Self-healing agent pipelines: automatic rollback and retry orchestration

# Self-healing agent pipelines: automatic rollback and retry orchestration When agents touch real systems, reliability is table stakes. This blueprint shows how to design self-healing pipelines with automatic rollback and budget-aware retries at the MCP boundary. ## Control loops, not one-shot calls - Wrap tool invocations in feedback loops that check invariants and roll back on drift. ## Typed error classes → retry policy - Map `retryable`, `auth`, `validation`, and `quota` to backoff strategies. - Add dead-letter queues for human review when retries exhaust. ## Budget-aware execution - Track time and spend per task; abort or degrade gracefully when budgets burn down. ## Shadow + canary for prompts and tools - Shadow new prompts; canary new tools/routes and roll back on regression. ## Transactional sequences - Use two-phase effects when possible: `plan → confirm → commit`. - Persist checkpoints; resume idempotently after failures. --- Self-healing isn’t magic—it’s discipline. Encode it at the protocol edge and your agents will keep shipping even when the world gets messy.
