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

Annotations already flag destructiveHint=true and readOnlyHint=false, so the safety profile is known. The description adds real value with the running-launch restriction, but is silent on consequences beyond annotations: whether associated content/analytics are removed, irreversibility, or how a rejected running-launch deletion is surfaced.

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?

One compact sentence with the core action front-loaded and the caveat immediately attached. No filler, though the parenthetical constraint could be phrased more distinctly as a condition.

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 one-parameter delete with full schema coverage and destructive annotations, the definition covers the essentials. It leaves out side effects of deletion and the failure mode for running launches, which an agent would want before calling a destructive tool.

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?

Single required 'id' parameter with 100% schema description coverage ('launch ID', UUID format), so the schema carries the semantics. The description adds no extra meaning about where the ID comes from or how to resolve it, which is acceptable at baseline.

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 and resource ('delete a launch') with a scope constraint in parentheses, so the operation is unambiguous. It doesn't name sibling alternatives, but the verb alone distinguishes it from create_launch/get_launch/update_launch.

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?

Gives an explicit exclusion — running launches cannot be deleted — which is useful precondition guidance. It stops short of naming what to do instead (e.g., a status/cancel tool) or stating any other prerequisites such as permissions.

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