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

Annotations already declare this a read-only, idempotent, non-destructive, closed-domain operation, so the safety profile is covered. The description adds value beyond that by disclosing the corpus boundary (free guides/checklists/tools) and the return shape (titles and links meant for citation). It says nothing about result counts or pagination, but for a single-query search that is minor.

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 search domain before the return-value note. The long parenthetical topic list is dense but earns its place by clarifying retrieval coverage; it does make the sentence heavier than necessary, keeping it off a 5.

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 one-parameter, read-only search with no output schema, the definition covers what the tool searches, who it serves, and what comes back (titles and links). Only the routing relationship to the overlapping sibling pricing/name tools is left unexplained.

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% with a single required `query` parameter that already includes worked examples ("start a cleaning business in Texas"). The description adds no query-syntax guidance, phrasing advice, or constraints beyond what the schema states, so it matches the baseline of 3.

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?

A specific verb ("Searches") plus a concrete resource scope (Broombook's free guides, checklists and tools) and an explicit enumeration of covered topics for two audiences (business owners, homeowners). An agent can tell this is a content-search tool rather than a calculator, which is what the sibling tools do.

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?

No explicit when-to-use vs. when-not wording and no named alternatives. The phrase "Returns titles and links to cite" implies this is for finding reference material rather than computing numbers, which implicitly routes agents away from pricing tools like price_house_cleaning and minimum_cleaning_price_by_state, but the description never says so and "pricing" is listed as a covered topic, leaving real overlap ambiguities unaddressed.

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