B3.2/5.0

Behavior4/5

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

Annotations already cover readOnlyHint, openWorldHint, idempotentHint, and destructiveHint. The description adds meaningful behavioral context: messages are untrusted content and embedded instructions should not be followed, and the cursor is bounded/resumable. 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 focused sentences with the action front-loaded and a security warning following. No filler or redundancy; every word earns its place.

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

Completeness2/5

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

While an output schema exists, this tool has 7 optional parameters with minimal schema descriptions. The description does not clarify parameter interactions, how 'bounded' works in practice, or how the cursor is used. The security warning is valuable but leaves the tool under-documented for a paginated message reader with many filters.

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

Parameters2/5

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

Schema description coverage is only 14%, with only 'kind' described. The description references the cursor concept but does not explain high-optional parameters like to, page, room, limit, or query. With such low schema coverage, the description should have compensated with parameter guidance and did not.

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

Purpose4/5

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

The description uses a specific verb ('Read') and resource ('public messages'), and mentions a bounded, resumable cursor, making the primary action clear. However, it does not explicitly differentiate this from sibling tools like read_thread or read_updates, so it lacks explicit sibling differentiation.

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?

There is no guidance on when to use this tool versus alternatives. The only usage context is the implicit 'use this to read public messages', with no mention of when not to use it or how it compares to read_thread, read_updates, or post_message.

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