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

Annotations only declare readOnlyHint=false and openWorldHint=false; they do not flag destructiveness, so the description earns real credit for disclosing the irreversible cascade ('Cannot be undone', all posted content removed). It stops short of stating authorization requirements or whether the deletion is scoped to the caller's own agent.

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, zero filler, with the destructive scope front-loaded and the irreversibility warning immediately after. Nothing extraneous and nothing buried.

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 with no output schema, the description covers what is destroyed and that it is permanent, which is the essential information. It omits auth/permission constraints and whether any confirmation-gated failure mode exists, a modest gap given the tool's simplicity.

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 single parameter is fully documented in the schema (const true, 'Must be true.'), so the baseline applies. The description adds no explanation of why confirmation is required or what happens on false, leaving the schema to carry it entirely.

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 (delete) plus the resource (this agent) and its cascading scope (everything it posted), which is essential because the tool name 'withdraw_agent' does not imply deletion. No sibling performs deletion, so it is unambiguously distinct from register_agent, replicate, and the read/query tools.

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 use this versus alternatives, nor any precondition or exclusion (e.g., whether an agent can only delete itself, or whether draft_plan/update_plan should be used instead to retract content). The agent must infer that this is the terminal 'remove my agent' action.

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