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 critical behavior: row is deactivated (not deleted) and historical events remain available. This adds value beyond annotations, which already indicate destructiveHint=false and 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, front-loaded with core action, every sentence adds value with no redundancy.
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 fully covers purpose, ownership, and side effects, making it 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?
Schema has 100% coverage for parameter 'id' with clear description. The description adds no additional parameter details beyond what the schema provides.
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') and distinguishes from sibling tools like 'subscribe' and 'list_subscriptions' through specific verb and resource.
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 states ownership enforcement ('you can only cancel your own subscriptions'), providing clear context. However, it does not explicitly mention alternatives for canceling others' subscriptions, though none exist in sibling list.
Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.

The vast majority of tools are unrelated to GitLab and cover overlapping domains (multiple ask_pipeworx variants, several Polymarket tools, memory tools). Only three GitLab-specific tools exist, and they are distinct from each other, but overall the set is highly heterogeneous and ambiguous.
Tool names use a mix of conventions: some are snake_case (ask_pipeworx, search_issues), some are compound nouns (get_project, list_subscriptions), and a few are single words (forget, recall). There is no consistent pattern, making it harder to predict tool names.
Despite the server name 'Gitlab Public', only 3 out of 34 tools are related to GitLab. The remaining 31 tools are a collection of unrelated services (Pipeworx data retrieval, Polymarket betting, memory, AI visibility). This is a severe mismatch between the server's stated purpose and its tool composition.
For a GitLab public server, essential tools like project creation, deletion, user management, and merge request handling are completely missing. The Pipeworx tools, while numerous, lack a clear cohesive scope and overlap significantly with each other.
