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

Annotations already declare readOnlyHint=true, destructiveHint=false, openWorldHint=false, so safety is covered. The description adds real behavioral context beyond that: the domain serving check answers whether the form is live, the delivery settings reveal whether the form will accept responses, and utmSource tagging propagates across every link and snippet. It does not mention auth requirements or rate limits, so it stops short of a 5.

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?

Front-loaded with the returned artifacts, then the utmSource behavior, then the routing to update_form_settings. Dense but every clause carries information; the only mild cost is a long first sentence enumerating outputs.

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?

For a read-only 4-parameter tool with an output schema, the description supplies exactly the missing context: what the payload is for, how a parameter changes the payload, and which sibling performs the write. Nothing an agent needs before calling 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 coverage is 100%, so baseline is 3, but the description adds cross-parameter meaning: passing utmSource tags 'every link and snippet' for one channel, which goes beyond the per-parameter schema text. The iframe and popup parameters are left to the schema, which documents them well.

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 (get) and resource (form share info) and enumerates exactly what comes back: public answer link per language, custom domain and serving status, embed snippets in three modes, and current delivery settings. An agent can distinguish this from get_form (definition) or get_form_stats without inspecting any 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?

Explicitly names the use cases ('give me the link / the embed code', sanity-check a launch) and routes the mutation case to the sibling: 'change the switches with update_form_settings.' Both when-to-use and when-to-use-something-else are covered.

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