validate_archimate_model

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

With no annotations provided, the description carries full burden but offers minimal behavioral insight. It states validation occurs 'against the ArchiMate 3.2 specification' but doesn't disclose what validation entails (e.g., syntax checks, semantic rules, error reporting), whether it's read-only (implied but not stated), or performance considerations (e.g., handling large arrays). This leaves significant gaps for a tool with two required parameters.

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 purpose without fluff. Every word contributes directly to understanding the tool's function (validate, ArchiMate elements/relationships, specification version). It avoids redundancy and is appropriately sized for the complexity.

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 validation tool with no annotations and no output schema, the description is insufficient. It doesn't explain what constitutes valid/invalid input, how results are returned (e.g., error messages, status codes), or edge cases (e.g., empty arrays). Given the tool's potential complexity (validating architectural models), more context on behavior and outputs is needed for effective use.

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%, with clear descriptions for 'elements' and 'relationships' arrays. The description adds no additional parameter semantics beyond implying validation scope, but doesn't detail format expectations (e.g., valid 'type' values) or validation rules. Given high schema coverage, the baseline score of 3 is appropriate, as the description doesn't compensate but doesn't detract either.

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 ('validate') and target ('ArchiMate elements and relationships') with specific reference to the ArchiMate 3.2 specification. It distinguishes this from siblings like export, generate, and list tools by focusing on validation. However, it doesn't explicitly contrast with potential validation alternatives (e.g., schema-based vs. rule-based validation), keeping it from a perfect score.

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. It doesn't mention prerequisites (e.g., needing valid element/relationship data), exclusions (e.g., not for partial models), or compare with sibling tools like list_archimate_elements for checking existence. Usage is implied only through the tool name and description, lacking explicit context.

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