replicate_get_prediction

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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and openWorld, so the safety profile is covered. The description adds the useful fact that the call returns both status and output, but says nothing about polling cadence, terminal statuses, or what an expired/unknown prediction id yields.

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?

A single front-loaded sentence with no filler. It is efficient, though the brevity is part of why parameter and usage detail are absent.

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 two-parameter read tool with annotations covering safety, the description is roughly sufficient, and it does disclose that output is returned despite there being no output schema. It still leaves the caller without any indication of how to obtain or format the prediction_id, which is the main gap.

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%, so neither api_token nor prediction_id is documented anywhere. The description does not explain where a prediction_id comes from or what form it takes, leaving the agent to guess at the only non-obvious parameter.

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 ('Get the status and output of a Replicate prediction') so the agent knows exactly what the call retrieves. It does not explicitly distinguish itself from siblings like replicate_list_predictions or replicate_cancel_prediction, but the verb/resource pairing 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?

The description gives no when-to-use guidance, no prerequisites, and never names an alternative such as replicate_list_predictions or replicate_create_prediction. The agent must infer that this is the follow-up call after a prediction is created.

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