This skill should be used when the user asks to "create an excalidraw diagram", "generate a diagram in Obsidian", "add a diagram to my vault", "embed a diagram", "make a flowchart", "visualize relationships", "draw a network diagram", or wants to programmatically generate .excalidraw files for an Obsidian vault. Also use when the user asks to update or regenerate an existing diagram file.
This skill should be used when the user asks to "manage Obsidian vault", "create a daily note", "move notes without breaking links", "search vault content", or "organize Obsidian notes". Automatically activates when working with Obsidian vaults, markdown notes with [[wiki-links]], daily notes, templates, or tags. Not for general markdown editing outside Obsidian vaults.
This skill should be used when the user asks to "start a service in tmux", "check tmux pane output", "manage background processes", or "run a server in a pane". Automatically activates when running in a TMUX session (detected by SessionStart hook). Not for one-off commands that do not need a persistent pane.
This skill should be used when the user asks to "build an iOS app", "create a SwiftUI view", "fix Xcode build errors", "implement Core Data", "design app architecture", or "optimize Swift performance". Automatically activates when working with .swift files, Xcode projects (.xcodeproj, .xcworkspace), SwiftUI interfaces, or Apple platform frameworks (UIKit, Core Data, Combine, WidgetKit, App Intents). Not for cross-platform frameworks (React Native, Flutter), non-Apple platforms, or backend server development.
This skill should be used when the user asks to "analyze data with SQLite", "query logs", "find patterns in test results", or "correlate errors across files". Automatically activates when parsing large output (>100 lines), correlating data from multiple sources, tracking state across operations, aggregating results (counts, averages, grouping), or querying the same dataset multiple times. Not for tiny datasets (<50 records) with a single simple query.
This skill should be used when the user asks to "find which commit broke this", "debug a regression", "bisect to find the bug", or says "this used to work". Automatically activates for performance regressions, test failures that appeared recently, or any issue known to have worked at a previous commit. Can be invoked from systematic-debugging or used standalone. Not for general debugging without a known-good commit or regression history.
This skill should be used when the user asks to "generate a PDF from markdown", "create a printable book", "convert documentation to PDF", or "export chapters as a PDF". Automatically activates when producing a PDF from a directory of ordered markdown chapters using pandoc and weasyprint. Not for single-file markdown-to-PDF conversion or non-documentation use cases.
This skill should be used when the user asks to "write a README", "create API documentation", "draft release notes", "write a tutorial", "structure documentation", or "review docs for clarity". Automatically activates when working with .md files in docs/ directories, README files, or when discussing documentation structure, style guides, or content organization. Not for creative/marketing writing, academic papers, code comments/docstrings, or internal chat.
