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

No annotations provided, so description carries full burden. Uses 'recent' without defining the time window (24 hours? 30 days?). Does not disclose what activity types are returned (successes, failures, attempts?), sort order, or pagination behavior beyond the limit parameter.

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 efficiently conveys core purpose with no redundancy. However, brevity comes at cost of omitted behavioral context; the description is front-loaded but undersized for the complexity of temporal data retrieval without annotations.

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?

With no output schema and no annotations, description should explain return structure and temporal scope. 'Recent' is undefined, and there's no indication of what data structure is returned (array of events? log entries?). Missing critical context for agent to interpret results.

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%, so baseline applies. Description mentions 'for a firewall' which aligns with firewall_id parameter and implies temporal scope matching 'recent' to the limit parameter, but adds no syntax details, format requirements, or validation rules beyond the schema.

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?

States specific verb (Get), resource (package installation activity), and scope (recent, for a firewall). Distinguishes reasonably from mutation siblings (add/remove) but doesn't clarify distinction from 'check_package' which could be confused as a read operation.

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 versus check_package or list_firewalls. No information on prerequisites like firewall_id availability or permissions needed to access activity logs.

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