Miri is the cheapest sound UB detector for Rust; this skill wraps it with the right isolation flags for audio DSP crates. - [Audio Fft Sanity](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-audio-fft-sanity) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-audio-fft-sanity` FFT-based sanity check for audio output files — verifies fundamental frequency, THD, SNR, clipping, and silence. Use after offline C tests or WASM OfflineAudioContext captures to confirm a signal chain is producing correct output. - [Wasm Module Inspect](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-wasm-module-inspect) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-wasm-module-inspect` Inspect a compiled .wasm binary — validates structure, lists exports and imports, detects SIMD and threading opcodes, and reports binary size. Requires wabt; wasm-opt (Binaryen) is optional. - [Faust Header Gen](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-faust-header-gen) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-faust-header-gen` Generate a matching extern "C" header from a Faust-generated C file. Extracts public function signatures, applies the opaque-typedef pattern, and emits a correctly guarded header. Eliminates the manual header maintenance step and prevents header/implementation drift. - [Wasm Pack Build](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-wasm-pack-build) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-wasm-pack-build` Opinionated wasm-pack wrapper that builds a Rust crate to wasm32-unknown-unknown with project-pinned flags (SIMD, LTO, panic=abort), applies a wasm-opt post-pass, and auto-invokes wasm-module-inspect on the result. Single entry point so the agent never reaches for raw wasm-pack and forgets a flag. - [Rust Rt Audit](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-rust-rt-audit) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-rust-rt-audit` Audit a Rust DSP crate for real-time-safety violations — verifies `#![no_std]`, no `alloc` dependency, `panic = "abort"`, runs targeted clippy lints, greps for banned constructs in the hot path, and scans the compiled LLVM-IR for allocator symbols. Designed to be run on any Rust DSP crate before merge. - [Dembrandt](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-dembrandt) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-dembrandt` Extract design tokens from any live website using the Dembrandt CLI, and save them in W3C Design Tokens (DTCG) format. Use when you need to inspect or borrow a site's design system. - [Log Pattern Scan](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-log-pattern-scan) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-log-pattern-scan` Scan Claude Code JSONL session transcript files for behavioral patterns — loops, errors, expensive turns, trial-and-error signatures. Returns structured findings for the improvement-analyst agent. - [Emscripten Env Audit](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-emscripten-env-audit) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-emscripten-env-audit` Static analysis of Emscripten build flags targeting AudioWorkletGlobalScope. Parses a Makefile or build script, extracts emcc flags, and cross-references against a known list of APIs unavailable in the worklet environment. Flags configuration patterns that will cause runtime failures in the browser. - [Wasm Worklet Smoke](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-wasm-worklet-smoke) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-wasm-worklet-smoke` Headless Playwright smoke test for an Emscripten + AudioWorklet WASM build. Builds the WASM target, serves it locally, launches headless Chrome, clicks Start Audio, verifies the engine initialises without console errors, and checks for non-silent audio output. - [Faust Build](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-faust-build) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-faust-build` Compile a Faust DSP source file to C, verify the API surface (function names, I/O counts, struct name), and optionally compile the result with clang. Runs a parameter smoothing audit before compilation. Use after any change to a .dsp file. - [Cbindgen Verify](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-cbindgen-verify) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-cbindgen-verify` Regenerate a C header from a Rust crate via cbindgen and diff it against the committed header. Fails if the generated output differs — catches "Rust signature changed but the C header was not regenerated" before it reaches the C side. - [Cargo Bench Rt](https://agentstack.voostack.com/l/skill-gertsylvest-meta-team-cargo-bench-rt) — Skill · Free · security-reviewed — `agentstack add skill-gertsylvest-meta-team-cargo-bench-rt` Run a Criterion benchmark on a Rust DSP crate and assert against a checked-in baseline. Establishes whether the implementation fits the real-time budget and catches performance regressions — the Rust equivalent of `perf stat` against the audio buffer time. --- Seller on AgentStack — the marketplace for AI agent skills and MCP servers.
