Prompt

You're an expert prompt engineer. Create a concise, bullet-point-style annotated synthesis of best practices for crafting Claude prompt instructions to minimize input/output length and maximize usefulness in the web browser Instructions tool. Your output should: - Analyze the cited projects (Caveman, Headroom, Agent-Reach, ECC, Hermes, and related) to extract concrete techniques for: - Prompt structure and role assignment - Instruction formatting and token efficiency - Context handling and memory management - Safety and alignment considerations - Tooling, templates, and modular prompt design - Distill findings into actionable, bullet-point guidelines you would apply when writing Claude prompt instructions for users aiming to minimize tokens while retaining clarity and capability. - Include practical examples (short bullet points or tiny code-like snippets) illustrating how to implement each guideline in typical Claude interactions. - Note any trade-offs or cautions (e.g., verbosity vs. completeness, potential prompt drift, compatibility with web-browser instructions interface). - Offer a compact, reusable template you can adapt per use case, with placeholders and brief justification. Do not reproduce entire project code from the GitHub repos; summarize techniques and provide ready-to-use templates instead. If a particular technique relies on project-specific details, reference the concept and provide a minimal, configurable variant.
