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

With no annotations, the description carries the full burden and does well: it discloses the result cap ('up to 10'), the provenance and neutrality of ratings ('unedited Google ratings'), and that pricing details are returned. It stops short of stating ranking/sort logic, behavior on empty results, or any auth/rate constraints.

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, no filler, with the search scope and filter axes front-loaded ahead of the return-value sentence. Every clause 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?

No output schema exists, and the description compensates by describing what comes back (up to 10 venues with ratings and pricing). All inputs are covered by a 100%-coverage schema, so the only gaps are behavioral edge cases rather than missing invocation-critical information.

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%, so all five parameters including both enums are already documented with examples, and the description adds little beyond restating the filter axes. The only marginal additions are framing budget as an 'envelope' and calling layout a 'setting', which do not materially extend the schema.

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+resource ('Search and filter ... venues') with a clearly bounded domain (verified Gauteng event/celebration venues) and enumerates the filter axes. An agent can tell this is the discovery/search tool, distinct from get_venue_details and request_curated_quotes.

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 implied by the phrasing — this is the search step that produces a curated shortlist before drilling into details or requesting quotes — but the description never says when to prefer it over get_venue_details or request_curated_quotes, nor what to do when zero results match. The context is clear enough to infer, but no explicit routing guidance is given.

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