Delete a journal entry

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the core write behavior is known. The description adds genuinely useful context beyond the annotations: a CalDAV server keeps no history, deletion is irreversible, and the note represents someone's writing. This aligns with the annotations and deepens the agent's understanding of consequences.

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 crisp sentences with no filler. The action is front-loaded, and the consequence is stated immediately. Every word contributes to either purpose or behavioral risk.

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?

The combination of a complete input schema, an output schema, and annotations covers the mechanical requirements for calling the tool. The description supplies the essential non-schema context: the irrevocable nature of the deletion. It is sufficient for an agent to invoke the tool correctly, though it could have briefly mentioned the two-step confirm_token workflow.

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?

Schema description coverage is 100%, and the schema already provides clear semantics for both parameters: id must come from a listing tool, and confirm_token comes from the first call of this tool. The description itself adds no additional parameter-level meaning, so the baseline score of 3 applies.

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 identifies the action ('Removes') and the resource ('a dated note'), which maps cleanly to a journal entry and distinguishes it from event or task deletion. It does not explicitly differentiate from sibling delete tools by name, but the resource wording is specific enough for practical selection.

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 provides no guidance on when to use this tool versus alternatives such as delete_event or delete_task, nor does it state conditions or prerequisites. The irreversibility warning implies caution, but it does not actually help route an agent to the correct delete tool.

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