English Formatting Check

Purpose

Verify English documentation against every rule in writing-guides/formatting-guide.md. Mechanical rules are enforced by a linter script (check-format-en.py); judgment-call rules are checked by reading the file.

Before Starting

Audit the entire file, not just the diff. Default to files currently under review, detected via:

• git diff --name-only (unstaged changes in tracked files)
• git diff --cached --name-only (staged changes)
• Untracked files from git status --porcelain (lines starting with ??)

Filter for .mdx and .md files under en/. If no files are detected, ask the user which files to check.

Checks

Part 1 — Deterministic (run the linter)
