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

Annotations already declare destructiveHint=true, readOnlyHint=false and idempotentHint=false, so the danger profile is covered structurally; the description's added value is the human-confirmation requirement, which annotations cannot express. It never states whether removal is permanent or recoverable, and it does not reconcile the idempotencyKey parameter with the idempotentHint=false annotation.

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 tight clauses with zero filler; the destructive action is stated first and the safety instruction second. It is appropriately sized for the operation, though front-loading "Confirm with the user first" before the parameter hint would read even better.

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 4-parameter destructive mutation with full schema coverage, no output schema, and annotations carrying the safety profile, the description covers purpose, parameter provenance, and the required human-in-the-loop step. The only real gap is not saying whether the removal is irreversible or how to restore the link.

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%, so all four parameters (including idempotencyKey's retry semantics and locationId fallback) are documented in the schema itself. The description only repeats the source of "name" already noted in the schema, adding no new parameter meaning. 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?

Specific verb and resource ("Remove an action link") plus a scope qualifier ("from the listing"), which cleanly separates it from create_gbp_action_link and update_gbp_action_link in the sibling list. It does not explicitly name those siblings, so it falls just short of 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?

"Confirm with the user first" gives an explicit precondition for invocation, and "(name from get_gbp_listing)" routes the agent to the sibling tool that supplies the identifier. There is no statement of when NOT to use it or what to do instead if the link should only be modified, so it stops short of 5.

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