jev_call

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses almost nothing: it does not say that side effects depend entirely on the target tool, that arguments must match the target tool's schema, how errors are surfaced, or whether there is any validation. It adds only the example id format, which is a structural hint rather than behavioral transparency.

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 short sentences, no filler, with the core action front-loaded and the key parameter hint immediately after. Every clause earns its place.

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?

An output schema exists, so return values need not be described. What is missing for a dynamic proxy tool is the `arguments` contract and error/validation behavior when the chosen tool fails; the description is adequate as wiring but incomplete 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?

Schema coverage is 0% for both parameters, so the description must compensate. It does explain the `tool` parameter well ('the id from jev_route', with a concrete example like prometheus__execute_range_query), but says nothing about `arguments`, which is a free-form object whose contract (keys must mirror the target tool's schema) is the crux of using this tool correctly.

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 gives a specific verb ('Call') plus the resource being called, and explicitly ties itself to the sibling by stating the tool is 'chosen by jev_route'. That differentiates it from jev_route (which routes/selects) without opening either schema, though it doesn't spell out what 'calling' entails for the agent.

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 phrase 'the id from jev_route' implies jev_call must be invoked after jev_route, which is useful sequencing guidance. However, there is no explicit when-to-use/when-not, no statement that jev_route should not be used directly for execution, and no mention of what to do if the id is unknown.

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