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

With no annotations, the description fully carries the burden, and it does so richly: it reveals the measured six-object array shape, the set names, the exact fields and types, the absence of BCX/donor/account fields, the 24-hour caching, provenance behavior, and that rows are returned unchanged. This goes well beyond a generic list description.

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 densely informative but not bloated; every sentence provides distinct value: the endpoint, the response shape, the excluded fields, the cache behavior, and the unchanged-return guarantee. The core purpose is front-loaded.

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?

For a parameterless list endpoint with no output schema, the description is complete enough for an agent to call it correctly and interpret results. It covers what data is returned, what is absent, and how caching/provenance behave. Nothing critical is missing.

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 tool has zero parameters and an empty input schema, so there are no parameter semantics to document. Per the baseline for zero-parameter tools, a score of 4 is appropriate, and the description compensates by detailing the output structure instead.

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 names a specific verb ('List') and resource ('pack metadata rows returned by GET /cards/pack_data_wax'), and then distinguishes the data from per-card or per-owner data. This makes the tool's purpose unmistakable and differentiates it from siblings like cards_get_details or cards_collection.

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 provides useful context by stating that this is WAX-bridge mint/burn metadata and not per-card or per-owner data, implying when it should be selected. However, it does not explicitly name alternative tools or state when-not-to-use it, leaving some inference to the agent.

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