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

Annotations already flag openWorldHint=true and readOnlyHint=false, but the description adds genuinely non-obvious consequences: the user's email is shared with a third party and 'the law firm will follow up at that address'. It also discloses the return value. It stops short of covering failure behavior or whether repeat calls duplicate the email.

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-loaded with the action and the options, and the consent warning is capitalized and placed where it will be read. The single-sentence enumeration is dense but every clause carries information; minor cost is readability of the packed parentheticals.

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 two-parameter, no-output-schema tool, the description covers what it does, what each option yields, the consent gate, third-party follow-up, and the return shape ('list of PDF download links'). Nothing an agent needs to call it correctly is missing.

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%, so the baseline would be 3, but the description goes further by explaining what each enum value actually contains (5/10/30-Day notices, no-lease and squatter packet, exit-readiness worksheets), which the bare enum labels do not convey.

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 ('Request a free pack of Illinois legal form PDFs by email') and enumerates the three pack values inline, so the agent knows exactly what is being produced and against which options.

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 an explicit precondition ('only call this with the user's explicit consent to share their email address'), which is the key gating condition for this tool. It does not name sibling tools or contrast with them, but the siblings address unrelated tasks, so no ambiguity arises.

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