find_missing_schemas

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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states the tool finds missing schemas but does not describe how it operates—e.g., whether it performs a read-only comparison, requires authentication, has rate limits, or returns results in a specific format. For a tool with zero annotation coverage, this lack of detail is a significant gap.

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 unnecessary words. It directly states what the tool does, making it easy to understand at a glance, with zero waste or redundancy.

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 complexity of comparing registries, lack of annotations, no output schema, and low schema description coverage, the description is incomplete. It does not address behavioral aspects like safety, performance, or result format, nor does it provide usage context or parameter details. This leaves significant gaps for an AI agent to invoke the tool correctly.

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 implies parameters for 'source_registry' and 'target_registry' but does not add meaning beyond what the input schema provides. With 0% schema description coverage, the schema titles ('Source Registry', 'Target Registry', 'Context') are basic, and the description does not explain what these parameters represent (e.g., registry names, URLs) or the optional 'context' parameter's purpose. It compensates minimally, aligning with the baseline for low coverage.

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 tool's purpose: 'Find schemas that exist in source registry but not in target registry.' It specifies the verb ('find') and resources ('schemas'), and distinguishes the operation as a comparison between two registries. However, it does not explicitly differentiate from sibling tools like 'compare_registries' or 'bulk_schema_migration', which may have overlapping functions, preventing 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 lacks information on prerequisites, such as whether registries need to be connected or accessible, and does not mention sibling tools like 'compare_registries' or 'bulk_schema_migration' that might serve similar purposes. This omission leaves the agent without context for tool selection.

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