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

Annotations already declare readOnlyHint, idempotentHint, non-destructive and closed-world, so the safety profile is fully covered. The description adds genuine domain context that the rows carry target values and standings multipliers, but says nothing about result ordering, pagination behavior, or what an empty filter returns.

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 short sentences, front-loaded with the resource statement and free of filler. The brevity is efficient but tips into under-specification for a seven-parameter tool, so the terse structure is not fully earning 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?

With seven optional parameters, no schema descriptions, and no output schema, the description should carry most of the burden but covers roughly a quarter of the filter surface. An agent cannot tell how to page through results or how the three ID filters narrow the rows.

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%, so the description must compensate, yet it only names two of seven parameters (sport, stat). The four identifier filters (pickable_id, pick_group_id, pickable_market_id) and the limit/offset pagination controls are never explained, and the phrasing implies sport/stat are the only available filters.

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 identifies the resource ("Stored Pick6 market rows with target values and standings multipliers") and a retrieval intent, but uses no verb and never states it returns a list. Against sibling get_pick6_history the distinction is unclear, since both concern Pick6 data and no differentiating scope is given.

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?

No when-to-use guidance is provided and no alternative is named, even though get_pick6_history sits in the sibling list and likely overlaps. The agent must infer selection criteria from the name alone.

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