Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

Annotations already cover the safety profile (readOnlyHint=true, openWorldHint=true), so the bar is lower. The description usefully adds the shapes of data returned and cites the backing endpoint (GET /api/v1/back_of_house), but says nothing about result size, ordering, or whether 'today' is location-local time.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Is the description appropriately sized, front-loaded, and free of redundancy?

Two compact sentences with the core purpose front-loaded and no repetition. The '(Gingr's Digital Whiteboard)' parenthetical and API-path suffix are mildly redundant with the title but do add orientation value.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

With no output schema, the description compensates by enumerating the returned fields (owner/pet names, times, run, status) and scoping the query. It is adequately complete for a read-only reporting call, though it could clarify timezone/scoping semantics for 'today'.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents location_id, type_ids, full_day, and mins_future (including the cross-dependency between them). The description only echoes 'at a location' and 'by reservation type' without adding format or defaulting detail beyond the schema, so baseline 3 applies.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb ('Get') and a well-defined resource: today's checking-in/checking-out pets for a location, broken down by reservation type, with the fields returned (owner/pet names, times, run, status). This is clearly distinct from a generic reservation list, though it does not explicitly name sibling tools like gingr_list_checked_in or gingr_list_reservations to disambiguate.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Does the description explain when to use this tool, when not to, or what alternatives exist?

Usage is implied by the 'today's arrivals and departures' framing (a daily operations board), but there is no explicit when-to-use or when-not guidance and no named alternative for narrower queries (e.g., currently-checked-in pets). The full_day/mins_future note is a parameter behavior, not usage guidance.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
