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

With no annotations provided, the description carries the full burden. It discloses that the application is 'recorded' (a persistent side effect) and that 'our founder reviews every application and follows up by email' (a human workflow). This goes beyond the schema by explaining post-submission behavior, though it does not mention confirmation responses, reversibility, or authentication requirements.

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, front-loaded with the primary purpose, then additional behavioral detail. Every sentence earns its place without redundancy or fluff. Excellent structure.

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?

Given the tool's simple nature, the description adequately covers what happens (records application, founder review, email follow-up) and what is included. No output schema exists, so not detailing return values is acceptable. Minor gaps: no explicit mention that this is a write/creation action (though 'records' implies it) and no mention of expected response to the user.

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 the baseline is 3. The description adds a small amount of extra meaning by calling 'website' a 'host' and indicating 'message' provides context for follow-up, but it mostly restates the schema fields without significantly deeper semantics.

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 opens with 'Apply to become a CreationLoop design partner,' which is a specific verb (apply) and resource (design partner application). It clearly distinguishes itself from the read-only sibling tools (get_company_overview, get_faq, etc.) by being the submission/action tool.

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 gives clear context for when to use (applying to become a design partner) and describes the follow-up process. It does not explicitly name alternatives or state when not to use it, but the contrast with sibling get-tools is implicit through naming and purpose. A slight gap is the lack of an explicit 'use this instead of...' statement.

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