Unblock client

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

Annotations already declare the safety profile (readOnlyHint=false, destructiveHint=true, idempotentHint=true, openWorldHint=false), so the mutation and repeatability semantics are covered structurally. The description adds only the 'previously blocked' state constraint; it does not explain that unblocking restores network access, whether it requires admin auth, or whether the change is immediate.

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 clause that front-loads the action, the target, and the identifier. No filler, nothing repeated from the title.

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 tool whose annotations already carry the safety and idempotency profile and which has no output schema, the description is nearly sufficient. The only real gap is the absence of the block/unblock relationship to sibling tools, which an agent could infer but not confirm from this text alone.

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 the single mac parameter is already documented with a concrete example format (aa:bb:cc:dd:ee:ff). The description names the MAC address as the lookup key but adds no format or matching nuance beyond the schema, 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 description states a specific verb ('Unblock') and resource ('client') plus the identifying key (MAC address), which cleanly separates it from the sibling block_client. It stops short of naming the sibling tool or its inverse, so differentiation is inferable rather than explicit.

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 phrase 'previously blocked client' implies the precondition for use, but there is no explicit when-to-use guidance, no mention of the block_client counterpart that creates the state being undone, and no exclusions or prerequisites such as required permissions.

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