Enforce low Cognitive Complexity (SonarSource) and low Cyclomatic Complexity in ALL code written or modified, in any programming language, framework, or platform. This skill MUST activate automatically whenever code is being written, generated, modified, or refactored — no explicit trigger needed. Triggers include writing any function, method, class, module, script, handler, endpoint, test, or code block. Also triggers on "low complexity", "cognitive complexity", "cyclomatic complexity…
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
# Low Complexity Code Every function/method written or modified MUST target: - **Cognitive Complexity <= 5** (SonarSource metric). Acceptable up to 10 for inherently complex logic. Never exceed 15. - **Cyclomatic Complexity <= 5**. Acceptable up to 10. Never exceed 15. For full scoring rules, see [cognitive-complexity-spec.md](references/cognitive-complexity-spec.md). ## Cognitive Complexity Quick Reference **+1 for each:** `if`, ternary (`? :`), `switch` (whole), `for`, `while`, `do while`, `catch`, `else if`, `else`, `goto LABEL`, `break/continue LABEL`, each method in a recursion cycle, each sequence of like boolean operators (`&&` / `||`). **+1 nesting penalty** on top of structural increment for: `if`, ternary, `switch`, `for`, `while`, `catch` — when nested inside another flow-break structure. **Free (no increment):** method calls, `try`, `finally`, `case` labels, null-coalescing (`?.`, `??`), early `return`, simple `break`/`continue`, lambdas (but lambdas increase nesting level). ## Cyclomatic Complexity Quick Reference …

How to install
mdr add mryll/skills/low-complexity@sha256:816b45852df20c8fThe line at the top of this page pins the label v1.0.1, 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.
