chatlab_execute_sql

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

The description labels the tool as 'readonly', which is a key behavioral trait. However, no other behaviors (e.g., limits, error handling, authentication needs) are disclosed. With no annotations provided, the description carries the full burden but does little beyond the readonly hint.

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?

A single, efficient sentence with no wasted words. Could benefit from a slightly more structured approach (e.g., bullet points) but remains appropriately concise.

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 no output schema and 0% schema coverage, the description fails to explain return format, error behavior, or the relationship between sessionId and the session database. For a read-only SQL tool, more context is needed for correct invocation.

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 0% description coverage, and the tool description does not add any parameter-level meaning beyond the field names 'sessionId' and 'sql'. The agent lacks guidance on what constitutes a valid sessionId or the expected SQL syntax.

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 'Execute readonly SQL against a ChatLab session database', specifying the verb (execute), resource (SQL), and scope (readonly). This distinguishes it from sibling tools like chatlab_request or chatlab_get_messages.

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 explicit guidance on when to use this tool vs alternatives, such as when to prefer SQL over other data access methods. Usage is implied but not clarified.

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