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?
Discloses behavioral traits beyond annotations: ownership enforcement, deactivation (not deletion), and preservation of historical events. No contradiction 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?
Two concise sentences with front-loaded action and no unnecessary words. Every sentence adds essential information.
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?
Adequately covers all needed information: what it does, constraints (ownership), and outcome (deactivation). No output schema needed given clear explanation.
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 has 100% coverage for the single parameter; description adds value by relating ownership enforcement to the id, providing functional context beyond the schema's basic description.
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 the action ('Cancel a subscription by id') with specific verb and resource, and naturally distinguishes itself 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?
States ownership enforcement ('only cancel your own subscriptions') and effect (deactivation not deletion), providing clear context. However, it does not explicitly mention alternatives or when not to use.
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 has a clearly distinct purpose, with detailed descriptions that eliminate ambiguity. Even similar tools like ask_pipeworx, ask_pipeworx_grounded, and deep_research are well-differentiated by use case (casual, high-stakes, multi-faceted). The Polymarket and EOL tool suites are internally distinct.
Naming mostly follows snake_case with verb_noun or prefix patterns, but there is inconsistency: e.g., 'ask_pipeworx' vs 'bet_research' vs 'deep_research'. The Polymarket and memory tool groups are internally consistent, but overall the server mixes conventions across sub-domains.
34 tools is on the high side, but the server covers multiple domains (EOL taxonomy, Pipeworx data, Polymarket betting, memory, subscriptions). The count is borderline excessive for a focused server; meta-tools like discover_tools and suggest_questions help, but the sheer number can overwhelm an agent.
The tool set covers many data sources and analysis tasks well, but the server name 'Eol' implies a biological taxonomy focus, which is underserved (only 4 tools). For the broader implicit purpose of a research assistant, there are notable gaps like open-web search, image analysis, or document management.
