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

With no annotations, the description covers the two deployment workflows, including that 'bootproject' writes to the target boot dir and triggers twincat_restart_runtime. However, it omits other behaviors like error handling, auth requirements, or side effects, leaving gaps.

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?

Two concise sentences front-load the primary purpose and method differentiation. Every word is informative with no redundancy, making it efficient for an agent 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?

Despite good coverage of methods, the description fails to address return values, errors, or prerequisites for parameters like 'commandName'. Given the complexity (4 parameters, no output schema), this is incomplete for reliable agent invocation.

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 only 25% (only treePath has a description). The description adds value by explaining the 'method' values, but it does not describe 'autostart', 'commandName', or their interaction, so the agent still lacks full parameter understanding.

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 'Deploy the active PLC project' with a specific verb and resource. It further distinguishes between two methods ('bootproject' and 'command'), providing a clear scope that differentiates from sibling tools like nc or tc_link.

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 explains when to use each method: 'bootproject' for headless deployment via ITcPlcProject, and 'command' for legacy DTE route needing a shell. This gives context for selection, though it does not explicitly state when not to use the tool.

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