db.init

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

No annotations are provided, so the description carries full burden. It mentions the tool initializes tables but lacks details on behavioral traits like whether it's idempotent, requires specific permissions, destroys existing data, or handles errors. This is inadequate for a setup tool with zero annotation coverage.

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, efficient sentence that front-loads the purpose ('Initialize database tables') and adds necessary context ('run once on first setup'). Every word earns its place with no waste.

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 complexity of a database initialization tool with no annotations and no output schema, the description is incomplete. It doesn't explain what 'initialize' entails (e.g., creates tables, sets up schemas), potential side effects, or return values, leaving gaps for safe agent usage.

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?

There are 0 parameters, and schema description coverage is 100%, so no parameter documentation is needed. The description doesn't add param info, but that's acceptable here. Baseline is 4 for zero parameters, as it avoids unnecessary details.

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 ('Initialize') and resource ('database tables'), specifying it's for first-time setup. However, it doesn't explicitly differentiate from siblings like db.get_findings or db.save_finding, which are for querying/inserting data rather than schema setup.

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?

It provides clear context for usage ('run once on first setup'), which implies this is a one-time initialization tool. However, it doesn't explicitly state when not to use it or name alternatives, such as whether to re-run it after errors or if other tools handle schema updates.

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