add_paragraph

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It adds meaningful behavior context by naming parameter semantics: size is points, color is hex, align has an enumerated set, and spacing is in centimeters. The word "Append" also signals that the paragraph is added at the end of the document. It does not disclose error behavior or invalid style handling, but it goes well beyond the bare schema.

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 compact and front-loaded, with the core action stated first. Every clause adds value: the heading tip is practical, and the parameter annotations are packed into two sentences without repetition or filler. It is efficient while being informative.

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 the 11 parameters, 0% schema coverage, and no annotations, the description covers most of the information an agent needs to call the tool correctly: units, formats, allowed values, and optional style behavior. It lacks explicit guidance on font/italic semantics and does not name sibling alternatives for selection, but the core calling requirements are well covered.

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, and it does for the most important parameters. It clarifies units for size and spacing, hex format for color, allowed align values, and the role of the style parameter. It does not explain font or italic, but these are reasonably inferable from their names, and text/doc_id are self-evident.

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 opens with a specific verb and resource: "Append a styled paragraph to a Writer doc." This clearly distinguishes the tool from siblings like add_textbox, add_list, and insert_text by stating it adds a styled paragraph to a document. The parenthetical "workhorse" and heading guidance further reinforce its intended role.

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 implies common use cases, such as using a large bold size for headings, which gives practical formatting guidance. However, it does not explicitly state when to choose this tool over alternatives like add_textbox or insert_text, nor does it mention any exclusions. The usage context is implied rather than explicit.

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