Summary

This skill is primarily a prompt-style wrapper with no local secret requirement and no direct executable code in the provided material. However, it is designed to rely on external Rube MCP and Composio/Hackernews connections for tool discovery and execution, so the overall posture is low-to-moderate concern focused on external service interactions rather than the skill itself.

CredentialsCaution

The material says there are no local keys, but actual use requires establishing a Hackernews connection via `RUBE_MANAGE_CONNECTIONS` and completing an external auth flow. This suggests credentials are handled by the external MCP/platform, with normal third-party authorization considerations and limited visibility from the skill itself.

Network egressCaution

The README explicitly requires adding the remote MCP endpoint `https://rube.app/mcp` and using Composio's toolchain for Hackernews operations. This means task content, session IDs, and tool arguments may be sent to the stated external services. This is normal connected-tool behavior, and no unrelated or hidden egress endpoints are disclosed in the material.

Code executionLow risk

Based on the provided material, this is a prompt-only skill that guides calls to existing MCP tools. It does not include local scripts, install commands, or instructions to launch extra processes on the host, so no direct local code execution surface is evident here.

Data accessCaution

The workflow can search tool schemas, check connections, and execute Hackernews-related actions through external tools, potentially handling user-supplied post/comment/account-operation parameters and session data. However, the material does not claim local file access or permissions beyond what is reasonably related to Hackernews automation.

Supply chainLow risk

The source is an open GitHub repository with strong community adoption (~64.9k stars), both of which are meaningful risk-reducing signals. The material itself is auditable and does not show obfuscated setup steps or suspicious injection content. The missing license declaration and unknown maintenance status are worth noting, but not enough on their own to justify a high-risk rating.

Recommendations

Before adding `rube.app/mcp`, verify that your organization permits sending task content and session data to that external service.
When connecting a Hackernews account, prefer a least-privilege account and review the exact scopes granted on the external authorization page.
Inspect the schemas returned by `RUBE_SEARCH_TOOLS` before execution to avoid sending unnecessary sensitive fields.
For production use, further review Composio/Rube privacy policies, log retention practices, and account disconnect procedures.

Hackernews Automation via Rube MCP

Automate Hackernews operations through Composio's Hackernews toolkit via Rube MCP.

Toolkit docs: composio.dev/toolkits/hackernews

Prerequisites

Rube MCP must be connected (RUBE_SEARCH_TOOLS available)
Active Hackernews connection via RUBE_MANAGE_CONNECTIONS with toolkit hackernews
Always call RUBE_SEARCH_TOOLS first to get current tool schemas

Setup

Get Rube MCP: Add https://rube.app/mcp as an MCP server in your client configuration. No API keys needed — just add the endpoint and it works.

Verify Rube MCP is available by confirming RUBE_SEARCH_TOOLS responds
Call RUBE_MANAGE_CONNECTIONS with toolkit hackernews
If connection is not ACTIVE, follow the returned auth link to complete setup
Confirm connection status shows ACTIVE before running any workflows

Tool Discovery

Always discover available tools before executing workflows:

RUBE_SEARCH_TOOLS
queries: [{use_case: "Hackernews operations", known_fields: ""}]
session: {generate_id: true}

This returns available tool slugs, input schemas, recommended execution plans, and known pitfalls.

Core Workflow Pattern

Step 1: Discover Available Tools

RUBE_SEARCH_TOOLS
queries: [{use_case: "your specific Hackernews task"}]
session: {id: "existing_session_id"}

Step 2: Check Connection

RUBE_MANAGE_CONNECTIONS
toolkits: ["hackernews"]
session_id: "your_session_id"

Step 3: Execute Tools

RUBE_MULTI_EXECUTE_TOOL
tools: [{
  tool_slug: "TOOL_SLUG_FROM_SEARCH",
  arguments: {/* schema-compliant args from search results */}
}]
memory: {}
session_id: "your_session_id"

Known Pitfalls

Always search first: Tool schemas change. Never hardcode tool slugs or arguments without calling RUBE_SEARCH_TOOLS
Check connection: Verify RUBE_MANAGE_CONNECTIONS shows ACTIVE status before executing tools
Schema compliance: Use exact field names and types from the search results
Memory parameter: Always include memory in RUBE_MULTI_EXECUTE_TOOL calls, even if empty ({})
Session reuse: Reuse session IDs within a workflow. Generate new ones for new workflows
Pagination: Check responses for pagination tokens and continue fetching until complete

Quick Reference

Operation	Approach
Find tools	`RUBE_SEARCH_TOOLS` with Hackernews-specific use case
Connect	`RUBE_MANAGE_CONNECTIONS` with toolkit `hackernews`
Execute	`RUBE_MULTI_EXECUTE_TOOL` with discovered tool slugs
Bulk ops	`RUBE_REMOTE_WORKBENCH` with `run_composio_tool()`
Full schema	`RUBE_GET_TOOL_SCHEMAS` for tools with `schemaRef`
