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

Annotations already declare readOnlyHint=true and openWorldHint=true, so safety is covered; the description goes further with domain behavior: 25% fee-share lock (20% when the launching agent is referred) and the explicit warning that the buyback cron is not live, so empty buyback rows should not be read as failed fee-shares. That interpretation guidance is genuinely additive; only pagination behavior for the limit is unaddressed.

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 what is loaded, followed by the caveats. Dense but every clause carries real meaning; no filler or repetition of the name.

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?

With no output schema, the description does explain the return shape (launches, remit totals, buyback runs) and adds a key interpretation caveat, which is good. However, it omits any treatment of the limit parameter and any scoping/pagination context, leaving a gap for an agent that needs to page results.

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?

The single parameter (limit, 1-100) has 0% schema description coverage, so the description carries the full burden, yet it never mentions the parameter or its effect on result size. With coverage below 50% the description should compensate, and it does not.

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?

States a specific verb (Load) and resource (public proof tape) and enumerates the content: launches, remit totals, buyback runs. An agent knows what it retrieves, though it never distinguishes itself explicitly from close siblings like crew_list_launches or crew_status.

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?

Usage is only implied: a read-only 'proof tape' for accountability data. There is no statement of when to prefer this over crew_list_launches, crew_status, or crew_discover, and no prerequisites are given, so the agent must infer the routing.

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