execute_insert

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

With no annotations, the description carries the transparency burden. It discloses a behavioral trait: the function returns the inserted row ID 'if available,' hinting at possible unavailability. However, it does not state side effects (e.g., data mutation), permission needs, or error conditions, leaving gaps for a write operation.

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 two concise sentences, front-loading the core action. Every word contributes: 'Insert data into a table' states the function, and the second sentence provides a useful return detail. No redundancy or fluff.

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 simple tool with a clear schema, the description covers the action and return value. However, with no output schema, it omits when the row ID might be unavailable and gives no hint about constraints or error behavior. It is close to complete but lacks a few contextual edges.

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%, so the parameters are already well documented. The description adds no extra meaning beyond the schema—it doesn't explain how the 'data' object should be structured or any special tableName considerations. Baseline 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 states a specific verb and resource: 'Insert data into a table.' This clearly distinguishes the tool from siblings like execute_query and execute_update by focusing on the insert operation. Adding the return behavior ('Returns the inserted row ID if available') further clarifies purpose.

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?

There is no guidance on when to use this tool versus alternatives. It does not mention when to prefer insert over update/query, nor does it state conditions like table existence or constraint requirements. The description only states what the tool does, not when to use it.

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