update_ticket_status

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

With no annotations provided, the description carries the full burden. It clearly discloses the mutating nature ('WRITE operation') and the data target (BigQuery), plus the human-approval requirement. However, it does not mention potential side effects (e.g., whether the status update is irreversible or whether prior status is overwritten), which would strengthen transparency further.

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 description is two sentences, front-loaded with the most important fact ('WRITE operation'), and contains zero filler. Every word contributes value, making it highly efficient and scannable for an 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?

Given the absence of an output schema, the description does not specify what the tool returns after a successful update, which is a minor gap. However, it covers the mutation, the target, the status values, and the usage constraint, which is sufficient for an agent to invoke it correctly. The missing return semantics is not critical for a write operation.

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 0%, so the description must compensate. It provides the allowed values for new_status and notes that the note is optional, which are not in the schema. It does not elaborate on ticket_id beyond the schema's type string, but the description adds meaningful context for two of the three parameters.

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 states a specific verb ('Updates') with a precise resource (ticket status) and enumerates the allowed values ('open', 'pending', 'resolved'). It also explicitly distinguishes itself as the only write operation among the siblings, so an agent can clearly identify its unique role.

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 explicit when-to-use guidance: only after a human has reviewed and approved a draft_reply or suggest_escalation result, and explicitly prohibits autonomous calls. This fully satisfies the dimension and leaves no ambiguity about the appropriate trigger context.

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