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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds value beyond that by stating the read-scope requirement and by disclosing the returned fields (status, reason, reply counts), which is meaningful behavioral context for a read tool.

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?

One sentence, front-loaded with the core action and immediately followed by the enumerated outcomes and the scope requirement. No filler or redundancy.

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 usefully compensates by naming the status values and the accompanying reason and reply counts. It is nearly complete for a simple single-parameter read tool, though it does not say what happens for an invalid or unknown conversation ID.

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?

There is a single parameter with 100% schema description coverage, so the schema already carries the semantics and the baseline is 4. The description adds nothing parameter-specific, but nothing is missing either.

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 names a specific verb and resource ('get the responder's status for a single conversation') and enumerates the possible outcomes (active, paused, handed off, never seen), which makes the tool's scope unambiguous. It does not explicitly contrast itself with siblings like get_conversation or get_responder, so it falls 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 by the phrase 'for a single conversation' and the read-scope note; there is no explicit statement of when to prefer this over get_conversation or get_responder, nor any exclusion guidance. Adequate but leaves the agent to infer the selection criteria.

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