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

Annotations declare it is not read-only and not destructive, so the safety profile is covered. The description adds one genuinely non-annotated behavior: it "proposes one confirmation batch" rather than committing immediately. However, it says nothing about batch size limits, partial-failure handling, or what happens if an item fails validation — real gaps for a bulk mutation.

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 short sentences, front-loaded with the core action, then the classification rule, then the routing preference. Nothing is repeated from the schema and no sentence is filler.

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?

No output schema exists, so the description should indicate what the agent gets back — presumably a confirmation batch to approve, which it hints at but never describes structurally (accepted vs. rejected items, ordering). For a mutation tool with a rich nested schema it is adequate but leaves an agent guessing about results and limits.

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 top-level parameter, but it is a nested object array with many optional fields at 0% schema description coverage, so the description must carry meaning. It usefully explains the semantic mapping for the `type` enum (one-off task / recurring routine / decision), yet leaves frequency, weekdays, energy_required, time_hint, and estimated_minutes entirely unexplained in both schema and description.

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 (create many household items) plus the input shape (a list the user dumped), and explicitly contrasts with the sibling create_task. An agent can distinguish bulk creation from single-item creation without opening either schema.

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?

"Prefer this over many separate create_task calls" gives an explicit alternative and the condition that selects it. What's missing is the converse routing (use create_task for a single item) and any note about when items should be split into different types, but the intended usage is clear.

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