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?
The description goes beyond annotations by disclosing that cancellation deactivates rather than deletes the row and that historical events remain accessible. This adds meaningful behavioral context not present in the annotations or schema.
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 brief sentences, front-loaded with the primary verb and resource. Every sentence contributes a distinct valuable point: the action, the ownership constraint, and the behavioral consequence. No unnecessary words.
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 good annotations, the description is complete. It addresses the action, the ownership rule, and the persistence of historical data, which is sufficient given the tool's low complexity and lack of output schema.
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 input schema already documents the id parameter with a clear description and 100% coverage. The description only reiterates that cancellation is by id, adding no additional semantic value beyond the schema.
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 a specific verb and resource, distinguishing it from sibling tools like subscribe and list_subscriptions. The deactivation detail further clarifies the intended behavior.
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?
It provides clear context by specifying ownership enforcement and the effect on historical events via recent_alerts. It does not explicitly name alternatives or list when-not-to-use cases, but the purpose and constraints are evident from the description and sibling tool set.
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 are very similar (e.g., ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded) and serve the same purpose with slight variations, making it hard for an agent to choose correctly. Additionally, the tool set mixes completely unrelated domains (ArcGIS geospatial vs. Pipeworx/Polymarket data), further confusing the purpose of each tool.
Tool names follow multiple conventions: ask_pipeworx uses snake_case, while layer_info and query_layer use snake_case as well but with a different pattern. There is no consistent verb_noun pattern across the set; some are descriptive (validate_claim) while others are vague (process, run). The mix of conventions and lack of a unified naming scheme hurts predictability.
At 34 tools, the count is excessive for a server supposedly focused on ArcGIS Peoria. Only 3 tools (layer_info, query_layer, search_datasets) are actually related to geospatial data, while the other 31 are from external services (Pipeworx, Polymarket). This mismatch suggests the server is extremely poorly scoped.
For a geospatial server, the tool set is severely incomplete. It lacks basic GIS operations like spatial filtering, editing, or analysis. The three geospatial tools only provide schema discovery and simple attribute queries. Meanwhile, the bulk of the tools cover a completely different domain (data lookup, prediction markets), leaving the core domain almost entirely unaddressed.
