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

Annotations only state readOnlyHint:false and destructiveHint:false, leaving behavioral disclosure to the description. The description adds valuable context: 'requires view access' (permission requirement), 'threads are one level deep' (structural constraint), and 'a thread already marked complete still accepts replies and stays complete' (a non-obvious behavior). No contradiction with annotations.

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?

Three concise sentences with no filler. The primary purpose is front-loaded ('Reply to a comment thread'), followed by essential constraints and behavioral quirks. Every sentence earns 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?

For a low-complexity tool with three flat parameters and no output schema, the description covers the core purpose, a critical parameter constraint, and a behavioral edge case. It does not describe body or artifactId explicitly, but these are reasonably inferable from context. Overall adequate for an agent to call it correctly.

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 explain parameters. It does clarify that commentId must be a thread root, which is useful. However, body and artifactId are left entirely to inference (body is likely the reply text, artifactId likely the dashboard identifier). Given the 0% coverage, the description only partially compensates.

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 opens with a specific verb and resource: 'Reply to a comment thread on a Duvo Pulse dashboard.' This clearly distinguishes it from sibling tools like createPulseDashboardComment (which creates a new thread) and sendPulseDashboardMessage (for dashboard messages). It also notes the one-level-deep thread structure, reinforcing that this is strictly a reply operation.

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 makes it clear this is for replying to an existing thread, which implies when to use it. However, it does not explicitly name alternatives (e.g., 'Use createPulseDashboardComment for new threads') or state when not to use it. The constraint on commentId being a thread root provides practical guidance but not tool-selection guidance.

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