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

With no annotations provided, the description carries the full disclosure burden but fails to specify critical behavioral traits: idempotency (whether calling twice errors), immediate vs. eventual effect on firewall rules, or what occurs if the package isn't on the denylist.

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 single sentence is appropriately sized with zero redundancy. Every word earns its place by stating the action, object, and location of the operation.

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 simple two-parameter mutation tool with complete schema coverage and no output schema, the description is minimally sufficient for invocation. However, it lacks completeness regarding error handling, side effects on active connections, or confirmation of success criteria.

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%, establishing a baseline of 3. The description adds minimal semantic value beyond the schema—it confirms the 'firewall_id' relates to a denylist context and that 'package_name' refers to the blocked entity, but does not elaborate on package naming formats or firewall ID formats.

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 provides a specific verb (Remove) and resource (package from a firewall's denylist), clearly indicating the tool's function. It implicitly distinguishes from siblings like 'add_to_denylist' and 'remove_from_allowlist' through specific resource naming, though it lacks explicit comparative guidance.

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 description offers no guidance on when to use this tool versus alternatives like 'add_to_allowlist' for unblocking traffic, nor does it mention prerequisites such as verifying the package is currently on the denylist (e.g., via 'check_package').

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