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

Annotations already declare readOnlyHint, idempotentHint, destructiveHint=false and openWorldHint=false, so safety is covered. The description adds genuinely useful behavioral context beyond that: assessments are point-in-time snapshots, scores are 0-100 with named bands, and currency must be resolved via get_organization_settings before any amount is stated.

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 sentences, front-loaded with purpose, then filters, then the interpretive and cross-tool notes. No filler and nothing repeated from the schema; every sentence carries information an agent would otherwise have to guess.

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 9-parameter read-only list tool with no output schema, the description is nearly sufficient: purpose, filters, score semantics and the currency prerequisite are all present. It omits result ordering and any note on default result volume, minor gaps given annotations already establish the safe-read profile.

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 coverage is 100%, so the baseline is 3, but the description adds real meaning on top of the raw fields: the 85+ Excellent / 70-84 Good / 55-69 Fair / 40-54 Poor / below 40 Critical scale for condition_min and condition_max, and the bare-number currency convention. That is interpretation the schema does not provide.

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 with scope: 'List point-in-time condition assessments recorded against assets.' The plural 'List' plus 'point-in-time' framing cleanly separates it from the singular get_asset_condition_assessment and from create/update/delete siblings without needing to name them.

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 enumerates the filter dimensions (asset, assessor, method, condition score range, assessment date range), which tells the agent when this tool applies. It does not explicitly say when this is preferable to get_asset_condition_assessment for a single record, so it stops short of full routing guidance.

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