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 that operation is not destructive (deactivates, not deletes) and enforces ownership, adding beyond annotations. No contradictions with annotations (idempotentHint=true, destructiveHint=false).
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 action. Every sentence adds necessary context.
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 tool with one parameter and no output schema, the description covers ownership, behavioral effects, and parameter source, making it fully complete.
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?
Single parameter 'id' is fully described in schema. Description does not add meaning beyond the schema, so baseline 3 applies.
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?
Clearly states 'Cancel a subscription by id' with a specific verb and resource. Distinguishes from its sibling 'subscribe'.
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?
Explains ownership enforcement and that rows are deactivated not deleted, providing context for when to use. Could explicitly mention alternatives but context is sufficient.
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.
Multiple tools have overlapping purposes, particularly the various data query tools (ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, bet_research, etc.) that share similar functionality with subtle differences. The detailed descriptions help but the boundaries are not always clear, making it hard for an agent to reliably select the correct tool.
The naming follows a mix of patterns: some tools use consistent verb_noun (subscribe, unsubscribe, remember, recall) but others are inconsistent (ask_pipeworx vs deep_research vs entity_profile). The main data tools have a common prefix but diverge in style, and the presence of tools like passive_aggression_detect and generate_llms_txt adds further inconsistency.
With 32 tools, the server feels bloated. Many tools could be consolidated (e.g., the ask_pipeworx variants, the Polymarket tools). The inclusion of tangential tools like passive_aggression_detect and generate_llms_txt suggests scope creep. A typical well-scoped server would have 10-15 tools.
The server covers a wide range of data access and some auxiliary functions (memory, subscriptions, feedback), but there are notable gaps like user authentication and data visualization. The addition of an unrelated sentiment analysis tool makes the surface feel incomplete for a focused data server.
