This covers building that kind of process on AWS Lambda, where state is kept for you, failed steps retry, and a workflow can pause and wait. Reach for it when one function call is not enough. ### Top 3 things it does for you - Build a multi-step process that keeps its place if it fails - Add retries and rollback to a workflow - Pause a workflow while it waits for a person ## Information **AWS Lambda durable functions at a glance** | | | | --- | --- | | Kind | Skill | | Publisher | [Amazon Web Services](/@aws) | | Category | [IT & Ops](/category/ops) | | Works with | Agent Skills - an open standard supported by 40+ agents | | Version | 1 | | Size | 122 KB | | Licence | Apache-2.0 | | Repository | [aws/agent-toolkit-for-aws](https://github.com/aws/agent-toolkit-for-aws/tree/eb96852087e2b2757b67d358d6d38c17c5c28205/skills/specialized-skills/serverless-skills/aws-lambda-durable-functions) | | GitHub stars | 2,420 (as of Nov 2026) | | Installs | 6,260, counted by skills.sh (Nov 2026) | ## Security report **Verified.** AIR scanned this exact version of AWS Lambda durable functions and flagged nothing.

It covers the replay model that all of this rests on, step operations, wait and callback patterns, error handling with the saga pattern, and testing with LocalDurableTestRunner. It comes up around durable execution and workflow orchestration, state machines, retry and checkpoint patterns, long-running stateful Lambda functions, human-in-the-loop callbacks, and the API surface itself - context.step, context.wait, context.invoke, context.runInChildContext, withDurableExecution, DurableContext, UnrecoverableInvocationError, the durable-execution-sdk, qualified ARN invocation and durable handler replay. ## What's inside - SKILL.md - instructions - references/advanced-error-handling.md - reference - references/advanced-patterns.md - reference - references/concurrent-operations.md - reference - references/deployment-iac.md - reference - references/error-handling.md - reference - references/getting-started.md - reference - references/replay-model-rules.md - reference - references/step-operations.md - reference - references/testing-patterns.md - reference - references/troubleshooting-executions.md - reference - references/wait-operations.md - reference ## Questions ### Is AWS Lambda durable functions safe to install? AIR scanned this exact version of AWS Lambda durable functions and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit eb96852087e2, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/aws-lambda-durable-functions. ### How do I install AWS Lambda durable functions?
