add_list

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

No annotations are present, so the description carries the full burden of behavioral disclosure. It does state the append behavior and the ordered/bulleted distinction, but it omits side effects, insertion location, relationship to doc_id, and any return behavior.

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 one concise, front-loaded sentence with no filler. It communicates the core operation and the key conditional behavior efficiently.

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?

This is a five-parameter tool with no annotations, no output schema, and no schema description coverage. The description is too thin to enable reliable invocation: it does not explain size/color semantics, where the list is appended, or what happens upon success.

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 clarifies 'items' via 'one string per item' and 'ordered' via 'if ordered=true', but it says nothing about doc_id, size, or color, leaving two required/three optional parameters underspecified.

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 verb 'Append' and the resource ('bulleted or numbered list'), with the detail that each string corresponds to an item. It does not explicitly differentiate this tool from siblings like add_paragraph or insert_text, so it misses the top score.

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?

There is no guidance about when to use add_list versus alternatives such as add_paragraph or insert_text, and no stated prerequisites or exclusions. The only usage hint is that ordered=true switches to a numbered list, which is a parameter detail rather than tool-selection guidance.

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