render_trigger_deploy

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

With no annotations, the description must disclose behavioral traits. It provides none: no mention of whether the deploy is asynchronous, if it returns immediately, side effects, or required permissions. The agent receives no insight into what happens after triggering.

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 extremely short—a single sentence that only states the basic purpose. It sacrifices helpful detail for brevity. While concise, it is under-specified and could easily include more context without becoming verbose.

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?

Given the complexity of triggering a deploy (often involves async operations, potential errors, build processes) and the lack of output schema or detailed schema, the description is severely incomplete. It does not explain return values, error cases, or what constitutes a successful trigger.

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 no meaning beyond the schema. It does not explain that 'api_key' may be needed for authentication, 'service_id' identifies the service, or that 'clear_cache' clears the build cache. Schema coverage is 33% with only 'clear_cache' documented; the description fails 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 the tool triggers a deploy for a Render service. The verb 'Trigger' and resource 'deploy' are specific. It distinguishes from sibling tools like 'render_list_deploys' and 'render_get_service' which are for listing or retrieving, not triggering.

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 tool versus alternatives. It lacks context like prerequisites (e.g., a service must exist) or hints about typical use cases such as triggering after code push.

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