get_sender_setup_checklist

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

With no annotations, the description carries the burden of behavioral disclosure. It transparently states that the tool returns a checklist and lists all 10 components, giving a clear expectation of the output. It does not mention side effects or prerequisites, but as a simple getter, this is sufficient.

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 description is a single, well-structured sentence. It front-loads the key outcome ('Returns the 10-step checklist') and then provides a compact, comma-separated enumeration of the included items, with zero wasted words.

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 tool's simplicity (zero parameters, no output schema), the description is fully complete. It names the exact artifact and enumerates all steps, leaving no ambiguity about the return content. The sibling context further clarifies its niche, but the description alone is sufficient.

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?

The tool has zero parameters, and the baseline for no parameters is 4. The description adds value by detailing the content of the returned checklist, which is the only relevant semantic aspect. There are no parameter semantics to clarify.

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 uses a specific verb 'Returns' and identifies the exact resource: the 10-step cold-email infrastructure checklist. It clearly distinguishes itself from sibling tools by naming its unique deliverable and enumerating its contents.

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 states what the tool returns but provides no guidance on when to use it versus alternatives like diagnose_campaign or audit_spam_triggers. There is no mention of scenarios or exclusions, leaving the agent to infer usage solely from the tool's name.

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