Argus

An evidence-assembly research agent running on Cloudflare Workflows.

• Demo: argus.coey.dev · fallback live Worker: argus.coy.workers.dev
• Paper: Argus: Evidence Assembly for Scalable Deep Research Agents

argus.coey.dev is the public docs, demo, and dogfood surface for Argus. It remixes the May 2026 arXiv paper into a real utility: ask a question, start a durable workflow, build facets, fetch current arXiv source receipts, let Workers AI assemble evidence cards, dynamically dispatch follow-up searches for thin coverage, and synthesize the compact evidence board.

What runs

Path	Purpose
src/routes/+page.svelte	Public demo UI and evidence-board renderer
src/routes/api/research/	Starts and polls Workflow instances
src/worker.ts	ArgusResearchWorkflow, the durable adaptive loop
src/lib/argus/	Prompts, evidence graph model, live source fetch, synthesis
research/	Paper notes and product reasoning receipts

No placeholder harness directory: the harness is the executable Workflow and its API/UI loop.

Cloudflare primitives

• Workflows — one durable research run; graph gaps create later follow-up steps.
• Workers AI — facet generation, evidence extraction, and final synthesis.
• SvelteKit on Workers — public docs/demo surface and Workflow API.
• Live fetch — arXiv API receipts are real sources, not fixtures.

Run locally

Run the full local multi-Worker system through Wrangler so real local Workflows + remote Workers AI execute against your authenticated Cloudflare account.

bun run dev

Open http://localhost:4173, then click Start Argus workflow. If you only need rapid visual CSS/Svelte iteration without the Workflow API, bun run dev:ui starts plain Vite.

Validate

bun run check
bun run build

check refreshes Wrangler types, clears generated build artifacts that confuse the scaffold's JS checking after a prior build, then runs Svelte type checking. build creates the SvelteKit Worker bundle and dry-runs the separate Workflow Worker deploy.

Deploy

Click the Deploy to Cloudflare button above to clone and deploy a single Worker into your own account. The Worker includes:

• the SvelteKit docs/demo/API surface;
• the ArgusResearchWorkflow binding;
• the Workers AI binding Argus uses for facets, evidence extraction, and synthesis.

The repository build runs vite build, attaches the Workflow export to the generated SvelteKit Worker entrypoint, refreshes Wrangler types, and dry-runs wrangler deploy. That same single-worker configuration is verified locally by bun run preview and deploys with:

bun run build
wrangler deploy

Thesis

Deep research should be a dynamic workflow over a compact evidence graph, not a pile of parallel chat transcripts.
