Ship-It Backend Doctor Bundle
Five diagnostic doctors, plus Env Doctor free, for when your stack fights back. Debug failing CI and GitHub Actions (CI Doctor), work out why a Docker Compose stack won't come up (Docker Compose Stack Doctor), pinpoint a failed Vercel build or deploy straight from the logs (Vercel Build Log Doctor), audit Supabase row-level security for exposed tables and unsafe policies (Supabase RLS Doctor), and diagnose broken Stripe Checkout, webhooks, and subscriptions (Stripe Webhook & Checkout Doctor). For indie hackers and full-stack developers getting a real app to build, deploy, and run without losing an afternoon to a cryptic error. Each reads the files and logs you give it, ranks the likely cause with evidence, and hands you a fix; none of them touch your live project.
Works with every agent that reads SKILL.md — Claude Code, Cursor, Codex CLI, Gemini CLI, GitHub Copilot, Windsurf, OpenClaw, and more.

5 skills
Diagnose why Stripe Checkout, the Billing Portal, or your webhooks aren't working: missing signature verification, raw-body mistakes, no idempotency, test/live key mix-ups, broken success and cancel URLs, and subscription lifecycle gaps. Works across Next.js, Express, FastAPI, and serverless, with severity, evidence, and copy-paste fixes for each finding.

Audit local Supabase SQL, migrations, policies, storage rules, and client code for RLS gaps, broad policies, service-role leakage, overbroad grants, and tenant-isolation mistakes. Get severity-ranked evidence, proposed fixes, and verification steps without connecting to or changing the live project.

Diagnose why your Docker Compose stack won't come up: port conflicts, bad or missing env vars, absent healthchecks, volume and permission issues, depends_on that doesn't wait for readiness, networking gaps, platform mismatches, and databases that aren't ready. Reads your docker-compose.yml and logs and ranks the blockers with fixes.

Figure out why your Vercel build or deploy failed without scrolling the whole log. Reads the build log plus your package manifest and framework config to pinpoint missing modules, Node and package-manager mismatches, missing env vars, monorepo root mistakes, and serverless/edge runtime errors, with the likely cause and a fix for each.

Debug failing GitHub Actions without scrolling 10,000 log lines. Reads the logs from the first failing step, pinpoints the root cause (missing secret, dependency mismatch, YAML syntax, permissions), and hands you a copy-paste fix, then offers to open the PR. GitHub CLI required.

You say
My Stripe webhooks are failing in production but work locally. Here are my Express route and the error logs from the dashboard.
Your agent does
Found 1 Critical Issue:
- Severity: Critical
- Issue: Webhook signature verification is using the wrong secret.
- Evidence: Express route uses
process.env.STRIPE_WEBHOOK_SECRETwhich contains a local 'whsec_' key. - Fix: Update production env to use the live endpoint secret.
