JSFX Bounded Subset

Use this skill when a task involves Pulp's current JSFX support lane.

Truthful Position

Pulp supports a bounded audio-focused JSFX authoring lane, not full REAPER parity.

Supported now:

  • .jsfx source files
  • subset validation for @init, @slider, @block, @sample
  • slider declarations slider1..slider64
  • source-only examples that stay inside that subset

Not supported by this skill:

  • @gfx
  • file I/O
  • silent compatibility assumptions with REAPER
  • a shipped JSFX runtime/engine in Pulp core

Core Files

  • docs/guides/jsfx.md
  • tools/scripts/jsfx_subset.py
  • examples/jsfx-gain/
  • examples/jsfx-tremolo/
  • examples/jsfx-delay/

Recommended Workflow

1. Validate the file first

python3 tools/scripts/jsfx_subset.py doctor \
  --file examples/jsfx-gain/PulpJsfxGain.jsfx

Use --json when another tool or script needs structured output.

2. Stay inside the bounded subset

Allowed sections today:

  • @init
  • @slider
  • @block
  • @sample

If a file uses @gfx or another unsupported section, treat that as an explicit out-of-scope failure, not a bug in the validator.

3. Keep docs truthful

When updating this lane, keep these in sync:

  • docs/guides/jsfx.md
  • docs/reference/capabilities.md
  • docs/guides/examples.md
  • planning/v3-phase14-gap-closure-status.md

What To Check

For the current JSFX lane, verify:

  • desc: exists
  • slider declarations are sane and unique
  • unsupported sections fail clearly
  • docs do not imply full REAPER JSFX compatibility or a shipped runtime

Gotchas

  • Section directives can carry trailing arguments. REAPER documents @gfx WIDTH HEIGHT as the standard form for declaring the preferred plugin window size. Any future regex change to SECTION_PATTERN in tools/scripts/jsfx_subset.py must keep matching the @name <args> shape — anchoring to end-of-line silently lets @gfx 200 200 slip past the bounded-subset check (the exact bug the 2026-05-26 follow-up fixed). Regression coverage lives in tools/scripts/test_jsfx_subset.py::test_doctor_rejects_gfx_section_with_size_directive.

Maintain Pulp's installed design-time agent capability manifest and public-surface ledger. Use when adding, removing, renaming, or materially changing public audio, MIDI, signal, timebase, or sequence APIs; registering a new algorithm for generators; changing capability support or deprecation state; or repairing agent-capabilities freshness, schema, fingerprint, tombstone, or installed-SDK tests.

The measurement surface for ALL Pulp DSP and audio-pipeline work — read it BEFORE writing or gating DSP, not only when something already sounds wrong. Covers the C++ harness (signal generators, metrics, assertions, RenderScenario, contracts), the offline Audio Doctor (magnitude/frequency response, THD/THD+N, phase/group delay), and their Python sibling the Audio Quality Lab (tools/audio/quality-lab — null residual + alignment, LTAS log-spectral distance, spectral flux/centroid, HNR, Theil-Sen drift slope, Kaiser-sinc resampling, license-guarded corpus, regression-net ratchet). TRIGGER on AUTHORING work — "build/design an oscillator/filter/synth/effect", "add a DSP module", "what should the acceptance gate be", "how do I measure aliasing / anti-aliasing / alias floor", "null against a reference", "is this DSP correct", "choose a tolerance", "golden/regression corpus for audio", "measure drift or jitter", "A/B two renders" — AND on DEBUGGING work — "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", "what's the group delay / phase response / measured latency", "magnitude response curve", "render a test tone and assert", "audio regression", "64-frame works but 128 is silent", "sample-rate change pitch-shifted it", "describe what's in this buffer", "audio doctor", "compare before/after a DSP refactor". Reach for this BEFORE hand-rolling any FFT, null test, alias measurement, pitch tracker, or golden-render script — most of it already exists in one of the two lanes. Test/tool layer over HeadlessHost — deterministic, no audio device, no speakers. Off the realtime thread entirely.
