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

readOnlyHint=true already tells the agent this is a non-mutating call, lowering the bar. The description adds the useful cardinality constraint 'exactly one', but says nothing about whether repeated calls yield the same target, whether a session/state must exist first, or what the caller is expected to do with the result.

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. It is efficient, though 'immediately useful' is promotional rather than informative and the sentence is terse to the point of being under-specified.

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-param entry-point tool with no output schema, the description should at minimum say what a 'target' looks like and how it relates to the sibling action/escalate/handoff tools. As written, the agent has no picture of the return value or the follow-up path.

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 there is nothing for the description to disambiguate. No parameter-level gap exists.

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 verb 'Receive' plus the constraint 'exactly one' technically states what the tool returns, but 'solve or verification target' is domain jargon that is never defined, and nothing distinguishes it from siblings like waystation_read or waystation_search. An agent knows something comes back, not what class of object or why this tool rather than another.

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 statement that this is an entry point, and no mention of the sibling tools (waystation_action, waystation_escalate, waystation_read) that presumably follow or replace it. The agent must guess where this sits in the workflow.

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