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

Annotations already declare this is a read-only, idempotent, non-destructive operation, so the description does not need to restate safety traits. The description adds useful behavioral context by describing the returned disclosure log contents: what each company committed, when, the source, and subsequent stock performance. It still does not mention pagination behavior, but the schema covers limit and cursor.

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?

The description is two sentences and front-loads the core purpose before explaining the portfolio slice. The second sentence is somewhat redundant because the portfolio enum and values are already fully described in the schema, but the overall text remains efficient and easy to scan.

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 read-only data-retrieval tool with a fully described six-parameter schema and no output schema, the description is largely complete: it explains what the disclosure log contains and how to select a portfolio slice. The main missing context is how this tool relates to the adjacent sponsors holdings and performance 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 100%, so the schema already documents all six parameters, including the portfolio enum. The description highlights the portfolio parameter and repeats its allowed values, but it does not add semantics beyond the schema for search, sorting, pagination, or date/price fields. Baseline 3 is appropriate when the schema does the heavy lifting.

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 clearly states a specific verb and resource: retrieving a disclosure log of public companies backing Trump Accounts and the White House Ballroom, including commitments, dates, source, and stock performance. It is distinguishable in substance, but it does not explicitly differentiate itself from sibling tools such as get_trump_sponsors_holdings and get_trump_sponsors_performance.

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 explains how to use the portfolio parameter to select 'all', 'trump-accounts', or 'ballroom', but it gives no guidance on when to use this tool versus the related sponsors holdings and performance siblings. The intended use case is implied by 'disclosure log' and 'what each company committed', but there are no explicit alternatives or exclusions.

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