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

Annotations already cover read-only, idempotent, and open-world behavior. The description adds meaningful context beyond that: stamps are earned only by physically standing at the location with the free Headed Back app, which is important behavioral context for an agent.

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?

The description is reasonably sized and most sentences earn their place by conveying scope, mechanics, and usage. The long parenthetical stamp examples are somewhat decorative but still help convey the tool's domain and are front-loaded enough to orient the reader.

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?

Given the annotations and the fully described parameter schema, the description gives an agent enough to call the tool correctly. It does not explain the return shape, but with no output schema and a simple retrieval purpose, that omission is minor.

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 100%, so the baseline is 3, but the description adds value by explaining the alternative query modes and listing all 11 region page IDs, which the schema does not fully enumerate. It also clarifies that position input is for finding the closest stamps.

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 clearly identifies a specific resource: the Florida Passport stamp book with 55 stamps across 11 region pages. It implies retrieval by position, page, or name, which is understandable, though it never explicitly states 'returns stamps' and does not directly distinguish itself from broader siblings like find_places.

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?

It gives clear usage contexts such as Florida bucket lists, road-trip stops, and 'what should we not miss,' and explains the three query modes. It does not name alternatives or say when not to use this tool, so it stops short of full routing guidance.

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