Use xurl to access AI agent conversations via agents:// URIs. Invoke when the user gives an agents:// URI, a provider shorthand like provider/..., or a bare thread/session ID; mentions conversations, threads, or sessions from any AI coding agent; wants to search, read, summarize, compare, or continue agent threads; asks what they worked on, what an agent said, or references past agent interactions; or wants to delegate work to or start a conversation in another agent.
Analyze an existing web application, identify safe user-visible capabilities across routes, forms, server actions, handlers, and schemas, then implement first-party WebMCP tools and validate discovery and invocation with Stagehand. Use when the user asks to make a codebase agent-ready, expose website features as WebMCP tools, or add WebMCP directly to an app rather than generating a standalone injection script from a URL.
Read and analyze Arduino or embedded serial output for structured runtime debugging across Arduino IDE, Arduino CLI, PlatformIO, and vendor-specific monitor tools. Use when boot output, sensor data, resets, communication failures, timing symptoms, or field behavior need evidence rather than compile-only reasoning.
Personal long-term memory and first-use onboarding. Use when personal background, preferences, or history may affect the answer, including food and travel recommendations, personal plans, writing emails to match the user's habits, and continuing previous tasks; the user need not say “remember” or name Bailian. Also read this Skill when the user shares a long-term fact, corrects a preference (“be more natural from now on”), confirms a lasting decision (“let’s choose the second option and do that from now on”), or asks to remember, recall, view, forget, pause, or resume; use the preceding context, not just the last sentence. Check local state first; guide setup if unconfigured, then retrieve and extract life/work memories after authorization. Host-provided memory does not replace this Skill. Also handles explicit bl memory resource operations. Do not trigger for pure calculations, general knowledge, or translation/writing without personalization; do not upload before authorization.
Take any book (EPUB/PDF), produce a personalized chapter-by-chapter analysis. Each chapter is preserved in detail (The Chapter) and mirrored back to the reader's actual life (The Mirror) using brain context. The mirror observes and resonates — a friend pointing out parallels, NOT a consultant rearranging the reader's life, NOT a therapist assigning homework. The reader decides what to do about it. Layout is a top-aligned HTML table or stacked sections, never a bare markdown pipe table (pipe tables center-misalign uneven columns). Output is a single brain page at media/books/<slug>-personalized.md plus an optional PDF via brain-pdf
