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

No annotations are provided, so the description carries the burden. 'Preview' implies a non-mutating read and it discloses the api_key requirement, but it says nothing about return shape, limits, or rate behavior for a tool that is meant to inform a later publish decision.

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?

Front-loaded with the purpose, then usage, then the api_key requirement — no wasted preamble. The trailing 'Covers Skill 9c (PRD Skill 6 tool list)' is internal taxonomy noise that adds little for a calling agent.

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 description does well to say it previews candidate Agents and is used to pick prefer_agent_ids, implying the return is a candidate pool. It covers the auth requirement and the workflow role, though it omits any hint at pagination or candidate record fields.

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%, so all three parameters (limit, skills, api_key) are already documented; baseline is 3. The description adds only the linkage to prefer_agent_ids on the publish call, not syntax or matching semantics beyond the schema.

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: previewing skill-matched Agents for a Help Wanted request. The 'before you publish' framing cleanly separates it from help_wanted_publish, so the agent can distinguish it from siblings without opening the schema.

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?

Explicitly says when to use it ('estimate the candidate pool and pick prefer_agent_ids for the publish call') and ties it into a concrete workflow step before publishing. No when-not guidance or named alternatives, but the pre-publish context is clear.

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