B3.4/5.0

Behavior4/5

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

Annotations already cover safety (read-only, idempotent, non-destructive). The description adds behavioral context: 'Paid source-first' suggests source prioritization, and 'Returns every matching official document with complete cleaned text, source URL, hash and activity status' discloses the return payload details. This goes beyond the annotations without contradicting them.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two sentences with no filler. The first sentence states scope and source priority; the second details the return contents. Every word earns its place, and key information is front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description provides return fields and a full-result guarantee, but omits parameter details, output schema (none exists), and any usage context such as pagination or prerequisites. For a simple 2-parameter read tool with strong annotations, it is adequate but has notable gaps in parameter semantics and usage guidance.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters1/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%. The description does not mention either parameter (bank_code or activity_status) or their meanings. It only hints at 'one supported bank' but fails to explain how to specify it or what activity_status controls. There is no compensation for the low schema coverage.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly identifies the tool's action ('query') and resource ('official bank offer documents'). It distinguishes from sibling tool 'list_supported_banks' by specifying it operates on a single supported bank. The mention of returning 'every matching official document' adds precision.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description gives no explicit guidance on when to use this tool versus alternatives like list_supported_banks. It implies a prerequisite (a specific bank) but does not state scenarios or exclusions. No when-not-to-use or alternative references are provided.

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