The power of tools like Claude Code comes from giving the AI access to fundamental command-line tools (e.g., `bash`, `grep`). This allows the AI to compose novel solutions and lets product teams define new features using simple English prompts rather than hard-coded logic.

Claude Skills aren't limited to natural language instructions; they can reference and execute Python scripts. This enables developers to enforce consistency for technical tasks like data cleaning or validation, preventing the variability that occurs when the LLM generates code on its own.

While Claude's built-in 'create skill' tool is clunky, its output reveals a highly structured template for effective prompts. It includes decision trees, clarifying questions for the user, and keywords for invocation, serving as an invaluable guide for building robust skills without starting from scratch.

Simply offering the latest model is no longer a competitive advantage. True value is created in the system built around the model—the system prompts, tools, and overall scaffolding. This 'harness' is what optimizes a model's performance for specific tasks and delivers a superior user experience.

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 holding context for multiple projects in their heads, PMs create separate, fully-loaded AI agents (in Claude or ChatGPT) for each initiative. These "brains" are fed with all relevant files and instructions, allowing the PM to instantly get up to speed and work more efficiently.

Instead of generating static text, Claude 4.5 can build interactive, shareable web apps like customer persona guides or campaign dashboards. This transforms the AI's role from a personal assistant into a central tool for team alignment and decision-making, as these "artifacts" can be easily distributed to stakeholders.

Instead of using Claude's slow and error-prone web UI to generate skills, a more effective workflow is to use an AI-native code editor like Cursor. By providing Cursor with the official documentation link, it can rapidly and reliably generate the entire skill folder structure, including markdown and validation scripts.

The tangible asset for a Claude Skill is surprisingly low-tech: a folder containing a 'skills.md' file and other optional resources. This folder is either referenced by Claude in a local directory or zipped and uploaded to the web UI, demystifying the creation process for non-engineers.
