tools

ALWAYS use this skill when the user asks to build, modify, or audit a FrontMCP tool. Covers everything inside `@Tool({...})`: class and function-style tools, Zod input/output schemas with derived `execute()` types, dependency injection (`this.get` / `this.tryGet`), error handling (`this.fail`, MCP error classes), throttling (rate-limit / concurrency / timeout), auth providers (single / multi / vault), availability constraints (`availableWhen`), elicitation (`this.elicit`), interactive UI widgets via `@Tool({ ui })` (MCP Apps / SEP-1865 — including `.tsx` FileSource, CSP, `window.FrontMcpBridge`, host-detect `resourceMode`), annotations (`readOnlyHint` / `destructiveHint` / …), `examples` metadata, registration in `@App({ tools })`, and per-tool unit testing. Does NOT cover: - Read-only data exposed via a URI — use `create-resource` - Conversation templates / system prompts — use `create-prompt` - Multi-tool orchestration loops — use `create-agent` - Background work / pipelines — use `create-job` / `create-workflow` - Server-level config (transport, sessions, auth modes) — use `config` / `auth` Triggers: `@Tool`, ToolContext, tool decorator, MCP tool, snake_case tool name, inputSchema, outputSchema, ToolInputOf, ToolOutputOf, `@Tool({ ui })`, tool UI widget, MCP Apps widget, FileSource widget, `.tsx` widget, ui.csp, ui.resourceMode, window.FrontMcpBridge, tool annotations, readOnlyHint, destructiveHint, rate-limit tool, throttle tool, concurrency tool, tool timeout, this.fail, this.respond, this.fetch, this.notify, this.progress, this.elicit, ElicitationDisabledError, ToolContext.execute, this.get(TOKEN), this.tryGet, register tool in @App, tool examples metadata, availableWhen, missingAxes, `tool()` function builder, Tool.esm, Tool.remote, PublicMcpError, ResourceNotFoundError, MCP_ERROR_CODES, ui://widget.
