To get highly specialized AI outputs, use ChatGPT's "projects" feature to create separate folders for each business initiative (e.g., ad campaign, investment analysis). Uploading all relevant documents ensures every chat builds upon a compounding base of context, making responses progressively more accurate for that specific task.

The all-caps `clod` file, created via the `init` command, stores project structure and user-defined rules. Unlike temporary in-chat instructions that get lost or degraded as the conversation continues, this file is referenced in every session, ensuring consistent behavior and enforcing project-wide guardrails.

Structure AI context into three layers: a short global file for universal preferences, project-specific files for domain rules, and an indexed library of modular context files (e.g., business details) that the AI only loads when relevant, preventing context window bloat.

Claude Code's terminal-based interaction within a specific folder allows it to automatically read and reference local files. This makes "context engineering" drastically faster and more powerful than manually pasting information into a traditional chat interface, as the context is implicitly understood.

Instead of using siloed note-taking apps, structure all your knowledge—code, writing, proposals, notes—into a single GitHub monorepo. This creates a unified, context-rich environment that any AI coding assistant can access. This approach avoids vendor lock-in and provides the AI with a comprehensive "second brain" to work from.

Instead of managing prompts in a separate library, save them as custom commands directly within your Claude Code project folder. This lets you trigger complex, multi-file prompts with a simple command (e.g., `/meeting_notes`), embedding powerful, recurring workflows directly into your development environment.

Instead of overloading the context window, encapsulate deep domain knowledge into "skill" files. Claude Code can then intelligently pull in this information "just-in-time" when it needs to perform a specific task, like following a complex architectural pattern.

Teams maintain a shared `Claude.md` text file in their Git repo. Anytime the AI errs, they add corrections or context to this file. This acts as a constantly improving, team-wide knowledge base that teaches the AI how to work correctly within their specific project, creating a compounding effect.

Run separate instances of your AI assistant from different project directories. Each directory contains a configuration file providing specific context, rules, and style guides for that domain (e.g., writing vs. task management), creating specialized, expert assistants.
