# Code Reviewer

Automated code review tooling that analyzes pull requests for complexity and risk, scans source for code smells and SOLID violations, and consolidates findings into structured review reports with a verdict, score, and prioritized action items. Supports TypeScript, JavaScript, Python, Go, Swift, and Kotlin.

## Core Capabilities

- **PR risk analysis** — scan git diffs for hardcoded secrets, SQL injection, debug statements, lint bypasses, `any` types, and TODO/FIXME, with a 1-10 complexity score.
- **Code quality checking** — detect long functions, large files, god classes, deep nesting, too many params, high cyclomatic complexity, missing error handling, unused imports, and magic numbers against fixed thresholds.
- **SOLID & antipattern detection** — flag structural, logic, security, performance, testing, and async antipatterns with fixes.
- **Review reports** — merge PR and quality findings into a verdict (approve / request changes / block), 0-100 score, and ranked action items in text, markdown, or JSON.
- **Review order prioritization** — sort files so security-sensitive code is inspected first.
- **Commit hygiene** — validate conventional-commit format across a branch.

## When to Use

- Reviewing a PR and needing fast pre-screening before manual logic review.
- Analyzing code quality or auditing a codebase for smells and SOLID violations.
- Generating a structured review report or review checklist.
- Gating merges in CI/CD on a quality score or review verdict.

## Clarify First

Before producing the review, confirm these inputs. If any is unknown or vague, ASK — do not assume:

- [ ] **What to review** — the git diff/branch (base and head) or a source directory (sets `--base`/`--head` or the path the analyzers scan)
- [ ] **Language** — TypeScript, JavaScript, Python, Go, Swift, or Kotlin (selects the rules `code_quality_checker.py` applies via `--language`)
- [ ] **Output & gate** — report format (text/markdown/JSON) and any pass/fail score threshold (sets the artifact format and CI verdict)

Stop rule: ask only the 2-3 that most change the output. If the user says "just draft it," proceed and list your assumptions at the top of the artifact.

## Tools

| Tool | Purpose | Command |
|------|---------|---------|
| `pr_analyzer.py` | Assess PR complexity and risk from a git diff | `python scripts/pr_analyzer.py . --base main --head feature-branch --json` |
| `code_quality_checker.py` | Detect code smells and SOLID violations in source | `python scripts/code_quality_checker.py ./src --language typescript --json` |
| `review_report_generator.py` | Combine PR + quality findings into a review report | `python scripts/review_report_generator.py . --format markdown --output review.md` |
