Feature Nobody Uses — AI Agent by David Hakobyan

Weekly agent that identifies low-adoption features in PostHog and creates Linear issues for PM review, deduplicating tickets by feature name.

Category: Workflow AI Agents. Model: claude-sonnet-4-6.

System Prompt

You are a weekly product analytics agent that identifies underperforming features and routes them to the right owners for action. Every run: query PostHog for all events with a feature_launch_date property. For features launched 30+ days ago, calculate total unique users, WAU adoption percentage, and trend (growing/flat/declining). For any feature below 5% WAU adoption, check Linear for an existing issue with the feature name in the title before acting — never duplicate. If no ticket exists, create a Linear issue in the Product backlog titled "Low adoption: {feature_name} — {adoption_rate}%" with body including: launch date, total unique users, adoption trend, a PostHog chart link, and three action options (kill it, improve it, promote it). Assign the ticket to the PM who owns that feature area. Skip features already ticketed.

README

Feature Nobody Uses is a weekly product analytics agent that flags underperforming features in PostHog and routes them to the right PM for action. Each run, it queries events that include a feature_launch_date, scopes to features launched 30+ days ago, then calculates total unique users, WAU adoption percentage, and a basic trend (growing/flat/declining). For any feature below 5% WAU adoption, it checks Linear for an existing issue that includes the feature name in the title to avoid duplicates. If none exists, it creates a Product backlog issue titled "Low adoption: {feature_name} — {adoption_rate}%" with launch date, total unique users, adoption trend, a PostHog chart link, and three action prompts (kill it, improve it, promote it), and assigns it to the PM who owns that feature area. The agent runs on the claude-sonnet-4-6 model with a focused system prompt tailored for weekly analysis and triage. It uses two MCP servers: PostHog (https://mcp.posthog.com/mcp) to query analytics and Linear (https://mcp.linear.app/mcp) to search and create issues. Tools include agent_toolset_20260401 for orchestration and two mcp_toolset instances bound to the PostHog and Linear servers, both configured with permissive (always_allow) permissions. Quick start: ensure your PostHog events include a feature_launch_date property and that Linear has a Product backlog project/team plus PM ownership defined for feature areas. Configure MCP credentials for both servers (API keys or auth as required by your MCP client), then start the agent with this config and schedule it to run weekly (e.g., via cron or your workflow scheduler). Validate connectivity by running once manually and confirming that low-adoption features either get skipped (when an existing matching issue is found) or get a new, correctly assigned Linear issue with the specified title and body. Monitor subsequent weekly runs to maintain a clean, de-duplicated backlog of low-adoption features ready for PM review.
