An AI skill is a structured system prompt or set of custom instructions that gives AI assistants like ChatGPT, Claude, and Gemini specialized capabilities. It includes a clear role definition, specific knowledge areas, step-by-step processes, and quality criteria that help AI perform specific professional tasks.

How does Skill This work?

Simply describe your professional expertise in plain text. Our free AI skill generator analyzes your input and transforms it into a structured system prompt. The skill is then graded on clarity, specificity, and usefulness. You can share your skill via a unique URL or copy it to use as custom instructions with any AI assistant like ChatGPT, Claude, or Gemini.

Is Skill This free to use?

Yes, Skill This is completely free. No account or payment is required. You can create unlimited skills and share them with anyone.

How is my skill graded?

Skills are graded on a scale from A+ to F (0-100 points). The grade reflects how clear, specific, and actionable your skill is. Higher grades indicate skills that AI assistants can use more effectively.

How do I use my skill with an AI assistant?

Copy your generated skill and paste it into the system prompt or custom instructions of any AI assistant. For ChatGPT, use Personalization > Custom Instructions. For Claude, add it to a Project's instructions. For Cursor or other IDEs, save it as a .cursorrules or CLAUDE.md file. The AI will then adopt that skill and perform tasks according to your expertise.

Configuring Weaving Projects in TempoWeave - AI Skill Graded A- | Skill This

name: configuring-weaving-projects-in-tempoweave
description: Guides setup and planning of weaving projects in TempoWeave's Project Information dialog, covering loom setup, yarn/warp calculations, color breakdowns, heddle counts, and project documentation. Use when a user is setting up a new weaving draft, calculating yarn or warp requirements, troubleshooting sett/EPI/PPI values, planning target finished dimensions, or preparing a Weaver's Writeup in TempoWeave.

Quick Start14 / 15

To set up a new project from scratch, open Project tab > Project Info and work through tabs in this order:

Setup — set Shafts, Treadles, Sett (EPI), Beat (PPI), and reed/raddle info
Planning — enter Planned Warp Length, Calculation Drivers, click Calculate Yarn
Project Notes — add Title, Author, Tags
Heddle Count — verify each shaft has enough heddles before threading
Color Information — confirm yardage per color (requires Planning tab calculated first)
Cloth Construction — only relevant after using Double Cloth feature
Weaver's Writeup — click Generate Template, fill in, export

Recommendation▾

Add a brief note on what TempoWeave is (assumed context) for users unfamiliar with the tool, or confirm it's always used in-context with the app open

Workflow14 / 15

Progress:

Key calculation chains:

Width in Reed = Warp Ends ÷ Sett (EPI)
Woven Length = Weft Picks ÷ Beat (PPI)
Finished Width = Width in Reed − Draw-in, then reduced by Shrinkage Width %
Finished Length = Woven Length reduced by Shrinkage Length %
Min Warp Length = (Woven Length × (1 + Warp Take-Up%) × Pieces) + Fringe + Sampling + Loom Waste
Target-size (backward) flow: Finished Width/Length → Req Width in Reed → Required Warp Ends (× Sett) → Required Weft Picks (× Beat)

Recommendation▾

Include a 'bad output' example (e.g., miscalculated warp length from skipping shrinkage %) to show contrast with correct results

Examples18 / 20

Example 1: Forward calculation (draft exists, need yarn amount) Input: Draft has 240 warp ends, sett at 20 EPI, 480 weft picks, beat at 18 PPI. Planning for 1 piece, no fringe, no sampling, loom waste 24", warp take-up 8%, weft take-up 8%. Output:

Width in Reed = 240 ÷ 20 = 12"
Woven Length = 480 ÷ 18 = 26.7"
Min Warp Length ≈ 26.7" × 1.08 + 24" ≈ 52.8" → round up and enter Planned Warp Length (e.g., 54")
Click Calculate Yarn → warp/weft yardage populate from Planned Warp Length, sett, and take-up

Example 2: Backward calculation (target finished size known) Input: Want a finished scarf 8" wide × 60" long after 10% width shrinkage and 1" draw-in, sett 20 EPI, beat 18 PPI. Output:

Req Width in Reed = (8" ÷ 0.90) + 1" ≈ 9.9"
Required Warp Ends = 9.9 × 20 ≈ 198 ends
Woven Length per Piece = 60" ÷ (1 − length shrinkage %)
Required Weft Picks = Woven Length per Piece × 18

Example 3: Color yardage troubleshooting Input: Color Information tab shows dashes in Warp Yds/Weft Yds/Total Yds columns. Output: Go to Planning tab, enter Planned Warp Length (and Override Width/Length if needed), click Calculate Yarn, return to Color Information — yardage now populates proportionally by thread count percentage.

Recommendation▾

Consider adding a troubleshooting table for error states beyond the Color Information dash issue, e.g., invalid heddle counts or clamped treadling

Best Practices

Always set Sett and Beat before doing any Planning tab work — everything downstream depends on them.
Use Override Width / Override Woven Length on the Planning tab when the actual plan differs from what's literally in the draft (e.g., weaving many more repeats than shown).
Enter take-up and shrinkage percentages based on the specific structure (waffle weave needs much higher take-up than plain weave) rather than leaving defaults.
Check Heddle Count before threading, not after — catching an uneven/insufficient heddle distribution early saves rework.
Add Tags consistently (use autocomplete suggestions) so projects are searchable later by fiber, structure, or purpose.
When planning multiple pieces from one warp, use the Pieces field rather than manually multiplying woven length yourself — it keeps Total Woven and yarn calculations consistent.
For double cloth, only set Cloth Construction tab values after running the Double Cloth conversion — this tab documents, it doesn't create, the structure.

Common Pitfalls

Forgetting to click Calculate Yarn after changing Planning tab values — the yardage fields won't auto-update to reflect new drivers.
Confusing Reed vs. Raddle sections — Reed determines actual EPI/sett; Raddle is just for spreading warp evenly during beaming and has wider spacing.
Leaving Draw-In and Shrinkage at 0 — this makes "Finished" dimensions equal to loom dimensions, which is rarely accurate.
Setting Multi-Treadle off when a draft actually needs double-treadle presses — treadling combinations will be clamped/invalid.
Reducing Shaft or Treadle count without checking existing threading/treadling — references above the new max get reassigned or clamped, potentially altering the draft unintentionally.
Not entering Planned Warp Length before checking Color Information — yardage columns will just show dashes with no indication of why until you look for the warning message.
