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

Annotations already declare destructiveHint=true and idempotentHint=false, so permanence is partly specified. The description adds 'for good', reinforcing irreversibility, but says nothing about what happens to line items, whether permissions or confirmations are required, or whether a deleted estimate can be recovered.

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 short sentence with the key qualifier front-loaded. It is efficient, though its brevity leaves little room for operational context.

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 one-parameter destructive tool, annotations carry the safety profile and the schema documents the ID source. Still missing is any note on side effects (linked items, totals) or failure conditions, which an agent deleting an estimate would want to know.

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 100% and the single estimate_id parameter is documented with 'From list_estimates.' The description contributes no additional parameter meaning, so the baseline 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?

States a specific verb (deletes) and resource (an estimate), and the phrase 'for good' clarifies the operation is permanent rather than archival. The name and title already distinguish it from siblings, but the description itself does not mention alternatives such as delete_change_order or remove_estimate_items.

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?

There is no guidance on when to delete versus update_estimate or remove_estimate_items, and no stated preconditions. The reader must infer usage entirely from the name.

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