List updates

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

The description discloses that the list is user-specific ('your updates'), a scoping detail not present in the annotations. However, it omits pagination behavior, rate limits, and return structure. Annotations already cover read-only, idempotent, and non-destructive aspects, so this partial disclosure earns a mid-range score.

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?

The description is short and front-loaded with the primary purpose. The 'Level API endpoint: GET /v2/updates' sentence is somewhat cryptic and adds little operational value for an agent, but aside from that, there is no redundancy.

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?

The tool has no output schema, and the description does not mention default behavior like limit=20 or what an update object contains. However, the schema covers all filters and annotations establish safety, making it minimally viable for a straightforward list operation.

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?

All 6 parameters are fully described in the input schema (100% coverage), including filters and pagination cursors. The description adds no additional parameter-level meaning, so it falls at the baseline of 3 for high schema coverage.

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 description clearly states that the tool lists updates and returns the caller's updates. The resource (updates) is distinct from sibling list tools (devices, groups, tags), avoiding confusion. However, it is terse and largely restates the title without adding scope or filtering nuance.

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 guidance is given on when to use listUpdates versus showUpdate or other list tools. There are no alternatives, exclusions, or prerequisites mentioned, leaving the agent to infer usage purely from the resource name.

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