create_firewall

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

With no annotations provided, the description carries the full burden of behavioral disclosure but fails to do so. It doesn't indicate whether this is a mutating operation, what permissions are required, if it's idempotent, or what happens on success/failure. The word 'create' implies mutation but lacks critical details like rate limits or side effects.

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 extremely concise with a single sentence that wastes no words. While under-informative, it is front-loaded and efficiently phrased without redundancy or unnecessary elaboration.

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 mutating tool with 3 parameters (including complex types), 0% schema coverage, no annotations, and no output schema, the description is completely inadequate. It fails to explain what the tool does beyond the obvious, leaving critical gaps in understanding behavior, parameters, and usage context.

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 description coverage is 0%, meaning none of the three parameters (name, rules, labels) are documented in the schema. The description provides no information about these parameters—their purposes, formats, or constraints—leaving them completely unexplained despite the presence of complex types like arrays and nested objects.

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 'Create a new firewall' is a tautology that restates the tool name without adding meaningful specificity. It mentions the verb 'create' and resource 'firewall' but lacks details about what a firewall entails in this context or how it differs from other creation tools like create_network or create_server.

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?

No guidance is provided on when to use this tool versus alternatives. It doesn't mention prerequisites, dependencies, or comparisons with sibling tools like list_firewalls, update_firewall, or delete_firewall, leaving the agent with no context for decision-making.

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