Find grammar problems, unclear reasoning and awkward transitions in a draft, with each suggestion tied to a location and a reason. Useful for proofreading emails, articles or proposals while keeping the author's voice.

How to use it
Beginner. Paste the draft and describe its audience, purpose, language and tone. Request a prioritized list of issues with locations, suggested fixes and reasons, rather than a full rewrite. Check each suggestion against your intended meaning. Source examples use English grammar conventions; results for other languages need your own review.
The instructions themselves are not copied here. They stay in the author’s repository at the version below, so open them there and follow the author’s own steps.
This is what the instructions ask for, not something LuluSkill does. In a chat window nothing runs; in an AI tool that can work with your files, what actually happens depends on that tool and its permission settings.
Source, licence and checks

Pinned versionThis page describes commit c68487d721e4 of pm-toolkit/skills/grammar-check/SKILL.md. A newer version in the author’s repository is not covered until it is reviewed again.
Automated scanPassed (lowest risk), on Oct 13, 2026: 2 files checked, 0 findings. The scan looks for patterns such as shell commands, web requests, credential access and instruction overrides. It does not run the Skill and is not a full security audit.
ReviewRecorded on Oct 13, 2026 by LuluSkill’s AI project supervisor on the owner’s behalf. It checked the source, the licence file, the scan result and this description. It is not a human review and not a legal opinion.
