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

The description explains the concrete mutation: the first entry is reposted and the counterpart is excluded to avoid double counting. This goes beyond the annotations by detailing exactly what the confirmation changes.

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?

Two concise sentences, front-loaded with the core action and a clear explanation of the side effect. No padding.

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?

Explains the core behavior and side effect, but does not mention what the counterpart status changes to, reversibility, or prerequisites. Relative to its siblings (suggest_transfer_pairs, unpair_transfer), it lacks workflow context.

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 description clarifies that the first-named entry is the one reposted and the counterpart is excluded, adding meaning to the two entry IDs beyond their parameter names and type. This helps an agent pick which ID goes where.

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 action (confirm) and the object (two journal entries as a transfer pair), then specifies outcomes (first entry reposted, counterpart excluded). This gives an agent an unambiguous understanding of what the tool accomplishes.

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?

The description explains the effect of confirming but provides no explicit guidance on when to use it relative to siblings like accounting_suggest_transfer_pairs or accounting_unpair_transfer. An agent must infer the workflow context.

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