delete_blood_pressure

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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the mutation profile is covered. The description adds genuine value beyond that by flagging the operation as IRREVERSIBLE and mandating user confirmation, which is a behavioral workflow constraint not expressible in annotations. It does not, however, describe failure modes (e.g., stale version) or permission requirements.

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?

The core content is short and the IRREVERSIBLE warning is appropriately emphasized. But the first sentence is repeated verbatim, which is pure redundancy and pushes the actionable warning later than necessary.

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?

For a destructive mutation with no output schema, the description covers the essential safety story (irreversible, confirm first) and identifier provenance. It leaves gaps around the role of the required `cdate` parameter and any post-condition or return behavior, which an agent calling a delete would benefit from knowing.

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 coverage is 50%: `cdate` is documented in-schema, but `version` has no schema description. The description partially compensates by explaining where `version` comes from (`get_blood_pressure`), but it never explains what `cdate` contributes to a delete or how the two fields interact to identify a reading.

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?

States a specific verb (deletes) and resource (one blood-pressure reading) qualified by the identifier (`version`). It is clearly distinguishable from sibling deletes like delete_weigh_in or delete_custom_food. It stops short of a 5 because the duplicated sentence and the mismatched reference `getBloodPressure` (vs. sibling `get_blood_pressure`) introduce noise rather than sharper scoping.

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?

Gives real usage context: the `version` value must be sourced from a prior read (`get_blood_pressure`), and the user must confirm before the call. However, there is no explicit when-not guidance and no mention of the alternative path (e.g., updating instead of deleting, or batch-deletion siblings).

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