inspect_tailscale

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

Annotations already declare readOnlyHint=true, destructiveHint=false, and openWorldHint=true, so the safety profile is covered. The description adds the useful boundary that it does not configure the VPN, but it does not elaborate on output shape, network behavior, or permissions beyond that.

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 definition is a single efficient sentence. The positive scope is front-loaded and the exclusions follow immediately, with no wasted text.

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 zero-parameter, read-only inspection tool with no output schema, the description supplies enough to understand what is returned conceptually (peer names and addresses) and what it does not do. It could say more about whether results are local-only or network-wide, but the core is adequate.

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?

There are zero parameters, so there is no parameter semantics burden. The description correctly adds no misleading parameter detail, matching the empty schema.

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 uses a specific verb ("Inspect") with a clearly scoped resource ("local Tailscale peer names and addresses"). It is materially clearer than a tautology, though "inspect" remains somewhat broad and no sibling tool covers the same resource for direct contrast.

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?

It gives explicit exclusions: it does not configure VPN or prove Jellyfin identity. This helps an agent avoid misusing it for configuration or identity verification, even though no positive alternative tool is named.

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