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.
| Name | Required | Description | Default |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Beyond the annotations (which include idempotentHint=true, destructiveHint=false, etc.), the description adds key behavioral details: ownership enforcement, deactivation instead of deletion, and preservation of historical events. No contradictions with annotations.
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?
Three sentences: first states the action, second explains ownership constraint, third clarifies behavioral effect. No wasted words, key points front-loaded.
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 description adequately covers behavior and constraints for a simple idempotent tool with one parameter. While it lacks explicit mention of return value or confirmation, the behavioral effects are well described. Missing output schema means the description must stand alone, which it does reasonably well.
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 id parameter is fully documented in the schema with a description referencing the subscribe tool. The tool description adds no new parameter information beyond what the schema provides. With 100% coverage, 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 clearly states it cancels a subscription by id, using a specific verb 'Cancel' and specific resource 'subscription'. This clearly distinguishes it from sibling tools like subscribe and list_subscriptions.
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 mentions ownership enforcement and the effect of deactivation, giving clear context on when it's appropriate. However, it does not explicitly state when not to use it or name alternative tools for edge cases.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

Many tools have overlapping purposes, especially the Pipeworx query tools (ask_pipeworx, ask_pipeworx_grounded, deep_research, validate_claim) which all provide factual answers, making it unclear which to use. The set also mixes Zendesk tools with a large number of prediction market and data tools, creating confusion.
Naming conventions are inconsistent: Zendesk tools use 'zd_' prefix, Pipeworx tools use various prefixes like 'ask_', 'bet_', 'compare_', etc., and some are named with full words. There is no uniform pattern across the set.
35 tools is high for a server named 'Zendesk', especially since only 5 are Zendesk-specific. The majority are unrelated to Zendesk, indicating the tool count is inappropriate for the implied purpose.
For a Zendesk server, the tool set is severely incomplete, offering only basic CRUD operations (get, list, search for tickets and users). Missing essential Zendesk features like ticket creation, update, delete, or macros, while containing many irrelevant tools from other domains.
