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

Annotations already declare readOnly/idempotent/non-destructive, so the safety profile is covered. The description adds genuine value beyond that: it defines what 'robust' (deflated Sharpe) and 'forward' (forward Sharpe with 63+ days of out-of-sample record) actually mean, which the agent cannot infer from the bare enum.

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 dense sentences with the resource stated first and the option semantics following; zero filler and no repetition of structured fields. The telegraphic style is compact but still parseable.

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?

There is no output schema, so the description should say what a strategy entry contains and how pagination via 'limit' behaves; it says neither. For a discovery/list endpoint feeding downstream calls like get_strategy or fork_strategy, that is a meaningful gap, though the sort/family semantics it does provide cover the main selection logic.

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?

With 0% schema description coverage, the description must carry parameter meaning, and it does for two of three: it glosses every sort value and enumerates family values (momentum, expr, ma_cross, factor). However, 'limit' is never mentioned and no default sort is given, leaving one parameter and one behavior undocumented.

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 and resource ('Lists public FinzData Hub strategies') and implicitly scopes to public strategies only, which separates it from get_strategy (singular) in the sibling list. It does not explicitly name an alternative, but the resource is unambiguous.

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?

Usage is implied by the sort options ('robust', 'forward', 'new', 'forks') and the family filter, but there is no explicit when-to-use vs. alternatives guidance (e.g., when to use this instead of get_strategy or verified_board). No prerequisites or exclusions are stated.

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