Production AI Workflows & Multi-Agent Blueprints

Gemini Spark dropped from the $99.99 Ultra tier to the $19.99 AI Pro plan on July 25, 2026, making always-on personal agents a consumer product. This workflow builds spark-sleeper, a LangGraph pipeline that runs a personal agent 24/7 on cloud compute: it ingests tasks from any device, wakes on schedule or trigger, executes long-running work with a durable task queue, checks every spend against a hard monthly cap, and reports results back to the user's channel of choice — the Gemini Spark pattern as an open workflow you control.

Assort Health raised a $120M Series C at a $1.2B valuation in August 2026, expanding from voice AI into an agentic system for the whole patient journey. This workflow builds care-flow, a LangGraph pipeline for healthcare front offices: a voice agent answers inbound calls, triages the request with structured symptom intake, books or reschedules appointments against the practice schedule, and routes anything clinically uncertain through a human escalation gate before any medical decision.

Google's agentic shopping features now place real calls to stores, and consumer callers like Assindo navigate IVR menus and hold queues. This workflow builds call-runner, a LangGraph pipeline that makes outbound calls for a user: it plans the call from a task brief, dials through Twilio, navigates IVR menus with speech recognition, handles hold queues, executes the script, and logs a completion verdict — done, needs callback, or failed — with a transcript the user can check.

Hazmat (open-source, ~Aug 17 2026) runs AI coding agents in a dedicated least-privilege OS account so they cannot read SSH keys or cloud credentials, backed by a TLA+ formal spec, per-session macOS backups, and a session-scoped firewall. This dispatch builds agentcell, a LangGraph workflow that plans a session with declared paths, generates a per-session sandbox policy, preflights a backup, spawns any harness (Claude Code, Codex, OpenCode, Cursor) inside the account, and terminates on the first escape attempt.

OpenAI shipped cross-model delegation in Codex Multi Agents v2 (Aug 15, 2026): GPT-5.6 Sol orchestrates while delegating narrow tasks to cheaper GPT-5.6 Luna pure subagents that cannot spawn more agents, with guidance (Provencher) capping fan-out at 6-8 subagents. This dispatch builds modelrouter, a LangGraph workflow implementing capability-tier routing: an orchestrator decomposes a job, routes each task to the cheapest capable tier, enforces a max subagent count, and uses a quality gate to re-escalate failed tasks to a higher tier.

Cloudflare Agents Week (Aug 4-15, 2026) launched Cloudflare Wallets and cloudflare.pay on the x402 protocol so agents can hold verifiable identity and purchase within human-set limits, plus an Identity-Aware AI Gateway (Aug 5, 2026) attaching verified identity to every outbound AI request. This dispatch builds machpay, a LangGraph payment workflow where an agent requests a purchase, the workflow validates the request against a human-set spend ceiling, checks wallet balance, settles via x402 in a single idempotent request, and logs every spend line to an audit ledger with identity attribution.

Zeplyn's Schwab integration (Aug 12, 2026) showed agentic account opening cuts NIGO by 80% — but regulated account opening needs compliance rails, not just automation. This workflow builds account-open, a LangGraph pipeline that drafts the entire account-opening workflow, runs KYC/AML and eligibility checks, routes every uncertain field to a human approval gate, and writes an immutable audit trail before submission. It is the assisted-automation pattern for regulated finance.

DISCO's Advanced Research GA (Aug 13, 2026) proved agentic eDiscovery can investigate facts autonomously — but legal defensibility demands citations on every finding. This workflow builds fact-finder, a LangGraph pipeline where an investigator agent plans a line of inquiry, runs multi-step searches across a document corpus, assembles findings with per-claim citation trails, and routes the trail through a human review gate before anything is admitted as a conclusion.

Chainlink for Agents (Aug 14, 2026) made CCIP cross-chain settlement a first-class agent capability — which means every agent transfer is now a governance decision. This workflow builds settle-bot, a LangGraph pipeline that sits between an agent and its money: it verifies the transfer against verified price feeds, checks per-transaction caps and policy, routes value movement through a human approval gate, and writes an immutable audit record before and after settlement.

Code for India's Code for a Billion — Bharat Agentic-AI Hackathon 2026 (Aug 15, 2026) targets education, health, climate, governance, and financial inclusion. This dispatch builds civic-serve, a LangGraph workflow that turns public-service intents into governed agent actions: intake plus eligibility check, privacy-gated data access, multilingual output, human approval for entitlement-changing actions, and an append-only audit for public-sector transparency compliance.

The 2026 agent-browser wave (Cloudflare Kitesurf) and QF-Test 11.0.1's MCP server let Claude Code and GitHub Copilot plug into automated testing. This dispatch builds web-native-tester, a LangGraph workflow that drives a lightweight headless browser runtime, orchestrates web-platform tests via an MCP server, collects results, and routes failures into a human-fix loop with retry and regression tracking.

Alteryx Agent Studio (Inspire 2026) lets business analysts convert trusted data workflows into autonomous agents without IT. This dispatch builds analyst-deploy, a LangGraph workflow with a three-stage pipeline: an analyst defines rules in a structured spec, an agent builder compiles the spec into a deployable agent with tool mappings, and a governance gate enforces approvals, a scope allowlist, and audit before pushing to Slack, Teams, or an external model channel. Rollback and versioning are first-class.
