What problem does it solve? Writing deep, line-by-line technical documentation for a completed User Story before opening a PR is tedious and often skipped. This Skill automates the creation of a structured EXPLAINED.md file in docs/Epics/ by reading the branch's git diff and following the project's established documentation pattern. ## Core Features & Use Cases - Diff-Driven Documentation: Reads the current branch name, git diff, and commit history to explain only the code that was added or modified. - Strict Pattern Compliance: Enforces the project's Epics doc pattern including Obsidian frontmatter, Portuguese prose, field tables for Pydantic models, ASCII flow diagrams, and mandatory Related Notes wikilinks. - Vault Index Updates: Automatically adds the new doc entry to docs/README.md so the Obsidian vault index stays current. - Use Case: After finishing a feature branch like feature/US-042-docker-client, ask the assistant to document the US before the PR, and it produces docs/Epics/Docker Sandbox/US-042-DOCKER-CLIENT-EXPLAINED.md with full code explanations. ## Quick Start Ask the assistant to document the current branch's User Story and generate the EXPLAINED.md file before opening the pull request.
