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, implying a write/mutation operation, but doesn't clarify permissions needed, whether the addition is reversible, potential side effects, or error conditions. For a mutation tool with zero annotation coverage, this leaves significant gaps in understanding its behavior.

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 front-loads the core action and resource. There's no wasted verbiage, and it directly communicates the tool's function without redundancy. Every word earns its place, 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?

For a mutation tool with 5 parameters, no annotations, and no output schema, the description is incomplete. It doesn't address behavioral aspects like success/failure responses, idempotency, or integration with other tools (e.g., how it relates to 'create_page'). The agent lacks sufficient context to use this tool effectively beyond basic parameter filling.

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 'grid layout', which hints at the 'columns' parameter, but doesn't add meaningful semantics beyond what the schema already provides. With 100% schema description coverage, the baseline is 3, as the schema fully documents all parameters (page_id, heading, images, columns, lightbox). The description doesn't compensate with additional context like format examples or constraints.

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') and resource ('image gallery section with grid layout'), making the purpose evident. It distinguishes itself from siblings like 'add_contact' or 'add_hero' by specifying the type of content being added. However, it doesn't explicitly differentiate from other content-adding tools in terms of when to choose a gallery over alternatives.

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 like 'add_features' or 'add_team'. It lacks context about prerequisites (e.g., needing an existing page), exclusions, or comparisons with sibling tools. The agent must infer usage from the tool name and parameters alone.

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