Code Analyzer Skill

Installation

No separate download: the skill runs the in-repo tool .claude/tools/analysis/project-analyzer/analyzer.mjs.

• Ensure Node.js (v18+) is installed: nodejs.org or winget install OpenJS.NodeJS.LTS (Windows), brew install node (macOS).
• From the project root, the script is invoked automatically; no extra install steps.

Cheat Sheet & Best Practices

Metrics: Focus on cyclomatic complexity (decision paths), LOC, maintainability index, and duplicate blocks. Use ESLint complexity rule (e.g. "complexity": ["error", 15]) for JS/TS; optional chaining and default params add branches.

Process: Analyze before refactoring; run project-wide then drill into hotspots. Track trends over time (not one-off). Use max-depth, max-lines, max-nested-callbacks, max-params, max-statements alongside complexity.

Hacks: Start with project-analyzer output; filter by file type and threshold. Prioritize files with high complexity and high churn. Disable complexity rule only if you cannot set a sensible limit; prefer lowering the threshold over disabling.

Certifications & Training

No single cert; aligns with static analysis and ESLint complexity. ESLint: complexity rule, max-depth, max-lines, max-params. Skill data: Cyclomatic complexity, LOC, maintainability, duplicates; analyze before refactor; track hotspots and trends.

Hooks & Workflows

Suggested hooks: Pre-commit or CI: run project-analyzer/doctor for health; optional complexity gate. Use with developer (secondary), qa (secondary), code-reviewer (primary).

Workflows: Use with code-reviewer (primary), developer/ qa (secondary), c4-code (primary). Flow: run analyzer → filter hotspots → refactor or add tests. See code-review-workflow.md.

Memory Protocol (MANDATORY)

Before starting: Read .claude/context/memory/learnings.md

After completing:

• New pattern -> .claude/context/memory/learnings.md
• Issue found -> .claude/context/memory/issues.md
• Decision made -> .claude/context/memory/decisions.md

ASSUME INTERRUPTION: If it's not in memory, it didn't happen.
