AI Deploy Gatekeeper Built with Coral and Gemini
A developer (Jinish Gupta) built Harbourmaster, a CLI deploy gatekeeper that queries six operational sources (GitHub, Sentry, Datadog, PagerDuty, StatusGator, Linear) via Coral SQL and uses Google’s Gemini 2.5 Flash to produce a GO/CAUTION/HOLD verdict. The tool aggregates live signals into a structured "Readiness Snapshot," feeds that JSON to Gemini with a strict system prompt, and returns a riskScore, confidence, reasoning, and on-call contacts. Implementation uses TypeScript/Node.js (Commander.js), invokes Coral via WSL, and renders terminal UX with chalk and boxen. The article was published on dev.to and the author published the project source on GitHub. Publication date: 2026-05-31.
Practical demonstration of combining an LLM (Gemini) with live operational signals (via Coral) to automate deploy gating—useful as a reference for engineering teams but not industry-shifting.

Key Takeaways & Evidence Grounding
- Developer built Harbourmaster, a CLI tool that queries six sources (GitHub, Sentry, Datadog, PagerDuty, StatusGator, Linear) to assess deploy readiness.
- Coral (open-source SQL engine) was used to query external APIs as SQL tables, avoiding bespoke REST integrations.
- Google’s Gemini 2.5 Flash was used to reason over the aggregated JSON "Readiness Snapshot" and emit a verdict (GO, CAUTION, HOLD) plus a riskScore and confidence.
- The CLI is implemented in TypeScript/Node.js (Commander.js), invokes Coral via WSL on Windows, and formats output with chalk and boxen.
- Article and project source were published on dev.to and a GitHub repository (publication date 2026-05-31).

Virtual SOC Analyst Built with Gemma 4
A developer published an AI-powered Virtual SOC (Security Operations Center) Analyst (analista.byronlainez.click) that ingests large cloud security logs (AWS CloudTrail, WAF, Nginx), maps findings to MITRE ATT&CK and OWASP Top 10, generates deployment-ready AWS WAF block rules and Terraform HCL, and performs multimodal visual triage on screenshots. The system uses Google’s Gemma 4 model family (examples: 27B, 31B, 4B), offering both cloud-mode forensic correlation (large-context models with a 128K token window) and a privacy-first local mode that runs Gemma 4 4B in the browser via a WebLLM/Web Worker so logs need not leave the machine. The author published a demo app, a GitHub repository, and an end-to-end example log (timestamped 2026-05-21) showing automated detection and an immediately deployable WAF rule JSON.
Cairn: Portfolio Verifier Uses Gemma 4 Vision
A developer built Cairn, a personalized AI learning and career engine that generates adaptive 12-week study and project plans and verifies shipped projects with a three-stage evaluation pipeline. Cairn's pipeline runs deterministic structural checks, a Gemma 4 27B code review, and a Gemma 4 12B vision-powered visual review that inspects up to four screenshots of a running app. Passing projects receive an HMAC-signed credential posted to a public portfolio URL. The implementation includes a provider-agnostic LLM router with runtime fallbacks (Google AI Studio, OpenRouter, others), a TypeScript full-stack monorepo (Next.js 15 frontend, Express backend, MongoDB Atlas), Cloudflare R2 for screenshots, and payment integrations (Razorpay, Stripe). The post is a Gemma 4 Challenge submission and includes demo links and source code on GitHub.
RepoSense: CLI GitHub Intelligence Built with Coral SQL
RepoSense is an open-source command-line tool that provides fast repository intelligence by querying live external APIs as SQL tables via Coral. It surfaces triage signals (oldest unattended issues, stale PRs, release notes, CVE scans, contributor activity, duplicates, repo health, cross-source ‘pulse’ linking Hacker News to GitHub, Stack Overflow and Dev.to buzz) and includes an interactive agent mode where an LLM (Claude, Groq, or GPT-4o) writes and executes Coral SQL via a coral_query tool. The project runs entirely in the terminal with no data warehouse or ETL; queries hit live APIs (GitHub, Hacker News, OSV, Stack Overflow, Dev.to, OpenSSF Scorecard). RepoSense is open-source (MIT) and the article was published on 2026-05-31.
