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

Annotations already cover readOnly/safe profile; the description adds valuable behavior detail—the return shape (ctx + cfg), the expected workflow (edit values, keep structure), and how the output feeds save_page_content. It doesn't cover error cases for unknown section types, but the added context is well beyond the annotations.

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?

Front-loaded with the core action and return value, then usage. Slightly repetitive in the second paragraph about replacing text values, but every sentence carries practical guidance.

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?

The tool is simple (1 param, read-only, no output schema) and the description fully explains the return structure and how to use it. Minor gap around invalid section type behavior, but otherwise complete for the agent's needs.

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 coverage is 100% and already documents sectionType with examples, so the description adds no syntax or format detail for the single parameter. 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 and resource (get default content/config structure for a section type) and clearly distinguishes itself from siblings like list_section_types and save_section_content by naming what it returns (ctx and cfg).

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?

Explicitly states when to use it ('before creating a section') and ties it to the follow-up action (modify and pass to save_page_content), giving the agent a clear workflow.

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