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

Annotations already declare readOnlyHint, idempotentHint and openWorldHint, so safety is covered; the description adds real behavioral detail beyond them, namely product-specific default sections and that "all" returns sections in reading order. It also clarifies a domain nuance that the publish flow is a download step, which prevents a wrong lookup. Return shape/pagination is not described, but a static doc fetch has little to disclose.

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?

Purpose is front-loaded and every clause is dense but relevant; the per-product section lists map cleanly onto the enum values. It is somewhat long for a two-parameter fetch, and the embedded note about publishing via .style download is guide content rather than invocation guidance, which is minor waste.

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 simple read-only documentation fetch with full schema coverage and annotations carrying the safety profile, the description covers selection, defaults and ordering. The only omission is any hint of output size or format, which matters modestly given there is no output schema and "all" can return a large set.

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 baseline is 3, but the description exceeds it by spelling out what each product's default section actually is (mcp-server → usage-guidelines, map-studio → overview) and what "all" yields. That is meaning the enum schema alone does not convey.

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 ("Return the official documentation for a Magic Lane product") and enumerates the exact products covered, so the agent knows precisely what comes back. The closing clause ("questions about the products themselves rather than the Maps SDKs") implicitly separates it from read_doc/search_docs/find_across_sdks, though it never names those siblings directly.

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?

Gives a clear when-to-use rule (product-level questions, not SDK questions) plus concrete defaults per product and the meaning of section "all" in reading order. It stops short of naming an explicit alternative tool to use for SDK questions, leaving that routing to inference.

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