Reviewed by Daniel Nikulshyn·Updated July 2026

Overview

Metrics (Grade A) is a security-tested development skill for Claude AI that calculates metrics for ADVPL/TLPP functions in Protheus Universo 4 Feature B, version 0.6.0 and later. It provides metrics such as cyclomatic complexity (McCabe), lines of code (LOC), nesting depth, fan-out, and number of parameters. The tool helps identify complex functions that may require refactoring and provides insights into code quality. It can be used to rank functions by complexity, detect large functions, and identify functions with high complexity and no documentation.

Use cases

Top-10 most complex functions

Use /plugadvpl:metrics --sort cc to identify the top-10 most complex functions in a project

Identifying large functions

Use /plugadvpl:metrics --min-loc 300 --sort loc to detect functions with over 300 lines of code

High complexity and no documentation

Use /plugadvpl:metrics --min-cc 15 to identify functions with high complexity and no documentation

Pros & Cons

Pros

Helps identify complex functions that may require refactoring
Provides insights into code quality
Supports ranking functions by complexity
Detects large functions and functions with high complexity and no documentation

Cons

May have limitations with macro substitution
Cyclomatic complexity may be slightly high or low if macro expands to extra blocks
Requires re-ingestion when schema changes (e.g., from v9 to v10)

Q&A

Are there any known limitations?

Macro substitution can affect accuracy of cyclomatic complexity, and the tool may need re‑ingestion after schema updates such as version changes.

Asked by Mireille Dupont · Jun 22, 2026

How can the tool help with code quality and refactoring?

By ranking functions by complexity, detecting large or highly nested functions, and flagging functions with no documentation, it highlights candidates that may need refactoring.

Asked by Lena Fischer · May 5, 2026

Which Protheus version does this skill support?

It works on Universo 4 Feature B, version 0.6.0 and later. If the schema changes (e.g., from v9 to v10), the tool must be re‑ingested.

Asked by Devin Walker · Mar 9, 2026

What metrics does Metrics (Grade A) calculate for ADVPL/TLPP functions?

It computes cyclomatic complexity (McCabe), lines of code (LOC), nesting depth, fan‑out, number of parameters, and checks for missing function documentation.
