journal_entry__reversal

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

With no annotations, the description only states 'Flip Dr/Cr'. It does not disclose whether the operation is destructive, requires permissions, or other behavioral traits. The description fails to add meaningful context beyond the bare action.

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?

While very concise (one sentence), it is under-specified. A single sentence is insufficient to convey necessary details, making it too short to be effective.

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 complexity of accounting reversals and the lack of output schema or annotations, the description is incomplete. It does not explain what an accrual reversal is, the expected format of input lines, or what the tool returns.

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?

The schema has 1 parameter 'lines' with 0% description coverage. The description only says 'Flip Dr/Cr for an accrual reversal', offering no explanation of what the 'lines' array should contain (e.g., journal entry line items, structure). The description does not compensate for the missing schema documentation.

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 clearly states the tool flips Dr/Cr for an accrual reversal. The verb 'Flip' and resource 'Dr/Cr for an accrual reversal' are specific. It distinguishes from siblings like journal_entry__prorate_accrual and journal_entry__validate_entry by focusing on reversal, but does not explicitly contrast.

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?

No guidance on when to use this tool vs alternatives. It does not mention prerequisites, context for reversal, or when not to use it.

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