session_unblock

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

No annotations are provided, so the description carries the full behavioral burden. It discloses the core behavior and the special empty-string-all semantics, but it adds no context about scope, side effects, persistence, or any effects on existing blocked patterns.

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, front-loaded sentence states the action, the parameter behavior, and the special all-case. Every word earns its place.

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 with an output schema and no nested objects, the description is largely complete. It explains the only input and the expected operation; broader usage caveats or side-effect details might be nice, but they are not essential for correct invocation.

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%, yet the description compensates by defining the actual meaning of the only parameter: a pattern unblocks matching requests, while an empty string unblocks all. This adds valuable semantics beyond the bare field title.

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 concrete action ('remove block') and a clear resource ('request blocking'), along with the two operational modes: by pattern or for all requests. It does not explicitly name sibling session_block, but the purpose is still precise and distinguishable.

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 usage is implied: it is the tool for removing request blocks, and an empty string means unblock everything. However, there is no explicit guidance on when to use this tool versus alternatives or what conditions require a pattern versus an empty string.

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