✓ SAFE: Open existing SQLite DB and set current context.

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. It simply restates the action without explaining side effects, error behavior (e.g., nonexistent path), or whether the tool modifies global state. The '✓ SAFE' prefix is a brief safety hint but adds little concrete behavioral context.

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 short sentence with no wasted words, making it concise. However, it is identical to the title, which slightly reduces its added value, but the structure itself is clean and front-loaded.

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?

The tool has a simple interface (one parameter, no output schema), but the description leaves out important context such as what 'current context' means, how it interacts with other tools, and what the expected result is. Given the low structural richness, a few additional clarifying details would greatly improve completeness.

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 0%, and the description does not mention the 'path' parameter at all. Although the parameter name is self-explanatory, there is no guidance on accepted path formats, relative vs. absolute paths, or whether the file must already exist. The description fails to compensate for the missing schema documentation.

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 description implies usage as a prerequisite step before querying or modifying a database, but it does not explicitly state when to use this tool versus alternatives like create_database or list_databases. No exclusions or practical guidance is provided.

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