Code samples are never linted

Every fenced code block (```), indented code block, and inline `code span` is stripped before any rule runs — flagging "utilize" or "click on" inside a code sample would make this tool actively wrong, not just annoying. If a finding looks like it's inside code, that's a bug; the text above should show the highlight sitting outside any code formatting.

Why every finding cites a section

A linter that just says "wrong" asks you to trust it. This one links to the actual guide section it's applying, so you can check the reasoning yourself, or point a teammate at the source instead of just your opinion of it. Each rule was verified against the live guide before shipping — see the "Why this matters" expander on any finding.

This is a smaller rule set than a full linter like Vale — around a dozen of the highest-value checks, not the full 30-40 rule catalog either guide covers. It'll grow over time.

Terminology Consistency Checker

Find spelling variants, US/UK dialect mixing, and your own house-style violations, with counts for each.

Find technical terms, gendered defaults, ableist idioms, and loaded framing with a widely-adopted alternative — suggestions, not verdicts.

See your document's outline, plus skipped levels, duplicate headings, and wall-of-text sections, with a copyable table of contents.

Plain Language Checker

Find rare words, idioms, and phrasal verbs that may be hard for a non-native reader, with an allowlist for necessary jargon.
