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

With no annotations, the description carries the full behavioral burden. It usefully discloses the sort order and the conditional 'budget block when that agent has a spend cap', but says nothing about pagination behavior, auth/permission requirements, or that this is a read-only operation beyond the verb 'List'.

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 tight sentences with the core action front-loaded and zero filler. The parenthetical '(the manager leads)' is slightly cryptic but earns its place by explaining the ordering semantics.

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?

An output schema exists, so return values needn't be described, and 75% of params are schema-documented. The description usefully adds the ordering and conditional budget-block behavior; the main gap is that a no-annotation read/list tool leaves pagination and safety characteristics implicit.

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 75% (kind, cursor, status documented; limit bare), and the description adds no parameter-level meaning of its own. It only describes row content, so the schema does essentially all the work — a baseline 3 is appropriate.

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 this org's agent records') and adds the ordering rule (oldest first, manager leads), so an agent knows exactly what the operation returns. It does not explicitly distinguish itself from siblings like agent_get or agent_routine_list, but the verb+resource pair is unambiguous.

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?

There is no when-to-use guidance, no prerequisites, and no mention of alternatives such as agent_get for a single record. The only usage-adjacent signal ('archived records are listed only when asked') lives in the schema's status param, not the description.

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