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

Goes well past the annotations: it discloses that step 1 persists nothing, that the confirm_token expires in 10 minutes, that step 2 actually sends the request to a human, and that follow-up occurs within one business day. That is exactly the write-path consequence an agent needs before a non-idempotent, open-world mutation.

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?

Front-loads the purpose, then walks the two steps in order, then the SLA and the safety gate. Dense but every clause carries operational meaning; only the 'for times that suit the person' preamble is slightly redundant with the conditions that follow.

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?

An output schema exists, so return values need not be described, and annotations already cover read-only/open-world semantics. For an 11-parameter two-step mutation, the description supplies the confirmation flow, persistence behavior, token TTL, and human follow-up timing.

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 0%, so the description must carry the load; it does explain confirm_token's role and lifetime and that step 2 needs 'the same details'. But 6 required parameters (location_id, preferred_times format, team_size, name/email/company) and the odd leave_empty field remain undocumented anywhere.

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 and resource ('Asks CANOPY's sales team to arrange a tour at a location') and scopes the eligible situations (booked-by-request, not yet open, no listed time works). It implies but never names the closest sibling book_tour, so the agent must infer the boundary between requesting a tour and booking a listed slot.

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?

Gives clear eligibility conditions for when this is the right call and a strong gating rule for the second step ('Only call step 2 after the person agrees'). What is missing is the explicit contrast case: use book_tour instead when a listed slot works, which get_tour_slots can enumerate.

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