Save this receptionist and get the next step

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

No annotations provided, so the description carries full burden. It discloses that the tool saves, emails, includes a live demo number and signup link, and requires consent. It does not mention any destructive actions. Could be more explicit about what happens if consent is false, but overall clear.

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: first packs key actions (save, email, demo number, signup link), second gives guidance on when to use. Effective but the first sentence is long; could be slightly tighter.

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?

Given the output schema exists (not shown but stated), the description need not explain return values. It covers the save-email action, consent requirement, and clear linkage to prior tools. Complete for a tool with 7 parameters and specific usage context.

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 coverage is 100%, baseline 3. The description adds value by explaining the purpose of consent ('must explicitly agree'), the linkage to prior tools, and the context for when to call. This goes beyond the schema alone.

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 specifies the verb 'save' and the resource (phone script, IVR menu, agent prompt, or simulated call) and clearly distinguishes from siblings by listing exactly which preceding tools it follows (write_phone_script, write_ivr_menu, generate_elevenlabs_agent_prompt, simulate_receptionist_call).

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?

The description explicitly states when to offer this tool ('after write_phone_script... once the human seems to want to keep the result or try it live') and that it requires explicit consent. No explicit exclusion of alternatives, but context is clear.

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