noir-circuit-patterns from sparq-org/sparq is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Patterns and gotchas for writing Noir circuits that implement SPARQL primitives over committed RDF graphs. Use when implementing BGP matchers, joins, filters, projections, or hashing-to-field strategies; when sizing constraint budgets; when laying out public inputs that bind to a commitment scheme; or when interfacing nargo / Barretenberg (bb) tooling. Always confirm syntax against the noir-lang context7 docs (/noir-lang/noir) before writing code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Noir circuit patterns for ZKP-SPARQL Reusable patterns for the Noir circuits that prove correct SPARQL evaluation over committed RDF graphs. These are starting points; verify any specific syntax via the `/noir-lang/noir` context7 docs before pasting into code. For generic Noir guidance the upstream skills cover better: `noir-developer` for circuit structure / stdlib / workspace setup, `noir-idioms` for the idiomatic ACIR-vs-Brillig style, `noir-testing` for the testing framework. This skill is intentionally narrow to: SPARQL-domain patterns (BGP, joins, filters, triple commitments), plus the Noir-language gotchas this codebase has hit specifically (orphan rule, `pub(crate)` for verifier-hint soundness, trait associated constants in const-generic positions, IEEE-754 `total_compare` vs `Ord`, witness-vs-comptime branches). For cost analysis on a candidate gadget see the sister skill `noir-optimisation`. ## Always-do - **Pin the toolchain.** `Nargo.toml` declares `compiler_version`. README of the circuit dir documents the matching `bb` version. - **Query context7 first.** Before guessing a stdlib function name, a trait bound, or a generic syntax, run …

How to install
mdr add sparq-org/sparq/noir-circuit-patterns@sha256:e0d231119a23620aThe line at the top of this page pins the label git:20260612.13b231c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
