Approve Session Plan

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

No annotations are provided, so the description carries the full behavioral burden. It is an approval/mutation action but does not disclose what approval triggers, whether it is reversible, what permissions are required, or what happens if no plan exists. That is a significant gap for a state-changing 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?

A single front-loaded sentence with no filler. It is appropriately sized, though its brevity is partly a function of under-specification rather than deliberate tightness.

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?

An output schema exists so return values need not be explained, but the description still omits the essentials for a state-mutating approval tool: preconditions, side effects, and the role of '_meta'. With no annotations to lean on, the definition is not complete enough to call safely.

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 compensate and does not. session_id is self-evident, but the second parameter '_meta' is completely opaque in both schema and description, leaving half the surface undocumented.

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 ('Approve the generated plan for a session'), which is distinct from every sibling (none of which handle plan approval). It is clear what the tool does, though it never contrasts itself with the sibling set or explains what a 'plan' is in this session lifecycle.

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?

No when-to-use guidance, no prerequisites, and no mention of what state the session must be in before a plan can be approved. The 'single native MCP call' phrasing hints at efficiency but tells the agent nothing about selection or ordering relative to get_session/delete_session.

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