# Agent Engineering ## Coverage - The discipline's relationship to and distinction from prompt engineering, harness engineering, and traditional distributed systems - The four pillars: architecture and lifecycle management, task decomposition and context management, multi-agent coordination patterns, production reliability - The lifecycle state machine: claim → execute → verify → commit → release, with the extended research/plan/review variant for complex workflows - Context health states (ok / degraded / compact / exhausted) and their budget thresholds, plus the six observable signals of context rot - Multi-agent coordination patterns: orchestrator/worker, fan-out/merge, evaluator/optimiser, consensus/fusion, sequential chain, hybrid — and the cost/reliability trade-offs of each - The two-pass pattern (audit then fresh-context implement) for reliability-critical workflows - The eight named coordination failure modes (task stealing, context contamination, merge conflicts, silent stall, brief rot, result injection, context bloat, double-commit) with detection and mitigation - The six production reliability requirements: observability, cost budgets, idempotency, failure recovery, safety caps, claim locks — and what breaks when each is missing - The delegation decision framework: six gates with overhead crossover analysis (≈1000-token minimum subagent overhead), batch crossover at four tasks for cheap-model fan-out - The most common anti-patterns (God Agent, prompt-as-architec
