Found a Rust TUI coding agent that aggressively trims context with AST-level chunking. Cut my token bleed sharply with DeepSeek V4 Flash.

Been hunting for a coding agent that doesn't dump my entire directory tree into every prompt. found vtcode on github - open-source rust tui, surprisingly aggressive on context management. what makes it different from the usual agent frameworks: most shovel the whole codebase context into prompts and burn tokens fast. vtcode goes the opposite way - explicit token budget tracking plus ast-level context extraction via ripgrep + ast-grep. only the structurally relevant code chunks get sent to the model. on my refactor tasks the prompt size dropped sharply.
