grammar-check

The grammar-check skill acts as an expert copyeditor and writing consultant designed to enhance the quality of professional documentation, marketing copy, and internal communications. It goes beyond simple spell-checking by conducting a holistic analysis of text to ensure that the writing is logically sound, grammatically correct, and stylistically consistent. The skill is specifically tailored for product managers, content creators, and team leads who need to maintain high standards of clarity and readability in their written outputs without delegating the entire drafting process to an AI. By focusing on targeted, surgical interventions rather than full-scale rewrites, the agent empowers users to maintain their unique voice while polishing the final result.

• Performs a multi-layered scan for grammar errors including spelling, punctuation, subject-verb agreement, tense consistency, and modifier placement.

• Evaluates logical structure by identifying contradictions, unsupported claims, vague assertions, and incomplete reasoning.

• Analyzes flow to detect issues such as choppy transitions, overuse of passive voice, redundant phrasing, and ambiguous pronoun references.

• Provides a structured output format including error location, clear identification of the issue, specific suggestions for correction, and a rationale for every change.

• Prioritizes issues into categories: Critical (grammar/logic errors that confuse readers), Important (flow and readability), and Minor (stylistic polish).

• Users should provide a clear objective for the text, such as 'persuading stakeholders' or 'onboarding new users,' to ensure the tone and recommendations are contextually appropriate.

• The tool is best used on draft content after the primary ideas have been established but before final publication or delivery.

• The output is strictly formatted to avoid unnecessary full-text rewrites, keeping the user in control of the final narrative.

• Constraints include keeping suggestions focused; the agent is not intended to rewrite entire long-form documents from scratch, but rather to provide a line-by-line or paragraph-level review of existing content.

• It supports various writing styles from technical documentation and PRDs to casual internal emails and high-stakes social media posts.
