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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered. The description adds real behavioral context beyond that: processing is transient, explicit user consent is a hard gate, and PHI/diagnosis/treatment content must not be submitted. It doesn't say what happens to the produced brief or how long it persists.

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 sentences, zero filler, front-loaded with the purpose before the consent constraint and the scope boundary. Each sentence carries distinct information (what it does, the consent gate, what is excluded).

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 no explanation, and the description covers purpose, consent, and privacy scope. The gaps are the undocumented 'detailsToBring' parameter and the relationship to the sibling render step, neither of which is addressed.

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 only 14% (just consentConfirmed), so the description carries most of the load; it does enumerate goals, changes, impacts, medicines and questions, which maps to five of seven parameters. However, 'detailsToBring' is never mentioned, and no format or granularity guidance is added beyond the field names. Baseline-plus given low coverage.

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 names a specific verb ('Structures') plus the target artifact ('appointment brief') and enumerates the input content types (goals, changes, impacts, medicines, questions). This is unambiguous about what the tool does. It does not distinguish itself from the sibling 'render_appointment_brief', so an agent must infer whether prepare feeds render.

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?

It states a clear precondition (explicit consent required for transient processing) and an explicit scope exclusion (PHI, diagnosis, treatment advice are out of scope), which tells the agent when not to use it. It stops short of naming an alternative or the follow-on sibling tool (render_appointment_brief), so routing to the next step is left to inference.

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