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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered by structured data and the description is not obliged to repeat it. However, the description adds nothing beyond that — not what the tool emits (form text? filled document?), nor what it does with the two required inputs. A single clause on output would have earned more.

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?

Three words is not conciseness, it is under-specification — there is no front-loaded verb-plus-object-plus-scope statement. Nothing in the fragment is wasted, but nothing earns its place either.

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?

With 7 undocumented parameters, no output schema, and a generation-style tool whose output format is entirely unknown, this description leaves an agent unable to call the tool correctly. It should state what document is produced and what each input field means.

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% across 7 parameters (property, landlord, rent, deposit, fee, moveIn, pets), and the description explains none of them. It does not clarify formats for rent/deposit/fee strings or the moveIn date. This is a significant gap the description fully fails to compensate for.

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?

"Rental application maker" restates the tool name and annotation title almost verbatim, adding only the word "maker." An agent can infer it produces a rental application document, but nothing distinguishes it from siblings like business_lease_draft or business_eviction_notice_draft beyond the noun.

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 gives no when-to-use guidance, no prerequisites, and names no alternative. There is nothing telling an agent when to pick this over business_lease_draft or business_contract_pack.

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