add_model

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

No annotations are provided, so the description carries full burden. It only states 'add' but does not disclose write behavior, side effects (e.g., persistence, conflicts with existing configs), or required permissions. For a mutation tool, this is insufficient.

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 very short (one sentence), which might be considered concise, but it sacrifices necessary detail. It does not fully earn its place given the lack of content.

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 tool with no annotations, no output schema, and a complex nested parameter (config with 10 subfields), the description provides no additional context about return values, required server state, or relationships between parameters. The description is incomplete.

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% per context, so baseline is 3. The description adds no meaning beyond the schema; it repeats 'Add a new model configuration' without explaining how parameters like metrics, no_mmap, or threads affect the operation.

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 'Add a new model configuration' uses a verb ('Add') and resource ('model configuration') but lacks specificity about what constitutes a model configuration and how it differs from updating or validating. It is clear in a minimal sense but vague.

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?

No guidance on when to use this tool versus sibling tools like update_model_config or validate_config. No prerequisites or typical context (e.g., whether server must be running) are mentioned.

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