unclecatvn Skill

Create beautiful, professional HTML or React slide decks ready for fullscreen presentation. Use this skill when the user wants to: create a PPT/slide/presentation from an idea or outline; build a visually stunning slide deck from existing content; generate an HTML presentation that can be projected fullscreen; convert a document into a presentation. Trigger when you hear: 'create slides', 'make a PPT', 'presentation', 'slide deck', 'pitch deck', 'vibe ppt', 'make a talk', or any request to create a presentation.

For simple utilities enter at Level 4 (Contracts), for single-component tasks at Level 2 — see Complexity Calibration. Do not use for quick bug patches.

usekaneo Bundle

Build an animation from scratch, making the decisions in the order that determines whether it feels right — should it animate at all, what purpose, which tool, which properties, which curve and duration, how it interrupts, how it exits. Writes the implementation. Use when asked to animate something, add motion, make a component feel alive, or build a transition. For critiquing existing motion use review-animations; for auditing a whole codebase use improve-animations.

vueuse Bundle

Apply VueUse composables where appropriate to build concise, maintainable Vue.js / Nuxt features.

ar9av Skill

Scan the Obsidian wiki for page-level identity collisions — different pages covering the same concept under different names (e.g. "RSC" vs "React Server Components") — and merge them. Use this skill when the user says "dedup my wiki", "find duplicate pages", "merge duplicates", "identity resolution", "consolidate my wiki", "I have duplicate pages", or "my wiki has two pages for the same thing". Distinct from wiki-lint (which checks structure) and cross-linker (which adds links) — this skill makes destructive page-level merges and requires careful confirmation.

diegosouzapw Skill

External agent skill (MIT, github.com/DietrichGebert/ponytail). Forces the laziest solution that actually works: question whether the task needs to exist at all (YAGNI), reuse what is already in the codebase, reach for the standard library before custom code, native platform features before dependencies, one line before fifty. Climb the ladder on every coding task — writing, adding, refactoring, fixing, reviewing, or designing code, and choosing libraries or dependencies. Supports intensity levels: lite, full (default), ultra. Never cut validation, error handling, security, or accessibility.
