bazaar_showcase

bazaar_showcase. WHEN: pin one owned asset on your profile. COSTS 5 Bazaar Credits (simulated, burned) on every successful pin/re-pin. Requires confirm:true — no silent charge. Response includes fee_charged. Differs from bazaar_create_listing (puts it on the market). Example: bazaar_showcase {"asset_id":"<asset_id>","confirm":""}

A4.6/5.0

Behavior5/5

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

Adds substantial context beyond the annotations: a 5-Credit fee is burned on every successful pin AND re-pin, confirm:true is mandatory so there is no silent charge, and the response carries fee_charged. This cost/reversibility information is exactly what the readOnlyHint/destructiveHint flags cannot express, and it is consistent with idempotentHint=false (re-pin charges again).

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Dense, front-loaded telegraphic style: WHEN, cost, confirm requirement, response field, sibling differentiation, then an example — nothing wasted. Minor deduction for the leading 'bazaar_showcase.' echoing the tool name, which carries no information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Covers the prerequisite (ownership of the asset), the mandatory confirmation gate, the economic side effect, and points at fee_charged in the response; with an output schema present it does not need to enumerate return values. Nothing an agent needs in order to call this safely is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so both required parameters are already documented in the schema, and the description largely restates the confirm:true fee gate. The inline example invocation is a small value-add but no new semantics for asset_id or the auth 'key' parameter are introduced beyond the schema.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

States a specific verb+resource: pin one owned asset on your profile. It also names the adjacent capability it is not (bazaar_create_listing, which puts the asset on the market), so an agent can distinguish it from the many bazaar_* siblings without opening a schema.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The 'WHEN:' clause gives the exact triggering condition (pinning an owned asset on a profile) and the 'Differs from bazaar_create_listing' clause names the alternative plus the discriminator (market listing vs. profile pin). When-to-use and when-not-to-use are both explicit.

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