noir-optimisation skillA

noir-optimisation is agent-read markdown (skill) from sparq-org/sparq: Cost model and optimisation reference for Noir circuits on the UltraHonk / Aztec Barretenberg stack. Use when sizing constraint budgets, deciding whether to push work into an `unconstrained` Brillig hint with an in-circuit verifier, comparing Field-arith vs typed `u64` bit operations, reading `bb gates` / `nargo info` / `noir-profiler gates` output, or weighing ACIR-opcode against backend-gate regressions. Companion to `noir-circuit-patterns` — that skill covers SPARQL-primitive shapes; this one.

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add sparq-org/sparq/noir-optimisation@git:20260612.13b231c
Exact content
mdr add sparq-org/sparq/noir-optimisation@sha256:7af23bb4d8496927

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
