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

With no annotations provided, the description carries the full behavioral burden and does well by enumerating exactly what is checked: syntax validity, no diamonds, no taskboxes, root circle, and branch rectangles. It implies a non-mutating validation operation and gives the agent concrete expectations, though it does not describe the success/error response format.

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?

Two focused sentences, with the primary purpose front-loaded and the validation criteria compactly listed. Every sentence adds value, with no filler or repetition of schema content.

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 simple one-parameter validation tool, the description provides sufficient context: the exact validation rules and the recommended position in the workflow. The only notable gap is the lack of information about the tool's return value, but the tool's simplicity and clear purpose keep this from being a major omission.

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%, and the single 'code' parameter is already well-described in the schema. The description does not add parameter-level detail such as formatting or examples, so the baseline score of 3 is appropriate.

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?

States a specific verb ('Validate'), resource ('FlowZap Code'), and scope ('specifically for Mind Map diagrams'). It lists concrete validation criteria, and distinguishes itself from the generic sibling flowzap_validate by narrowing to mind map readiness.

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?

Explicitly directs the agent to use this tool before flowzap_mindmap_approve and flowzap_mindmap_create_playground, establishing clear workflow sequencing. The phrase 'specifically for Mind Map diagrams' communicates when this variant is preferred over the general validator.

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