create_data_source

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

With no annotations and only a generic description, the behavioral traits are absent. The agent cannot infer side effects, required permissions, or whether this is a mutation—essential for a creation tool.

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 sentence, which is concise but under-informative. It lacks the detail that would make it genuinely helpful, striking a balance between brevity and completeness.

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 the tool being simple (0 params, no output schema), the description fails to provide context about what a data source is or how it integrates with other tools. Given the many siblings, more context is needed.

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 input schema has zero parameters, and schema description coverage is 100%. There is nothing to explain beyond what the schema provides, so the description is adequate.

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 'Create a data source' states the action and resource, distinguishing it from sibling tools like list_data_sources, get_data_source, etc. However, it lacks specificity about what a 'data source' is or what the creation entails, making it only minimally clear.

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 such as test_data_source or update_data_source. The description offers no context about prerequisites or scenarios, so agents lack direction.

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