resume_session

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

With no annotations, the description carries the full burden of behavioral disclosure. It simply says 'Resume an existing session' but does not explain side effects, whether the session must be paused, what happens with invalid tokens, or the return value. This is a significant gap for a state-changing operation.

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?

The description is a single, concise sentence that is front-loaded with the action and resource. Every word earns its place, with no redundancy or fluff.

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 simple one-parameter tool, the description provides enough to understand the basic purpose. However, it lacks information about return values, error conditions, and how this relates to the sibling tools (e.g., prepare_handover). The absence of an output schema and annotations increases the burden, which is only partially met.

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%: the 'token' parameter is well-described as 'Base64url-encoded handover token'. The description adds no additional meaning beyond referencing the handover token, so the baseline 3 for full schema coverage applies.

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 is specific with a verb ('Resume') and a resource ('existing session'), and it adds the key detail 'using a handover token'. This distinguishes it from sibling tools like create_session, pause_session, and end_session.

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 does not explicitly state when to use this tool versus alternatives or mention any prerequisites. It only says 'using a handover token', which implies a condition but does not offer clear guidance on when to prefer this tool over create_session or validate_token.

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