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

With no annotations present, the description carries the full burden and does substantial work: response style (studio's voice, one short line), the returned artifacts (brief so far, open call times, starting price, closest work, brief page), the confirmation-to-studio handoff, and a stated human response latency of one working day. It does not mention authentication, rate limits, or what happens to an unconfirmed brief, which keeps it from a 5.

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?

The core action is front-loaded in the first clause and the return/escalation details follow in a logical order. It is dense but somewhat run-on, with the continuation instruction and the working-day reply SLA packed into a single long second sentence. No sentence is clearly disposable.

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?

There is no output schema, so the description must explain return values, and it does list them. It also covers session continuity and the human handoff latency. What is missing is how the returned fields are shaped (e.g., whether open call times are formatted strings or objects) and any failure or ambiguity handling.

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 the baseline would be 3, but the description adds real meaning about message content — that the client can describe the project, ask questions, and name a call time in words rather than in a structured slot. It also reinforces the conversation_id continuation contract, which the schema states more tersely. on_behalf_of is not elaborated beyond its schema description.

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 a concrete verb and resource — talking to The Leos' own agent in plain language — and enumerates the topics it handles (work, starting prices, studio rental and kit, the team) plus the call-time booking. That is far more specific than a tautology. It stops short of explicitly distinguishing itself from siblings like list_services, estimate_budget or request_call, whose subject matter it overlaps.

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?

It gives one explicit procedural rule — pass conversation_id from the last reply to continue the same brief — and describes the escalation path once a brief is confirmed. It never says when an agent should prefer this conversational tool over check_availability, estimate_budget or submit_brief, even though the described capabilities overlap all three, so routing must be inferred.

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