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

With no annotations, the description carries the full burden and does it well: it flags that approving can change the live store, that the first call is side-effect free and returns a preview plus a confirmToken, that the token is valid 10 minutes and single-use, and that an "approve" permission scope is required. These are exactly the mutation-safety facts an agent cannot get from the schema.

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 and its blast radius ("Approving can change the live store"), then the two-call protocol, then the safety rules, then the permission requirement. Every sentence carries an instruction the agent needs; nothing is padding despite the length.

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 four-parameter, no-output-schema mutation tool, everything needed to call it correctly is present: id provenance, the two-step confirmToken handshake, the human-approval requirement, the batch prohibition, and the auth scope. No output schema exists, and the description already tells the agent what the first call returns.

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 75%, so the schema already documents id, api_key, and confirmToken. The description still adds real meaning beyond it: confirmToken must be the one from the preview, sent on the second call along with the same arguments. It says nothing extra about api_key, which the schema already handles, so this is above baseline without being exhaustive.

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 pair (approve or reject) against a precisely scoped resource: exactly ONE pending SeoAiX recommendation, for the user's own store. It also names the sibling that supplies the ids (list_pending_approvals), so the agent can distinguish it from every other sibling in the list.

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?

Gives explicit when-to-use (after picking one id from list_pending_approvals), explicit how (two calls, first without confirmToken), and explicit exclusions (never confirm on your own judgement, never loop over many items). The human-approval gate and the permission prerequisite are both stated as conditions, not left to inference.

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