⚠️ CREATES FILE: Create new empty SQLite DB; fails if file exists.

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

With no annotations, the description carries the full transparency burden. It discloses the file-creation side effect via 'CREATES FILE' and the failure condition if the file exists. It does not mention permissions, parent directory creation, or post-creation behavior, but for a simple create operation it is reasonably transparent.

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 one short, front-loaded sentence with a warning flag. Every word adds value: creation, emptiness, SQLite nature, and failure condition. No redundant phrasing.

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 one-parameter creation tool, the description covers the essential behavior and main failure mode. It does not mention what happens on success (e.g., return value or auto-open), but there is no output schema and the missing details are low-stakes. Slightly more context could be added, but the current description is adequate.

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 has a single 'path' parameter with zero description coverage. The description implies 'path' is the file path to create, but it does not explicitly state this or add format/behavioral details beyond what the schema shows. Meaning is inferable but not explicitly documented.

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?

Tautological: description restates name/title.

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 failure condition ('fails if file exists') implies when not to use it, but no explicit alternatives are mentioned, such as using open_database for existing files or backup_database for copying. Usage context is implied rather than explicitly contrasted with sibling tools.

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