Delete water entry

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

Annotations already provide destructiveHint=true and idempotentHint=true. Description adds 'local' context and the explicit intent requirement, but does not detail behavior on missing id or side effects. Value beyond annotations is moderate.

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?

Single sentence of 9 words, front-loaded with action verb. No extraneous information.

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?

Simple delete operation; description covers core purpose and condition. Could mention idempotency or effect of non-existent id, but annotations suffice. Nearly complete given tool simplicity.

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 covers id and explicit_user_intent (67%). Description only reinforces the intent parameter; it does not add new meaning beyond the schema. Response_format lacks description but is self-explanatory. Baseline 3.

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?

Description clearly states the verb 'Delete', resource 'single local hydration entry', and constraint 'by id after explicit user intent', distinguishing it from siblings like nourish_delete_intake (food) and nourish_clear_hydration_day (clear day).

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?

Description includes condition 'after explicit user intent', reinforced by the explicit_user_intent parameter. However, it does not explicitly state when not to use or mention alternatives like nourish_delete_intake for food entries.

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