add_paragraph_to_content

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

Without annotations, the description carries the burden. It indicates modification (append) and return of updated string, and mentions 'can be empty' for input. However, it lacks details on side effects, error handling, or ordering guarantees.

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 concise, uses a clear structure with Args and Returns sections, and every sentence adds value. No unnecessary text.

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 existence of an output schema (not shown), the return description is sufficient. However, the description could be more complete by explaining that the paragraph is appended as a new block, or addressing edge cases like invalid input.

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?

With 0% schema coverage, the description compensates by explaining both parameters: existing_content is 'current EditorJS JSON string (can be empty)' and text is 'paragraph text to append'. This adds meaning beyond names but lacks details like format constraints or allowed character limits.

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 action ('Append a paragraph') and the resource ('existing EditorJS content string'). It distinguishes itself from sibling tools that handle broader operations like creating lessons or building full content.

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 when to use (when wanting to add a paragraph to EditorJS content) but provides no explicit guidelines on when not to use or alternatives. No mention of prerequisites or context relative to siblings like build_lesson_content.

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