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

The readOnlyHint=true annotation already tells the agent this is a safe read, and the description adds essentially nothing behavioral beyond restating that it lists deployments and echoing the REST route. No mention of pagination, result ordering, or whether accounts without deployments return empty.

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?

Two tight sentences with the purpose front-loaded and no filler. The REST endpoint reference ('GET /deploy/list') earns marginal value for traceability but is not actionable for an agent, keeping it just below a 5.

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 simple, annotation-covered read-only list tool with a fully documented single parameter, this is minimally adequate. However, with no output schema, the description still leaves the return contents and any pagination behavior unaddressed.

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 100% and the single 'status' parameter is fully documented in the schema, so the baseline is 3. The description does not mention the status filter at all, adding no meaning beyond structured data.

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 ('List the account's dedicated deployments'), and the plural vs. the sibling 'deepinfra_get_deployment' (singular) implicitly separates listing from fetching one. It does not explicitly name or contrast with any sibling, so it stops short of a 5.

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?

No guidance on when to use this versus alternatives such as deepinfra_get_deployment (single, by id) or deepinfra_get_deployment_stats. Usage is only implied by the name; no conditions, prerequisites, or exclusions are given.

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