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

Annotations already declare destructiveHint=true, idempotentHint=true, readOnlyHint=false, so the safety profile is largely covered. The description adds the non-annotated 'Confirm first' requirement and clarifies the deletion scope, but says nothing about irreversibility, permissions, or what happens to dependent data.

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 short sentences, front-loaded with the verb and affected resources, with the confirmation caveat placed last. No filler.

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?

An output schema exists and annotations carry the destructive/idempotent profile, so the description needn't explain returns. What it adds — entity kinds, id scoping, confirm-first — is nearly sufficient; a note on irreversibility or failure modes would close the remaining gap for a destructive tool.

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 0%, so the description must compensate, and it does part of the job: it enumerates the six valid kinds and the phrase 'from the matching list' conveys the non-obvious fact that record_id is scoped per kind. It lacks type/format detail for record_id, but the id-scoping insight is genuinely valuable beyond the schema.

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?

Opens with a specific verb ('Deletes') and enumerates the six resource types plus the lookup key ('by its id'), so an agent knows exactly what it removes. It does not differentiate against the near-neighbor sibling delete_budget, nor clarify that deleting a 'baseline' is different from freeze_baseline, so it stops short of full sibling discrimination.

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?

'Confirm first' is the only procedural guidance, which is a useful workflow hint but not an when-to-use/when-not-to-use rule. Nothing tells the agent when to prefer this over delete_budget or freeze_baseline, or what preconditions exist before deletion.

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