feat(aws-serverless): add aws-lambda-microvms skill - #202
Merged
bfreiberg merged 5 commits intoJun 23, 2026
Conversation
Add the AWS Lambda MicroVMs skill to the aws-serverless plugin, covering building, running, debugging, and operating Firecracker-isolated, snapshot-resumable MicroVM applications: lifecycle and suspend/resume, networking and connectors, IAM and security, snapshots/uniqueness, and troubleshooting. Frontmatter follows the repo skill-frontmatter schema (description, argument-hint, metadata.tags). Register microvms/firecracker keywords in the plugin manifests (.claude-plugin, .codex-plugin) and the root marketplace entry, and bump the aws-serverless plugin version to 1.2.0.

There was a problem hiding this comment.
Approved; noted that docs need to be updated re: sts:TagSession not being required and HTTP_INGRESS being a supported ingress type.
- Use full image ARN (colon-form microvm-image:name) consistently for --image-identifier across SKILL.md and all references; the bare name is rejected by the API. - Normalize --image-version to the full major.minor string (1.0). - Align the trust-policy SourceArn to the colon ARN form. - Point the regional-availability step at the concrete list-managed-microvm-images command. - Clarify idlePolicy is optional but its fields are required when supplied, and that maximumDurationInSeconds is a separate RunMicrovm flag. - Reword the /ready and /validate hook timeout guidance to remove the self-contradictory phrasing.

main already advanced aws-serverless to 1.2.0 via the aws-lambda-microvms skill (awslabs#202). Bump this PR to 1.3.0 to avoid a duplicate-version collision; the LMI region/scheduled-scaling additions are backward-compatible features (minor bump from 1.2.0).

…uled scaling (#201) * docs(aws-serverless): update LMI skill for region expansion and scheduled scaling - Region availability: now all commercial AWS Regions except Israel (Tel Aviv), Middle East (Bahrain), Middle East (UAE), and Asia Pacific (Auckland); update Unsupported Region handling. - Scheduled scaling: document EventBridge Scheduler-based scheduled scaling of Min/Max execution environments for predictable traffic (SKILL.md, configuration-guide.md, infrastructure-setup.md). * Add migration assessment formulas and fix LMI configuration defaults - Add formulas for deriving MaxConcurrency, MemorySize, and MinExecutionEnvironments from Lambda Insights metrics (cpu_total_time, memory_utilization, ConcurrentExecutions) - Add fallback guidance when Lambda Insights is not available - Add Lambda Insights enablement instructions - Fix default memory-to-vCPU ratio from 4:1 to 2:1 (matches public docs and CDK defaults) - Fix weighted alias traffic shifting claim (not currently supported for LMI) - Add testing phase troubleshooting guidance (CPUThrottles, MemoryThrottles, DiskThrottles, ConcurrencyThrottles, low CPU utilization) - Update Best Practices to align with corrected defaults * docs(aws-serverless): fix Lambda Insights link and troubleshooting.md formatting Follow-up to the migration-assessment PR: correct the broken Lambda Insights versions doc URL and add blank lines around lists in troubleshooting.md so dprint/markdownlint pass. * chore(aws-serverless): bump plugin version to 1.2.0 Region expansion + scheduled scaling + migration-assessment guidance are backward-compatible feature additions to the LMI skill (minor bump). Updated plugin.json, .codex-plugin/plugin.json, and marketplace.json. * fix(aws-serverless): cap LMI MemorySize formula at 32 GB maximum Address review feedback: the MemorySize derivation had a floor (max with 2048) but no ceiling, so it could exceed the 32 GB LMI limit. Wrap in min(32768, ...) to cap at the maximum. * chore(aws-serverless): bump version to 1.3.0 main already advanced aws-serverless to 1.2.0 via the aws-lambda-microvms skill (#202). Bump this PR to 1.3.0 to avoid a duplicate-version collision; the LMI region/scheduled-scaling additions are backward-compatible features (minor bump from 1.2.0). --------- Co-authored-by: Alain Krok <alkrok@amazon.com> Co-authored-by: Craig Phillips <pcrai@amazon.com>

What
Adds the aws-lambda-microvms skill to the
aws-serverlessplugin.AWS Lambda MicroVMs combine Firecracker VM isolation with container-like efficiency — snapshot-resumable, suspend/resume, dedicated HTTPS endpoint, up to 8-hour lifetimes. The skill covers building, running, debugging, and operating MicroVM applications across six references: getting started, lifecycle model, networking/connectors, IAM and security, snapshots and uniqueness, and troubleshooting.
