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

Annotations already declare readOnlyHint=true and openWorldHint=true, covering the safety profile. The only behavioral signal the description adds is the word 'public', implying no authentication, which is thin. It does not say what the identifiers represent or how they relate to the returned payload.

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?

It is a single short, front-loaded sentence with no wasted words, which is structurally fine, but the brevity comes at the cost of substance—it reads as an under-specified fragment rather than a purposeful statement.

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 one-parameter tool with an output schema and annotations, the structured fields carry return format and safety, but the description still leaves the core question unanswered: what this context tool provides and when to call it instead of the sibling event/league tools.

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% for the single required event_id, so the description must compensate and does not. It never states the expected format of event_id or where such an identifier originates (e.g., from draftkings_league_events).

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 is a noun phrase ('public sport, league, and event navigation identifiers') with no verb, so it never states what the tool actually does—fetch, list, resolve? It also fails to distinguish itself from close siblings like draftkings_event, draftkings_event_markets, and draftkings_leagues, all of which touch the same sport/league/event domain.

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?

There is no when-to-use guidance, no condition that selects this tool over its many draftkings_* siblings, and no prerequisites. The agent is given nothing to route on.

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