Optimize markdown files for LLM consumption by adding YAML front-matter with metadata and TOC, normalizing heading hierarchy, removing noise and redundancy, converting verbose prose to structured formats, and identifying opportunities for Mermaid diagrams. Use when preparing technical documentation, notes, research, or knowledge base content for use as LLM reference material or in prompts.

Detects critical product, scope, data, risk, and success ambiguities in requirements or PRDs and expresses them as structured, decision-forcing clarification questions without proposing solutions or workflow actions.

Guides creation of high-quality MCP (Model Context Protocol) servers that enable LLMsto interact with external services through well-designed tools. Use when building MCPservers to integrate external APIs or services, whether in Python (FastMCP) orNode/TypeScript (MCP SDK). Covers tool design, authentication, Docker deployment,and evaluation creation. NOT when consuming existing MCP servers (use the server directly).

Use this skill for the requests related to USA census blocks; it provides a way to get blocks as a GeoDataframe in GeoPandas

Multi-faceted legal operations - generate formal court-ready contracts (senior attorney level) OR simplified explanatory versions. Extends Claude Code beyond coding to professional legal document generation.

Real-time voice AI knowledge including STT and TTS providers, LiveKit Agents plugins, and voice pipeline patterns. Use when working with speech-to-text, text-to-speech, voice agents, LiveKit, or any voice-related infrastructure.

This skill should be used when the user asks to "create a workflow", "make a slash command", "add a command", "automate a task with a command", "workflow vs plugin", "should this be a workflow or plugin", or needs guidance on Claude Code command structure, workflow design patterns, or determining appropriate scope for automation requests.

Write efficient BigQuery queries for Mozilla telemetry. Use when user asks about: Firefox DAU/MAU, telemetry queries, BigQuery Mozilla, baseline_clients, events_stream, search metrics, user counts, or Firefox data analysis.

Applies personalized Claude Code settings. Use when setting up Claude Code preferences on a new machine.

Decision memory and session logging for AI-assisted development. Use when tracking architectural decisions, maintaining context across sessions, implementing confidence protocols, or coordinating between agents. Triggers on "memory trail", "decision memory", "track decisions", "session logging", "why did we decide", "check past decisions".

Playwright modern end-to-end testing framework with cross-browser automation, auto-wait, and built-in test runner

Use the hack CLI for local dev environments (docker compose, logs, run commands) and agent integration setup. Trigger when asked to start/stop services, open project URLs, inspect logs, run commands in services, manage branch instances, or configure agent integrations (Cursor/Claude/Codex/MCP). Prefer CLI over MCP when shell access is available.

CNN architectures, object detection, image segmentation, and video processing.

Automatically reference and validate schemas from both legacy data sources and medallion layer data sources (bronze, silver, gold) before generating PySpark transformation code. This skill should be used proactively whenever PySpark ETL code generation is requested, ensuring accurate column names, data types, business logic, and cross-layer mappings are incorporated into the code.

This skill should be used when the user asks about "Ashby API", "how to use Ashby tools", "Ashby authentication", "Ashby MCP tools", "what can I do with Ashby", or needs help understanding available Ashby operations. Provides complete API documentation and tool usage guidance.

Convert any file to markdown format using the markitdown library. Use this skill when users need to convert documents (PDF, DOCX, XLSX, PPTX, images, HTML, CSV, JSON, XML, audio files, etc.) into markdown format for easier reading, editing, or integration into markdown-based workflows.

Add context to LOCAL BTR tree (NOT ByteRover/brv). Use `btr` CLI or `mcp__btr__*` MCP tools. Add or update context in the BTR tree with AI-powered metadata extraction. Use when the user wants to "add to context tree", "store this in BTR", "curate to BTR", or needs to organize knowledge with intelligent tagging.

Invoke this skill first when authoring any AI agent instructions. Foundational principles for writing LLM instructions (skills, CLAUDE.md, rules, commands). Covers token economics, imperative language, formatting for LLM parsing, emphasis modifiers, terminology consistency, and common anti-patterns.
