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

Annotations already declare readOnlyHint=true and openWorldHint=true, so the safety profile is covered. The description adds a useful data caveat ('including older special rounds') but says nothing about permissions, rate limits, or completeness of history. With annotations carrying the behavioral burden, a 3 is appropriate.

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, no waste, with the resource description front-loaded and the parameter instruction second. Efficient and well-ordered.

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 low-complexity, single-parameter lookup with an output schema present (so return values need not be explained) and read-only annotations, the description is nearly complete. The only gap is where an agent obtains a valid slug, which keeps it from a 5.

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 0%, so the description must define the lone required 'slug'. It does add real meaning: the slug must be a 'host-free team draft-picks page slug.' This compensates for the bare schema. It stops short of giving format examples or a source for the slug, so not a 5.

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+resource: 'List every year, round and position in an NFL team's Sportskeeda draft history.' It also names its sibling and its role ('use the returned values with sportskeeda_draft_picks'), making its lookup purpose evident. Slightly short of 5 because it never explicitly frames itself as the 'options' prerequisite versus the main data tool, though that is strongly implied.

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 a clear usage flow: supply a host-free slug, then use the returned values with sportskeeda_draft_picks. It implies the when-to-use context (fetch valid filter values before calling the sibling). No explicit when-not or prerequisite caveats, so not a 5.

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