list_registered_toolchains

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

No annotations are provided, so the description carries the full burden. It indicates this is a read-only listing operation. However, it does not disclose whether any side effects occur, authorization requirements, or output details. The description adds some clarity but is minimal.

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 sentence that is clear and concise, with no extraneous words. It front-loads the purpose effectively.

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 no parameters and the presence of an output schema (though its contents are not detailed here), the description is somewhat complete. However, it could mention that it returns a list of toolchain identifiers or names, and that it is safe to call at any time. The lack of any behavioral notes or usage guidance reduces completeness.

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 no parameters (100% coverage by default). The description does not need to add parameter details. It correctly implies no inputs needed, which is sufficient.

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 verb ('list') and resource ('registered Vivado toolchains'), and specifies the context ('available to stdio workflows'). It distinguishes itself from siblings like register_toolchain_path and remove_registered_toolchain, which have different verbs and purposes.

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 when to use this tool: to view available toolchains before using them in workflows. However, it does not explicitly say when not to use it, nor does it mention alternatives like list_public_methods or other list tools. The guidance is adequate but lacks exclusions or comparison to siblings.

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