bcpqc-add-signature-algorithm

Port a post-quantum signature algorithm into the BCPQC provider, end to end — lightweight engine plus JCA/JCE wiring, OID converter plumbing, BC↔BCPQC bridge, module-info, tests, and release notes. Use this skill whenever the user wants to add a new PQC signature scheme (FAEST, SNOVA, MAYO, HAWK, etc.) to BCPQC, port a reference C/Rust implementation into BC, or finish a half-wired PQC algorithm whose certs/keys can't be decoded through the standard BC provider. Reach for this skill even when the user only mentions the algorithm name and the verb is "add", "port", "wire up", or "integrate" — the file set and the BC-vs-BCPQC split that this skill captures are non-obvious and easy to half-finish.

build-jdk13-docker

Build and test the legacy jdk1.3 (build1-3) distribution on a modern host by running the genuine Sun JDK 1.3.1 inside an i386 / glibc-2.3.6 Docker container. Use this whenever the user wants to run "build1-3" / the "jdk1.3" or "Java 1.3" build, get a bcprov-jdk13 jar, reproduce a genuine-1.3 compile failure, or when a genuine JDK 1.3.1 won't start on the host ("can't find libjava.so", missing libstdc++-libc6.1-1.so.2, or a green-threads Classic VM segfault). Captures the container recipe, why glibc < 2.4 is mandatory, the uname/libstdc++/threads traps, and that the jdk1.3 source overlays have rotted (the real source floor is Java 1.4).

ifcopenshell-docker-build

Build a real ifcopenshell_wrapper (.so + .py) and IfcConvert locally via the docker/ifcos_env toolchain, then wire them into a checkout for running C++-dependent parts of the test suite (geometry, the SWIG wrapper stub, the C++ parser). Use whenever a task needs to compile IfcOpenShell's C++ core rather than just read/patch source - e.g. reproducing or fixing a bug in src/ifcgeom, src/ifcparse, src/ifcwrap, or validating util/scripts/validate_stub.py against the actual generated wrapper.

pg-durable-sql

Generate correct pg_durable SQL code for durable function workflows. USE WHEN: writing pg_durable DSL, creating durable functions, using df.start(), composing ~> |=> & | ?> !> @> operators, building ETL pipelines, loops, parallel joins, race conditions, conditional branching, HTTP requests, signals, cron scheduling, or variable substitution in pg_durable. DO NOT USE FOR: general PostgreSQL queries unrelated to pg_durable, Rust extension development, or duroxide internals.

ingesting-spec

Guide for ingesting the latest OpenAI TypeSpec specification into the openai-dotnet SDK. Use this when asked to update or ingest OpenAI API specs, copy base TypeSpec files from upstream, fix client TSP compile errors, or run code generation for new API areas.

nunit-api-design

Use when adding or modifying public API surface in NUnit — new or changed constraints, attributes, assertions, helpers, or any type/member visibility change. Covers the conventions NUnit maintainers enforce for types that ship to consumers of the framework.

nunit-code-style

Use when writing or modifying C# method bodies, type declarations, or non-trivial logic in NUnit source. Covers NUnit's taste-and-judgment conventions — exception construction, simplification, naming intent, `StringComparison`, non-null check form, and `var` usage — that aren't already caught at build time.

nunit-threading-and-async

Use when writing or modifying async code in NUnit — async test lifecycle (setup/teardown), `TestExecutionContext`, `AsyncLocal`, `Task`/`ValueTask` continuations, blocking vs non-blocking waits, or conditional `Thread.Abort` code. Covers the threading/async conventions the NUnit runtime depends on.
