Annotations already declare readOnlyHint=true, idempotentHint=true and destructiveHint=false, covering the safety profile. The description adds only the raw endpoint path, contributing no extra behavioral context such as pagination behavior or filter interaction.
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?
One short sentence is technically economical, but here brevity reflects under-specification rather than tight writing. The single sentence earns its place only as a label, not as usable guidance.
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 an 8-parameter list tool with no output schema and a 25% schema coverage rate, the description should at least sketch filtering and pagination semantics. It omits all of that, leaving the agent under-informed on a non-trivial tool.
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?
There are 8 parameters with only 25% schema description coverage, so the description is expected to compensate — but it explains none of them (search, status, date range, documentType, externalId). Only the two ISO timestamps are documented in the schema itself.
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 clear verb+resource ('List customers') and names the underlying endpoint, so the basic operation is identifiable. However, with siblings like safefy_payment_get_customer, safefy_payment_create_customer and safefy_payment_update_customer, it offers no differentiation about scope or when this list is the right choice.
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 when-to-use guidance, no exclusions, and no mention of alternatives such as get_customer for a single record. An agent must infer usage purely from the name.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
