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

Annotations already declare destructiveHint=true, idempotentHint=false, and openWorldHint=true, so the safety profile is covered. The description adds one genuinely useful consequence — that existing labels made with the package survive — but says nothing about irreversibility, permissions, or what happens to shipments referencing the package.

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 with no filler, and the primary action is front-loaded ahead of the side-effect caveat. It could name the alternative or prerequisite in the same space, but nothing is wasted.

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 delete with full schema coverage, no output schema, and annotations covering the destructive/non-idempotent profile, this is nearly complete. The only real omission is confirmation or irreversibility guidance.

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 description coverage is 100% and the single parameter package_id is already documented as 'id from list_saved_packages.' The description adds no further meaning beyond the schema, so the baseline 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 (removes) and resource (Saved Package), which is unambiguous and distinct from siblings like create_saved_package, update_saved_package, and list_saved_packages. It does not explicitly name those siblings, but the verb makes the distinction obvious.

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?

Deletion intent is implied by 'Removes', but there is no explicit when-to-use framing, no mention of when to use update_saved_package instead, and no prerequisites such as confirming the package is unused. Usage is inferable rather than stated.

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