The Tools

Agentic Coding Tools Are Not Autocomplete

These tools plan multi-step workflows, invoke shell commands, access file systems, and coordinate across repositories. They are autonomous agents, not suggestion engines. That power requires the right configuration.

Claude Code

Anthropic

CLI agent and VS Code extension using Claude models. OS-level sandboxing via Linux bubblewrap and macOS seatbelt. Mandatory tool confirmation by default. Lowest vulnerability rating among major tools.

  • Codebase understanding and multi-file editing
  • Multi-agent coordination and session management
  • AWS Bedrock, GCP Vertex AI, or direct API
  • SOC 2 Type II, ISO 27001, ISO/IEC 42001

Codex CLI

OpenAI

Open-source Rust-based CLI agent using OpenAI models. Three sandbox modes (read-only, workspace-write, full access) with OS-level enforcement. Available through Azure OpenAI Service.

  • Apache-2.0 open source (63.9K GitHub stars)
  • Seatbelt (macOS) and Landlock+seccomp (Linux)
  • MCP server support and multi-agent collaboration
  • Azure OpenAI Service or direct API

Gemini CLI

Google

Open-source CLI agent using Gemini models with a ReAct (Reason and Act) loop. Docker and Podman sandboxing. Available through GCP Vertex AI with Private Service Connect.

  • ReAct loop with MCP server support
  • Docker/Podman and macOS Seatbelt sandboxing
  • GCP Vertex AI with VPC Service Controls
  • Google Workspace integration

Security

Not All Tools Are Created Equal

Research shows 85%+ prompt injection success rates against some popular coding tools. Vendor security varies dramatically. Claude Code achieves the lowest vulnerability classification ("Low") due to mandatory tool confirmation and sandboxed MCP servers by default. Cursor and Copilot are rated "Critical" and "High" respectively.

We help you select tools based on security posture, not marketing. For regulated environments, the choice of tool matters as much as the choice of cloud platform. We configure OS-level sandboxing, permission models, and approval policies that match your risk tolerance.

OS-level sandboxing

Claude Code uses Linux bubblewrap and macOS seatbelt for kernel-level isolation. Codex CLI uses Landlock+seccomp. These are not application-level controls; they are enforced by the operating system.

Permission models

Configurable approval policies for file writes, shell execution, and network access. No auto-approve for sensitive operations. Human confirmation required before potentially destructive actions.

Tool whitelisting

We help you define which tools are approved, which are prohibited, and why. Not every agentic tool meets the security bar for regulated environments.

What You Get

From Tool Selection to Team Mastery

We cover the full path: choose the right tools, configure them securely, and train your people to use them effectively.

Tool Assessment & Selection

Evaluate Claude Code, Codex CLI, Gemini CLI, and other agentic tools against your security requirements, cloud platform, and team needs. Vendor-neutral recommendation based on evidence, not preference.

Secure Configuration

Configure sandbox modes, permission policies, and approval workflows for each tool. Integrate with your enterprise AI infrastructure and governance policies.

Hands-On Workshops

Teams work with Claude Code, agentic workflows, and prompt engineering on real problems from their own practice. Not slide decks. People leave each session with skills they use immediately.

Rapid Prototyping Sprints

Bring a real business problem. We build a working solution in one to two days using agentic tools. The prototype proves (or disproves) the concept before any larger commitment.

Train-the-Trainer

Build internal champions who can sustain adoption after our engagement ends. We transfer knowledge, not create dependency. Your team owns the capability.

Kelvin Training Platform

Our proprietary training platform provides safe environments for teams to experiment with prompt construction, model behavior, and agentic patterns.

Why 273 Ventures

We Use These Tools Every Day

Daily practitioners

We build Kelvin Agentic OS and Kelvin Intelligence using Claude Code and agentic workflows daily. Our training comes from real production use, not vendor demos.

Deep security research

We maintain comprehensive deployment guides for Claude Code on AWS Bedrock, Codex CLI on Azure OpenAI, and Gemini CLI on GCP Vertex AI. We know the security models inside and out. Read our guide: Deploying Claude Code Safely in Your Law Firm.

Published frameworks

Our Agentic AI in Law and Finance textbook defines the GPA Framework for analyzing any agentic system. We teach from published, peer-reviewed research.
