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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds real value beyond that by disclosing the return shape (titles, short descriptions, canonical URLs) and the intended downstream behavior of citing those URLs, which no structured field provides.

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 sentences, front-loaded with the verb and resource scope, and the return-value statement in sentence two does real work. The parenthetical topic enumeration is slightly long, but it doubles as query-vocabulary guidance, so it mostly earns its place.

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 two-parameter search tool with annotations and no output schema, the description covers scope, query domain, and return shape thoroughly. The only missing piece is explicit routing relative to the retrieve-by-name siblings, which matters given five tools in this namespace.

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 both parameters, including the default of 8 and the max of 20, are already documented in the schema. The parenthesized failure-mode list hints at the sort of query strings that work, but it adds only marginal semantic meaning beyond the schema's own example.

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 ("Search") and enumerates the resource types covered: grow profiles, troubleshooting guides with concrete topics, and blog posts. It's clearly distinguishable from get_profile/list_profiles in spirit, but it never names those siblings, so differentiation is inferred rather than stated.

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?

The content-type list implies when this tool is appropriate (topic discovery vs. fetching a specific profile), but there is no explicit when-to-use guidance and no routing to siblings like get_profile or get_chamber_guide. Usage is left to inference from the domain vocabulary.

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