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?
Beyond the annotations (non-read-only, non-destructive, idempotent), the description adds that ownership is enforced and that the row is deactivated not deleted, preserving historical events. This provides critical behavioral context about side effects and constraints.
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?
The description is two sentences, front-loaded with the main action and followed by two important behavioral caveats. No wasted 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 one-parameter tool, the description covers purpose, ownership, non-destructive behavior, and the relationship to recent_alerts. With the rich annotations and schema, no further context is necessary.
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 single parameter id is fully described in the schema as a UUID returned by subscribe, so the description adds no additional parameter semantics. Schema coverage is 100%, so the 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?
The description clearly states the tool cancels a subscription by id, using the specific verb 'cancel' and identifying the resource. It distinguishes from sibling tools like subscribe and list_subscriptions by focusing on the cancellation action.
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 gives context that ownership is enforced and canceling deactivates rather than deletes, which informs when to use it. It doesn't explicitly name alternatives, but the contrast with recent_alerts suggests the consequence of the action. Clear context but no explicit exclusions.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

The set mixes a general data-querying platform (Pipeworx) with a small Brawl Stars API wrapper. Within the Pipeworx cluster, ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, and validate_claim have overlapping lookup behavior, and the five polymarket_* tools cover similar prediction-market ground. The Brawl Stars tools are distinct but dwarfed, making the overall purpose confusing.
Most Pipeworx tools use snake_case verb_noun patterns (ask_pipeworx, validate_claim, list_subscriptions), but Brawl Stars tools are bare nouns (brawler, club, player) and memory tools are bare verbs (remember, recall, forget). Some names are compound (generate_llms_txt, scan_competitor_ai_presence). No consistent pattern spans the whole set, though each subset is internally coherent.
41 tools is far beyond what a Brawl Stars server needs; only about 10 are Brawl Stars-related. The bulk is a general-purpose data and prediction-market toolkit that seems bolted on. The count is not well-scoped to the server's declared name and purpose.
For Brawl Stars, the surface is thin: player and club profiles exist but there is no player search, club search, brawler-specific per-player stats, or detailed leaderboards. The Pipeworx side has broad coverage but is unrelated to the server name, so the domain is muddled and obvious Brawl Stars endpoints are missing.
