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

With no annotations provided, the description carries the full behavioral burden; it does disclose the output shape (confidence probabilities, bull/bear decomposition, catalysts, citations) and the 25-question cap, which is genuine context. It omits cost/latency implications of a batch call, auth requirements, and how failures among the 25 questions are handled.

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?

One front-loaded sentence that leads with the action and the cap before enumerating outputs. The output list is somewhat dense but each element is informative, not filler.

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 needn't be re-explained, but with six undocumented parameters, zero annotations, and ambiguous nullable items/questions arrays, the description leaves an agent unable to determine which parameter to populate or how batching limits interact with concurrency_limit.

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% across 6 parameters. The description only implicitly explains the 25-item cap, leaving items vs questions (two overlapping nullable arrays), variant, evidence_top_k, attach_evidence, and concurrency_limit completely undocumented. It does not compensate for the coverage gap.

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 ('Submit ... forecasting questions concurrently') plus a batch size cap, which distinguishes it from the singular foresea_forecast sibling. However it never names that sibling explicitly, so the differentiator must be inferred from the word 'batch'.

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 'up to 25 questions concurrently' framing implies this is the bulk counterpart to a single-question forecast, but there is no explicit when-to-use, when-not-to-use, or named alternative. Usage must be inferred from the sibling list rather than the text.

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