get_langsmith_traces

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

With no annotations, the description carries the full burden of behavioral disclosure. It does not specify whether the operation is read-only, whether it has side effects, rate limits, or performance implications. The description mentions 'fetch' but omits details about output structure or authentication requirements beyond what is in the schema.

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, clear sentence that front-loads the verb and resource. It contains no redundant information and is appropriately concise.

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?

The tool has no output schema, so the description should explain what the returned traces look like or how they are structured. It does not. Additionally, it lacks context on the optional parameters' practical effects or when to customize defaults, making it insufficient for a tool with 3 optional parameters and no required ones.

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 schema already provides descriptions for all three parameters (days, limit, api_key), covering 100% of the parameter semantics. The tool description adds no further meaning or context about these parameters, so the baseline of 3 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 clearly states the action (Fetch) and the resource (LLM traces from LangSmith), along with the purpose (runtime analysis). It distinguishes itself from sibling tools like get_helicone_events and get_inferencemax_benchmark by specifying the exact data source and type.

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 given on when to use this tool versus alternatives, or any exclusions or prerequisites. The description only states what the tool does, leaving the agent to infer usage from the sibling list and tool name.

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