e2e_database_action

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

No annotations are provided, so the description carries the full burden. It says nothing about permissions required, whether stop is destructive or data-preserving, whether restart causes downtime, or whether the action is synchronous or asynchronous. For a mutation tool with zero annotation coverage this is a significant gap.

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 that names the verb, resource, and valid actions with zero filler. It is appropriately sized for the operation, though it could have spent a clause on behavioral caveats instead of being quite so terse.

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 mutation tool with no annotations and no output schema, the description leaves real gaps: permissions, downtime/reversibility of stop and restart, and the roles of the optional location and project_id parameters are all unaddressed. It is minimally adequate but not complete for a lifecycle-changing operation.

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 100%, so all four parameters are already documented, and the enum for 'action' is fully specified in the schema. The description's listing of start/stop/restart simply repeats the enum, adding no syntax or constraint detail beyond the schema, so baseline 3 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?

States a specific verb ('Execute a control action') plus the resource ('managed database cluster') and enumerates the three supported actions. This distinguishes it from sibling action tools like e2e_node_action and e2e_tir_notebook_action by resource type, though it never names them 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?

There is no explicit when-to-use guidance, no prerequisites, and no mention of alternatives or when not to use it. The agent must infer that this is for lifecycle control of database clusters rather than any of the many other action tools.

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