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

Annotations already declare readOnlyHint=true, destructiveHint=false and openWorldHint=false, covering the safety profile. The description adds useful context by disclosing what the payload contains (slug, name, kind, status, recent request counts) and clarifying that slug is the identifier pipelines and conditions reference, which is real value beyond the annotations. It says nothing about pagination or result volume, though.

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 tight sentence with zero filler, and the returned-field list is front-loaded after the verb+resource. The parenthetical about slug is justified because it explains why the field matters.

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?

With no output schema, the field enumeration is exactly the kind of information the description should supply, and it does. The main omission is any mention of the archived/all filter or result size, but for a one-parameter read-only list tool this is close to complete.

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% and the single 'status' parameter already documents the live/archived/all values with its default, so the schema carries param semantics. The description never mentions filtering, so it adds nothing here, but it does not need to given full coverage.

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 ('List the organization's agents') and enumerates the fields returned, so the agent knows this is a roster/enumeration tool rather than a detail fetch. It does not explicitly contrast with the sibling get_agent, but 'List' vs. 'get' is conventionally 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 guidance on when to use this over get_agent, create_agent, or list_agent_tool_access, and no mention that it supports an archived/all filter. The only selection-relevant detail (status defaults to live) lives entirely in the schema, not the description.

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