Before the first prompt: Code execution paths in trusted coding-agent projects

Datadog researchers show that Codex MCP configs and Claude Code settings allow repository-controlled code to run before any user prompt — an overlooked supply-chain vector in AI-assisted development.

Learn how trusted coding-agent projects can execute repository-controlled code before the first prompt through Codex MCP configuration and Claude Code environment settings.

Editorial Analysis

Why it matters

Enterprises rapidly adopting AI coding agents face a pre-prompt execution risk that bypasses traditional code-review gates, effectively turning trusted repos into attack staging areas.

What to do

Audit all AI coding-agent configurations for pre-prompt code execution paths and enforce strict allowlisting before connecting agents to internal repos.

Board brief

AI coding assistants can execute untrusted code before a developer even types a prompt — a new supply-chain risk that needs governance now.
