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

Annotations already declare readOnly, idempotent, non-destructive, and closed-world behavior, so the safety profile is covered. The description adds meaningful traits beyond that: picks carry 'locked spreads/prices' (a frozen snapshot) plus timestamps, status, and source URLs, which is valuable since there is no output schema. It does not mention auth or gating for free vs. member access.

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 retrieval action and payload contents, with zero padding. The trailing 'Filter by market if desired' is the weakest sentence and mildly duplicates the schema, keeping it from a 5.

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 no output schema, the description responsibly enumerates the returned fields (spreads/prices, timestamps, status, source URLs), and annotations cover safety. Remaining gaps—what 'locked' means operationally and whether picks refresh—are minor for a read-only retrieval tool.

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 100%, so week, market, and season are fully documented with defaults and enum values in the schema. The description only alludes to market filtering and adds no format details or default behavior beyond what the schema states, so baseline 3 applies.

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 ('Retrieve') plus resource ('Jevan's weekly free ATS, moneyline, and Over/Under picks') and enumerates the payload fields. The word 'free' implicitly separates it from the sibling get_member_weekly_picks, but no sibling is named explicitly, so it stops short of a 5.

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?

The description offers only 'Filter by market if desired,' which is parameter behavior rather than usage guidance. It gives no when-to-use context, no conditions selecting it over get_member_weekly_picks or get_member_pick_context, and no exclusions.

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