Get Telnet session status

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

The readOnlyHint annotation already covers safety, and the description adds a useful scoping detail: it checks a visible Windows process rather than a generic session. However, it does not disclose expected return values, behavior for an invalid or unknown sessionId, or whether the check is instantaneous.

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 filler; every word contributes meaning and the key scope qualifier ('visible') is included.

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?

For a simple one-parameter read-only check, the description conveys the high-level behavior, but there is no output schema and no explicit description of the result format. The agent must infer that the tool returns a running/not-running indication and cannot anticipate error behavior.

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?

The description never mentions sessionId or how it relates to the process being checked. Since schema description coverage is 0%, the description was expected to compensate, but the schema's self-explanatory UUID field does most of the work.

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?

Description names a specific verb ('Checks whether ... is still running') and a concrete resource (visible Windows Telnet process), so the tool's core purpose is clear. It doesn't explicitly contrast with the sibling telnet_check, but the status/check wording largely differentiates it.

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?

No when-to-use or when-not-to-use guidance is given. With nine sibling tools, an agent gets no explicit hint about when to call telnet_status instead of telnet_check, telnet_list, or telnet_read; suitability is only implied by the name.

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