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

With no annotations provided, the description carries the full burden. It discloses that the tool fetches and returns data (implying read-only behavior) and specifies the structured output format, which is helpful. However, it doesn't mention potential limitations like authentication needs, rate limits, or error conditions, leaving some behavioral aspects unclear.

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 front-loaded with the core action and output, followed by a brief usage tip. Both sentences earn their place by clearly stating what the tool does and when to use it, with no redundant or vague language. It's efficiently structured for quick understanding.

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's moderate complexity (fetching and summarizing a diagram), no annotations, and no output schema, the description does well by specifying the return content. However, it could be more complete by detailing the exact structure of the summary or potential errors, though the lack of output schema means some gaps are inherent.

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 input schema has 100% coverage for its single parameter (diagram_id), so the baseline is 3. The description adds value by contextualizing the parameter as referring to a 'saved diagram to summarise,' reinforcing its purpose. However, it doesn't provide additional details like format examples or constraints beyond what the schema already covers.

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 specific action ('fetch a saved CloudForge diagram and return a structured summary') and distinguishes it from siblings by specifying what it returns (resource count by category, most-connected components, cloud provider, and Mermaid diagram). It uses precise verbs and identifies the exact resource being operated on.

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 clear context for when to use this tool ('ideal for quickly understanding an architecture'), which implies it's for analysis rather than creation or modification. However, it doesn't explicitly state when not to use it or name specific alternatives among the sibling tools, though the context suggests it's distinct from operations like delete_diagram or generate_terraform.

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