create_roof_truss

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

No annotations are provided, so description carries full burden. It states trusses include proper web patterns, angled members, and realistic connections, giving some behavioral insight. However, it lacks details on side effects, resource usage, or permissions. For a creation tool, it is moderately transparent but could be more thorough.

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?

Two sentences: first states purpose and supported types, second provides a resource reference. Every sentence is informative and necessary, with no fluff or redundancy.

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 9 parameters all with schema descriptions and no output schema, the description covers the core purpose and key constraints. It refers to a resource for detailed guidance. While it could elaborate on output format or lifecycle, it is reasonably complete for a specialized creation 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 100%, so baseline is 3. Description adds value by detailing span ranges for each truss type (e.g., king post up to 26'), which is not in schema. It also references a resource for guidance, enhancing parameter understanding beyond schema defaults and enums.

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?

Description explicitly states tool creates engineered roof trusses with accurate geometry. It specifies supported types (king post up to 26', fink 20-60') and contrasts with generic geometry tools among siblings, making its purpose distinct and clear.

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?

Description implies usage scenarios by specifying span ranges for each truss type (king post simple up to 26', fink common 20-60'). It references a resource for detailed guidance but does not explicitly state when to use versus alternatives or when not to use. Context of sibling tools suggests specialization.

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