Preview: Restore an invoice

preview_restore_invoice

Read-onlyIdempotent

Prepare restoring an exact invoice from restorable trash. Requires confirmation, edit and workspace invoice-view permissions. This returns an exact preview and a five-minute confirmation token; it does not apply the change.

Tool call template

Replace each placeholder with a value matching the input schema. Only required parameters are included; add optional parameters as needed.

A4.2/5.0

Behavior4/5

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

Annotations already declare readOnlyHint/idempotent/non-destructive, and the description adds real value beyond them: the five-minute token lifetime, the permission requirements, and the explicit statement that no change is applied. Return shape detail is modest but the safety profile is fully covered.

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

Conciseness5/5

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

Two sentences, no waste, with the core action front-loaded and the non-mutating caveat immediately after. Every clause carries information.

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

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a single-parameter preview tool with no output schema, the description supplies what an agent needs: what it returns (preview plus expiring token), that it is non-mutating, and the permission gate. Only the preview payload's contents are left implicit.

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

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, but there is only one parameter, invoice_id (uuid), whose meaning is self-evident from its name. The description's phrase 'an exact invoice' hints that a precise identifier is required but adds no format or sourcing detail.

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

Purpose5/5

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

States a specific verb ('Prepare restoring') and resource ('an exact invoice from restorable trash'), and explicitly frames it as a non-applying preview, which separates it from restore_invoice.

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

Usage Guidelines4/5

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

Explains the gating conditions (confirmation, edit and workspace invoice-view permissions) and clarifies it does not apply the change, implying the follow-up commit call. It stops short of naming restore_invoice as the alternative that consumes the token.

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