get_trace_data

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

No annotations exist, so the description carries the full burden. It describes internal merging behavior but does not disclose whether the tool has side effects (e.g., modifying the cache) or if it is read-only. This lack of transparency lowers the score.

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 moderately concise but contains dense technical details that could be clearer. It is not excessively long, but some sentences are convoluted and could be better structured with bullet points or simpler phrasing.

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 absence of an output schema and annotations, the description should explain return values, error conditions, and parameter meanings. It does none of that, focusing on internal caching behavior, so it is incomplete for an agent to use effectively.

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 has 7 parameters with no descriptions and no coverage in the description. The description mentions frame metadata but never explains parameters like clear, world, frame_url, or function_path. Thus the description adds no semantic value to the inputs.

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?

States a clear action (retrieve) and a specific resource (in-page traces and cross-navigation cache). It also distinguishes itself by describing merge semantics, but does not explicitly name a sibling tool, so a 4 is appropriate rather than a 5.

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?

Does not provide explicit guidance on when to use this tool versus alternatives like list_trace_files or query_trace_file. Some implicit hints about the authoritative cache exist, but no clear selection criteria are given.

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