Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The annotation readOnlyHint=true already conveys the safe read-only nature. The description adds that it lists 'global' nameservers, clarifying scope, and provides the REST endpoint, which is a useful reference but not a behavioral trait. It does not discuss pagination or response format, but these are less critical given the tool's simplicity.
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 two short sentences. The purpose is front-loaded in the first sentence, and the second sentence provides a technical reference without adding fluff. Every word earns its place.
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?
The tool is a simple list operation with no parameters, a read-only annotation, and no output schema. The description sufficiently conveys that it returns the global DNS nameservers; it is complete for this low-complexity tool.
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 tool has zero parameters, and the input schema is empty. The description therefore has no parameters to explain; the baseline for 0-param tools is 4, and the description appropriately omits any parameter details.
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 a specific action ('List') and resource ('global DNS nameservers configured for the tailnet'), distinguishing it from sibling tools like list_dns_searchpaths or list_devices. The verb and object leave no ambiguity.
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 explicit guidance is provided about when to use this tool versus alternatives. The description simply states what it does; it does not mention when one should prefer this over list_dns_searchpaths or other list operations, nor any prerequisites or exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
Add one secure layer between your agents and this server.
Each tool targets a distinct resource and action. For example, list/get/delete keys are clearly separated by operation, and DNS-related tools each address a different aspect (preferences, nameservers, searchpaths, split-dns). No two tools overlap in purpose.
All tools follow the `tailscale_<verb>_<noun>` pattern with consistent vocabulary (list, get, create, delete, set, expire, authorize). The style is uniformly snake_case, making the set predictable.
22 tools is on the higher end but still within a manageable scope for a comprehensive Tailscale API wrapper. Each tool covers a distinct endpoint, and no obvious duplication exists, though the number edges toward heavy.
The server provides strong coverage for devices and auth keys (CRUD plus actions), but DNS preferences, nameservers, search paths, split-DNS, policy file, tailnet settings, and webhooks are read-only. Missing update operations for these tailnet configuration resources are notable gaps for a management tool.
