sqlite_list_tables

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

No annotations are provided, so the description carries the full burden. It indicates a read-only listing operation but does not disclose details like error handling, whether system tables are included, or output format (though an output schema exists). It is minimally adequate but not rich.

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 with no redundant words. It is front-loaded with the verb 'List' and directly states the target, making it concise and well-structured.

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 tool's simplicity (one parameter, clear action, and output schema present), the description is sufficient for basic usage. It could mention edge cases like views or system tables, but that is not essential and would add noise.

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 schema fully documents the single parameter 'database' as 'Path to the .db or .sqlite file.' The description adds no extra semantic detail, so baseline 3 applies per the rubric.

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 ('List') and the resource ('all tables in a SQLite database file'), making its purpose unambiguous. It is specific enough to distinguish from sibling tools like sqlite_table_info (which lists column details) and sqlite_schema (which shows schema objects).

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 gives clear context: it lists tables in a SQLite file, which is sufficient to know when to use it. However, it does not explicitly mention alternatives or when not to use it, such as preferring sqlite_table_info for column details, so it is not a full 5.

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