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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds that the result is a set of pointers spanning docs, OpenAPI, help, webhooks and the MCP server itself, which hints at link-style output. It stops short of saying whether the return is URLs, names, or content summaries, which matters because there is no output schema.

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 compact sentence with the resource list front-loaded and no filler. It sacrifices a little clarity for brevity by omitting any verb, but nothing is wasted.

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 index tool the description covers the breadth of resources, which is most of what an agent needs. It is thin on output shape and trigger conditions, and with no output schema those gaps fall on the description to fill.

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 and the schema is fully self-describing. Baseline 4 applies.

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?

"Maple developer resources: OpenAPI, API catalog, docs, help, webhooks pointer, and this MCP server" enumerates what the tool exposes but never states what it does with a verb — no "returns", "lists", or "links to". The reader must infer it is a directory/index tool. It is at least unmistakable against siblings like get_pricing or list_integrations, none of which overlap.

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 when-not-to-use, and no mention of alternatives. The agent has to guess that this is the entry point for developer documentation discovery rather than, say, a product catalog lookup.

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