interpolate_profiles

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

With no annotations, the description must carry full burden. It explains that numeric values are interpolated and non-numeric values are taken from the nearer profile, but does not discuss side effects like file creation, overwrite behavior, or error conditions.

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 relatively concise with a clear first sentence. The param list at the end is helpful given no schema descriptions, but it is somewhat unstructured and could be formatted better.

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 annotations or output schema, the description is incomplete. It does not explain what the tool returns, any prerequisites, or error handling. For a tool with 7 parameters, this lacks completeness for an agent to use it correctly.

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 description coverage is 0%, so the description must compensate. It lists all 7 parameters but only explains 'factor' (0.0 gives A, 1.0 gives B). Other parameters like 'profile_a' and 'file_path' have no added meaning beyond the schema.

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 'Blend two PP3 profiles by linear interpolation,' specifying the verb (blend), resource (PP3 profiles), and method. This distinguishes it from siblings like 'compare_profiles' or 'create_profile_variant' which have different 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 says 'Useful for creating intermediate looks between two processing styles,' which implies the use case. However, it does not provide explicit when-not-to-use guidance or mention alternative tools for similar tasks.

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