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

Annotations already establish readOnlyHint=true and openWorldHint=false, so the safety profile needs no restating. The description adds some value by disclosing the content shape (services explanation, how engagements start, page links), but says nothing about response format, caching, or typical size for what is effectively a static content fetch.

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 sentence, front-loaded with the subject and scope, that names the audience (B2B founders and executives) before the contents. No filler or repeated information.

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 and no parameters, the description carries the burden of previewing the return contents, and it does so by listing the three things the caller gets. Adequate for a simple read-only content tool; only a note on format or currency of the links would improve it.

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; per the baseline for parameterless tools a 4 is appropriate. No meaningful gap exists 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?

States the resource plainly: a human-readable overview of what Wise Mango does, with concrete detail (LinkedIn and Reddit content, founder-led AI visibility) and an enumeration of what the response contains. It is distinguishable from find_service_for (a matcher) and founder_ai_visibility_offer (a single offer), though it does not name those siblings explicitly.

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?

Usage is only implied: an agent must infer this is the 'browse the whole catalog' entry point versus find_service_for for a targeted match or free_resources for assets. No when-to-use or when-not-to-use statement, and no mention of the alternatives, but the framing as a general overview does signal the context.

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