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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety profile is covered. The description adds behavioral context beyond the annotations (B2B drop-off nature, lead time, per-weekday schedule), but since an output schema exists, listing return fields adds limited incremental value and no pagination/rate-limit notes are given.

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 dense sentence, front-loaded with the resource identity and trailing the discriminating detail about the B2B program. No filler or redundancy.

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 parameterless read-only list with an output schema, the description supplies what's needed: what the list is, how it differs from normal cafe locations, and roughly what fields it contains. It stops short of rich detail but nothing essential is missing.

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?

The tool takes zero parameters, so the baseline is 4. Nothing in the description misleads about inputs, and the schema fully covers the empty parameter set.

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 resource (the full national Panera at Work workplace-delivery location list) and immediately distinguishes it from the sibling panera_locations by characterizing it as 'a separate B2B drop-off program from ordinary cafe pickup/delivery.' An agent can tell which Panera location tool to call without opening any schema.

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?

The contrast with 'ordinary cafe pickup/delivery' implicitly tells the agent when to use this tool (B2B workplace-delivery queries) versus the regular cafe-location sibling. No explicit exclusions or named alternative tool, but the routing context is clear.

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