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

The annotations already declare it is not read-only, not destructive, not idempotent, and open-world; the description adds substantial context beyond that. It discloses that attempts reset, the webhook is sent to the form's current URL, it is signed with the current secret, the same submissionId is reused for receiver deduplication, and only owners can call it.

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?

The description is dense but front-loaded with the core action and state change: resend from the start with attempts reset. Every clause carries useful information about targeting, signing, deduplication, usage condition, authorization, and result verification.

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 simple two-parameter mutation with full schema coverage and no output schema, the description supplies everything needed: when to use it, what state changes, how the target and signing are determined, who can call it, and how to verify the outcome. No critical behavioral or contextual gap remains.

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 both id and submissionId are already documented in the schema. The description adds useful semantic context around submissionId by explaining that the same submissionId is reused so receivers can dedupe, and it points to list_form_submissions as the source for that value.

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 states a specific verb and resource: resend a submission's webhook from the start with attempts reset. It also distinguishes the operation from sibling tools like list_form_submissions and list_form_webhooks by explaining that it targets an existing submission's webhook delivery.

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?

It explicitly says to use this for a FAILED or stuck delivery after fixing the receiver or URL, which is a clear when-to-use condition. It also names list_form_submissions({ submissionId }) as the way to check the result and states the ownership prerequisite.

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