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

Annotations already cover the read-only, idempotent, non-destructive profile, so the description adds real value beyond them: results are 'bounded', account numbers are masked to suffixes, and no bank connection or funds movement occurs. It does not address pagination limits or total-count behavior, which keeps it short of a 5.

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 compact sentences with no filler, and the most decision-relevant fact (what is returned, with masked suffixes) is front-loaded before the safety caveat.

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 simple read-only list tool with rich annotations and no output schema, the description is nearly sufficient: it says what comes back (summaries, verification status, masked suffixes) and what it will not do. The missing piece is how paging works and whether a total is returned.

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. 'Bounded' hints at the limit cap, but the single nested 'input' parameter with limit/offset is never explained — no defaults, no max page size, no offset semantics. The JSON schema's own min/max/default values carry most of the load.

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: read saved statement summaries plus verification status. Its scope ('bounded', 'masked account suffixes only') is clear, though it never distinguishes itself from close siblings such as list_vendor_statement_summaries or list_rate_confirmation_summaries.

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 explicit when-to-use or when-not-to-use statement and no named alternative. The clause 'No bank connection or money movement' does implicitly tell the agent this is a read of already-saved data rather than a live bank fetch, which is useful but leaves sibling selection to inference.

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