Harmonia — the autonomous social media agent for startups Harmonia turns one authorized source into a governed content operation. Its specialist agents find the signal, shape the strategy, produce platform-native work, pause for human authority, and verify every approved external effect. Source to signal to proof. Creative judgment stays agentic. Workflow truth, permissions, cost controls, publishing, receipts, and verification stay deterministic.

See what Harmonia does

Understand the product promise, operator experience, and governed content loop.

Run the stack

Start the web app, ADK worker, Firestore emulator, and Pub/Sub emulator locally.

Follow a content job

Trace ingestion, analysis, strategy, production, approval, publishing, and proof.

Meet the agent team

Learn how seven bounded specialists research, plan, write, review, present, and assist.

Operate with confidence

Inspect authority, recovery, observability, replay, deployment, and durable state.

Use exact references

Look up routes, contracts, states, configuration, storage, budgets, and receipts.

The content loop

  1. Ingest an authorized YouTube URL, uploaded video, or operator brief.
  2. Understand the source with Gemini and grounded research.
  3. Strategize with specialist agents that preserve evidence and uncertainty.
  4. Approve the exact strategy and consequential effects through deterministic gates.
  5. Produce reviewed posts, clips, schedules, and content packs.
  6. Publish and verify through official integrations, idempotent commands, receipts, and fresh provider reads.

Built for bounded autonomy

  • Agents judge; code authorizes. Google ADK specialists analyze, plan, write, review, and compose operator surfaces. Application code owns stage transitions, policy, and authority.
  • State survives interruption. Firestore is workflow truth; Pub/Sub delivers resumable work; failures remain visible and recoverable.
  • Approval is payload-bound. A conversational “yes” cannot publish by itself. It opens the same exact confirmation flow used by the dashboard.
  • Effects are idempotent and auditable. Approved actions carry stable identities, produce receipts, and are independently verified.
  • Interfaces stay consistent. Dashboard, conversational chat, and allow-listed Telegram entry points share the same pipeline and approval boundaries.

Explore by role

Evidence and deployment status

Harmonia documents implemented contracts separately from authenticated deployment evidence. Repository tests and local emulator runs prove local behavior only; provider and cloud claims require captured authenticated evidence. The currently reachable Cloud Run revision is a web-only preview and does not prove a deployed worker, Scheduler, Agent Engine invocation, Memory Bank retrieval, or live publish. Use the evidence runbook before presenting deployment, model, publishing, or verification claims.
Start with the quickstart for local inspection. Use configuration and deployment only when you are ready to supply real Google Cloud and platform credentials.
