validate_mpn_consistency

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

With no annotations, the description carries full responsibility for disclosing behavior. It states 'Detect' suggesting a read-only operation, but doesn't describe what the tool returns, how it handles the 'path' parameter, or whether any side effects occur. The description provides minimal behavioral insight beyond the obvious.

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 concise sentence with no unnecessary words. It is front-loaded with the action verb, but the extreme brevity borders on under-specification.

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?

Despite having an output schema, the description is incomplete for a validation tool with one undocumented parameter. It lacks essential context about the input path, the structure of the conflict detection, and how the result is presented. The description is too minimal to be fully actionable.

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 0% and the description does not mention the sole parameter 'path'. The agent is left completely uninformed about what 'path' refers to (e.g., file path, document ID, library path) or how to provide it.

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 uses a specific verb ('Detect') and names the resource ('one MPN') with the specific concern ('conflicting manufacturer/value/pattern metadata'), making the core purpose clear. However, it doesn't distinguish this tool from the sibling validator 'validate_value_pattern_consistency' or explain what 'one MPN' refers to in context.

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 the many sibling validation tools (e.g., validate_value_pattern_consistency, validate_library_component). The description gives no context about appropriate use cases or exclusions.

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