Complete procedures with a way back.

Create a durable Node.js chatbot with OpenAI Conversations, typed response streaming, safe cancellation, transcript recovery, duplicate protection, explicit retention and deletion, real failure drills, and a production release gate.

Build a runnable native OpenAI Responses and Claude Messages router for an explicitly limited non-streaming text contract, with strict unsupported-feature rejection, provider-specific adapters, durable turn idempotency, native evidence, sanitized errors, timeout reconciliation, live parity fixtures, tenant canaries, and rollback without replay.

Build a bounded Responses API agent whose strict function calls are treated as proposals, whose deterministic state and policy select eligible tools, whose consequential actions require exact human approval, and whose adapters use durable idempotency, effect-aware retries, deadlines, safe outputs, correlated audit and full-bundle rollback.

Create an owned prompt registry that safely references OpenAI reusable prompts from the Responses API, validates typed variables, pins platform versions, proves consumer compatibility, evaluates candidates, and supports controlled promotion and complete rollback.

Engineer a production prompt as a versioned, evidence-grounded application contract with explicit instruction hierarchy, safe abstention, representative evals, deterministic gates, controlled rollout, observability, and atomic rollback.

Connect models to real capabilities with strict schemas, deterministic policy, human approval, idempotent execution, bounded retries and complete audit evidence.

Design, validate, evaluate and operate schema-constrained OpenAI responses without confusing valid JSON with factual truth or authorization.
