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

The description explicitly asserts 'the call is idempotent', but the annotations declare idempotentHint=false. That is a direct contradiction on a declared behavioral trait, which per the rubric forces a 1 even though the description also usefully adds the view-access requirement and the response shape (resolved_at/resolved_by).

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?

Front-loaded with the action, dense but mostly waste-free, and it packs access requirements and return behavior into a compact statement. The single long sentence is slightly overloaded with semicolon clauses but 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?

With no output schema, the description helpfully characterizes the response (thread with resolved_at/resolved_by set or cleared) and states the access requirement. It is largely complete for a 3-parameter mutation, aside from the untrusted idempotency claim.

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 parameter meaning. It explains the semantics of `resolved` ('Pass the target state in `resolved`') but says nothing about `artifactId` or `commentId` beyond their UUID types in the schema, leaving half the intent to inference.

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 verb ('Mark ... complete') plus the inverse ('or reopen it') applied to a precisely named resource ('Duvo Pulse dashboard comment thread'). An agent can immediately distinguish this from sibling comment tools like createPulseDashboardComment or deletePulseDashboardComment.

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?

Covers both directions of use (complete vs. reopen) and states the access prerequisite ('requires view access'). It does not name an alternative tool or an explicit when-not-to-use condition, which keeps it short of a 5, but the usage context is clear.

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