analyze_network_trace

Parse and extract network request details from a .xctrace file captured with the Network template to diagnose app network performance.

Instructions

Analyze an existing .xctrace file recorded with the Network template.

Behavior2/5

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

No annotations are present, so the description bears full responsibility for behavioral disclosure. It does not mention side effects, permissions, or output format, leaving the agent uninformed about the tool's safety or outcome.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness4/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is a single, clear sentence. It is very concise, but the brevity sacrifices necessary detail for completeness. Still, it is well-structured and front-loaded.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness2/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given the lack of output schema, missing parameter documentation, and no behavioral transparency, the description is insufficient for an agent to understand the tool's full behavior. It does not differentiate adequately from siblings.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters2/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Schema description coverage is 50% (only trace_path is described). The description adds no parameter details; bundle_id is left undocumented in both the schema and description. The agent cannot infer the parameter's purpose from the description.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose4/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description clearly states the tool analyzes an existing .xctrace file recorded with the Network template, which distinguishes it from sibling tools like 'analyze_allocations' or 'analyze_launch'. However, it does not elaborate on what the analysis produces, leaving some ambiguity.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines2/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No guidance on when to use this tool versus its siblings. The description merely states what it does, with no when/when-not instructions or context about prerequisites.

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