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

With no annotations, the description carries the behavioral load well: it discloses that funds are drawn from the room balance, that execution is immediate, that settlement happens only after verification, and that an approval gate can defer it. It omits what happens on verification failure, whether funds are held or returned, and whether the call is reversible.

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 dense sentences with the primary action and funding source front-loaded, followed by the conditional branch. No filler and nothing repeated from the title or schema.

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 mutation tool with no annotations and no output schema, the description covers the critical workflow: cost source, timing, verification, and the approval branch. The notable gap is post-call behavior — there is no hint about what a caller gets back or how to check the hire's outcome, which matters more here because no output schema exists.

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 coverage is 100%, so all four parameters are already documented, and the baseline is 3. The description adds a little meaning by tying price to an approval line, but never explicitly connects that threshold to the max_price parameter or explains how max_price interacts with the room balance.

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 ('Hire a house specialist'), narrows scope with the specialist types (research, copy, design), and names the funding source (room balance). The approval-line clause implicitly separates it from approve_hire, so an agent can tell this is the initiating action rather than the approval action.

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?

Gives clear conditional usage: it runs immediately in the normal case and defers to approve_hire when the price exceeds the approval line, naming the alternative tool explicitly. It stops short of stating prerequisites (e.g. sufficient room balance, refund path on failure) or when not to hire at all.

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