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. 'Add a FAQ section' implies a write/mutation operation, but it doesn't specify permissions required, whether it's idempotent, how errors are handled, or what the output looks like (e.g., success confirmation or new element ID). This leaves significant gaps for an agent to understand the tool's behavior beyond basic intent.

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 a single, efficient sentence ('Add a FAQ section') that is front-loaded and wastes no words. It directly conveys the core action without unnecessary elaboration, making it easy to parse quickly.

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 complexity of a mutation tool with 3 parameters, no annotations, and no output schema, the description is incomplete. It doesn't explain the return value, error conditions, or integration with other tools (e.g., how this relates to 'get_page_structure' or 'update_element'). For a tool that modifies content, more context is needed to use it effectively.

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 input schema fully documents parameters ('page_id', 'heading', 'faqs') with descriptions. The description adds no additional meaning beyond what's in the schema (e.g., no examples, formatting rules, or constraints), meeting the baseline score of 3 for high schema coverage without extra value.

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 FAQ section' clearly states the verb ('Add') and resource ('FAQ section'), but it's vague about what this entails compared to siblings like 'add_contact' or 'add_testimonial'. It doesn't specify whether this creates a new page element, modifies an existing one, or how it integrates with the page structure, making it less distinct from other 'add_' tools.

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?

No guidance is provided on when to use this tool versus alternatives. For example, it doesn't mention prerequisites like needing an existing page (implied by 'page_id' but not stated), or how it differs from other content-adding tools in the sibling list. The description lacks context about typical use cases or exclusions.

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