get_firewall_stats

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

There are no annotations, so the description carries the behavioral burden. 'Return' implies a read-only operation and the project_root instruction adds procedural context, but it does not disclose potential side effects, permission requirements, or whether statistics are cumulative or reset.

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?

Two sentences with no filler. The core purpose is front-loaded and the critical invocation instruction is concise and 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?

For a single-optional-parameter tool with an output schema, the description covers the essential invocation detail and return purpose. It does not discuss when to call it or edge cases, but the low complexity and output schema reduce that need.

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%, so the description must clarify the parameter. It explains that project_root should be set to the current working directory, which adds meaning beyond the raw schema and default value.

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 ('Return') and resource ('firewall statistics') with a clear scope ('current project'). It is unambiguous and naturally distinguishes from unrelated siblings like check_assumption and healthcheck.

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 explicit invocation guidance: 'Always pass project_root as the current working directory.' It does not name alternatives or exclusions, but no sibling tool performs a comparable function, so the guidance is sufficient.

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