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

No annotations exist, so the description bears the full burden; it does disclose the return payload (handles, trust scores, capabilities), which is genuinely useful since there is no output schema. It says nothing about read-only safety, pagination behavior, rate limits, or whether the list is filtered by caller identity.

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 short sentences with the purpose front-loaded and the return shape second. There is mild redundancy between "agent registry" and "listing all discoverable agents," but nothing wasteful.

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 one-parameter read tool with no output schema, naming the returned fields is the key contribution and it is present. Remaining gaps (pagination semantics, whether results are tenant-scoped) are minor but real.

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% and the single `limit` parameter is fully documented with a default, so the schema does the heavy lifting. The description adds no meaning beyond the schema, which is the expected baseline here.

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?

A specific verb+resource ("Get the agent registry") with a clear scope ("all discoverable agents on Pabandi") and a sketch of returned fields. However, it offers no differentiation from close siblings like pabandi_discover_agents and pabandi_agent_card, which an agent would need to choose between.

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?

There is no guidance on when to call this versus pabandi_discover_agents, pabandi_agent_card, or pabandi_trust_resolve. The only usage hint is implicit: that it is a bulk listing rather than a single lookup.

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