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

With no output schema, the field list (id, handle, name, status, visibility, listed) plus the status enum (draft | live) is genuinely useful disclosure beyond the structured fields. The auth requirement is also stated. However, it leaves the read/write nature ambiguous against a readOnlyHint=false annotation on what is clearly a listing call, and says nothing about pagination or filtering limits.

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 compact sentences with the auth prerequisite front-loaded and no filler. Efficient, though the second sentence is a comma-heavy field dump rather than structured.

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 parameterless read with no annotations worth leaning on and no output schema, the description compensates by enumerating the expected return fields. Only the read-only vs. mutating semantics and any result-size behavior remain unaddressed.

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?

The tool takes zero parameters, so per the baseline this scores 4; there is nothing for the description to clarify about arguments.

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?

The description names the specific resource ('The Forge agents you own') and enumerates the returned identity fields, which is enough for an agent to tell this apart from siblings like agents_directory (all agents) or agent_create. The verb is only implicit, but the possessive scope makes the operation 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?

The only guidance is a prerequisite ('Requires a JWT'); there is no explicit statement of when to pick this over agents_directory or agent_desk. Usage is implied by the 'you own' framing rather than stated, so it sits at minimum-viable.

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