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 |
|---|---|---|---|
| id | Yes | Subscription id (uuid) returned by subscribe. |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
The description discloses that ownership is enforced and that the row is deactivated rather than deleted, preserving history. This goes beyond the idempotentHint and destructiveHint annotations, adding meaningful behavioral context that an agent needs to know.
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, front-loaded with the primary action, followed by essential behavioral details. No redundant information and every sentence 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?
For a simple single-parameter mutation tool with no output schema, the description covers the action, ownership constraint, and the non-deletion effect. This is sufficient for an agent to understand the tool's behavior and select it 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?
The schema already documents the single 'id' parameter as the subscription uuid returned by subscribe (100% coverage). The description adds 'your own subscriptions' context but doesn't provide additional syntax or format details, so the schema carries the heavy lifting.
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 the specific verb 'Cancel' with the resource 'subscription', clearly differentiating from sibling tools like 'subscribe' and 'list_subscriptions'. It states exactly what the tool does and its scope.
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 states the action and the ownership constraint, implying when to use it (to cancel your own subscription). It doesn't explicitly name alternatives or exclusions, but the sibling context and 'recent_alerts' mention provide clear context for appropriate usage.
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.
Many tools have overlapping research purposes (ask_pipeworx, deep_research, ask_pipeworx_grounded) and multiple bet-related tools (bet_research, polymarket_arbitrage, polymarket_edges). Reactome-specific tools are few but mixed in with unrelated tools, causing ambiguity.
Tool names are inconsistent: some snake_case (ask_pipeworx, deep_research), some camelCase (generate_llms_txt, list_subscriptions), and some mixed (pipeworx_feedback, poly market_arbitrage). No uniform pattern.
35 tools is excessive for a Reactome server, as only a handful are Reactome-specific. Many tools are unrelated (e.g., bet_research, compare_entities), making the tool count feel bloated and unfocused.
The Reactome-specific tools cover basic pathway lookups but miss key operations like reactions, complexes, or advanced queries. The server's completeness for the Reactome domain is poor, diluted by many non-Reactome tools.
