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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so the safety profile is covered structurally. The description adds genuinely useful context beyond that: the cursor is opaque, results paginate, and credential hashes are never returned — a meaningful disclosure for an inventory listing.

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 compact sentences with the core resource and scope front-loaded, followed by filtering/pagination, then a security caveat. Every sentence carries distinct information and nothing is padded.

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 read-only list tool with full schema coverage and no output schema, the description covers scope, filters, pagination and a notable return-value constraint. It could be slightly stronger by hinting at the response shape or noting the default row count, but nothing critical is missing.

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%, so the schema already documents kind, status, limit (with range and default) and cursor. The description only restates status/kind filtering and cursor pagination without adding format or interaction detail, so the baseline of 3 applies.

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 (List) and resource (registered devices) with a parenthetical enumeration of device kinds, so an agent immediately knows the scope. It does not, however, explicitly distinguish itself from neighbors like tascan_get_device or tascan_list_assets, leaving that inference to the agent.

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 names the two available filters and the pagination mechanism, which implies how to narrow results, but never states when to use this tool instead of tascan_get_device (single device) or tascan_list_assets. No exclusions or prerequisites are given, so usage is only implied.

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