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

The readOnlyHint annotation already establishes this as a safe, non-mutating operation, so the description need not restate that. It does sketch the response content (sections with URLs and descriptions), which is useful, but says nothing about caching, freshness, or how the locale changes output behavior. Adequate but thin on behavioral context.

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 tool's output front-loaded and the usage cue second; nothing is wasted. The phrase "Radix Community web" is slightly informal but still parses clearly.

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 low-complexity, single-parameter, read-only tool with no output schema, the description covers what it returns (sections, URLs, offerings) and when to reach for it. Only minor ambiguity remains about the exact response format (structured data vs. prose).

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 description coverage is 100% and the single locale parameter is documented in the schema with an enum and default, so the schema does the heavy lifting. The description never mentions locale at all, so it adds no meaning beyond the structured field — this is the baseline 3 case.

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 states a concrete deliverable: a map of the Radix Community site listing every section with its URL and contents. That distinguishes it from content-fetching siblings like read_radix_doc and search_radix_docs, though it never names those siblings directly. It is clear but does not explicitly contrast itself with them.

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?

"Call it first when you need to know where something lives on the site" gives an explicit usage condition and positions the tool as a discovery/orientation step. It stops short of naming the alternative tools (search_radix_docs, read_radix_doc) or stating when not to use it.

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