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

Annotations already declare destructiveHint=true, idempotentHint=true and readOnlyHint=false, so the safety profile is covered. The description adds useful narrowing context (app-sourced only, family-scoped log), but says nothing about reversibility, permissions, or what happens if the id is unknown. No contradiction with annotations.

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?

A single compact sentence with the scope qualifier front-loaded and no filler. Appropriately sized for a one-parameter delete tool.

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 simple destructive delete with annotations covering the safety profile and no output schema, the description is adequate but thin: it omits the id's provenance and any note on failure behavior when the event does not exist.

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 single 'id' parameter has 0% schema description coverage, so the description carries the burden and only says 'by id'. It does not state what kind of id this is or where to obtain it (e.g., from get_events), leaving the one required input under-specified.

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 (Remove) plus a tightly scoped resource: a previously logged app-sourced event, identified by id, in the family's log. An agent can distinguish it from edit_event (modify vs. remove) and from the log_* writers. It stops short of naming a sibling alternative explicitly, so it lands at 4 rather than 5.

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?

Usage is implied rather than stated: the qualifier 'previously logged app-sourced event' acts as a precondition, implying this is for removing existing app-created events. There is no explicit when-to-use/when-not-to-use and no mention of undo_last or edit_event as alternatives for reversing or amending an entry.

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