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 states the tool adds a section but doesn't cover critical aspects: whether this is a mutation (likely, given 'add'), what permissions are required, if it's idempotent, how errors are handled, or what the output looks like. For a tool that presumably modifies content, this lack of transparency is a significant gap.

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 that directly states the tool's function without fluff. It's front-loaded with the core action ('Add a pricing section') and includes the key constraint ('with 2-3 pricing tiers'), making it easy to parse quickly. Every word serves a 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?

Given the tool likely performs a mutation (adding content) with no annotations and no output schema, the description is insufficient. It doesn't address behavioral risks, expected outcomes, or error conditions. For a tool with 4 parameters and complex nested structures in 'tiers', more context is needed to ensure safe and effective use by an AI agent.

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?

The description mentions '2-3 pricing tiers', which aligns with the 'tiers' parameter in the schema, but adds no further semantic context beyond what the 100% schema coverage already provides. It doesn't explain the relationship between parameters (e.g., that 'tiers' contains nested objects) or offer usage examples. With high schema coverage, the baseline is met but not exceeded.

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 ('Add a pricing section') and specifies the content ('with 2-3 pricing tiers'), making the purpose immediately understandable. It distinguishes from siblings like 'add_contact' or 'add_faq' by focusing on pricing tiers, though it doesn't explicitly contrast with similar tools like 'add_features' or 'add_hero' beyond the subject matter.

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. It doesn't mention prerequisites (e.g., needing a page created first), nor does it explain how it differs from other 'add_' tools like 'add_features' or 'add_cta' in context. The description is purely functional without contextual advice.

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