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

No annotations are provided, so the description carries the full burden of behavioral disclosure. It states 'Get' implying a read operation, but does not confirm idempotency, error behavior for invalid references, or whether this triggers any side effects in the debug 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?

Single sentence, front-loaded with the verb, and appropriately sized for a simple getter tool. However, given zero annotations and no output schema, the brevity leaves critical workflow context undocumented.

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?

As part of a debugger toolset, the description fails to explain the relationship to the 'scopes' tool (required to obtain the variablesReference) or what the return structure looks like. Relies entirely on schema for parameter docs but provides no guidance for the return values or error cases.

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 the schema already documents both parameters adequately. The description adds the phrase 'variable container' which loosely maps to 'parent variable' in the schema, but does not add significant semantic detail or usage examples beyond what the schema provides.

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?

Clear verb ('Get') and resource ('variables') with contextual narrowing ('from a scope or variable container'). However, it does not explicitly distinguish from sibling tools like 'scopes' or clarify the debugging workflow context implied by the server toolset.

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?

Provides no guidance on when to use this tool versus siblings, nor does it explain prerequisites (e.g., that 'variablesReference' must be obtained from 'scopes' or parent variables first). The schema parameter description mentions the source, but the main description lacks workflow guidance.

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