evtx_get_stats

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

With no annotations, the description carries the burden of behavioral disclosure. It states the tool retrieves statistics, implying a read-only operation, and lists what statistics are returned. However, it does not describe potential constraints (e.g., file size limits), output format, or that it does not modify the file. This is adequate but lacks deeper context, leading to a mid-range score.

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 a single, well-front-loaded sentence that efficiently conveys purpose and output. No superfluous words; every part earns its place.

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?

Given the tool's simplicity (one parameter, no output schema) and the fact that it's a statistics-gathering tool, the description is largely complete. It names the statistical categories returned. However, it could improve by hinting at the output structure or recommended use cases, but for its complexity, it's sufficient.

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?

The input schema has 100% coverage with a single parameter 'evtx_path' described as 'Path to EVTX file'. The description does not add further meaning (e.g., accepted formats, absolute/relative paths). Thus, the description adds no value beyond the schema, meeting the baseline for high coverage.

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 clearly states the tool's purpose: 'Get statistics about an EVTX file' and specifies the output includes event counts, time range, and Event ID distribution. This distinguishes it from sibling EVTX tools like evtx_search (searching) and evtx_explain_event_id (explaining a single ID), making the purpose specific and unambiguous.

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 provides clear context: it is used to obtain summary statistics of an EVTX file. While it doesn't explicitly state when not to use it or name alternatives, the context implies it's for high-level overview before deeper analysis with other tools (e.g., evtx_search). This meets the 'clear context, no exclusions' level.

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