SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve? Drafts often contain grammar mistakes, unsupported claims, and awkward phrasing that undermine clarity, but full rewrites erase the author's voice. This Skill reviews text against its stated purpose and audience, then delivers specific, prioritized correction suggestions without rewriting the document. ## Core Features & Use Cases - Three-Category Error Detection: Scans for grammar errors (spelling, punctuation, subject-verb agreement, tense consistency), logic errors (unsupported claims, contradictions, vague statements), and fluency errors (weak transitions, passive voice overuse, redundancy, unclear pronoun references). - Prioritized, Actionable Feedback: Each issue includes its location, the problem, a concrete fix, and the reasoning, ranked by severity so the highest-impact changes come first. - Tone-to-Goal Alignment Check: Evaluates whether the text's tone matches its stated objective and target audience. - Use Case: Before sending an investor update email, provide the text and the objective "persuade investors to join our Series A" to receive a categorized list of grammar, logic, and fluency fixes plus the top priority revisions. ## Quick Start Review this draft for grammar, logic, and fluency issues given the objective "explain our product features to new users", and list prioritized correction suggestions without rewriting the text.

FAQPage Schema
How do I check a draft for grammar and logic errors without rewriting it?

Provide the text along with its intended purpose and audience. The review scans for grammar, logic, and fluency issues, then returns location-specific fixes with reasoning while preserving the author's original voice.

What types of writing errors does a grammar and fluency review catch?

It catches spelling, punctuation, subject-verb agreement, and tense consistency problems, plus logic issues like unsupported claims and contradictions, and fluency issues like weak transitions, passive voice overuse, and unclear pronoun references.

Can grammar checking work for different audiences and tones?

Yes. The review first establishes context including document type, target readers, and expected tone, then evaluates whether the text's tone matches its objective and flags inconsistencies between formal and casual registers.

When should text be left unchanged during proofreading?

Intentional stylistic choices such as short punchy sentences, appropriate informal language, rhetorical devices, and personal voice should remain untouched. Corrections focus on clarity and correctness rather than enforcing uniform style.

Why does feedback include reasoning for each correction?

Explaining why a change matters helps writers learn underlying principles instead of just following rules. Each suggestion cites the clarity, grammar, or flow rationale so authors can apply the lesson to future writing.
