ALWAYS use this skill when writing or refactoring code. Includes context-dependent sub-skills to empower different coding styles across languages and runtimes.
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
# Coding Effectively ## Required Sub-Skills **ALWAYS REQUIRED:** - `howto-functional-vs-imperative` - Separate pure logic from side effects - `defense-in-depth` - Validate at every layer data passes through **CONDITIONAL:** Use these sub-skills when applicable: - `howto-code-in-typescript` - TypeScript code - `howto-code-in-rust` - Rust code - `howto-develop-with-postgres` - PostgreSQL database code - `programming-in-react` - React frontend code - `writing-good-tests` - Writing or reviewing tests - `property-based-testing` - Tests for serialization, validation, normalization, pure functions ## Property-Driven Design When designing features, think about properties upfront. This surfaces design gaps early. **Discovery questions:** | Question | Property Type | Example | |----------|---------------|---------| | Does it have an inverse operation? | Roundtrip | `decode(encode(x)) == x` | | Is applying it twice the same as once? | Idempotence | `f(f(x)) == f(x)` | | What quantities are preserved? | Invariants | Length, sum, count unchanged | | Is order of arguments irrelevant? | Commutativity | `f(a, b) == f(b, a)` | …

How to install
mdr add ed3dai/ed3d-plugins/coding-effectively@sha256:a0559c2931633e91The line at the top of this page pins the label git:20260429.47257b5, 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.
