with hybrid local/cloud routing and recursive coding loops.\n\nInstead of running all agents on the same model, tiered-crew splits work across model sizes: a large model architect plans, and small local models execute.\n\n---\n\n## Core Concepts\n\n- **Senior Tier**: The **Orchestrator** (Manager) manages the process, while the **Architect** builds the project scaffolding with real files and `# TODO` markers.\n- **Junior Tier**: Small local models (vLLM/Ollama) that implement logic inside the `# TODO` regions.\n- **Recursive Loop**: A specialized pattern that scans the AST for TODOs, dispatches Juniors, and runs automated QA (pytest) in a loop until the code passes.\n\n---\n\n## Core Extensions\n\ntiered-crew adds several modules to fill gaps CrewAI does not cover natively:\n\n- **ContextBuilder**: enforces per-agent token budgets and filters KB content.\n- **WorkerRouter**: maps task types to specific LLM workers with automatic cloud-to-local fallback.\n- **Tracer**: records per-run traces to JSONL for latency and token monitoring.\n- **Guardrails**: validates LLM output for truncation, repetition, and valid JSON.\n- **CostTracker**: monitors cloud spend and enforces a per-session USD budget.\n\n---\n\n## Architecture: Recursive Coding Loop\n\n```\nUser request\n     │\n     ▼\n┌──────────────────────────┐\n│  Senior Orchestrator     │ (no
