enable_telnet

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

With no annotations provided, the description carries the full burden of behavioral disclosure. It only states the basic action (enable/disable) without revealing side effects, whether active Telnet sessions are terminated, persistence across reboots, or required permissions. For a state-changing tool, this lack of transparency is a significant gap.

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, concise phrase 'Enable/Disable Telnet Service' with no filler or redundant words. It is front-loaded with the key action and resource, making it immediately clear. Every word serves a purpose.

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 the low complexity (one boolean parameter) and the presence of an output schema, the description covers the core function and the schema clarifies the parameter. However, with no annotations and no mention of operational context (such as service availability or security implications), the description is only minimally sufficient. It's enough to understand what the tool does but omits surrounding details that could affect 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?

The input schema already documents the 'enabled' boolean with descriptions for True (Enable) and False (Disable), giving 100% schema coverage. The tool description merely restates this mapping without adding new meaning. It doesn't explain edge cases like idempotency or the effect of setting the same value twice, so it meets the baseline but adds no extra value.

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 'Enable/Disable Telnet Service' clearly uses a specific verb and resource, directly stating the tool's action. It distinguishes itself from siblings like enable_ssh and enable_ftp by explicitly naming Telnet, leaving no ambiguity about which service it controls.

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 implies usage through its action statement—use this tool when you need to turn Telnet on or off. However, it provides no explicit comparison to alternatives, no mention of prerequisites, and no guidance on when not to use it. The usage is self-evident from the name and description, but no extra context is given.

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