Optional AAX support for Pulp, including developer-supplied Avid SDK setup, CMake enablement, DigiShell/AAX Validator workflows, and local AAX builds on macOS or Windows.

Android platform development for Pulp — NDK cross-compilation, Oboe audio, Dawn/Skia GPU rendering, JNI bridge, touch interaction, emulator workflows, end-to-end smoke validation (#337). Covers build, deploy, debug, and the gotchas discovered during bringup.

Optional ARA support for Pulp, including developer-supplied ARA SDK setup, CMake enablement, adapter companion APIs, validation, and ARA-aware plugin implementation guidance.

Prove and debug what a Pulp processor actually emits — the audio observability harness (signal generators, metrics, assertions, RenderScenario, effect contracts) plus the offline Audio Doctor analyzers (magnitude/frequency response, THD/THD+N). TRIGGER on phrases like "is there sound / no audio / I hear nothing", "does this filter/compressor/synth/delay produce the right signal", "prove the DSP / prove the contract", "measure the frequency response", "what's the THD / is it distorting / alias...

Audio Unit v2 adapter work for Pulp — picking the right AU component type (aufx/aumf/aumi/aumu), wiring MIDI input, and avoiding the DAW-side component cache that silently masks repackaging.

Audio Unit v3 (AUAudioUnit) format adapter for Pulp — render-block wiring, parameter tree bridging, MIDI / sysex via AURenderEvent, sidechain pulls, state persistence, iOS extension surface, and the pitfalls discovered while wiring the adapter.

Local and cloud CI for Pulp — validate branches, create PRs, merge on green. Handles "push to main", "ship this", "run CI", "check PR", and "list PRs".

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

Checklist and decision tree for adding, modifying, or removing CLI commands. Keeps CLI source, slash commands, docs, and skills in sync.

Use Pulp's MIT-safe Cmajor support lane via source-owned patches, an external `cmaj` toolchain, and explicit generated-artifact workflows.

Query, recommend, and switch the Pulp JS engine backend (QuickJS, JavaScriptCore, V8). Handles "which JS engine", "switch to V8", "engine for Three.js".

Create FAUST DSP plugins in Pulp using offline codegen, pre-generated C++ headers, and the FaustProcessor template wrapper.

Load, run, and test VST3 / AU / CLAP / LV2 plugins from Pulp code. Use when working on `core/host/` (scanner, plugin_slot, signal_graph), when adding a new format backend, when wiring a plugin into a SignalGraph, or when writing an integration test that needs a real plug-in binary.

Import designs from Figma, Stitch, v0, Pencil, React Native, or Claude Design into Pulp web-compat JS with automated visual validation. Claude Design imports also scaffold a pulp::view::EditorBridge handler file (pulp #709). Versioned (parser-version / format-version / compat-schema-version) detection lives behind `--detect-only` and `--report-new-format` (pulp #1031).

iOS platform development for Pulp — iPhone/iPad AUv3 app extensions, iOS Simulator builds, UIKit window host, CoreAudio IO audio, touch & Apple Pencil input, XcodeBuildMCP automation. Covers configure, build, deploy to simulator/device, and the gotchas discovered during iOS bringup.

Work in Pulp's bounded JSFX lane using source-only examples, subset validation, and explicit exclusions like no `@gfx`.

Debug or validate Pulp animations / transitions / scroll behavior using the runtime motion-trace system. TRIGGER on phrases like "animation is wrong", "transition timing off", "fade too late", "card slides too far", "scroll jumps on restore", "scroll offset wrong on restore", "frame jump in the timeline", "easing looks wonky", "imported Figma motion doesn't match source", "settle time / overshoot / drift / monotonic", "what value does the knob reach at frame N", "record this animation so I ca...

Build an MPE-aware Pulp synth — opt into MPE via PluginDescriptor, consume per-note pitch bend / pressure / timbre from MpeBuffer, and route voices through MpeVoiceAllocator without reinventing channel tracking.

Search, suggest, add, and browse third-party audio packages. Handles "suggest packages", "add a package", "what packages are available", "search for pitch detection", and package browsing.

Leveraged-prototype dev loop (`pulp loop`) — single-platform iteration with AOT analyzer, ar-swap, and PR-state monitor. Use when porting an existing UI/bundle to Pulp, doing visual/behavioral parity work, or batching upstream framework gap fixes.

Capture faithful PNGs of Pulp view trees / imported UIs headlessly. Covers render_to_png backends (Skia vs CoreGraphics), the image-compositing gotcha, capture_png from a live GPU host, and the --screenshot-backend validate flag. Use whenever you render a UI to a PNG to eyeball or montage it.

Work with Pulp's SDF / MSDF / PSDF glyph atlases — building, sampling via SkSL, and the shared text-layout helpers.

Sign, notarize, package, and distribute Pulp plugins and apps across macOS, Windows, and Android

Pick the right Pulp Stream for a given I/O task, wire async callbacks correctly without deadlocking the worker, and avoid the backpressure / cancellation footguns in `pulp::runtime::AsyncStream`.

Stand up a fast, cached, isolated, disposable macOS CI lane on Tart — layered golden VM images, ephemeral per-job GitHub Actions runners, host-mounted caches, and a reusable per-repo vm-image manifest. Use when setting up VM-based CI for Pulp or generalizing it to another repo, building/refreshing golden images, wiring ephemeral runners, or debugging the VM lane.

Build or iterate on Pulp's native Dawn-backed Three.js workflow using the real three.webgpu.js renderer, focused bridge tests, and native demo capture.

Guide users through `pulp upgrade` — discover new CLI releases, interpret migration notes for the hop they're performing, and apply breaking-change fixes (CMake macro renames, API surface changes, config file moves). Handles "upgrade pulp", "what's new", "migrate my project", "show breaking changes", and the `/upgrade` slash command. Pairs with the embedded migration index shipped in the CLI binary (release-discovery Slice 3, #571).

Editor lifecycle and multi-view attach for Pulp plugins — when to override Processor::create_view(), the open → notify_attached → resize → close protocol, release_view() ownership rules, and secondary-view roles.

VST3 format adapter for Pulp — SingleComponentEffect wiring, bus arrangement negotiation, parameter / MIDI event routing, state round-trip, and the pitfalls discovered while wiring the adapter against Steinberg's SDK.

Build or iterate on a Pulp WebView UI using the native WebView bridge, embedded assets, directory-backed dev resources, and focused WebView validation.
