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

The description adds meaningful behavioral context beyond the annotations: it discloses that the action is an external submission to Seamgrin and mandates an ethical consent gate before calling. This complements the annotations (readOnlyHint=false, destructiveHint=false) without contradicting them.

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?

Two sentences with zero waste: the first states the action and purpose, the second front-loads the critical consent gate. Every clause earns its place.

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, consent-gated submission with an output schema and safety-related annotations already present, the description covers everything an agent needs: what the tool does, who it is for, and the precondition for calling. No meaningful 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 description coverage is 100%, and both parameters are already well documented in the schema: email is 'the user explicitly approved sharing' and confirmed 'must be true only after the user explicitly approves submission.' The description re-emphasizes the consent requirement but adds no parameter-level detail beyond what the schema provides, 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?

The description states a specific verb ('Submit') and resource ('an email for someone who wants clothing alterations from Seamgrin'), making the tool's function immediately clear. It is also readily distinguishable from siblings such as apply_for_tailor_training and register_experienced_tailor_interest, which target tailors rather than customers.

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 provides an explicit invocation precondition: 'Call only after the user explicitly confirms that their email may be sent to Seamgrin.' This is clear context for when the tool may be used, though it does not explicitly contrast the tool with alternatives. Given that the siblings serve obviously different purposes, no exclusion is strictly necessary.

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