unblock_client

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

With no annotations, the description carries the behavioral disclosure burden. It clearly states the action and the precondition ('previously blocked'), but it does not mention reversibility, permissions, idempotency, or side effects beyond the core unblock operation.

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 three short lines with no filler. The purpose is front-loaded, and parameter guidance is compact and directly actionable.

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?

The description covers the main precondition and fully documents parameter semantics, and the output schema handles return details. It could add guidance on edge cases like unblocking a client that isn't currently blocked, but this is minor for a simple targeted action.

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 0%, but the description compensates fully: it explains accepted forms for host and site and gives an exact source and field for client_id. Every parameter is given meaningful guidance beyond the raw schema.

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 uses a specific verb ('Unblock') and resource ('previously blocked client'), and scopes it to a site. This clearly distinguishes it from the sibling block_client and other client-action 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?

It provides useful procedural guidance—client_id must come from list_clients—and marks it as REQUIRED. However, it does not explicitly state when to choose this tool over related actions like execute_client_action or block_client, nor how to handle an already-unblocked client.

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