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

No annotations are supplied, so the description carries the full burden. It does disclose the return shape (relevance-sorted, trust scores, capability badges), which is genuinely useful, but says nothing about permissions, rate limits, pagination, or what happens when no agents match.

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?

Two tight sentences with the capability statement front-loaded and the return shape second — nothing is padded. The brevity is only a problem insofar as it leaves the gaps above unfilled.

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 zero-required-parameter discovery tool with a fully annotated schema and no output schema, the description covers purpose and return shape adequately. It falls short on sibling differentiation and on the phantom 'location' dimension, which is exactly the kind of thing a discovery tool's description should get right.

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 100%, so the four parameters are already documented. The description does not add filter syntax or matching semantics beyond the schema, and worse, it advertises filtering 'by location' while no location parameter exists — a misleading claim that could send an agent looking for a filter it cannot pass.

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?

States a specific verb and resource ('Discover agents') plus the filter dimensions and return shape, so the operation itself is unambiguous. It does not, however, distinguish itself from the sibling pabandi_discover, which an agent would reasonably read as doing something very similar.

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, no exclusions, and no mention of the adjacent tools (pabandi_discover, pabandi_agent_registry, pabandi_agent_card) that plausibly compete for the same intent. The agent must guess which discovery entry point to call.

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