Sdk Acquire Project Lease

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

Annotations already declare readOnlyHint=false, destructiveHint=false, and idempotentHint=true. The description adds useful behavioral context beyond annotations: the lease is exclusive, short-lived, and returns an opaque in-process session reference. It does not explain what happens if the lease is already held, whether the caller must release it, or how TTL and process_id affect behavior.

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 front-loaded sentence with no wasted words. It is appropriately concise, though its brevity contributes to gaps in usage and parameter guidance.

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?

The tool has an output schema and annotations, but the description omits lifecycle context that matters for a lease operation: TTL meaning, relationship to renew/release siblings, and whether the returned session reference must be used with specific follow-up tools. It is too thin for a stateful SDK lease acquisition.

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% for three parameters. The description gives a semantic hint for expected_project_uri by saying it targets a precise saved .aprx, but it says nothing about ttl_seconds or process_id. With low schema coverage, the description does not compensate for the missing parameter documentation.

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 states a specific verb (acquire) and resource (SDK exclusive short lease for a saved .aprx), and adds that it returns an opaque in-process session reference. It does not explicitly differentiate itself from sibling tools such as arcgis_pro_sdk_renew_project_lease or arcgis_pro_sdk_release_project_lease.

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 guidance on when to use this tool versus alternatives like renewing or releasing a project lease. The description implies a lease lifecycle but does not state prerequisites, timing, or when another sibling is more appropriate.

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