get_trace_info

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 it returns metadata but does not explicitly confirm it is read-only, has no side effects, or mention permissions or error conditions. For a getter, 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 concise and front-loaded with the purpose. There is minor redundancy (mentioning metadata and then returning a Dict), but it remains short and focused.

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 zero-parameter getter, the description covers the return type and general purpose. However, it lacks detail on behavior when no trace exists, whether the operation is safe, and how it relates to sibling tools. The output schema is present, so return structure is partially covered, but edge-case context is missing.

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, so the schema is fully descriptive; the baseline is 4. The description adds context about return values but no parameter semantics are needed. It does not need to compensate for missing parameter info.

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 uses a specific verb ('Get') and a clear resource ('information about the current Langfuse trace and context'). It explicitly mentions metadata and context values for debugging, which distinguishes it from sibling tools that enable/set/reset test context. Not a tautology.

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 implies a debugging use case but provides no explicit guidance on when to use this tool versus alternatives, nor any exclusions. Siblings are set/reset tools, so the usage is inferable but not stated.

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