analyze_gimbal_pid

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

With no annotations provided, the description carries the full burden. It discloses the threshold and preferred workflow, but does not explicitly state that the tool is read-only or describe side effects. It adds some behavioral context (threshold, input modes) but lacks a complete safety/impact profile.

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 two sentences, front-loaded with the purpose and followed by input-mode guidance. Every sentence adds value, and the structure is efficient and appropriately sized.

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?

The tool has six parameters and an output schema, and the description gives core domain context (gimbal PID, 0.006 rad threshold) and input preferences. However, it omits details about how the analysis is performed, what the threshold is used for, and how other parameters affect the analysis, leaving some gaps for a domain-specific tool.

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. It adds meaning to topic_data and bag_path ('passing in-memory topic_data directly from capture_topic_sync' and 'Accepts bag_path for offline analysis'), but provides no semantics for axis, loop, signal_type, or skip_initial_sec, which are only represented by enums/defaults.

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 identifies the tool as an analysis tool for RoboMaster Gimbal PID tracking error with a specific threshold ('0.006 rad threshold'). This distinguishes it from siblings like analyze_step_response by focusing on PID tracking error, though it does not explicitly name alternatives.

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 second sentence provides clear context for input selection: 'PREFER passing in-memory topic_data directly from capture_topic_sync for fast tuning loops without disk I/O' and 'Accepts bag_path for offline analysis.' This outlines when to use each input mode, but does not compare against sibling analysis tools.

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