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

Annotations already establish this as a readOnly, idempotent, non-destructive operation, so the safety profile is covered. The description adds genuinely useful outcome semantics beyond that: what REFUSED means operationally (do not say it, do not invent a substitute) and the constraint on APPROVED wording, plus the conditional effect of passing channel.

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?

Four short sentences, front-loaded with the core decision, then outcome semantics, then the optional parameter effect. No filler. Slight opacity in the bare term 'sayOnly' (an output field not defined here) is the only friction.

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?

An output schema exists, so return values need not be restated, and the description still usefully clarifies APPROVED/REFUSED semantics. The remaining gap is that deskId's role and how the approved set is scoped are never addressed, which matters for a decision tool with a required deskId.

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 carry parameter meaning. It explains the 'kind' space implicitly (refund/feature/timeline) and gives the behavioral effect of 'channel' (enforcing the escalation limit), but deskId and the proposal string format/length are left completely unexplained.

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: deciding whether a proposed refund/feature/timeline is 'in the approved set', which maps directly onto the REFUND/FEATURE/TIMELINE enum. It is clearly distinct from list_approved_commitments, but it never names or contrasts with its closest sibling evaluate_escalation, leaving that differentiation to inference.

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 hints at usage via 'Pass channel to also enforce the escalation limit', which tells the agent one behavioral condition for invoking it. However, it never says when to reach for this tool versus evaluate_escalation or list_approved_commitments, so the routing guidance is only implied.

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