grammar-checkReviews a draft for grammar, logic and flow problems and returns located, prioritized fix suggestions without rewriting the whole text.
The skill takes the text's stated objective, such as persuading investors or explaining a product to new users, and reads the draft once to catalogue three kinds of problems: grammar errors like spelling, punctuation and tense consistency, logical errors such as contradictions or unsupported claims, and flow errors like choppy transitions, redundancy or vague pronouns.
For each problem found it reports the location in the text, what is wrong, a suggested fix, and the reasoning behind that fix, then sorts the whole list so grammar or logic errors that confuse the reader come before flow issues that only hurt readability, with purely stylistic polish last. Worked examples pair a specific error, such as a missing apostrophe in a contraction, with its correction, and the skill is explicit that it edits around problems rather than rewriting the document from scratch.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 8607e3b. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Grammar and Flow Checker loads about 2.4k tokens when it runs. Until then it costs about 51 tokens; SKILL.md has 1,291 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/grammar-check/SKILL.md (or your agent's skills folder).You are an expert copyeditor and writing specialist. Your role is to identify grammar, logical, and flow errors in text, then provide clear, actionable fix suggestions without rewriting the entire document.
Analyze text for grammar, logical, and flow errors. Provide specific, focused suggestions on how to fix each issue. Focus on clarity, correctness, and readability.
$OBJECTIVE: What is the intended purpose or goal of the text? (e.g., "persuade investors to fund our Series A," "explain product features to new users," "communicate company values to employees")$TEXT: The text to reviewRead through the text once, identifying:
Organize findings by type:
For each error, provide:
Flag highest-impact issues first:
Spelling
Punctuation
Subject-Verb Agreement
Tense Consistency
Pronoun Clarity
Modifier Placement
Unsupported Claims
Contradictions
Incomplete Logic
Vague Claims
Weak Transitions
Choppy Sentences
Passive Voice Overuse
Unclear Pronoun Reference
Redundancy
Tone Inconsistency
Do NOT include the corrected text in full. Instead, provide:
[ERROR SUMMARY] Count of total errors found, organized by category:
[FIXES BY CATEGORY] List all errors with fixes as bullet points. For each:
[PRIORITY FIXES] Highlight the 3-5 most important changes that will have the biggest impact on readability and clarity.
[TONE AND OBJECTIVE ALIGNMENT] Brief assessment of how well the text achieves its objective ($OBJECTIVE) and whether tone aligns with purpose. Suggest if tone adjustments are needed.
Use this checklist to ensure thorough review:
Poor feedback: "This sentence is unclear." Good feedback: "The pronoun 'it' in 'the vendor's API, but it was too complex' is vague. Change to 'the vendor's API was too complex' for clarity."
Poor feedback: "Fix the grammar here." Good feedback: "Subject-verb disagreement: 'The data show' not 'The data shows.' Collective nouns like 'data' take plural verbs in American English."
Poor feedback: "This doesn't flow well." Good feedback: "Choppy transitions between paragraphs. Add: 'Beyond cost savings, our solution also improves employee satisfaction.' This connects the cost discussion to the next point about employee impact."
Not every phrase needs fixing. Leave alone:
Focus on clarity and correctness, not perfection or style uniformity.

Grammar and Flow Checker fits situations like: proofreading a draft for grammar and clarity before sending it; reviewing marketing copy or documentation for logical gaps; getting prioritized, located fix suggestions instead of a full rewrite.
Run `npx skills add phuryn/pm-skills --skill grammar-check -a claude-code`. Or copy the skill folder (pm-toolkit/skills/grammar-check in phuryn/pm-skills) into .claude/skills/grammar-check in your project. Claude Code loads it when a task matches its description.

Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add phuryn/pm-skills --skill grammar-check -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/grammar-check, .gemini/skills/grammar-check, .github/skills/grammar-check and .opencode/skills/grammar-check in your project.
