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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the underlying REST path (GET /clientapis/resourcemanagement/v1.0/form/{id}), which signals a thin API passthrough, but it says nothing about not-found behavior or what a form contains. With annotations carrying the behavioral load, a 3 is appropriate.

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?

One tightly written sentence with the operation and the id source front-loaded, followed by the endpoint. Nothing is redundant, though the raw REST path is of limited value to an agent selecting the tool.

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 is the only place an agent could learn what a form object contains, and it omits that entirely. For a simple single-parameter read this is a modest gap, but the return shape remains unknown before invocation.

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 100% and the id parameter already has a description and a pattern constraint, so the baseline would be 3. The description adds genuine meaning beyond the schema by naming safetychain_list_forms as the source of valid ids, discouraging fabricated identifiers.

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 and resource ('Get one form by id') and explicitly scopes the result to a single entity, which distinguishes it from safetychain_list_forms and the many other safetychain_get_* siblings that target different resources (capa, customer, equipment, record). An agent can pick this tool 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?

The parenthetical '(an id from safetychain_list_forms)' gives concrete guidance on how to obtain the required argument, which is the main usage question for a get-by-id tool. It stops short of stating exclusions (e.g., that it should not be used to enumerate forms or to fetch records), so it is not a full when/when-not statement.

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