list_supported_languages

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 only states the tool lists languages but discloses nothing about side effects (e.g., it is read-only, non-destructive), data freshness, or performance. For a simple list, this is a notable 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?

The description is a single sentence, which is maximally concise. It is front-loaded with the verb 'List' to immediately convey the action. Every word earns its place, with no filler or redundancy.

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 tool's simplicity (no parameters, no output schema), the description is minimally adequate. However, it lacks details on the return format or what 'metadata' includes, which would help an agent understand the output. It is complete enough for basic usage but not rich.

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 has zero parameters and schema coverage is 100% (empty). Per guidelines, baseline for 0 params is 4. The description does not need to add parameter information since there are none, so this score is appropriate.

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 'List all supported debugging languages with metadata' clearly states the action (list), the resource (supported debugging languages), and that metadata is included. It distinguishes from sibling tools, which are all action-oriented debugging operations, making the purpose unambiguous.

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?

The description provides no guidance on when to use this tool versus alternatives. With 20 sibling tools like 'start_debugging' or 'create_debug_session', it would be helpful to mention that this tool is useful before initiating debugging sessions to discover available languages, but no such context is given.

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