MCP Action Firewall

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

Discloses key traits: 'simulated' (not real logging) and 'random-leveled' (randomized severity levels). However, with no annotations provided, fails to clarify persistence of state, default status, or return value behavior.

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?

Single sentence with zero waste. Front-loaded with action verb and precise scope. Every word ('simulated', 'random-leveled') adds meaningful context beyond the tool name.

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?

Adequately complete for a zero-parameter toggle operation. While lack of output schema or annotations leaves some behavioral gaps (new state vs void return), the description covers the essential contract for a simple state toggle.

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?

Input schema contains zero parameters. Per guidelines, baseline score is 4. Description appropriately implies no configuration needed via the simple toggle semantics.

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?

Uses specific verb 'Toggles' and clearly identifies the resource as 'simulated, random-leveled logging'. However, does not distinguish from sibling tool 'toggle-subscriber-updates' beyond naming the different target resource.

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?

Provides no guidance on when to use this tool versus alternatives, prerequisites for toggling, or side effects of enabling/disabling logging. Only states what the tool does, not when to invoke it.

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