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

Annotations already establish readOnly/idempotent/non-destructive/openWorld=false, so the safety bar is covered. The description adds genuinely useful behavior the annotations do not: amounts are bare numbers with no currency, and the agent must call get_organization_settings for currency_code before stating one. It omits return shape and pagination behavior, but that is partly covered by the schema.

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 front-loaded sentences; the core purpose and filters come first, and the currency warning is placed last without bloat. Every sentence carries information, though the filter enumeration slightly duplicates the schema.

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 a fully documented schema, full annotation coverage, and no output schema, this is nearly complete. The currency caveat addresses a real downstream pitfall, though the absence of any return-format note beyond the schema leaves a minor 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%, so all 8 parameters are self-documented (including auto-pagination defaults). The description's filter enumeration maps to those params but adds no syntax, format, or edge-case meaning beyond the schema, 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+resource ("List assets in your AssetLab account") and enumerates the supported filter dimensions. It is clearly distinguishable from get_asset, but it never differentiates itself from near-neighbors like list_infrastructure_assets or list_project_assets, so an agent must infer which asset collection applies.

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 filter list and the currency caveat imply when the tool is appropriate, and the pointer to get_organization_settings is actionable. However, there is no explicit when-to-use vs. list_infrastructure_assets/list_project_assets guidance and no statement of prerequisites or exclusions.

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