snowflake_clone_schema

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

No annotations are provided, so the description carries the full burden. It discloses the 'zero-copy' property, which is a useful behavioral trait for Snowflake cloning. However, it does not describe any side effects (e.g., whether the source remains fully accessible), permissions required, or reversibility. For a schema-level creation operation, this is thin.

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 one short sentence, which is concise, but it is under-specified rather than efficiently complete. It omits essential context that should be included for a tool with multiple parameters and no other documentation. Simplicity is not an asset when key information is missing.

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 has 3 parameters, 0% schema coverage, no annotations, and an output schema that is not referenced in the description, the description is far from complete. It does not address parameter usage, expected return, or any operational details an agent would need to call it correctly. This is inadequate.

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 says nothing about the parameters. It does not explain what 'source_schema' vs 'target_schema' mean, nor how the optional 'database' parameter interacts. An agent must guess the semantics from parameter names alone, which is insufficient for a multi-parameter tool.

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 states a clear action ('Create') and object ('clone of a schema'), and adds 'zero-copy' as a characteristic. However, it does not differentiate from sibling clone tools (e.g., snowflake_clone_table, snowflake_clone_database) beyond the word 'schema', which is already in the tool name. It essentially restates the name with minor elaboration.

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 alternatives. With siblings like snowflake_clone_table and snowflake_clone_database present, an agent has no textual clues to decide which clone tool is appropriate for a given task. There is no mention of context, exclusions, or alternative routes.

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