api_monitor_open_capture

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

With no annotations, the description carries the full burden. It hints that 'the real Rohitab API Monitor application' is launched (an external GUI process, a meaningful side effect), but says nothing about permissions, whether it reuses an existing window, what window_handle does, or whether the operation blocks. For a tool that starts an external application, this is a substantial gap.

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?

A single, front-loaded sentence with no wasted words. It is efficient, though its brevity contributes to the missing context rather than being a virtue on its own.

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?

An output schema exists, so return values need not be described. But for a tool that launches an external GUI app, with zero annotations and zero parameter documentation, the description is not complete enough for an agent to invoke it confidently.

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% across all three parameters. The description only loosely implies file_path via 'APMX capture'; the optional install_root and window_handle parameters are entirely unexplained in both schema and description, leaving the agent to guess their purpose and format.

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 states a specific verb and resource ('Open an APMX capture') and implicitly distinguishes itself from sibling api_monitor_save_capture by the open/save contrast. However, it never explicitly names an alternative or scope boundary, so an agent must infer the distinction.

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?

There is no guidance on when to use this versus api_monitor_save_capture, api_monitor_launch, or the many capture_* readers. The user is left to infer that this is for reopening a saved APMX file in the GUI, with no prerequisites or exclusions stated.

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