add_filament_spool

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

With no annotations, the description carries the full burden for behavioral disclosure. It mentions location auto-creation and defaults, but omits side effects, error conditions, permission requirements, or reversibility, leaving key behavioral traits undisclosed for a mutation 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 concise and well-structured, with a one-line purpose followed by parameter bullets. Every sentence contributes valuable information without 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?

The description covers purpose and all parameters, but lacks explicit usage guidance and deeper behavioral context. Given the output schema exists and no annotations, it is adequate but leaves gaps in when-to-use and side-effect awareness.

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 Args section documents every parameter with meaningful semantics beyond the schema's bare titles, compensating for 0% schema description coverage. Each parameter gets a clear explanation of its purpose and defaults.

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 adds new filament spool(s) linked to an existing material blueprint, with a specific verb and resource. However, it does not differentiate from the sibling quick_add_spool, which likely serves a similar purpose.

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 usage context by requiring an existing material blueprint and noting that locations are created if new. It does not explicitly state when to use this tool versus alternatives like quick_add_spool or add_inventory_item.

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