Preflight launch

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

No annotations provided, so description fully carries burden. It details the checks performed and mentions return format (pass/fail with remediation hints). Does not explicitly state read-only nature, but checks are non-destructive.

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 sentences, front-loaded with key timing instruction, each sentence adds unique value. No superfluous content.

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?

Single required parameter, no output schema needed. Description covers purpose, checks, and output format sufficiently for an agent to invoke correctly.

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?

Only one parameter (plan_id) with 100% schema coverage. Schema already describes it as 'Launch plan id (launch_*)', and description adds no additional parameter details beyond that.

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?

Description clearly states it verifies stack launchability before step 1, listing specific checks (provider tokens, mappings, Stripe mode, Namecheap IP). This distinguishes it from sibling tools like verify_launch which may be more comprehensive.

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 says 'Run before step 1' and 'Run before any money is spent', indicating clear context for use. Does not explicitly state when not to use, but the context implies it's a prerequisite check.

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