db_status

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

No annotations are supplied, so the description must carry the behavioral burden. The word 'Check' implies a non-mutating read, but the description does not confirm it is safe/read-only, whether it hits the network, or whether results are cached; for a simple zero-argument status tool these gaps are minor but real.

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 front-loaded sentence naming the subject and the three things inspected, with no filler, hedging, or repetition. Nothing could be removed without losing information.

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 description enumerates the three facets of the response (status, safety tier, connection), which effectively tells the agent what it will learn even though no output schema exists. It falls short only on what the possible status values mean or how to interpret a degraded tier.

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 has an empty properties object, so there is nothing for the description to disambiguate beyond what the schema already establishes. Baseline for a parameterless tool applies.

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 pairs the specific verb 'Check' with three concrete resources: gateway status, active safety tier, and database connection. That clearly separates it from the sibling tools such as db_query and db_commit, which perform data operations rather than status inspection, though it never names those siblings explicitly.

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?

Usage is only implied: an agent can infer this is a pre-flight or diagnostic check to run before queries or commits, but the description never states when to prefer it or what to do with the result. No exclusions or alternatives are named among the eleven sibling tools.

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