Claude Code plugin for codopsy-ts

Analyze code quality, track quality trends, and auto-fix issues — right from Claude Code.

What it does

This plugin adds the /codopsy skill to Claude Code. It runs codopsy-ts on your codebase, interprets the results, and can automatically fix the issues it finds.

Quality Score — A–F grade per file and project (0–100 scale)

Analyze — cyclomatic & cognitive complexity, 13 lint rules, per-file breakdown

Baseline — save a quality snapshot, fail CI if quality degrades

Hotspots — find high-risk files by combining complexity with git churn

Fix — Claude reads the analysis, understands each issue, and applies minimal fixes

---

Install

/plugin marketplace add O6lvl4/codopsy-ts-skill
/plugin install codopsy-ts

Requires codopsy-ts v1.1.0+ (npm install -g codopsy-ts)

---

Usage

# Analyze ./src (default)
/codopsy

# Analyze a specific directory
/codopsy ./lib

# Analyze and auto-fix all issues
/codopsy --fix

# Analyze a specific directory and fix
/codopsy ./lib --fix

# Save baseline and compare
/codopsy --baseline

# Include hotspot analysis (complexity × git churn)
/codopsy --hotspots

What happens

Report mode (default)

1. Runs codopsy-ts analyze with --verbose
2. Shows Quality Score (A–F grade) and grade distribution
3. Presents a summary: file count, error/warning/info counts, hotspots
4. Lists each issue with file, line, rule, and message

Baseline mode (--baseline)

1. Saves current quality metrics as a baseline snapshot
2. On subsequent runs, compares against baseline
3. Reports score change, issue delta, and improved/degraded files

Hotspot mode (--hotspots)

1. Runs analysis with --hotspots flag
2. Combines complexity scores with git churn (commits, authors)
3. Reports risk levels: HIGH, MEDIUM, LOW

Fix mode (--fix)

1. Runs analysis
2. Fixes issues in priority order:
   • no-var → replace with let/const
   • eqeqeq → replace == with ===
   • prefer-const → change let to const
   • no-empty-function → add implementation or explanatory comment
   • no-param-reassign → introduce local variable
   • max-params → extract options object
   • max-depth → extract helpers, early returns
   • max-complexity / max-cognitive-complexity → break down functions
   • max-lines → extract into modules
   • no-nested-ternary → replace with if/else (JSX boundaries excluded)
   • no-any → add type annotations
3. Re-runs analysis to verify improvements
4. Reports before/after comparison with quality score change

Example

> /codopsy

=== Codopsy Analysis ===

Quality Score: A (95/100)
Files: 12 | Errors: 0 | Warnings: 3 | Info: 5
Grade distribution: A: 9, B: 2, C: 1

| File             | Line | Rule           | Score | Message                                    |
|------------------|------|----------------|-------|--------------------------------------------|
| src/parser.ts    | 42   | max-complexity | B (78)| Function "parse" has complexity 14 (max 10) |
| src/utils.ts     | 8    | no-var         | A (92)| Unexpected var, use let or const            |
| src/handler.ts   | 15   | eqeqeq         | A (90)| Expected "===" but found "=="              |

> /codopsy --fix

Fixed 3 issues:
  ✓ src/utils.ts:8 — var → const
  ✓ src/handler.ts:15 — == → ===
  ✓ src/parser.ts:42 — extracted helper functions

Re-analysis: A (99/100), 0 errors, 0 warnings, 5 info
