predict_chronos

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

No annotations are provided, so the description carries the burden of behavioral disclosure. It adds some useful context: the tool produces multi-step forecasts, defines horizon semantics, and mentions that output includes a build fingerprint. However, it does not disclose the output format, whether it is a read-only operation, or any side effects.

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 compact and front-loaded with the core purpose. Every clause adds useful information—model identity, prediction type, horizon semantics, and build fingerprint—without any filler or redundancy.

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 3-parameter tool with no output schema and no annotations, the description is incomplete. It omits usage guidance, parameter details for symbol and period, return structure, and any behavioral context beyond horizon and fingerprint. An agent would need to infer too much.

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 explains only one of three parameters: horizon, including its format and allowed values ('1d/2d/5d/10d'). Symbol and period are not described, so the description only partially compensates for the missing schema coverage.

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 it is a Chronos-2 multi-step forecasting tool, which clearly identifies the resource (Chronos-2 model) and the action (multi-step prediction). It differentiates from siblings like predict_timesfm and predict_ensemble by naming the specific model, though it does not explicitly mention that a symbol must be provided.

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 choose this tool over predict_timesfm, predict_ensemble, or other siblings. The mention of 'Chronos-2' implies model-specific usage, but there are no conditions, exclusions, or alternative recommendations.

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