list_subscriptionsList the caller's active subscriptions. Returns id, type, params, created_at, last_fired_at, fire_count for each. Use this to review what you're monitoring before adding more or to find an id to cancel.
| Name | Required | Description | Default |
|---|---|---|---|
| include_inactive | No | Include cancelled subscriptions in the response (default false). |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already declare readOnly, idempotent, and non-destructive, so the bar is lower. The description adds behavioral details beyond the annotations: it lists the exact returned fields (id, type, params, created_at, last_fired_at, fire_count) and clarifies the scope as the caller's own subscriptions. It also implicitly discloses that only active subscriptions are returned by default, matching the include_inactive parameter semantics.
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 three sentences, front-loaded with the core action, followed by a concise list of return fields and a clear usage directive. 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 list tool with a single optional parameter and no output schema, the description covers the purpose, return format, and usage scenario. Combined with the schema and annotations, an agent has all needed to select and invoke the tool correctly.
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 schema fully documents the only parameter (include_inactive) with a default value, so schema_description_coverage is 100%. The description itself does not mention this parameter, so it adds no additional meaning beyond the schema; 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?
The description uses a specific verb 'List' with a resource 'the caller's active subscriptions' and enumerates the return fields. It distinguishes from sibling tools by explicitly framing this as a review step before adding more subscriptions or finding an id to cancel.
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 explicitly states when to use the tool: 'Use this to review what you're monitoring before adding more or to find an id to cancel.' This gives clear context and implies alternatives (subscribe/unsubscribe) without needing to name them.
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.
