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

No annotations exist, so the description carries the full burden; it implies a read-only aggregate lookup and hints that status is fetched live, which is mildly useful behavioral context. It says nothing about authentication, rate limits, response shape, or whether it is a one-shot bootstrap call versus something to re-poll.

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, and the enumerated payload is the most useful part. The list is slightly dense but every item adds informational value.

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?

With no output schema, the description does the necessary work of naming what comes back, which is the key requirement here. It falls short by not clarifying its relationship to the overlapping discovery siblings, which is the main ambiguity an agent faces when choosing this tool.

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 takes zero parameters, so there is nothing for the description to disambiguate; the baseline of 4 applies. The description correctly implies a no-argument, whole-platform snapshot call.

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 uses a clear verb ('Discover') and enumerates the payload (tools, spec URLs, MCP/PTP endpoints, SDK info, tiers, status), so the resource is identifiable. However, with siblings named pabandi_discover, pabandi_platform_discovery and pabandi_platform_access, the description makes no attempt to distinguish this from those near-identical discovery tools, leaving the agent unable to tell which one to pick.

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 when-to-use guidance, no stated preconditions, and no mention of alternatives among the three sibling discovery/access tools. The agent must infer usage purely from the enumerated payload.

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