基于 SOC 职业分类
Orchestrate multi-agent engine work on orkid — decomposing milestone specs into lanes, assigning machines/branches, briefing implementer and gate-runner subagents, reviewing, adjudicating gates, and integrating. Use when coordinating subagent-based implementation of a spec/milestone rather than implementing directly.
How to author procedural content in orkid using HyperSyn (Reality Synthesizer) — a Python-as-DSL system for composing particle systems, 2D/3D procedural textures, mesh/SDF operations, and (eventually) audio/sequencer graphs into compact runtime experiences. Use when the user asks about HyperSyn, ptex2d, ptex3d, hypermesh, dataflow DSL, FXV2 codegen from dataflow, subprocess graph validation, or the hypergraph composition layer.
Operate THIS machine as an obtnet fleet node — launching the node daemon correctly, what the controller may do to this machine (jobs, builds into the staging, checkout gitsync/sync), node-side etiquette and troubleshooting. Use when setting up, running, or debugging the node side of the fleet (the controller-side skill is `obtnet`).
Drive the obtnet fleet (distributed build/run/sync across machines) via obt.net.py — node routing, async jobs, artifact fetch, git-free tree sync. Use whenever work should run on another machine or files must move between machines without git.
Answer questions about orkid's OBT build system, ork.build.py, CMake structure, module layout, ork.python environment, staging directories, pyext builds, and environment variables. Use when the user asks about building, compiling, CMake, or project structure.
Answer questions about orkid's ComputeInterface (CI), compute shader dispatch, indirect dispatch, SSBO binding for compute, memory barriers, image/sampler binding, dispatch phases. Use when the user asks about compute shaders, GPU compute, or dispatch.

PipeWire stream callback model:
PipeWire Main Loop Thread (on_pw_process)
├─ Dequeue SPA buffer from pw_stream
├─ synth->compute(num_frames, input_buffer)
├─ Interleave L/R floats → output buffer
├─ Compute CPU load percentage
└─ Re-queue buffer
