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

Annotations already declare destructiveHint=true, idempotentHint=true and openWorldHint=false, so the safety profile is known. The description nevertheless adds two genuinely new facts: the no-op case returns 204 rather than an error, and the call consumes no credits — the latter being billing context found nowhere in the structured fields. It does not say whether anything beyond the profile record (discovery results, generated messages) is affected, so it stops short of a 5.

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 plus a bolded cost note, all front-loaded with no filler. The tradeoff is that the terseness leaves key facts (which profile, what else is removed) unexplained rather than that words are 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?

With no input parameters and no output schema, the definition is nearly complete — the 204 return behavior is covered and credits are addressed. Missing is any indication of scope or reversibility: whether this is a soft or hard delete, and whether dependent artifacts survive, which is material for an irreversible destructive call.

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 tool takes zero parameters, so the schema baseline of 4 applies. There is no parameter meaning for the description to add or omit.

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?

"Removes the profile" states a verb and an object, but the object is referred to only as "the profile" and never qualified as the seller profile. Against siblings like delete-nothing, disconnect_crm, cancel_discovery and cancel_message_generation, an agent must fall back on the tool name alone to know which resource is being removed.

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 statement of when to use this versus alternatives (e.g. resetting vs. disconnecting an integration), and no prerequisites or preconditions. The only usage-adjacent content is the note that calling it when no profile exists still succeeds, which is a behavior, not a usage rule.

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