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 genuinely useful cross-tool context: it notes the response carries "the revision update_form and set_form_status need", which tells the agent this call is a prerequisite for those mutations — something not derivable from the schema. It does not discuss failure behavior for unknown form_id or the size/shape of the payload.

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?

It is a single compact sentence with no filler, and the essential head ("One form's settings") is front-loaded. However, it is an unpunctuated comma-list of ten items that is harder to scan than a short prose sentence plus a few grouped clauses would be, and the parenthetical targetFormId mixes schema-level detail into prose.

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 readOnly annotations and a full output schema in place, the description only needs to establish scope and any non-obvious dependencies — and it does flag the update_form/set_form_status revision dependency. Only the lack of a stated verb and of sibling routing keeps it from being fully complete.

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 single form_id parameter is documented there as "The form's id, as list_forms returns it." The description adds nothing about the parameter itself (no format, prefix, or ID-provenance detail beyond what the schema says), 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 enumerates exactly what a caller gets back from a single form: fields, allowed websites, success message/redirect, anti-spam, alerts, sheet link, targetFormId, Record Fetch state, and revision id. That is a specific, distinctive resource scope, though it never states a verb ("retrieve"/"read") and never contrasts itself with list_forms or get_form_embed_code, so the sibling separation is inferred from "One form's" only.

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?

There is no explicit when-to-use or when-not-to-use guidance and no mention of alternatives such as list_forms for enumeration or get_form_embed_code for the embed snippet. The reader must infer from the resource scope alone that this is the read-one-by-id call.

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