get_security_posture_summary

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

With no annotations provided, the description carries the full burden. It clearly states the tool parses a file and produces a summary, implying a non-destructive read operation. It lacks explicit mention of error handling or file requirements, but for a simple parsing tool, the behavioral description is adequate and transparent.

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, information-packed sentence followed by a brief usage cue. It is front-loaded with the action and resource, lists key outputs efficiently, and contains no filler.

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 one-parameter parsing tool, the description is complete: it specifies the input file, the output structure, and its place in the workflow relative to siblings. No output schema exists, but the description enumerates the return components, so the agent knows what to expect.

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 already covers the sole parameter (resultsFile) at 100%. The description adds value by linking the file to the output of run_maester_tests ('Maester results file') and framing it as the post-run summary step, which enriches the parameter's meaning 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?

The description states a specific verb ('Parse') and resource ('a results file'), and enumerates the output components (overall pass rate, per-category breakdown, sorted critical/high failures, top failures). It clearly distinguishes itself from siblings like run_maester_tests (which runs tests) and get_failed_tests (which likely lists failures).

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 explicitly recommends when to use it: 'Good first call after run_maester_tests.' This provides clear context and a suggested workflow. However, it does not name alternatives or state when not to use it, so it falls short of the top score.

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