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

No annotations are supplied, so the description carries the full behavioral burden. It discloses that the lookup can be keyword-driven and that the corpus is informational/read-only by nature, but says nothing about how many answers come back, whether an unmatched query returns an empty result or a fallback, or the response shape. Adequate for a simple read tool, but thin given zero annotation coverage.

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 with no filler; the topical scope is front-loaded and the query hint follows. Efficient and readable.

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-optional-parameter read-only FAQ lookup with no output schema and no annotations, the description supplies enough to call it correctly — what it covers and how to narrow results. Only the absence of any behavioral/return expectations keeps it from a 5.

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% and the single parameter already documents its keyword semantics with examples, so the baseline is 3. The description's note that query may be passed for FAQ search adds only marginal framing beyond 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?

The description states a specific resource — answers to frequently asked questions — and enumerates the covered topics (factory, machines, prices, warranty, delivery, training, payback), so an agent knows exactly what content lives here. It does not explicitly differentiate itself from the nearest sibling (ask_manager or get_company_info), which keeps it just below a 5.

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 only implied: the reader infers this is the tool to call for canned FAQ content and that the optional query narrows the lookup. There is no statement of when to prefer this over ask_manager for a general question, nor any exclusion or prerequisite.

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