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

Annotations already declare readOnlyHint=true and openWorldHint=false, so the safety profile is covered. The description adds some behavioral context by specifying that the tool returns both latest state and change log, but it omits pagination behavior, whether the result is bounded by the limit parameter, and any permission requirements.

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?

A single front-loaded sentence with no filler or redundancy. It states the operation and object efficiently, making it easy for an agent to parse at a glance.

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 two-parameter read tool with no output schema and no parameter descriptions in the schema, the description is too thin. It never explains the limit parameter, does not clarify what a monitor is relative to the page-focused siblings, and provides no guidance on return size or pagination.

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 carry the semantic burden. It only indicates that an id identifies the monitor; the limit parameter, including its 1–50 range and meaning as a change-log count, is entirely undocumented.

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 states a specific verb (Read) and resource (latest state and change log of a monitor by id), so the tool's function is clear. However, it does not explicitly differentiate itself from the sibling tools extract_page and watch_page, leaving resource boundaries implicit rather than stated.

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 offers no when-to-use guidance, no exclusions, and no comparison to alternatives such as extract_page or watch_page. Usage is only implied by the verb and resource, which is insufficient for an agent choosing among three tools.

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