C2.9/5.0
Behavior3/5

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

Annotations already declare readOnlyHint, idempotentHint, openWorldHint and destructiveHint=false, so the safety profile is covered. The description usefully adds the environment requirement (trusted owner, interactive Windows x64 desktop), which is real context not in the annotations, but it omits blocking behavior and what happens when the timeout elapses.

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?

Two short sentences, front-loaded with the operation and then the prerequisite, with no filler. Only minor fault is the compressed phrasing that assumes the reader knows the AutoIt function semantics.

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

Completeness3/5

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

With no output schema and only two fully documented parameters, the structured fields do most of the work, and annotations cover the safety profile. Still missing is the blocking/timeout outcome an agent needs to handle the call correctly, which matters for a wait-style tool capped at 25 seconds.

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

Parameters3/5

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

Schema coverage is 100% and both parameters carry their own descriptions including the 1-25 second bound and default of 10. The description adds nothing about parameter meaning or interaction between process name/path and timeout, so the baseline 3 applies.

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

Purpose3/5

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

The description names the library operation ('Windows AutoIt processWait') and the platform, so an agent can infer it waits for a process. However, 'processWait' is essentially a restatement of the tool name, and it never clarifies that it blocks until the named process starts, which is the key distinguishing behavior versus siblings like processExists and processWaitClose.

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?

It states an environment prerequisite (trusted owner, interactive Windows x64 desktop) but gives no guidance on when to choose this over processExists, processWaitClose, or runWait, all of which sit in the same sibling cluster. No when-not-to-use or alternative routing is provided.

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