trmm_agent_event_log

Read-onlyIdempotent

Retrieve Windows event log entries from a managed agent, filtering by log type, level, and message substring to diagnose issues.

Instructions

Windows event log entries from an agent. log_type is Application, System or Security. Filter by level (error/warning/information) and an optional message substring.

B3.4/5.0

Behavior3/5

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

Annotations already declare readOnlyHint, openWorldHint, idempotentHint, and non-destructive behavior, so the safety profile is covered. The description adds log type and filter context but does not disclose output shape, pagination behavior, or event-source caveats, leaving some behavioral detail undisclosed.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is two short sentences with no filler and front-loads the core resource. It could be improved with a clearer verb, but it is efficient and every sentence contributes useful information.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

For a read-only, six-parameter tool with no output schema, the description covers the core object and main filters but omits return-value shape and full parameter semantics for days and limit. It is adequate for basic calls but leaves gaps an agent may need to infer.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 0%, so the description carries the burden for parameter meaning. It explains log_type values, level values, and the search substring, but it does not clarify the meaning of days, limit, or how the agent identifier should be provided, though schema defaults partially mitigate days and limit.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description identifies the resource as Windows event log entries from an agent and names the log types (Application, System, Security). This is clear enough to distinguish it from sibling agent inspection tools like services, processes, or software, though it lacks an explicit verb such as 'Retrieves'.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description implies when to use the tool: to inspect Windows event log entries for an agent, with optional filtering by level and message substring. It does not explicitly state when not to use it or how it compares to related tools like trmm_agent_history or trmm_audit_log, so the usage context is only implicit.

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