This skill pairs a Claude Code session with an OpenAI Codex CLI session for seamless communication, eliminating the need for copy-paste. It establishes a background listener and file-based message passing, providing Claude with send/recv/ask primitives.

A skill for writing voice authentication and AI-smell elimination. It activates when the user wants AI-generated writing to sound specifically like them, analyzing a writing sample to replicate their unique style.

Safe Create/Read/Update/Delete operations for Obsidian Vault notes. Implements atomic writes, advisory locking, concurrent edit detection, and lossless YAML frontmatter handling. Use when reading, writing, updating, or appending to any vault note.

Core markdown syntax skill for Obsidian. Enforces strict parsing and authoring of Obsidian proprietary syntax (Wikilinks, Blocks, Headings, Aliases, Embeds, Callouts). Use when reading, writing, or validating Obsidian-flavored markdown.

Use when the user wants to "model a problem", "translate to math", "formalize a problem", "mathematical modeling", "how to model this", "set up the math", "define the problem", "what kind of problem is this", or discusses translating real-world problems into formal mathematical structures. Covers any computational domain — discrete, continuous, statistical, or hybrid.

Generate images with xAI's Grok image models (grok-2-image / grok-2-image-1212). Use when the user asks for Grok-generated images, mentions xAI image generation, or wants an OpenAI-compatible image API alternative. Generation only — Grok image models do not support edit, mask, or reference-image inputs.

List and tuple patterns for bioinformatics — codon splitting, gene coordinate records, named tuples, sorting by GC/length, and copy pitfalls.

This skill covers lists and tuples in bioinformatics, including codon extraction, genomic coordinate records, named tuples, and copy semantics, focusing exclusively on bio-specific patterns.

Coding conventions enforcement agent. Auto-invoked when writing new code, reviewing code quality, adding headers, or checking documentation compliance across Python, TypeScript/JavaScript, and C#/.NET.

Conversion copywriting formulas, headline templates, email copy patterns, landing page structures, CTA optimization, and writing style extraction. Activate for writing high-converting copy, crafting headlines, email campaigns, landing pages, or applying custom writing styles from assets/writing-styles/ directory.

Analyzes any website page against Google's official AI Optimization Guide, debunked myths, and broader AI search landscape standards (Perplexity, ChatGPT, Gemini, Copilot). Use this skill to audit a page URL or content for AI search visibility.

Prefer the convert function from the convertible library over individual conversion functions like pack, unpack, decodeUtf8, and encodeUtf8. Use when writing or reviewing Haskell code that converts between types.
