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

No annotations are provided, so the description carries the full burden. It never states whether this is read-only, whether authentication or payment is required to hit the 'payment endpoint', whether access is rate-limited, or whether it fails on unknown IDs. 'Retrieve' weakly implies a read, but nothing substantive is disclosed.

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, front-loaded sentence with no filler. It is efficient, though it is arguably too terse for what it needs to convey.

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?

An output schema exists, so return values need not be described. However, for a tool with an undocumented required parameter, no annotations, and an unusual 'payment endpoint' aspect, the description leaves real gaps around input sourcing and access requirements.

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 description coverage is 0% and the single parameter is required, so the schema supplies no meaning. The description says nothing about what an asset_id looks like or where to obtain one (presumably from search_assets), leaving the caller without the info needed to invoke the tool.

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 gives a specific verb ('Retrieve') and resource ('AgentBridge knowledge asset metadata and payment endpoint'), so an agent can tell it apart from search_assets and fetch_web_page. It does not explicitly name its siblings, so it falls short of a 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?

No when-to-use guidance is given, and the obvious alternative (search_assets, for discovery before fetching) is never mentioned. The agent must infer that an asset_id is already known.

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