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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety and scope profile is covered structurally. The description's enumeration of topics tells the agent what content comes back, but adds nothing about format, length, or whether content is static versus dynamic — reasonable but not rich beyond the annotations.

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?

A single front-loaded sentence naming the resource followed by the topic list, plus a short no-argument note. The topic enumeration is informative but slightly list-heavy; every item does correspond to a plausible user question, so little is wasted.

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 no-argument, read-only info tool with annotations carrying the safety profile and no output schema required, the description covers what the agent needs to select and call it. The only missing piece is routing guidance relative to get_pricing and find_offices.

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?

Zero parameters, so the baseline is 4. The description reinforces this explicitly with 'Takes no arguments,' removing any doubt that the agent should call it bare with no payload.

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 ('Get general information') and resource (the lie detector test service), then enumerates the covered topics: offerings, booking, payment, service area, and post-booking. This is clear on its own, but it never explicitly distinguishes itself from siblings like get_pricing and find_offices, which overlap with the 'how payment works' and 'service area' topics it claims.

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: an agent can infer this is the orientation/FAQ tool to call before start_booking, but the description never says so or names alternatives. It does add 'Takes no arguments,' which signals a safe first call, yet there are no explicit when-to-use or when-not-to-use rules against the four sibling tools.

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