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

Annotations already declare readOnlyHint=true, non-destructive, and closed-world, so the safety profile is covered. The description adds the domain context that this is the form a student fills when joining a plan, but says nothing about return shape or whether unpublished/toggled forms are included. With annotations carrying the behavioral load, this is an acceptable middle score.

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?

Two very short sentences with the resource defined first and the ID source second. Efficient, though the second sentence duplicates the schema field rather than adding information.

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?

There is no output schema, so the description should indicate what is returned, but it never clarifies whether the result is a form template, its fields, or a completed submission. For a read tool surrounded by near-identical siblings, that omission leaves a real gap.

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 100% and the single parameter already documents itself as "Id from list_subscriptions"; the description merely repeats that phrase. No added meaning beyond the schema, so baseline 3 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 identifies a specific resource (the anamnesis form tied to a subscription) and its domain role in joining a plan, so the agent knows what it fetches. It does not, however, distinguish this from the close siblings get_subscription_anamnesis_answers, get_anamnesis_form, or list_anamnesis_forms, leaving ambiguity about whether it returns form structure or submitted answers.

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 only guidance is where to obtain the ID ("Id from list_subscriptions"), which is a prerequisite, not a when-to-use rule. Nothing tells the agent when to pick this over get_subscription_anamnesis_answers or get_anamnesis_form, even though those siblings overlap heavily.

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