The "modern" AI stack has a hidden performance problem: abstraction debt. We have spent the last two years wrapping LLMs in complex IDEs and orchestration frameworks, ostensibly for "developer experience". The research suggests this is a mistake. These wrappers truncate context to maintain low UI latency, effectively crippling the model's ability to perform deep, long-horizon reasoning & execution.

The most performant architecture is surprisingly primitive: - raw Claude Code CLI usage - native Model Context Protocol (MCP) integrations - rigorous context engineering via `CLAUDE.md`

Why does this "naked" stack outperform?

First, Context Integrity. Native usage allows full access to the 200k+ token window without the artificial caps imposed by chat interfaces.

Second, Deterministic Orchestration. Instead of relying on autonomous agent loops that suffer from state rot, a "Plan -> Execute" workflow via CLI ensures you remain the deterministic gatekeeper of probabilistic generation.

Third, The Unix Philosophy. Through MCP, Claude becomes a composable pipe that can pull data directly from Sentry or Postgres, rather than relying on brittle copy-paste workflows.

If you are building AI pipelines, stop looking for a better framework. The alpha is in the metal. Treat `CLAUDE.md` as your kernel, use MCP as your bus, and let the model breathe. Simplicity is the only leverage that scales.

To operationalize this, we must look at the specific primitives Claude Code offers that most developers ignore.

Consider Claude Hooks These aren't just event listeners; they are the immune system of your codebase. By configuring a `PreToolUse` hook that blocks git commits unless a specific test suite passes, you effectively create a hybrid runtime where probabilistic code generation is bounded by deterministic logic. You aren't just hoping the AI writes good code; you are mathematically preventing it from committing bad code.

Then there is the Subagentic Architecture In the wrapper-world, subagents are opaque black boxes. In the native CLI, a subagent is just a child process with a dedicated context window. You can spawn a "Researcher" agent via the `Task` tool to read 50 documentation files and return a summary, keeping your main context window pristine. This manual context sharding is the key to maintaining "IQ" over long sessions.

Finally, `settings.json` and `CLAUDE.md` act as the System Kernel While `CLAUDE.md` handles the "software" (style, architectural patterns, negative constraints), `settings.json` handles the "hardware" (permissions, allowed tools, API limits). By fine-tuning permissions and approved tools, you create a sandbox that is both safe and aggressively autonomous.

The future isn't about better chat interfaces. It's about "Context Engineering" designing the information architecture that surrounds the model. We are leaving the era of the Integrated Development Environment (IDE) and entering the era of the Intelligent Context Environment.
