HUMAN-IN-THE-LOOP · AI AGENT SAFETY

The Off Switch for AI Agents.

AI agents are moving fast. Haltio makes sure they stop when it matters — and only when it matters.

THE PROTOCOL

Three lines of code. Full human oversight.

import haltio

haltio.configure(
    slack_webhook_url="https://hooks.slack.com/...",
    agent_id="MyAgent-01",
    timeout_seconds=300,
)

approved = haltio.checkpoint(
    task="Delete production database",
    description="Drops all tables — triggered by cleanup script",
    risk_level="HIGH",  # LOW, MEDIUM, or HIGH
)

if approved:
    run_dangerous_action()
else:
    print("Action blocked by human.")
01
Mark the checkpoint
Tag any agent action with haltio.checkpoint(). Assign LOW, MEDIUM, or HIGH risk.
02
Human gets notified
Slack pings with full context. A browser dashboard shows the pending decision in real time.
03
Agent waits, then acts
If approved, the task runs. If rejected or timed out, it's blocked automatically. Every decision is logged.
THE PROBLEM

AI agents are executing actions you haven't reviewed.

Modern AI agents can send emails, delete files, call APIs, and deploy to production. Most teams have no mechanism to pause an agent before a critical action. Manually reviewing every task isn't scalable. Ignoring oversight entirely is how incidents happen.

"The average enterprise AI pilot fails not because the agent is wrong — but because teams don't trust it enough to deploy."

Unchecked agent actions

Without checkpoints, agents can delete data, send incorrect emails, or make expensive API calls with no human review.

Approval fatigue is real

Existing solutions require humans to approve every single step. Teams abandon oversight entirely within days.

Enterprise trust gap

Enterprises need audit trails, not just automation. No oversight layer = no enterprise deployment.

HOW HALTIO SOLVES IT

Selective oversight. Not surveillance.

Risk-Level Routing

Tag tasks LOW, MEDIUM, or HIGH. Only what you flag as important ever reaches a human. Everything else runs automatically.

Slack-Native Alerts

Operators get rich Block Kit notifications the moment a checkpoint fires. Context, risk level, and approve/reject buttons — right in Slack.

Browser Dashboard

A real-time approval dashboard shows every pending, approved, rejected, and timed-out action with full audit history.

Auto-Timeout Failsafe

No response within 5 minutes? The action is automatically blocked. Agents never hang indefinitely waiting on humans.

2-Minute Integration

Add Haltio to any existing Python AI agent with 3 lines of code. No infrastructure changes. No new services to run.

Full Audit Log

Every checkpoint decision — who approved it, when, and why it was flagged — is logged to approvals.json. Compliance-ready.

You decide what needs a human.

LOW — Auto-Approved Instantly

Logged to the dashboard but executes without interruption. Use for read operations, logging, low-impact writes.

risk_level="LOW"

MEDIUM — Paused, Needs Approval

Agent stops and sends a Slack notification. Human approves or rejects via dashboard. Timeout: 5 minutes.

risk_level="MEDIUM"

HIGH — Urgent Human Override Required

Red pulsing card in dashboard. Slack alert fires immediately. Same timeout, higher visual urgency. Use for destructive or irreversible actions.

risk_level="HIGH"

MARKET TIMING

The agentic AI wave is here. Governance infrastructure isn't.

As frameworks like LangChain, AutoGen, and CrewAI push AI agents into production pipelines, teams are shipping autonomous systems with no meaningful pause mechanism. Haltio is positioning itself as the standard approval SDK — the equivalent of a circuit breaker for agentic systems. First-mover advantage in a space with no established leader.

THE BUSINESS

SDK today. Platform tomorrow.

The open-source SDK creates developer adoption and trust. The paid layer is an enterprise dashboard with team-based approvals, SSO, RBAC, SOC 2 audit exports, and SLA guarantees. This is the Sentry playbook — start with a tool developers love, expand into enterprise compliance infrastructure.

Built by developers. Validated by the market.

★★★★★
"We had a LangChain agent deleting S3 buckets in staging without anyone noticing for two days. After integrating Haltio, every HIGH-risk file operation requires my sign-off. Setup took literally 4 minutes."

★★★★★
"The Slack integration is the killer feature. I don't have to babysit a dashboard — the alert comes to me with full context and I approve or reject in one click. It changed how we think about agent deployment."

★★★★★
"We evaluated six 'human-in-the-loop' tools. All of them required us to rebuild our agent architecture. Haltio dropped in with zero refactoring. That alone sold it."
