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

With no annotations, the description carries the full burden, and it does disclose meaningful behavioral facts: this is a mutation ('Set'), the caller must be the submitter or verified domain owner, and X-Agent-Key is required. It stops short of stating reversibility, what existing settings are overwritten, or side effects, which matters for a write tool with nested objects.

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?

Three short, front-loaded sentences with no filler; the core purpose leads and constraints follow. Efficient, though terse relative to the underlying complexity.

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?

This is a mutation tool with nested objects, no annotations, no output schema, and 0% schema coverage, so the description should do substantially more. It covers authorization but omits what fields are set, what happens on conflict, and the return shape, leaving key gaps for a complex write.

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 0%, so the description must compensate, but it only loosely references 'connect' and 'pricing' without explaining field meaning, the slug, or the enum values (auth, pricing.model). The nested connect/pricing objects are left entirely to the schema with no added semantic guidance.

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 names a specific verb ('Set') and resources ('how to connect to your launch and its pricing'), letting an agent distinguish it from read siblings like get_launch. It stops short of explicitly naming or contrasting with sibling tools, so it is clear but not fully differentiated.

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 provides authorization constraints ('Only for the submitter or verified domain owner') and a credential requirement, which implies the context of use. However, it gives no explicit when-to-use guidance or comparison against alternatives like get_launch, leaving usage partly inferred.

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