vcv_read

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

With no annotations provided, the description carries the full behavioral burden, and it does provide useful detail about what the tool exposes: Rack version, modules, cables, asset list, and a summary. 'Read' conveys a non-mutating operation, though the description could have clarified error behaviors or file-format expectations.

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. It states the core action first and then lists the returned content without any filler or redundant restatement of the tool name.

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 simple read tool with one parameter and an output schema present, the description provides enough context about what the tool does and what it returns. It could be slightly more complete with explicit mention of file-not-found or invalid-format behavior, but those are minor gaps.

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 schema has a single 'path' parameter with no description coverage. The description indirectly clarifies that path should refer to a .vcv file, but it does not add explicit detail about path format, validation, or accepted file variations beyond the extension.

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 begins with a specific verb and resource: 'Read a .vcv file' and then lists exactly what is included: Rack version, modules, cables, asset list, and a text summary. This clearly distinguishes it from sibling tools like vcv_write, vcv_create, and vcv_validate, which imply different operations.

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 this tool is for reading/inspecting an existing .vcv file, which is reasonable, but it does not explicitly state when to choose it over alternatives or when not to use it. No sibling tool is referenced as an alternative, so the guidance is only implicit.

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