Perform TypeScript/JavaScript symbol rename through `typescript-language-server` over stdio. Use when you need workspace-aware rename edits that respect imports, path aliases, re-exports, overloads, and TypeScript project semantics instead of text replacement.
Perform LSP Call Hierarchy for TypeScript/JavaScript by talking to `typescript-language-server` over stdio. Use when you need “who calls this?” / “what does this call?” answers that respect TS project semantics (re-exports, path aliases, overloads), instead of search-based heuristics.
Perform TypeScript/JavaScript “go to definition” by talking to `typescript-language-server` over stdio (real LSP JSON-RPC). Use when you need accurate symbol resolution across a TS project and want to avoid heuristic search (ripgrep), especially for re-exports, path aliases, overloads, and workspace-aware resolution.
Create clean, conventional commits without pushing. Use when the user asks to "commit", wants a generated commit message, wants add-all staging, or wants commits split logically based on git diff analysis.
Create Excalidraw diagram JSON files that make visual arguments. Use when the user wants to visualize workflows, architectures, or concepts.
Persistent browser and Electron interaction through `js_repl` for fast iterative UI debugging.
Use when the task requires automating a real browser from the terminal (navigation, form filling, snapshots, screenshots, data extraction, UI-flow debugging) via `playwright-cli` or the bundled wrapper script.
