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

With no annotations, the description carries the full behavioral burden. It discloses the cascade (key revocation, membership removal, task unassignment), the fallback behavior when history rows block deletion (deactivate instead of delete), the returned status value, and permission requirements. This is exactly the kind of context an agent needs before invoking a destructive tool.

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?

The description is a single, front-loaded sentence that packs a lot of information without waste. It could be slightly tightened, but it remains readable and efficient.

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 destructive tool with no annotations and no output schema, the description covers all critical aspects: what gets destroyed, the fallback deactivation, the returned status, and auth requirements. An agent can invoke it correctly with confidence.

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% – both agent_username and namespace_slug are fully documented in the schema. The description adds no parameter-specific details beyond what the schema provides, so baseline 3 is appropriate.

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 and resource ('Delete an agent account') and immediately enumerates what deletion entails (revokes API keys, removes memberships, unassigns tasks, hard-deletes user). This distinguishes it clearly from siblings like revoke_agent_key and delete_task, which handle narrower operations.

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?

The description implies when to use it: to fully remove an agent. However, it does not explicitly contrast with restore/revoke alternatives or state when NOT to use it. The permission requirement ('Requires organization owner/admin') adds a useful precondition.

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