update_lease

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

There are no annotations, so the description carries the full burden. It only states the basic action and parameter shapes; it fails to disclose whether the update is partial or full replacement, validation requirements, side effects, or permission needs. This is a significant gap for a mutation tool.

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 concise and well-structured, with an action statement followed by a clean Args/Returns block. Every sentence earns its place without redundancy.

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?

Despite having only two parameters, the nested lease_data object is entirely undocumented in structure and allowed keys. The output schema exists but is not described, and the returns line 'Updated lease details' offers minimal information. For a mutation tool with no annotations, this is insufficient for correct invocation.

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 description adds some meaning beyond the raw schema: lease_id as 'The lease ID' and lease_data as a 'dictionary with fields to update', hinting at partial update semantics. However, it lacks details about valid fields, nested structure, or constraints, leaving schema coverage at 0% and forced to compensate.

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 clearly states 'Update an existing lease' with a specific verb and resource, distinguishing it from sibling tools like create_lease, get_lease, and list_leases. The scope is unambiguous.

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 implies usage through the verb 'update' and 'existing lease' but provides no explicit guidance on when to use this tool versus create_lease or get_lease. No alternatives or exclusions are mentioned.

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