ruvds_list_templates

List available VM templates from marketplace and snapshots to obtain template IDs for server creation.

Instructions

List templates (marketplace, snapshots). Use template_id (UUID) in ruvds_create_server instead of os_id if needed.

Input Schema

NameRequiredDescriptionDefault

No arguments

Behavior2/5

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

No annotations provided. Description implies read-only ('List') but does not explicitly state behavioral traits such as read-only nature, authentication requirements, or pagination. With no annotations, the description carries full burden and falls short.

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

Conciseness5/5

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

Two-sentence description, front-loaded with purpose, followed by usage tip. Every sentence adds value with no redundancy.

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

Completeness4/5

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

Given low complexity (0 param, no output schema), description covers listing templates and how to use the result. Lacks mention of returned fields, but sufficient for agent to infer basic list behavior.

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

Parameters4/5

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

No parameters defined; schema coverage is 100%. Baseline for 0 parameters is 4, and description adds no further parameter semantics needed.

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

Purpose5/5

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

Description clearly states verb 'List' and resource 'templates (marketplace, snapshots)', distinguishing from sibling tools like ruvds_list_os. It provides specific resource type and context for usage.

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

Usage Guidelines5/5

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

Explicitly states when to use: to obtain template_id for ruvds_create_server instead of os_id. This provides clear guidance and differentiates from listing OS options.

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