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

With no annotations provided, the description must carry the full burden of behavioral transparency, but it contains no verb and describes no action, side effect, return value, or read-only nature. 'The criteria and any filters...' is a static label, not a description of what happens when the tool is invoked.

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 concise with no redundant filler, but it is under-specified and grammatically incomplete. It is a short noun phrase rather than a clear, front-loaded operational statement, so it does not fully earn 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?

There is no output schema and no annotations, so the description alone must explain what an agent will receive or learn by calling the tool. It only identifies the subject area and does not describe the expected outcome, response format, or relationship to sibling tools, leaving a significant gap.

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?

The tool has zero parameters and the schema already reflects this completely. There is no parameter semantics for the description to add, so the baseline of 4 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?

The description is a noun phrase rather than a statement of what the tool does, and it largely restates the name and title. It adds domain context about 'Six routes to machine-readable bank transactions' but never says whether the tool lists, compares, explains, or returns criteria and filters.

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 guidance about when to use this tool instead of siblings like compare_options, compare_table, or enquiry_describe. No conditions, exclusions, or alternative tool names are mentioned, so the agent must infer usage from the tool name alone.

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