First tool wired — `schema` (no input args, returns schema.v1 JSON mirroring `kebab schema --json`). Establishes the per-tool module pattern (crates/kebab-mcp/src/tools/<name>.rs) + error helper that maps anyhow::Error to MCP CallToolResult.error with error.v1 content. Dispatch pattern: manual dispatch — explicit `list_tools` + `call_tool` overrides on `impl ServerHandler for KebabHandler` with a `match request.name.as_ref()` arm per tool. No proc-macro magic. Tasks 5-7 should add a new arm + new tools/<name>.rs following the same pattern; also add a `Tool::new(...)` entry in `list_tools`. API shapes confirmed from rmcp 1.6 source: - Content = Annotated<RawContent>; text via `Content::text(s)`; pattern match via `&content.raw` → `RawContent::Text(t)` → `t.text` - CallToolResult::success(Vec<Content>) / ::error(Vec<Content>) - ListToolsResult::with_all_items(Vec<Tool>) - schema_for_empty_input() from rmcp::handler::server::common Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
