get_submix_effect_chain

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

Annotations already declare readOnly, idempotent and non-destructive. The description adds genuine behavioral context beyond them: the chain is returned in slot order, empty slots are represented as 'None', and chain_length is provided. Return structure is also described since no output schema exists.

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 tightly written sentences: the verb and resource are front-loaded, followed by the return shape. Every clause carries information (ordering, empty-slot sentinel, length field) and nothing is padded.

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?

With no output schema, the description supplies the full return contract (submix_path, effects array, chain_length) and the read-only framing. Nothing needed to call this correctly is missing.

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 100% for the single submix_path parameter, including a concrete example path. The description adds no syntax or format detail beyond the schema, so the baseline 3 is appropriate.

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?

States a specific verb (Read) and resource (the effect chain of a USoundSubmix asset), plus the ordering guarantee and per-slot content (name, class, path, 'None' for empty). An agent can distinguish this read tool from the write-oriented add_submix_effect_to_chain without opening either schema.

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?

It explicitly names the alternative sibling add_submix_effect_to_chain and its relation (appends to the chain), making the read-vs-write split clear. It stops short of stating when-to-use conditions or prerequisites, but the context is unambiguous.

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