workflows
Use for PR review remediation or versioned work package creation/execution. Each workflow has a step-by-step procedure; read it and follow it exactly.
zig
Performance-first Zig guidance for systems code. Use for Zig speed, allocation, benchmark, batch API, module-readiness, hot-loop, compiler-output, and machine-level performance work. Read the machine-level and benchmarking references first, use compiler/allocation references when the evidence gap needs them, and match the response to the user's request: design discussion, implementation, review, or evidence report.
