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

readOnlyHint=true already declares the safety profile, so the description's burden is lower. It adds genuinely new behavioral detail not in the schema — a 25-per-page cap — plus the underlying endpoint, but says nothing about ordering or what a comment contains.

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 short sentences, front-loaded with the page size and the user filter. The trailing raw endpoint path (GET /assets/<ASSET#>/comments.api) is marginal value but small enough not to hurt readability.

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?

With a fully described 3-parameter schema and no output schema, the definition is workable but thin. It never characterizes the returned comments (fields, ordering, how pagination terminates), which matters when there is no output schema to fall back on.

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 coverage is 100%, so all three parameters are already documented, including the 1-based page semantics and the created_by_id filter. The description's only added value is the 25-per-page figure, which is baseline-plus rather than a real semantic gain.

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 resource (comments) and scope (one item, optionally one user), which is enough to separate it from the sibling ezrentout_add_asset_comment and the broader list_* tools. It doesn't explicitly name a sibling or contrast with one, so it stops short of a 5.

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?

Usage is only implied: you need an asset number and may narrow to a single user. There is no explicit statement of when to use this versus ezrentout_get_asset_history or other per-asset reads, and no exclusions or prerequisites.

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