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

Annotations declare readOnlyHint=false, idempotentHint=false, and destructiveHint=false, so the mutation/safety profile is partly covered. The description adds real value beyond that by disclosing the return value ('Returns the fresh intake state') and the dependency on next_action. It does not warn about re-invocation behavior despite idempotentHint=false, which keeps it from a 5.

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?

Three short sentences, each doing work: the action, the invocation gate, and the return value, in that order. No filler.

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 mutation tool with no output schema, the description covers what it does, when it is legal to call, and what comes back. The remaining gap is idempotency/repeat-call behavior given idempotentHint=false, which an agent would benefit from knowing.

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 url, access_token, and api_base_url. The description adds no syntax or format detail for any of the four parameters, so it neither compensates for the uncovered session_id nor improves on the schema.

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 ('Record the applicant's consent to processing') and distinguishes itself from siblings like submit_intake and save_intake_draft by scoping to the consent step. An agent can identify the operation without opening the schema.

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 an explicit gating condition ('when the intake state's next_action is consent') and a precondition for invoking it ('only after the applicant has agreed to the notice in next_action.notice'). This is exactly the when-to-use guidance an agent needs to avoid firing it prematurely.

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