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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered; 'ready to print' adds a useful hint that the output is a finished document rather than persisted state. However it never says what form the result takes (plain text, Markdown, file), what happens when optional fields are omitted, or whether defaults are applied — notable gaps for a 16-parameter generator.

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 core sentence is front-loaded and economical. The trailing fragment 'A guide template.' is vague filler that spends words without adding actionable information, and the field list is compressed into a single clause.

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 16-parameter, zero-required document generator with no output schema and no per-parameter documentation, the description is far too thin: it does not state that all inputs are optional, which fields are required in practice, or what the returned document looks like. Annotations only cover the read-only/no-network side.

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 only 13%, so the description must carry the burden, and it only glosses landlord, tenant, premises, rent and term plus the language and use enums. Nine parameters (bills, every, notice, deposit, activity, date, months, type, start) receive no meaning from either the schema or the description, leaving an agent to guess at things like whether 'months' is a duration or a count.

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 names a specific verb and artifact ('Writes a ... lease agreement') and scopes it to residential or commercial, Arabic or English. It is clearest of the sibling set, though it does not explicitly contrast itself with property_listing_writer or publish_listing_page.

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?

There is no when-to-use guidance, no prerequisites, and no naming of alternatives among the four siblings. The trailing phrase 'A guide template' hints the output is non-binding but does not state when an agent should pick this versus drafting a listing.

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