get_assembly_features

Retrieve all assembly features including mates and mate connectors along with their current state to inspect and debug assembly issues.

Instructions

Get all features (mates, mate connectors, etc.) from an assembly with their current state (OK, ERROR, SUPPRESSED). Useful for inspecting existing mates and debugging assembly issues.

Behavior3/5

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

No annotations are provided, so the description carries the burden. It implies read-only behavior but does not mention auth needs, rate limits, side effects, or return format. This is adequate for a simple query but lacks explicit behavioral disclosure.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Two concise sentences front-load the purpose and usage. Every word adds value, with no redundancy or filler.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness4/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

The description covers what the tool returns (features with states) and its use case (debugging). It is complete for a simple query tool with three required params and no output schema, though it could mention error handling or result format.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 100%, so the schema already documents each parameter. The description does not add additional meaning beyond the schema, meeting the baseline but not exceeding it.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the verb 'Get', resource 'assembly features', and provides examples like mates and mate connectors. It differentiates from siblings by specifying assembly context and including state information, making the purpose unmistakable.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines4/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description suggests usage for inspecting mates and debugging assemblies, providing clear context. However, it does not explicitly compare to alternatives like 'get_features' or specify when not to use it, which slightly limits full guidance.

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