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 real context beyond that — it discloses what the payload contains (title, questions/pages, identifier types) and names the underlying endpoint GET /organizations/{org}/forms/{id}.json — but says nothing about failure modes or behavior when the form or version does not exist.

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 tight sentences, front-loaded with the resource definition and closing with the endpoint. Every clause carries information; the fragmentary style is dense rather than padded, though the trailing URL is the least essential element for an agent that cannot call it directly.

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?

With no output schema, the description must describe the return value, and it does so at a useful level of abstraction: title, questions/pages, identifiers and their types, plus the key insight that those identifiers are the keys used in submissions and dispatch payloads. That is enough to call the tool correctly and to use its result downstream, though deeper shape detail is absent.

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%, so both parameters are already documented, including the default-latest behavior of version and the pointer to list_forms for form_id. The description's 'Optionally a specific version' restates the optionality already encoded in the schema rather than adding format or constraint detail, so the baseline of 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?

States a specific resource and scope: a single form's definition, including its title, pages/questions, and the identifiers and their types. The 'One form's definition' framing contrasts cleanly with the list_forms sibling without needing to name it, and the parenthetical explaining that identifiers are the keys inside submissions and dispatch payloads pins down the meaning of the returned content.

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 description implies usage (fetch a form, optionally at a specific version) but never states when to prefer this over devicemagic_list_forms or the other get_* siblings. There are no exclusions, prerequisites, or error conditions mentioned, so the agent must infer the routing decision from the name alone.

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