tables_db_create_point_column

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

No annotations are provided, so the description carries full burden. It states 'Create' which implies a write/mutation operation, but doesn't disclose behavioral traits such as permissions required, whether it's idempotent, error conditions, or what happens on success/failure. The description lacks context on side effects or system behavior beyond the basic action.

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, clear sentence with zero waste. It's front-loaded with the core action and resource, making it easy to parse quickly. Every word earns its place without 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 (mutation tool with 5 parameters, no annotations, no output schema), the description is incomplete. It doesn't cover what the tool returns, error handling, or practical usage context. For a creation tool in a database system, more behavioral and contextual information would be needed for adequate agent guidance.

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%, providing good documentation for all parameters. The description adds no additional parameter semantics beyond what's in the schema (e.g., it doesn't explain 'geometric point' further or provide examples). Baseline score of 3 is appropriate since the schema does the heavy lifting.

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 ('Create') and resource ('geometric point column'), which is specific and distinguishes it from general table creation tools. However, it doesn't explicitly differentiate from other column creation siblings like 'tables_db_create_boolean_column' or 'tables_db_create_polygon_column' beyond the 'point' qualifier.

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. The description doesn't mention prerequisites (e.g., needing an existing table), exclusions, or comparisons to other column types or sibling tools like 'tables_db_create_line_column' or 'tables_db_update_point_column'.

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