motion-studio
by mercadoa1234-arcDANTE
v3 · The ultimate teaching-studio skill. Generate complete narrated educational, scientific, and engineering videos that combine: parametric CAD (build123d) with exploded views and orbital cameras (pyvista), Manim motion graphics and equation reveals, source-document image insertion (PDF page screenshots, Substack post screenshots, photographs, figures), composite overlays, AI-driven 3D reconstruction handoffs, and high-fidelity browser-GPU renders — all narrated with bundled neural Kokoro-82M CPU TTS (seven voices, no network). Audio-first pipeline: phrase-aware Kokoro chunking gives natural rhythm to short phrase rhythms ("never three, never six, never nine") and paragraph-level breath to long sections. Every shot picks its render engine (pyvista · manim · composite · image · bom · title) and the orchestrator dispatches. Output: soft-sub MP4 (mov_text track + sidecar SRT, no pixel burn-in) with -14 LUFS audio mastering, gentle denoise, optional subtle reverb. Trigger phrases: "make a teaching video", "explain X with animation and narration", "narrate this paper", "adapt this Substack post into a video", "3blue1brown style explainer", "CAD walkthrough with formulas", "design and animate a part with the math overlaid", "build a lesson from this source document".

xlsx
by TheWatcher01
"Use this skill any time a spreadsheet file is the primary input or output. This means any task where the user wants to: open, read, edit, or fix an existing .xlsx, .xlsm, .csv, or .tsv file (e.g., adding columns, computing formulas, formatting, charting, cleaning messy data); create a new spreadsheet from scratch or from other data sources; or convert between tabular file formats. Trigger especially when the user references a spreadsheet file by name or path — even casually (like \"the xlsx in my downloads\") — and wants something done to it or produced from it. Also trigger for cleaning or restructuring messy tabular data files (malformed rows, misplaced headers, junk data) into proper spreadsheets. The deliverable must be a spreadsheet file. Do NOT trigger when the primary deliverable is a Word document, HTML report, standalone Python script, database pipeline, or Google Sheets API integration, even if tabular data is involved."

proof-inventory
by tonyflo79
Catalog, classify, and score all available proof elements for a product or offer. Use after research (Skill 01) is complete and you need to build a comprehensive inventory of testimonials, clinical studies, data points, credentials, awards, media mentions, and other proof assets. Produces a scored proof inventory with gap analysis and promise ceiling calculation. The proof inventory determines what claims you can credibly make — without it, copy makes promises the proof can't support. Trigger when users mention proof inventory, testimonials, evidence audit, social proof, clinical proof, proof scoring, or promise ceiling. Requires research handoff from Skill 01.
arxiv-source-first-paper-ingest
by terrylica
Read an arXiv paper faithfully by fetching the authors' own LaTeX source instead of OCR-ing the PDF. Extracts every display equation with its label, environment and enclosing proposition, renders each to MathML, and proves usability by compiling each formula with a real TeX engine. Use when you need a paper's formulas exactly — to replicate a method, implement a loss function or custom objective, verify a quoted number, or check a claim against what the authors actually wrote. TRIGGERS - read this paper, get the paper, arxiv paper, extract formulas from a paper, replicate a method, implement the loss from, verify the paper's numbers, machine-readable paper, latex source, mathml, e-print.
