ht_oa_list_pickup_times

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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. Beyond that, the description usefully indicates the return values are clock-time strings ("10:15 AM" … "7:00 PM"), but says nothing about timezone, whether unlisted times mean unavailability, or how quickly results change for a live-availability read.

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?

A single well-formed sentence with the resource and scope front-loaded and a compact example of the returned format. No filler, though the parenthetical example slightly crowds the core statement.

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?

For a simple two-parameter read with no output schema, the essentials are present and the example values partially compensate for the missing output schema. It falls short on timezone/availability semantics and on the dependency chain to obtain departmentIds, which an agent needs for a correct first call.

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 coverage is 50%: only `date` carries a schema description ("YYYY-MM-DD"), while `departmentIds` has just a hex-ID pattern and a max of 10 items. The description restates both inputs but adds no guidance on sourcing department IDs, what a multi-department request returns, or how results combine across departments.

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?

The description names a specific verb (List) and resource (Order Ahead pickup times), plus the two scoping dimensions: a date and the given departments. An agent can tell it retrieves availability rather than placing an order, though it does not explicitly contrast with the similar-sounding ht_list_timeslots sibling.

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?

There is no when-to-use guidance, no statement of prerequisites, and no mention of the obvious alternative (ht_list_timeslots) or of where the departmentIds should come from (presumably ht_oa_list_departments). Usage must be inferred entirely from the required parameters.

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