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

Annotations already declare readOnlyHint=true, so safety is covered. The description adds that results are limited to the public gallery and that 'mine' is owner-scoped and token-gated, which is useful context, but it says nothing about result volume, ranking, or what happens when no token is supplied with 'mine' true.

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, purpose front-loaded, filters summarized in a single clause. No filler or repetition of schema detail.

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 read-only, fully documented, zero-required-parameter search with no output schema, the definition covers what the tool does and the notable 'mine' gating. It stops short of describing result shape or behavior when the owner token is missing, which would complete 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?

Schema coverage is 100%, so the schema already explains every parameter including the enum, page bounds, and the ownerToken default. The description merely summarizes the filter set without adding format, ranking, or combination semantics beyond what the schema provides.

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 ('Search the BrewPage public gallery'), making the operation immediately identifiable. No sibling tool competes for this use case, so it doesn't need explicit differentiation, but it also doesn't distinguish public-gallery scope beyond the phrase 'public gallery'.

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?

Lists the optional filters and notes that 'mine' requires an owner token, which implies usage context. However, it never states when to use this tool versus other retrieval siblings (get_page, get_json) or what kinds of content are searchable.

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