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

No annotations are provided, so the description carries full burden for behavioral disclosure. 'Add' implies a write/mutation operation, but the description doesn't specify whether this requires specific permissions, what happens if the page_id doesn't exist, whether the CTA is appended or inserted at a specific position, or what the response looks like. For a mutation tool with zero annotation coverage, this is a significant gap in transparency.

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 maximally concise at just 5 words ('Add a call-to-action section'), with zero wasted words. It's front-loaded with the core action and resource, making it immediately scannable and understandable. Every word earns its place in conveying the essential purpose.

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?

For a mutation tool with 5 parameters, no annotations, and no output schema, the description is insufficiently complete. It doesn't address behavioral aspects like error conditions, positioning within pages, visual characteristics, or how this integrates with the broader system of sibling tools. The agent lacks context about what 'success' looks like or potential pitfalls.

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 100%, so the schema already documents all 5 parameters with basic descriptions. The description adds no additional parameter semantics beyond what's in the schema - it doesn't explain relationships between parameters (e.g., how heading and subheading work together), format requirements, or constraints. The baseline of 3 is appropriate when the schema does the heavy lifting.

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 'Add a call-to-action section' clearly states the verb ('Add') and resource ('call-to-action section'), making the purpose immediately understandable. However, it doesn't differentiate from sibling tools like 'add_hero' or 'add_features' which also add sections, leaving room for confusion about what specifically distinguishes a CTA section from other section types.

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 provides no guidance on when to use this tool versus alternatives. With many sibling tools like 'add_hero', 'add_features', and 'insert_element', there's no indication of whether this is for specific page types, contexts, or how it relates to other section-adding tools. The agent must infer usage from the tool name alone.

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