Context Engineering Kit: Memory Layer + Design System for AI Agents

The Opportunity

A context engineering kit for developers using Claude Code, Codex, or Cursor. Includes templates (AGENTS.md, SOUL.md patterns), implementation guides, and a context testing tool. The "Context Engineering" category is forming now — whoever names it and publishes the authoritative resource owns the SEO. LangWatch (1,091 bookmarks) confirmed the market wants agent observability.

Why This Fits

Five independent subreddits (cursor, codex, ClaudeAI, ChatGPT, reddit) all report the same pain: context management breaks long tasks. The "1M context window is a trap" insight shows the market now understands the problem is management, not size. The kit can be built from existing patterns — zero infrastructure needed. Monetize: open-source the templates, sell the course/consulting.

Cross Validation

5 subreddits + PH launch + LangWatch (1091 bk) + '1M context trap' + Cursor DIY workaround = SEVEN signals. The '1M context trap' is new: the market already knows the problem is MANAGEMENT, not size. First time this formulation appears — window to be the one that names the solution.
