Integrate Error Tracking for AI-Ready Prompts

Connect any app to Better Stack using app-specific SDKs like the Sentry React SDK. Generate a DSN from your Better Stack dashboard by selecting your app type—this auto-captures browser info, user steps, session replays, and crafts AI prompts with stack traces. For a React film emulation app (github.com/Orva-Studio/hance), uploading videos and scrubbing the timeline triggered an 'uncaught security error' blocking timeline scrolling. Better Stack surfaced three related occurrences plus 44 unrelated errors, providing root cause analysis like browser details and replay footage without manual setup.

Run npx @betterstackhq/cli mcp or edit Claude Code's config to enable the MCP server. Activate deferred tool loading in Claude settings JSON to load only relevant tools (e.g., error fetchers) into context, saving tokens. Prompt Claude with 'give all error details for this application' to auto-detect your app, summarize latest errors, and suggest fixes—Claude pulls stack traces, related issues, and codebase context in parallel.

Automate Diagnosis to PR Creation

Query specific errors like 'get details for the security error and related issues.' Claude groups them (e.g., excluding 44 unrelated ones), identifies root causes (e.g., one-line code fix in React), and creates feature branches with PRs. In the hance app demo, Claude fixed the timeline security error in seconds: a single code change prevented reproduction after local testing. Merge the PR to deploy—Claude handles branching, commits, and PR descriptions autonomously.

This cuts debugging from browser-copy-paste loops to terminal-only flows, handling high error volumes efficiently. Routine prompts can email/SMS new errors or auto-generate PRs, turning observability into proactive fixes.

Verify Fixes and Close the Loop

Post-merge, prompt 'check if the fix is in place and resolve the issue in Better Stack.' Claude confirms code changes, then uses MCP tools to mark errors resolved across occurrences—no UI visits needed. Demo confirmed: three security errors auto-resolved, visible in Better Stack dashboard. Repeat for all issues to clear backlogs.

Trade-offs: Relies on MCP setup and Claude's tool accuracy (e.g., correct app detection); best for terminal-heavy workflows. Scales to agents replacing UIs for convenience, especially in production apps with sporadic bugs like video scrubbing errors.
