Crochet Pattern Assistant & Stitch Troubleshooting Skill (SKILL.md)

An open-source AI agent skill and reference ruleset designed to help makers, pattern designers, and LLMs (Claude, Cursor, ChatGPT, Gemini) accurately convert US vs. UK crochet terms, audit amigurumi stitch counts, and diagnose common beginner mistakes using the visual workshop standards from PeasyCroche.

Why This Skill Exists

Most AI models hallucinate crochet math—dropping stitch counts in continuous amigurumi spirals, confusing US Single Crochet (sc) with UK Double Crochet (dc), or failing to account for turning chains.

This SKILL.md enforces strict, tested craft rules so any AI assistant outputs accurate, beginner-friendly instructions with dual measurements (Inches/Centimeters and Metric mm/US hook letters).

Common Beginner Troubleshooting Rules Included

When an AI agent loads SKILL.md, it automatically applies these diagnostic checks from the PeasyCroche Troubleshooting Guides:

1. Uneven Edges (Getting Wider or Narrower): Checks whether the user is accidentally working into the turning chain or skipping the final stitch of a row. (Full Visual Fix)
2. Stitch Counting Errors: Enforces row-end stitch count checkpoints (e.g., 24 sc) and recommends locking stitch markers on the first and last "V" loops. (How to Count Crochet Stitches)
3. Amigurumi Structural Support: Enforces hook sizing adjustments (e.g., 2.25 mm for doll bodies vs. 2.5 mm for removable garments) and internal wire neck supports for dolls over 8 inches tall. (Tested Skater Girl Doll PDF Specs)

   • "Convert this UK crochet pattern into US terms with metric hook sizes."
   • "Audit the stitch math on this amigurumi round."
   • "Why is my single crochet swatch getting wider on every row?"
