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

Annotations already declare readOnlyHint=true and destructiveHint=false, so the safety profile is covered. The description adds the returned attribute set, which is genuinely useful given there is no output schema, but it says nothing about pagination, result caps, or permission scoping for the org-wide listing.

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?

A single front-loaded sentence with no filler; the parenthetical clarifying what a slug is for earns its place by adding domain meaning.

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 zero-required-parameter list tool with full schema coverage, the description is close to sufficient, and it usefully substitutes for the absent output schema by naming the returned fields. It stops short of covering pagination or org-wide permission constraints.

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?

Only one parameter, and schema description coverage is 100% — the status enum values (live/archived/all) and the default are fully documented in the schema. The description adds no syntax or format detail beyond that, so baseline 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 and resource ("List the organization's agents") and enumerates the attributes returned, so the agent knows this is a collection read rather than a single-agent fetch. It does not explicitly contrast itself with the singular get_agent sibling, which keeps it out of the top band.

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?

Usage is only implied: the parenthetical about slug hints at how agents are referenced elsewhere, and the schema's status parameter hints at the archive workflow. There is no explicit statement of when to use this instead of get_agent, list_members, or the archive/restore tools.

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