-Chromium 152.0.7977.42 with the image's default WebMCP flags exposes `reserve_table` with string name/date fields, a numeric party size with bounds, and a seating enum. It adds a date format hint to the field description. Both top-level and embedded invocations return `completed` and the submitted values; the tests also read the DOM through `/playwright/execute` to verify native agent submission occurred exactly once. Discovery and invocation responses are logged by the test. Missing declarative tools fail the test rather than silently skipping supported behavior.
