Refactor code to reduce cyclomatic complexity so it stays readable, maintainable, and aligned with the long-term vision of the codebase, not just optimized for AI comprehension. Use whenever the user asks to refactor, simplify, clean up, or review code quality; mentions complexity, maintainability, readability, spaghetti code, deeply nested logic, or god functions; or asks to check AI-generated code before merging. Also use proactively after writing any nontrivial function with heavy branching.
Source documentation, not instructions for this website. Review permissions before running any commands.
Purpose: AI-written code often works but branches like a jungle. This skill: measure complexity, refactor hotspots, keep code human-maintainable.
CC = decision points + 1. Decision points: if, else if, case, loops, catch, ternary, &&, || in conditions.
Project linter config wins. If eslintrc, radon config, sonar config, or similar sets a complexity threshold, use that. No config: use defaults below.
Thresholds:
Prefer real tools over eyeballing when environment allows:
radon cc -s -a <path>complexity rulegocyclolizard <path>No tool available: count manually, per function, show the count.
if (isEligibleForRefund(order)) beats a 4-clause boolean soup.End every refactor with:
## Complexity report
| Function | Before | After |
|----------|--------|-------|
| parseOrder | 14 | 4 |

Keep prose minimal. Numbers and diffs do the talking.

This skill: measure complexity, refactor hotspots, keep code human-maintainable. ## Measure first CC = decision points + 1. Decision points: `if`, `else if`, `case`, loops, `catch`, ternary, `&&`, `||` in conditions. Project linter config wins. If eslintrc, radon config, sonar config, or similar sets a complexity threshold, use that. No config: use defaults below. Thresholds: - 1-5: fine, leave alone - 6-10: watch, refactor if touching anyway - 11-15: refactor now - 15+: must split, no debate Prefer real tools over eyeballing when environment allows: - Python: `radon cc -s -a <path>` - JS/TS: eslint `complexity` rule - Go: `gocyclo` - Polyglot: `lizard <path>` No tool available: count manually, per function, show the count. ## Refactor tactics, in order of preference 1. **Guard clauses.** Invert conditions, return early, kill nesting. 2. **Extract function.** Each extracted piece gets a name that says what, not how. Names are documentation. 3. **Lookup table / map** instead of if-else or switch chains. 4. **Named predicates.** `if (isEligibleForRefund(order))` beats a 4-clause boolean soup. 5. **Polymorphism / strategy** for switch-on-type. Only when the switch appears in 2+ places. 6. **Flatten loops.** Extract loop body, use continue instead of nested if. ## Hard rules - Preserve behavior. Run tests before and after. No tests: say so, suggest adding, refactor conservatively. - Don't game the metric. A dense one-liner hiding 6 branches is worse than the honest if-chain it replaced. Complexity should move into well-named units, not disappear into cleverness. - Don't break public APIs or exported signatures without asking. - Small functions with clear names > few functions with comments explaining sections. - One responsibility per function. If the name needs "and", split. ## Workflow 1. Measure all touched functions, rank by CC descending. 2. Report hotspots with numbers before touching anything. 3. Refactor worst first, one function at a time. 4. Re-measure. Show before/after table: function, CC before, CC after. 5. Verify: tests pass, behavior unchanged, diff reviewable. ## Output format End every refactor with: ``` ## Complexity report | Function | Before | After | |----------|--------|-------| | parseOrder | 14 | 4 | Extracted: validateHeader, resolveDiscount Behavior verified: <how> ``` Keep prose minimal. Numbers and diffs do the talking.
