getPredictionTimelineStages

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

The description explains the return (stages with status Done/Active/Upcoming) and is a read-only query. No annotations exist, so the description carries the burden; it adequately discloses behavior but could explicitly state it is read-only and safe.

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?

Three concise sentences front-load purpose, then example, then agent hint. No fluff; every sentence adds value.

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 simple one-parameter query, the description is fairly complete: explains return, gives example, and links to sibling. Lacks details on output format and error handling, but the tool's simplicity mitigates this.

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 schema has one string parameter without description (0% coverage). The description adds meaning by giving a concrete example (eventType=1 for FIFA 2026), helping the agent understand the value space. However, it does not enumerate all valid eventType values.

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 it queries the tournament stages timeline for a sports prediction event, listing the specific stages returned. It distinguishes from sibling tools like getPredictionGroupStageDetail.

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?

Provides explicit when-to-use: to understand the current tournament phase and navigate to the relevant stage. Includes a concrete example (FIFA 2026, eventType=1) and references the sibling tool getPredictionGroupStageDetail for further steps.

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