tables_db_create_string_column

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

With no annotations provided, the description carries the full burden of behavioral disclosure but offers minimal information. 'Create' implies a write/mutation operation, but the description doesn't address permissions needed, whether this action is reversible, potential side effects, or error conditions. It lacks context about what 'creating a column' entails operationally 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 extremely concise at just three words, with zero wasted language. It's front-loaded with the essential action and resource. While arguably too brief for a mutation tool with no annotations, it achieves maximum efficiency within its limited scope.

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?

For a mutation tool with 8 parameters, no annotations, and no output schema, the description is inadequate. It doesn't explain what happens after creation, potential constraints, or how this integrates with the broader database system. The agent must rely entirely on the input schema for operational details, leaving significant contextual gaps.

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 adds no parameter information beyond what's already in the schema (which has 100% coverage). It doesn't explain relationships between parameters (e.g., that 'default' cannot be set when 'required' is true), provide examples, or clarify the meaning of 'key' versus other identifiers. With complete schema documentation, the baseline score of 3 is appropriate.

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 string column' clearly states the verb ('Create') and resource ('string column'), making the purpose immediately understandable. It distinguishes itself from sibling tools like 'tables_db_create_boolean_column' by specifying the column type, though it doesn't explicitly mention the database/table context which is implied by the tool name.

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 doesn't mention prerequisites (e.g., needing an existing database and table), compare it to other column-creation tools, or indicate when a string column is appropriate versus other data types like integer or boolean columns.

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