unsubscribeCancel a subscription by id. Ownership is enforced — you can only cancel your own subscriptions. The row is deactivated (not deleted) so its historical events stay available via recent_alerts.

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations show idempotentHint=true and destructiveHint=false; description adds that the row is deactivated (not deleted) and historical events remain available via recent_alerts. This goes beyond annotations and clarifies side effects.
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?
Two concise sentences with no fluff; the purpose is front-loaded. Every sentence adds value.
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?
With one parameter, no output schema, and good annotations, the description provides ownership rules and deactivation behavior, fully covering what an agent needs to use the tool correctly.
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?
Schema covers the single id parameter 100%, with description 'Subscription id (uuid) returned by subscribe.' The description adds no extra meaning beyond the schema, so baseline 3 is appropriate.
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 starts with 'Cancel a subscription by id,' clearly specifying the action and resource. It distinguishes from siblings like 'subscribe' and 'list_subscriptions' by indicating it is the cancellation counterpart.
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?
States 'Ownership is enforced — you can only cancel your own subscriptions,' providing an important constraint. While it doesn't explicitly contrast with other tools, the context implies usage after subscribing.
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.
Several tools are difficult to distinguish: ask_pipeworx and ask_pipeworx_beta are currently identical, and ask_pipeworx_grounded, deep_research, and ask_pipeworx have fuzzy boundaries. The polymarket_* family plus bet_research also overlap heavily, requiring agents to carefully parse long descriptions to avoid misselection.
Naming is predominantly snake_case with a verb-first pattern (ask_, search, subscribe, unsubscribe, list_) and clear prefix families like polymarket_ and pipeworx_. Minor deviations like ai_visibility_check and entity_profile use noun-first phrasing, but the overall pattern is still predictable and readable.
33 tools is heavy for any single server, and the count is especially inappropriate given the server is named Digitalnz but only two tools (search, record) serve that domain. The rest form an unrelated grab-bag of data research, prediction-market, AI-visibility, memory, and utility tools.
The research workflow is fairly well covered: ask/grounded/deep modes, entity resolution, comparisons, claim validation, subscriptions, and alerts all exist. However, the DigitalNZ surface is nearly absent—just search and record—which is a significant gap for the declared server name, while other domains like AI visibility and npm dependencies are isolated one-offs.
