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

Annotations already declare the write/idempotent/open-world profile, and the description usefully adds that the AI resumes 'from the next message' rather than retroactively. But it does not explain what 'destructive' entails here, whether in-flight handoff state is lost, or any permission requirements, leaving meaningful behavioral gaps for a destructive-marked mutation.

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 zero filler; the action and the resulting behavior are packed into one clause each, with no redundancy against the title.

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 one required param, full schema coverage, no output schema, and annotations covering the safety profile, the description is nearly complete for invoking the tool correctly. Only the semantics of the destructive flag and any handoff side effects remain unexplained.

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 documents session_id. The description adds no syntax or format guidance beyond what the schema supplies, making the baseline 3 appropriate.

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+resource: handing a taken-over conversation back to the AI. It is clearly the inverse of the sibling take_over_conversation, but the description never names that sibling, so the differentiation is implied rather than explicit.

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 phrase 'a taken-over conversation' implies this is used after take_over_conversation, giving implied usage context. However, no explicit when-to-use, prerequisites, or named alternatives (e.g., send_agent_reply vs release) are provided.

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