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

Annotations already declare readOnlyHint=true, idempotentHint=true, destructiveHint=false and openWorldHint=false, so the safety profile is covered structurally. The description adds nothing beyond that—no indication of what a checklist contains, how items are structured, or whether output is static or tailored.

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?

Five words is concise to the point of under-specification rather than efficiency. There is no structure, no front-loaded verb, and nothing that earns a sentence because no real content is present.

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 zero parameters, no nested objects, and no output schema, there is little surface area to document, so a terse description is closer to adequate than it would be for a complex tool. Still, an agent has no idea what the returned checklist looks like or how it is scoped to a relocation.

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 tool takes zero parameters and the schema is empty, which is the baseline-4 case. There is nothing for the description to disambiguate, though it also fails to explain how a parameterless call produces a relocation-specific checklist.

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?

"Relocation checklist planner" essentially restates the tool name (planning_relocation_checklist) with a synonym swap. It never states a verb like generate/create or what the output is, so the agent cannot distinguish it from siblings such as planning_packing_list or planning_travel_countdown beyond the word 'relocation'.

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?

The description gives no guidance on when to use this tool, no preconditions, and no mention of alternative planning tools for related tasks. The agent must infer everything from the name alone.

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