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 |

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?
Annotations already signal non-read-only and idempotent behavior, but the description adds critical context: the row is deactivated, not deleted, and historical events stay accessible. This clearly explains the side effects beyond what structured annotations convey.
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 dense sentences front-load the primary action and then provide essential constraints and side-effect details. Every sentence earns its place with no filler or 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 single-parameter tool with rich annotations, the description sufficiently covers purpose, ownership, deactivation semantics, and historical availability. No output schema exists, so explaining return values is unnecessary.
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 already fully documents the 'id' parameter as a subscription uuid returned by subscribe. The description merely says 'by id' and adds no extra meaning beyond the schema, warranting the baseline score for high schema coverage.
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 opens with 'Cancel a subscription by id', a specific verb+resource pairing that clearly communicates the action. It also distinguishes itself from siblings like subscribe and list_subscriptions by emphasizing the deactivation behavior and preservation of history.
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 implies when to use the tool by noting ownership enforcement and that historical events remain available via recent_alerts. However, it does not explicitly enumerate alternative tools or state when not to use it, so it falls short of full guidance.
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.
There is significant overlap among many tools: ask_pipeworx, ask_pipeworx_beta, ask_pipeworx_grounded, deep_research, and validate_claim all serve query-answer purposes with subtle differences, and multiple polymarket tools (polymarket_arbitrage, polymarket_edges, polymarket_edge_tracker, polymarket_fill_risk, polymarket_kalshi_spread) cover similar arbitrage/mispricing territory. Additionally, ai_visibility_check and scan_competitor_ai_presence clearly overlap, making it hard to pick the right one.
Tool names follow no consistent pattern. Some use a gh_ prefix (gh_get_file, gh_get_repo, etc.), others are descriptive phrases (ask_pipeworx, compare_entities, bet_research), and a few are plain verbs (remember, recall, forget, subscribe, unsubscribe). The mixed conventions and varied verb/noun styles make the set feel disjointed.
At 37 tools, the count is high but still within a usable range. However, the server is named 'Github_private' yet includes only 7 GitHub-specific tools and 30+ unrelated tools (Pipeworx data, Polymarket betting, memory, etc.). This suggests the server aggregates multiple unrelated domains, making the count feel bloated for its apparent GitHub purpose.
Given the server name, the GitHub tool surface is severely incomplete: there are no create/update/delete operations for repos, no PR creation or merging, no issue comments, no branches, and no search across repos. The Pipeworx side is fairly comprehensive, but the mismatch between the server name and the actual tool set leaves major gaps for expected GitHub workflows.
