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

With no annotations provided, the description carries the full burden of behavioral disclosure. It effectively describes key behaviors: it retrieves data (read operation), can clear data after retrieval (destructive if clear=True), and includes persistent data across navigations. It also specifies the return format (dict mapping function paths to call records). This covers most critical aspects, though it lacks details on rate limits or error handling.

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 well-structured and front-loaded: the first sentence states the purpose, followed by a clear 'Args' section with bullet points for each parameter and a 'Returns' section. Every sentence adds value without redundancy, making it efficient and easy to parse.

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 no annotations, 0% schema coverage, and no output schema, the description does an excellent job of covering purpose, parameters, and return values. It explains the tool's behavior and output format thoroughly. A minor gap is the lack of error cases or performance considerations, but it is largely complete for the tool's complexity.

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 description coverage is 0%, so the description must compensate fully. It provides detailed semantics for all three parameters: function_path (filters traces, optional), clear (clears data after retrieval), and include_persistent (includes cross-navigation data, default True). This adds significant meaning beyond the bare schema, explaining usage and defaults clearly.

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 tool's purpose: 'Retrieve trace data collected by trace_function.' It specifies the verb ('Retrieve'), resource ('trace data'), and source ('collected by trace_function'), distinguishing it from siblings like get_breakpoint_data or get_console_logs. The mention of trace_function as the data source provides specific context.

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 usage by referencing trace_function as the data source, suggesting it should be used after trace_function has collected data. However, it does not explicitly state when to use this tool versus alternatives like get_breakpoint_data or get_property_access_log, nor does it provide exclusions or prerequisites. The guidance is implied rather than explicit.

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