1Skill Creatorskill-creator is an Agent Skill from aiskillstore/marketplace for authoring, packaging, and iterating custom Agent Skills defined in SKILL.md format. The skill guides developers through structuring skill metadata, writing instructions agents can follow, and running eval loops to verify capabilities install and behave correctly across Claude Code, Cursor, and Codex. Developers reach for skill-creator when extending agent workflows with reusable domain expertise rather than one-off prompts. The marketplace repo ships under Apache License 2.0, aligning skill distribution with standard open-source licensing practices for agent tooling.899installs2Frontend Designfrontend-design is an agent skill from aiskillstore/marketplace for creating production-grade frontend interfaces with intentional aesthetics instead of generic templates. It walks through design intent, typography pairing, semantic color tokens often using oklch, motion rules that respect prefers-reduced-motion, asymmetric layout composition, fluid typography with clamp, and container-query responsive patterns. The guide warns against overused defaults such as Inter-only stacks and purple-on-white gradients, and emphasizes WCAG AA contrast targets of 4.5:1 for body text. Use frontend-design when you are building components or pages and need cohesive visual direction, not just functional markup, especially before handing UI to implementation agents.248installs3Xlsxxlsx is an aiskillstore/marketplace agent skill for spreadsheet-first tasks where the deliverable must be a workbook file, not a script or HTML report. The SKILL.md supports .xlsx, .xlsm, .csv, and .tsv inputs and outputs, mandating Excel formulas instead of hardcoded Python calculations so models stay recalculable. Developers reach for xlsx when cleaning messy tabular exports, building financial models with industry color conventions, or generating charts and formatted tables via pandas and openpyxl. A required scripts/recalc.py step recalculates formulas through LibreOffice, scans for #REF!, #DIV/0!, #VALUE!, and related errors, and returns JSON error summaries. The workflow distinguishes pandas for bulk analysis from openpyxl for formulas, formatting, and template preservation, with explicit rules for financial model typography, assumption placement, and zero-formula-error delivery.235installs4Pptxpptx is an agent skill for creating, editing, and analyzing Microsoft PowerPoint .pptx presentations from code and markup workflows.
