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

With no annotations, the description carries full burden. It discloses the autoLogout behavior (logs out via UI Automation if needed and never logs back in) and method differences. However, it does not mention failure scenarios, overwrite behavior, or whether the runtime is restarted after deployment.

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 a single block of text that front-loads the main purpose. It contains useful details without excessive verbosity, but lacks structure (e.g., bullet points for parameters) and could be more scannable for an agent.

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 6 parameters, no output schema, and sibling tools like twincat_restart_runtime, the description should cover deployment nuances. It addresses methods and logout but omits autostart default behavior, commandName usage, treePath selection, and return value expectations. This leaves significant gaps for an agent.

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 coverage is only 17% (only treePath described). The description adds meaning for method, confirm, and autoLogout but ignores autostart, commandName, and treePath details. Even confirm is only implied as required. This is insufficient for a 6-parameter tool with low schema coverage.

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 deploys the active PLC project, using specific verbs like 'deploy' and 'writes to target boot dir'. It distinguishes the two methods (bootproject and command) but does not explicitly differentiate from sibling tools like xae_build or twincat_restart_runtime.

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 provides guidance on when to use each method (headless vs. needing window automation) and the required confirmation token (confirm=

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