ChronoSyntax: Building an Anomaly Incident Control App with Sanity App SDK & Autonomous AI Workflows
This is a submission for the MLH x DEV Writing Challenge
What I Built
Most headless CMS projects treat content as inert, static text: a blog post with a hero image, published once and forgotten. I wanted to build something fundamentally different—an interactive, real-time application that turns structured content into an active operational nervous system.
I built ChronoSyntax: The Multiversal Anomaly Broadcast Network.
ChronoSyntax reimagines the Sanity Content Lake as a live incident control and telemetry mesh monitoring dimensional anomalies and occult radio signals across spacetime.
Key Capabilities:
- Workflows Modeled as Data (workflow.state): Instead of an ordinary status string (status: 'draft' | 'published'), the entire editorial lifecycle is modeled as first-class structured content directly next to the document. Documents advance through a 6-stage pipeline (Raw Intercept → AI Agent Enrichment → Polyglot Reality QC → Lead Chronicler Human Review → Director Sealed → Live Broadcast).
- Autonomous Agent & External Webhooks: An AI agent (Agent-Gemini-Theta) autonomously queries incoming intercepts, calculates hazard classes (Safe, Euclid, Keter, Reality-Bending), decrypts occult radio ciphers, and triggers an automated external HTTP webhook to an incident relay before handing off the draft to human archivists.
- Custom Studio Input (Video-to-GIF Glitch Synthesizer): Replaces generic file uploaders with an interactive canvas frame buffer. It samples procedural feeds (Wormhole flux, CRT static, Abyssal bioluminescence) or user videos, applies real-time shaders (Phosphor CRT, RGB chromatic aberration, 1-bit retro dither), extracts frame sequences, and commits lightweight looping GIF assets directly into the Sanity document.
- The App SDK (Interactive Incident Control Deck): Rather than another read-only blog, this custom operational application executes real-time bidirectional mutations against the Content Lake (client.patch, client.create, client.listen), casts reality anchors, and plays binaural carrier drones via the Web Audio API.
- Real-time GROQ Query Studio: A live in-app GROQ playground with sub-millisecond execution telemetry, projection testing, and instant JSON inspection.

Partner Technologies
- Sanity (Content Lake, GROQ, App SDK & Workflows) Sanity was the foundational data layer for the entire project. Rather than using it purely as a back-office blog CMS, I pushed into its advanced capabilities: Sanity App SDK & Real-Time Subscriptions: Built an interactive frontend that subscribes to the Content Lake via client.listen() and executes atomic patch operations (client.patch(id).inc({ containmentIntegrity: 4 }).commit()) with immediate optimistic UI updates. Workflows as Data (@sanity/workflow pattern): Modeled workflow state as a first-class schema object with append-only polymorphic audit history arrays ({ type: 'agent' | 'human' | 'system', name: string, note: string }). Both automated AI agents and human chroniclers execute transitions through the same state machine. Custom Input Component: Implemented a custom field input that mounts an interactive HTML5 Canvas inside the Studio to capture, filter, and compile video frames into animated GIF assets. GROQ (Graph Relational Object Queries): Structured queries using projections, aliases, sort orderings, and aggregate count expressions (*[_type == "anomaly" && dangerLevel > 60] | order(dangerLevel desc)).
- Google Gemini AI (@google/genai) Implemented server-side autonomous agent intelligence using the gemini-3.8-flash model: Decrypts raw radio carrier waveforms and extracts structured occult telemetry. Evaluates anomaly hazard parameters and outputs clean JSON matching the containment protocol schema. Built an automatic graceful fallback to an internal neural engine to guarantee zero downtime and 100% testability.
- Web Audio API Used the native Web Audio API to create binaural drone synthesizers mapping anomalous document frequencies (MHz) into audible carrier hums and detuned beat frequencies.
Hackathon Experience
Building ChronoSyntax during the hackathon was an intense masterclass in rapid prototyping, vibe-coding, and pushing developer tooling to its limits:
The Vibe-Coding Pivot: When I first started prompting the application, AI assistants kept nudging the project toward a standard, passive blog template. The pivotal breakthrough came when I forced the model to think in terms of operational state: "We are not building a reader; we are building an interactive control deck where every button press patches the database and every document transition has an audit trail."
What Surprised Me: How powerful modeling workflows as structured content really is. In past hackathons, tracking editorial status meant hardcoding enums or maintaining ephemeral webhook queues. Storing workflow.state directly on the document makes agent handoffs, human sign-offs, and webhook audit trails completely resilient to failures.
What I Learned: Balancing optimistic client-side UI mutations with real-time streaming listeners requires strict revision tracking (_rev). Using Sanity's transactional mutations prevented race conditions when both operatives and automated agents touched the same document.
