This skill should be used when the user mentions "build system", "Makefile", "Bazel", "Gradle", "Maven", "Nx", "Turborepo", "monorepo", "build targets", "how to build", "which command", "build one package", or "affected/changed projects". It provides a methodology for reading and driving common build systems and monorepos, listing targets, reading the dependency graph, and building or testing a single package without building the world.
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
# Build System Decode ## Purpose A repeatable way to understand and drive an unfamiliar build, so you can answer "what can I run, what does it do, and how do I build/test just my package?" without holding the whole dependency graph in your head. Detect the tool from its manifest, use the tool's own introspection instead of hand-parsing config, and always find the narrowest command that gets your package green. ## Detection: manifest → build system | Manifest file(s) | Build system | Introspection command | |------------------|--------------|-----------------------| | `Makefile` | Make | `make help`, `make -qp`, grep `.PHONY` | | `BUILD(.bazel)`, `WORKSPACE`, `MODULE.bazel` | Bazel | `bazel query //...` | | `build.gradle(.kts)`, `settings.gradle` | Gradle | `./gradlew tasks --all` | | `pom.xml` | Maven | `mvn help:describe`, `<modules>` | | `package.json` `scripts` + lockfile | npm/pnpm/yarn | read `scripts`, `<pm> run` | | `nx.json`, `project.json` | Nx | `nx graph`, `nx show projects` | | `turbo.json` | Turborepo | `turbo run build --dry` | | `CMakeLists.txt` | CMake | `cmake --build . --target help` | | `Cargo.toml` (`[workspace]`) | cargo | `cargo metadata`, `--workspace` | …

How to install
mdr add sigistry/marketplace/build-system-decode@sha256:2a818d8f623f4ec3The line at the top of this page pins the label git:20260826.571bc2f, 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.
