clap-validator runs without a DAW.

When to use

  • Editing core/format/src/clap_adapter.cpp or the generated entry header core/format/include/pulp/format/clap_entry.hpp (the boilerplate- generator macro PULP_CLAP_PLUGIN(…)).
  • Adding or changing a CLAP extension (audio-ports, note-ports, params, state, gui, preset-load, ARA companion factory, …).
  • A CLAP host reports a behaviour issue — sidechain missing, MIDI events dropped, presets not loading, GUI refusing to attach.
  • A clap-validator pass regresses.
  • Working on the MPE or UMP sidecar as it flows through the CLAP path — the CLAP adapter is currently the canonical consumer of set_mpe_input / set_ump_input.
  • Cross-referencing CLAP behaviour against VST3 / AU when debugging host-specific regressions — use the three adapters as each other's "oracle" during parity fixes.

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.

clap is a skill published in the GitHub repository Generous-Corp/pulp (16 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 13,990 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 2026-09-04.
