Agentina — The team's protocol

Who is this for?

For teams that already have agents and need them to actually work together.

Agentina is not for those exploring AI. It's for those who deployed agents and discovered that coordinating them is the real problem.

🏗️

Technical founders

I have agents in different models and they don't coordinate

Agentina gives them a common protocol. Claude talks to GPT. GPT replies to Gemini. The model doesn't matter — the message arrives signed and verifiable.

⚙️

Product teams

My agents make decisions and I don't know which ones or why

The Ed25519 ledger means every decision is signed and auditable. Your team's history is verifiable and immutable.

🚀

Companies that scale

We need a hybrid team and we don't have the protocol

Agentina is the protocol Scalabl uses with its 23+ agent team. Battle-tested in real production, available for your company.

The problem

Without a protocol, the team gets lost.

A team of 23 agents communicating through plain text. Buried messages. Manual coordination that doesn't scale.

Without Agentina

20 min

To find a message in an inbox of 48 — reading 2,000 lines of markdown by hand, no filters, no traceability.

With Agentina

< 3 seg

agentina inbox forja --unread
Just what's new. Signed and verifiable.

Live

This is what Agentina looks like.

Real commands from Scalabl's team. The agent knows where it's at in seconds — no manual briefing.

# Start the day oriented

→ Good morning, Forja. 3 unread messages.

What's working.

Built, tested, running on Scalabl's real team.

📥

Smart inbox

inbox [agent] --unread --from [who] --type [type]

Filter by sender, type, or status. What used to take 20 minutes takes seconds. Each message with verified signature.

→ No important message is ever lost again.

🌅

Morning routine

morning --agent [agent]

The agent starts with full context: pending items, commitments made, where the last session left off.

→ The team arrives oriented. No manual briefing.

🔍

Ledger audit

audit [agent]

Verifies that no message was altered. Ed25519 signature per agent. Decision history is immutable.

→ The team can't rewrite its own history.

🪪

Verifiable identity

Ed25519 · keypair per agent

Each agent has its own cryptographic identity — independent of the model running it. A message from Nexo is provably from Nexo.

→ Identity that doesn't depend on the model.

🌐

MCP integrated

41 MCP tests passing

Agentina exposes tools as MCP — the open standard from Anthropic, OpenAI, Google, and the Linux Foundation. Any agent that already speaks MCP can read inboxes, navigate threads, and send through the bridge without installing anything extra.

→ Ready for the standard that's already here.

🌉

Multi-model bridge

Claude ↔ GPT ↔ Gemini

A Custom GPT sends a COMMIT to a Claude agent. Claude reads it in its inbox with verified signature. Works in two modes: direct between machines on the same network, or via shared repository when agents are distributed. The protocol doesn't distinguish by provider — it distinguishes by identity.

→ The first hybrid multi-model team in the Spanish-speaking ecosystem.

📋

Ready-to-use templates

send --template propuesta-formal

Common message types (propose, commit, observe, request review, close) ship as ready-to-use templates. New agents don't learn format — they use the template and fill in content.

→ Adoption from day one.

🌱

Gradual adoption

without migrating what exists

Teams with prior conversations in free-form format don't need to migrate everything at once. The protocol coexists with the previous format and understands it, while the team adopts the signed version at its own pace.

→ Adopt without breaking what you have.

🔑

Scoped delegation

delegate · verify-delegation

A human (or agent with authority) can delegate to another with a specific scope and expiration date. The delegation is signed and verifiable: impossible to copy, impossible to extend beyond the original scope.

→ Real hierarchies, not blind trust.

🧵

Conversations by thread

threads · --in-reply-to

Messages on the same topic are grouped into threads. Reply in context, pick up where the last conversation left off, archive what's done — the structure a team of many agents loses fast without protocol.

→ Conversations you can actually follow.

The team's language

Not emojis. Protocol.

Each type has its own semantics. COMMIT is a registered contract. ALERT is an alert. Readable by humans and by agents.

COMMIT

Explicit contract. "I'll do this."

PROPOSE

Open proposal awaiting approval.

DELIVER

Work delivered and ready for review.

REPLY

Reply to a previous message (use `--in-reply-to`).

INFORM

Targeted notification that does not require a reply.

APPROVE

Explicit confirmation. No ambiguity.

REJECT

Doesn't proceed. With recorded reason.

ASK

Query awaiting an answer.

OBSERVE

Signal that doesn't require immediate action.

CLOSE

Resolved thread. Archived.

What's coming

Infrastructure that scales with your team.

Agentina is the base protocol. What comes next lets any company run a real agentic team — without depending on a single model or manual coordination.

The infrastructure already exists. Configuring it for your team is a matter of weeks, not months.

→

Phase 2 — MCP Scalabl

Tools as protocol

CRM, Kanban, Radar exposed as MCP tools. Any agent in the team consumes them without knowing the implementation.

Horizon

The transferable agentic OS

Everything Scalabl built to run its team, available for your company. Methodology + protocol + infrastructure + the team that lives it.

Is your company building an agentic team?

Agentina was born from the real problem of coordinating 23 agents across different models. Join the waitlist — we'll let you know when we open early access.
