collector_stickers_tradeable

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

With no annotations present, the description carries the full burder and delivers a strong behavioral profile: read-only semantics, one bounded GET, no auto-paging, 100-row/256 KiB limits, truncation reporting, and refusal of oversized records without partial fields. It clearly discloses that nothing is listed, transferred, or purchased.

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 purpose sentence is front-loaded, but much of the description repeats itself: paging/request limits appear twice and the size cap (100 rows / 256 KiB) is stated in multiple. The 'Two public featured accounts...' example and awkward phrasing ('data list are locally limited') add clutter without earning their place.

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 one simple parameter, no annotations, and no output schema, the description covers the essential operational context: safety, size limits, pagination, truncation behavior, oversized-record refusal, and the caveat about forwarded filters. It stops short of describing the exact returned data structure, so it is not fully complete, but it is more than sufficient for a single-parameter read tool.

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 schema coverage is 0% and the only parameter, 'player', has no schema description. The description hints that 'player' identifies the subject ('one player's'), but never states the expected format (account name, ID, etc.) or how it maps to upstream requirements. The phrase 'Required inputs reflect tool policy...' adds no usable semantic detail.

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 states a specific action and resource ('Read one player's tradeable collector stickers') and adds delimiting scope with 'This is not the for-sale route and does not list, transfer or buy anything.' This clearly distinguishes the tool from market/listing siblings even without naming them explicitly.

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 a negative scoping statement ('not the for-sale route'), but no explicit 'use this when...' guidance or named alternatives like collector_stickers. The description implies usage based on the tool name rather than telling an agent when to choose it over its closest siblings.

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