# Changelog Patterns

Changelog Patterns analyzes ADVPL/TLPP diffs or changed-file lists to generate structured changelogs and delivery notes. It classifies changes, estimates business impact, and detects affected database tables for TOTVS Protheus work.

**Install:**

```bash
npx degit https://github.com/thalysjuvenal/advpl-specialist/tree/main/skills/changelog-patterns ~/.claude/skills/changelog-patterns
```

## README

# Changelog Patterns

This skill defines how to analyze ADVPL/TLPP code changes (via git diff or a supplied file list) and produce a structured changelog: change type classification (NEW/FIX/CHANGE/REMOVE/REFACTOR with Portuguese labels), impact level assessment (ALTO/MEDIO/BAIXO), detection of affected database tables from `DBSelectArea`/`RecLock`/`BeginSQL` patterns, and output in either Markdown or plain-text format.

Activate this skill when the user wants a client-facing or internal changelog, release notes, or delivery documentation generated from a set of code changes. It does not cover generating documentation headers or technical routine specs from a single source file with no diff context -- that is closer to a documentation-generation task and out of scope for this skill's diff-analysis process; it also does not cover code review findings (see `advpl-code-review`) or the migration checklist for `.prw` to `.tlpp` conversions (see `advpl-to-tlpp-migration`).
