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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so safety is fully covered. The description adds real scope context by naming the curated set of agencies the tool knows about and stating that results include official links plus Datamart's per-service capabilities. It says nothing about result counts, ranking, or what an empty match looks like.

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?

The operative sentence leads with the verb and resource and packs coverage, output content, and scope into one line. The trailing vendor attribution sentence ("Served by Profullstack...") is boilerplate that earns little place but is short.

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 single-optional-parameter read-only search with no output schema, the definition covers purpose, scope of coverage, and the shape of returned data. Combined with complete annotations, an agent has enough to call it correctly; only result-volume/ordering behavior is undocumented.

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?

Only one parameter with 100% schema description coverage, so the schema already explains `q` as a keyword with examples. The description reinforces that queries are keyword-based over service names but adds no syntax, matching, or scoring semantics beyond the schema. Baseline 3 applies.

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 ("Find") and resource ("government services") and enumerates the covered sources (IRS, Data.gov, California BizFile, FTB, DMV, EDD) plus what each result carries (official links, Datamart capabilities). That is enough to separate it from generic search siblings like profullstack_datagov_search or profullstack_fleet_search_services, though it never names an alternative 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?

There is no when-to-use or when-not-to-use guidance and no routing to sibling tools. The agency list and mention of official links imply this is a curated directory lookup, but the agent must infer that on its own.

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