A2A Architectures: Tools are not just Functions (The Two-Phase Commit)
Why Agent-to-Agent (A2A) interactions and Side Effects require a 'Two-Phase Commit' for safety.

Chains are brittle. We need a shared state object for robust multi-agent reasoning.

Chat is reactive. Hooks are proactive. We explore how to use Gemini CLI Hooks to inject context and enforce security before the model thinks.

We analyze the JSON-RPC internals of the Model Context Protocol (MCP) and why the 'Context Exchange' architecture renders traditional integration code obsolete.

The software development paradigm is shifting from prompt-and-response to an agentic workflow where developers become coaches, not players, orchestrating AI agent systems for a 100x productivity leap. The key skill is no longer prompt engineering, but Context Engineering - providing agents with structured data, documentation, and instructions. This post provides a practical playbook to build and scale this new agentic SDLC, moving from theory to an implementable strategy for the future of software development.
