How are you structuring massive context prompts (codebases & multi-shot AI video) without burning 80% of tokens on noise? Built an open-source Rust tool (repOx) and looking for feedback

One of the biggest problems in prompt engineering right now isn't just how you phrase the instruction — it's context pollution. Even with 200k–1M context windows (Claude, Gemini, GPT, Grok), dumping raw unformatted data into a prompt causes two things: You burn 50,000+ tokens on structural noise. T…
