Python Code Health Check with pyscn

Run the pyscn CLI to give a quick, quantified picture of code quality. No install needed:

uvx pyscn@latest analyze <path>

The summary output includes a health score (0-100), a letter grade (A-F), and per-category metrics.

Commands

For machine-readable detail add --json. Report files are NOT written to stdout. They go to .pyscn/reports/ under the current working directory and the path is printed on completion; read that file.

Interpreting Results

• Score 0-100 with letter grade; category breakdowns cover complexity, dead code, duplication, coupling (CBO), cohesion (LCOM), dependencies, and architecture.
• Lead with the grade and the weakest categories, then name the top offenders (files/functions) driving them.
• For deeper follow-up, hand off to the focused skills: refactoring targets → refactoring, module structure → architecture-review.

Always explain the score in plain terms and suggest the highest-impact next step.

MCP Alternative

If the pyscn-mcp MCP server is connected, you can use its tools instead of the CLI: get_health_score (score + grade) or analyze_code (output_mode: "summary" gives the health score plus high-level metrics per category). Results are returned inline with no report files.
