Renew Package

renew_package

Renew: a prior quote id from the retailer's program and a new approved budget. Without a quote id from the program there is nothing to renew.

B3/5.0

Behavior3/5

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

Annotations already declare this is a non-read-only, non-idempotent, open-world, non-destructive write, so the mutation profile is covered. The description adds the prior-quote-id precondition, which is real behavioral context, but says nothing about permissions (the budget_approved_by parameter hints at an approver requirement without explaining it) or side effects. With annotations carrying safety, a 3 is appropriate.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two short sentences with the operative verb 'Renew' front-loaded and zero filler. The first sentence is telegraphic ('Renew: a prior quote id ... and a new approved budget'), which slightly hurts readability but keeps it tight.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

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 described, and the precondition is stated. Still, for a mutation tool the description leaves the optional decision_id unexplained and gives no indication of how this differs from the closely-named quote_package sibling, so it is only minimally complete.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

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 and only partially does: it maps prior_quote_id and budget (the 'new approved budget'). budget_approved_by and decision_id are never mentioned, and decision_id being nullable with a default is left entirely unexplained. Two of four parameters remain undocumented in both schema and description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose3/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description states the verb 'Renew' and hints at the resource by tying it to a prior quote id and a new approved budget, so an agent can tell roughly what happens. However it never names the resource being renewed (package/quote) and offers no differentiation from siblings like quote_package or list_packages. Purpose is inferable but not crisp.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

It supplies a precondition — 'Without a quote id from the program there is nothing to renew' — which implies when this tool is applicable versus when it is not. It does not, however, contrast the tool against alternatives such as quote_package or gate_transaction, so usage guidance is implied rather than explicit.

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