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

Discloses idempotent behavior in the deleted-transaction case, going beyond the annotations. It does not describe all side effects on the income record, but the annotations and description are consistent.

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 with no filler. The action and safety note are front-loaded and immediately clear.

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?

Sufficiently complete for a simple operation with no output schema. It covers the action, parameters, and an important edge case, though it could theoretically mention the effect on the income record's status.

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 input schema already fully describes both parameters with clear definitions. The description adds minimal extra meaning beyond 'currently-linked' for transactionid, so it meets but does not exceed the baseline.

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?

Clearly states the verb 'Detach' and the specific objects: an income record from its bank transaction. This distinguishes it from broader siblings like unlink_entities.

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?

Provides useful safety guidance for an edge case (transaction already deleted without being unlinked), which helps the agent know when it is safe to call. It does not explicitly compare to alternatives but offers practical usage context.

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