Context Optimizer
nahisahoContext Optimizer is a developer utility that optimizes the context window for long-running sessions and frequent tool invocations, helping manage sessions more efficiently. It issues compression suggestions, reminders, and strong warnings triggered at 50/75/100 invocations and every 25 thereafter, and prompts users to save state via the session manager before compression. PostToolUse hooks after file edits run automatic checks per file extension (e.g., for .ts/.tsx run npx tsc --noEmit, prettier --check, grep to detect console.log), reporting issues and suggesting fixes. PreToolUse hooks prompt for confirmation for installs, builds, git operations, and destructive commands, and suggest using tmux or background execution. A Doc Blocker for Markdown creation asks whether documentation is necessary while considering an exception list. The /mode command injects dev/review/research modes and presents recommended tools and focus areas. Compliant with traceability requirements (REQ-CO-001–006), it improves development efficiency through context savings, safer operations, and automated checks.
