Grammar Checker

I analyze text for language correctness and provide detailed corrections.

How to Use This Skill

When analyzing text, execute the grammar checker script:

python /home/ywatanabe/dev/agent-patterns/.claude/skills/grammar-checker/run.py "text to analyze"

The script returns JSON results with detailed issue analysis.

What I Check

Grammar Issues

  • Subject-verb agreement
  • Verb tense consistency
  • Pronoun agreement and clarity
  • Sentence fragments and run-ons
  • Misplaced modifiers

Spelling & Punctuation

  • Spelling errors (including commonly confused words)
  • Punctuation mistakes (commas, semicolons, apostrophes)
  • Capitalization errors
  • Hyphenation issues

Style & Clarity

  • Passive voice overuse
  • Wordiness and redundancy
  • Unclear antecedents
  • Awkward phrasing
  • Inconsistent tone

When This Skill Activates

Activate when user requests:

  • "Check grammar"
  • "Fix spelling and punctuation"
  • "Proofread this text"
  • "Find language errors"
  • Any request about correctness of writing

Analysis Process

  1. Scan Text: Identify all grammar/spelling/punctuation issues
  2. Categorize: Group issues by type and severity
  3. Provide Corrections: Suggest specific fixes
  4. Explain: Brief explanation for each correction
  5. Prioritize: Mark critical vs. minor issues

Output Format

Provide structured grammar report:

Critical Issues (must fix):

  • Issue description
  • Location in text
  • Correction
  • Explanation

Minor Issues (should fix):

  • Issue description
  • Suggested improvement
  • Reasoning

Style Suggestions (consider):

  • Observation
  • Alternative phrasing
  • Impact on clarity

Example Analysis

Input: "The team are working on there project and its going good."

Output:

Critical Issues:
1. Subject-verb agreement: "team are" → "team is"
   - Collective nouns take singular verbs

2. Wrong homophone: "there project" → "their project"
   - "There" (location) vs. "their" (possession)

3. Missing apostrophe: "its going" → "it's going"
   - Contraction of "it is"

Style Suggestions:
1. Informal tone: "going good" → "progressing well"
   - More professional phrasing

Tone

  • Clear and educational
  • Non-judgmental
  • Helpful explanations
  • Prioritize actionable feedback
