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

readOnlyHint=true already tells the agent this is a safe read. The description adds the underlying endpoint (GET /v1/assets/agents) and the surfaced fields (status, OS, client), but says nothing about pagination behavior, default ordering, or result size limits beyond what the schema's cursor/page_size descriptions already imply.

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 compact sentences with the resource description front-loaded and the API path appended as reference. Nothing is wasted or repeated.

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 six-parameter, all-optional read-only list tool with full schema coverage and no output schema, the description gives enough to call it correctly. A brief note on default result ordering or pagination expectations would close the remaining gap.

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 100%, and all six optional parameters are documented in the schema, including enum-ish status ids and pagination cursors. The description adds no parameter-level meaning beyond that, so baseline 3 is correct.

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 ('List agent (RMM managed device) assets') and clarifies what an 'agent asset' is, which implicitly separates it from gorelo_list_custom_assets, gorelo_get_agent_asset and gorelo_list_agent_pending_updates. It does not explicitly name any sibling, so it falls just short of a 5.

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?

Usage is only implied: an agent can infer it should call this to enumerate devices and apply the query/client/status/updated_since filters. There is no explicit statement of when to prefer this over gorelo_list_custom_assets or when to switch to gorelo_get_agent_asset for a single device.

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