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

Annotations already establish readOnlyHint=true, openWorldHint=false and destructiveHint=false, so safety is covered. The description usefully discloses severity semantics (required items block launch, warnings are advisory), which is genuine behavioral context beyond the annotations, but it says nothing about permissions, what entity the checklist applies to, or result format.

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 tight sentences with no filler, and the key constraint (required items block the launch) is front-loaded after a brief purpose statement.

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?

There is no output schema, so the description should carry more of the return-value burden. It explains the two severity tiers but omits pagination/shape, and the undocumented required 'id' parameter leaves an agent unable to call it correctly — a significant gap for a 1-param 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?

Schema description coverage is 0% for the single required 'id' parameter, and the description never mentions it. The critical ambiguity — whether 'id' is a campaign, domain, or user id — is left entirely to inference, so the description fails to compensate for the schema gap.

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 first sentence is a verbatim restatement of the title rather than a description of the operation, so the agent must rely on the tool name ('get_launch_checklist') to infer that it retrieves a checklist. The second sentence adds real meaning by defining what the returned items mean (required vs. warning), which lifts it above pure tautology, but the resource queried is never stated.

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?

No indication of when to call this versus launch_campaign or preview_campaign, nor any prerequisite (e.g., 'call before launch_campaign'). The description only characterizes the output, never the usage context.

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