Close gdb

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

Without annotations, the description must disclose behavioral traits. It acknowledges destruction ('terminate and remove'), but omits details like side effects on running processes, required auth, or error handling (e.g., closing an already-closed session).

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 too brief; it lacks critical information that would justify its length. While concise, it under-specifies the tool's behavior and parameters.

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?

Despite a simple signature (1 param, no nested objects), the description fails to cover prerequisites (session must exist), return values (though output schema exists), or side effects, leaving the agent under-informed.

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?

With 0% schema coverage, the description must explain the sole parameter ('session_id'). It does not mention what it is, how to obtain it, or its format, providing no value beyond the schema.

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 ('terminate and remove') and the resource ('a gdb session'). It effectively distinguishes itself from siblings like gdb_spawn (create), gdb_exec (run commands), and gdb_interrupt (halt execution).

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?

No guidance is provided on when to use this tool versus alternatives, such as when to close versus interrupt a session, or whether multiple closes are safe.

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