Resolve start.gg URL

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

Annotations already declare readOnlyHint=true, so the description doesn't need to restate that. It adds a helpful output example but discloses no further behavioral traits (e.g., error handling, rate limits, or edge cases like invalid slugs). This is adequate but not rich beyond the annotation.

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 sentences plus a compact example with zero filler. The core action is front-loaded, and the example is tightly scoped. Every element 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?

For a single-parameter resolver with no output schema, the description gives purpose, usage, and a return-shape hint via the example. It doesn't mention error behavior, but that is a minor gap given the tool's simplicity and the read-only annotation.

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 100% and the schema already describes 'URL, path, or slug'. The description adds specificity by stating 'tournament or event URL (or slug)' and provides a concrete example that clarifies the expected format, going slightly beyond the schema description.

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 a specific verb ('Turn... into'), a resource (start.gg URL/slug), and the exact output (internal ids and slugs). The concrete example clarifies the input and output shape, and it is clearly distinct from the sibling search/get tools, which operate on identifiers rather than URLs.

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?

Explicitly instructs to use this tool first when a start.gg link is pasted, then call other tools with the returned ids. This provides a clear workflow and sequencing, leaving no ambiguity about when to select this tool over alternatives.

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