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

No annotations are provided, so the description carries the full burden. The verb 'List' signals a read-only operation, which is useful. However, it does not disclose ordering, response shape, recency semantics, or whether the listing reflects live state or cached data. Gaps exist but are moderate for a simple list 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 a single, front-loaded sentence with no filler. It is appropriately concise for a simple tool, though it could use the available space to add one or two useful details about behavior.

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 one-parameter read-only list tool, the description covers the basic action. But with no annotations and no output schema, it leaves several gaps: what a 'deploy' includes, how 'recent' is determined, the meaning of 'limit', and how this differs from sibling tools. It is minimally viable but not complete.

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%, and the description does not mention the only parameter, 'limit'. The schema provides the name and default (5), but the description does not compensate for the lack of parameter documentation. The parameter is self-evident by name, but the tool definition misses the opportunity to explain its effect.

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 a specific action and resource: 'List recent Render deploys for Jarvis.' The 'for Jarvis' scope helps distinguish it from sibling tools like neo_render_deploys. It lacks an explicit contrast with siblings or a definition of 'recent', but the core purpose 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?

There is no guidance about when to use this tool versus jarvis_render_logs, jarvis_render_status, or neo_render_deploys. The description implies a Jarvis-scoped deploy listing but does not state when to prefer it or when to use an alternative.

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