get_database_info

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

No annotations are provided, so the description carries the full behavioral burden, and it discloses nothing about safety: it never states the call is read-only, or whether it requires auth, hits a database that may be locked, or has any cost. The 'Long-term query database' phrasing implies a diagnostic read, but nothing is explicitly guaranteed.

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 compact clause that front-loads the three returned data points with no filler. It is a noun fragment rather than a full sentence, but every word earns its place.

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?

With an output schema present, return-value details are already covered, and with zero parameters there is no input contract to explain. The only missing piece is sibling differentiation in a tool set crowded with similar info-gathering calls.

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 tool takes zero parameters and the schema is trivially complete, so there is nothing for the description to compensate for. Baseline 4 applies for a no-argument tool.

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 names the exact payload it returns — long-term query database size, query count, and SQLite version — which is more specific than the bare name. However, it does not differentiate itself from adjacent informational siblings such as get_stats, get_version, get_system_info, or server_info, so an agent must guess which info tool to pick.

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 call this versus get_stats, get_version, or get_system_info, despite these siblings clearly overlapping in the 'tell me about the server/database' space. The description only states content, never context or exclusions.

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