validate_vhal_sources_and_enhance_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 discloses source URL validation, confidence scoring, alternative source suggestions, and transparency about cached vs. live data. While it doesn't discuss error handling or side effects, the disclosed behaviors are substantial for a read/analysis tool.

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 structured with a summary, bullet-list of features, and an Args/Returns section. It is somewhat verbose but well organized; each section earns its place, and key information is front-loaded.

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?

The description provides a complete picture: it explains the enhanced features, parameter semantics, and return value description. Given the output schema exists, the return description is bonus content. Missing details like rate limits are not critical for this read tool.

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 0%, and the description compensates by explaining all three parameters: question, include_source_validation, and max_sources_to_check, including defaults. This adds meaningful semantics beyond the bare schema and is exactly the kind of compensation needed.

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 provides an enhanced vHAL summary with source validation and transparency, listing specific features such as confidence scoring and citations. This is a specific verb+resource and distinguishes it from the sibling summarize_vhal tool, which likely lacks validation.

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 implies use when enhanced summaries with source validation and transparency are needed, providing clear context. However, it does not explicitly compare to alternatives like summarize_vhal or state when not to use this tool, so it lacks explicit exclusions or alternative mentions.

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