collector_stickers_tradeable

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

With no annotations, the description carries the full burden and does well: it discloses the bounded GET, no auto-paging, 100-row and 256 KiB limits, truncation reporting, and refusal of oversized records. It also clarifies it doesn't list/transfer/buy. This is thorough, though the repeated mentions are redundant and the 'preserve' phrasing is unclear.

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 verbose and repetitive. Key limits (bounded GET, no paging, 100 rows/256 KiB) are stated multiple times, and the 'Makes one logical GET request' sentence is repeated. It could be cut by half without losing meaning. The structure is not front-loaded; it mixes critical behavior with redundant caveats.

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 tool is a simple read with one parameter and no output schema, the description covers operational constraints well but lacks a clear description of the return format. 'Preserve sticker identities...' hints at fields but doesn't explain the response structure or whether it's JSON, etc. It's adequate but not complete for an agent to fully anticipate the output.

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 0% and the description adds almost nothing about the 'player' parameter beyond the schema's name/type. It only says 'Required inputs reflect tool policy as well as measured upstream requirements,' which is unhelpful and doesn't specify what the player value should be (e.g., account name, ID). The description fails to compensate for low schema coverage.

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 states the tool reads one player's tradeable collector stickers, a specific verb+resource. It differentiates itself from the for-sale route and implies distinction from sibling collector_stickers by emphasizing 'tradeable'. However, it doesn't explicitly name sibling tools, so it's not a perfect 5.

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 description gives context that this is a read-only tool and not the for-sale route, but doesn't explicitly say when to use it vs alternatives like collector_stickers or market tools. The phrase 'Required inputs reflect tool policy' is vague and doesn't guide selection. No explicit when/when-not conditions are provided.

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