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

Annotations already declare destructiveHint=true and readOnlyHint=false, so the safety profile is covered structurally. The description adds nothing beyond that: it does not say the removal is irreversible, what happens to the number or secret, or whether inbound calls are dropped immediately.

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?

A single short sentence with no padding, which is concise. But the brevity comes at the cost of substance rather than from efficiency, and there is no front-loaded guidance beyond the bare action.

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, irreversible two-parameter operation with no output schema, the description omits consequences, recovery path, and failure modes (e.g. wrong secret). It is far too thin relative to the complexity and risk of the tool.

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% and both parameters are documented ('Your agent's number' and 'The secret call_register_agent returned'). The description adds no additional meaning, 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?

The sentence names a specific action and resource ('take your agent off the Privi Call network'), so the intent is graspable. However, it is essentially a paraphrase of the title 'Remove your agent from the network' and gives no signal distinguishing it from call_register_agent or the other siblings.

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 anything else, no mention that re-registration is required to rejoin, and no prerequisites such as holding the secret from call_register_agent. The agent must infer everything from the name.

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