get_langfuse_trace_detail

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

With no annotations, the description carries full burden. It describes the return payload but does not disclose behavioral traits like idempotency, rate limits, or error conditions. Adding notes on safety (read-only) and required auth would improve transparency.

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?

Two sentences purpose-first, no filler. Efficiently communicates purpose and return content. Every sentence earns its place.

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, an output schema, and 100% parameter coverage, the description is nearly complete. It lacks only minor usage context (e.g., idempotency note), but overall covers the essentials.

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 coverage is 100%, so the description adds no parameter meaning beyond the schema. The baseline of 3 applies; the description mentions 'by its ID' but trace_id is already well-documented in 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 verb 'Fetch', resource 'full detail for a single Langfuse trace', and the method 'by its ID'. It lists returned components (input/output, observations, scores, metadata), distinguishing it from siblings that list traces or filters.

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 use when needing full detail of one trace, and the contrast with siblings (fetch_langfuse_traces, list_langfuse_trace_filters) is clear. However, it does not explicitly state when not to use or mention alternatives, which would earn a 5.

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