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?
Discloses key behaviors beyond annotations: ownership enforcement, row deactivation rather than deletion, and preservation of historical events via recent_alerts. Consistent with annotations (destructiveHint false, idempotentHint true).
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 sentences efficiently convey action, constraints, and side effects. No extraneous information; every word serves a purpose.
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?
Given the tool's simplicity (single parameter, no output schema), the description covers all necessary aspects: what it does, ownership, behavioral effect, and relation to sibling tool. Complete for agent usage.
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 already provides full coverage (100%) and parameter description. Description adds no additional semantic value beyond restating 'by id'. 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?
Description clearly states 'Cancel a subscription by id' with a specific verb and resource. It distinguishes from sibling tools like subscribe (opposite) and recent_alerts (historical events preserved).
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?
Explicitly enforces ownership ('you can only cancel your own subscriptions'), providing clear context for when to use. The mention of deactivation (not deletion) guides against using it for full removal, though explicit alternatives are not named.
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.
Most tools have clearly distinct purposes, but there is some overlap among data query tools like ask_pipeworx, ask_pipeworx_grounded, deep_research, entity_profile, compare_entities, and recent_changes. However, detailed descriptions and different use cases help an agent distinguish them, so it is mostly clear.
All tool names follow a consistent lower_snake_case pattern with a verb_noun style (e.g., ask_pipeworx, list_subscriptions, validate_claim). There are no mixed conventions, making it predictable and easy to understand.
With 31 tools, the server covers a broad domain of data queries, prediction markets, memory, and subscriptions. While slightly more than typical, each tool earns its place and the count is reasonable for the comprehensive platform scope.
The tool surface is extensive, covering data querying, analysis, entity resolution, comparison, change tracking, memory, subscriptions, and more. There are no obvious gaps; it supports a wide range of user intents for the server's purpose.
