# aws-deployment

Walks your coding agent through AWS CI/CD: CodePipeline, CodeBuild, CodeDeploy, CodeConnections, CodeArtifact. Useful when a pipeline stalls at source or a build hangs in a VPC.

## What it does

The skill hands the agent a map of the AWS build stack. CodeConnections pulls code from GitHub, GitLab or Bitbucket, CodeBuild compiles and tests it, CodeDeploy shifts traffic on EC2, ECS or Lambda, and CodePipeline chains the stages with approval gates in between. What ships is `SKILL.md` plus a `references/` folder split by service: `codepipeline.md`, `codebuild.md`, `codedeploy.md`, `codeartifact.md`, `codeconnections.md`, `troubleshooting.md`.

Most of the content is warnings and failure tables. A connection created with the CLI or CloudFormation sits in `PENDING` forever until someone finishes OAuth in the AWS Console. There is no API-only path. So check the connection status before you start rewriting the pipeline definition.

It pairs with the AWS MCP server for running CLI commands and validating configs, and plain AWS CLI works as well. Cross-account deploys need all three pieces at once: a KMS key policy, an S3 bucket policy and a cross-account IAM role. Miss one and you get `Access Denied` with no hint about which. ECS Fargate, CDK Pipelines, `sam deploy` and GitHub Actions are left to sibling skills on purpose.

## Requirements
- Works with: AWS, GitHub, GitLab

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill aws-deployment -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/aws-deployment/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/aws-deployment/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill aws-deployment -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/aws-deployment/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill aws-deployment -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/aws-deployment/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install aws/agent-toolkit-for-aws aws-deployment
```

2. **Manually: put the files in place**
- File: `.github/skills/aws-deployment/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill aws-deployment -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/aws/agent-toolkit-for-aws --path skills/core-skills/aws-deployment
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/aws-deployment/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add aws/agent-toolkit-for-aws --skill aws-deployment -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/aws/agent-toolkit-for-aws/tree/HEAD/skills/core-skills/aws-deployment/SKILL.md

## When to use it
- wire a CodePipeline from GitHub to ECS
- write a `buildspec.yml` with build caching and Docker
- pick a CodeDeploy strategy: blue/green, canary or linear
- set up a private package registry in CodeArtifact
- trace why a build hangs in a private subnet without NAT

## Example prompts
- Build a GitHub-to-ECS pipeline: CodeConnections source, CodeBuild build, CodeDeploy blue/green
- The pipeline is stuck at Source — check the CodeConnections status
- Set up a cross-account deploy with the KMS key policy, bucket policy and role

# AWS Deploy (CI/CD)

**Works best with** the [AWS MCP server](https://docs.aws.amazon.com/aws-mcp/) for running CLI commands and validating configurations directly. All guidance also works with standard AWS CLI.

## Critical Warnings

**CodeConnections PENDING trap**: Connections created via CLI/CloudFormation remain `PENDING` indefinitely — MUST complete OAuth in the AWS Console. No API-only path exists.

**Cross-account triple requirement**: Cross-account deploys need ALL THREE: (1) KMS key policy granting target account (use key ID, not alias), (2) S3 bucket policy for target account, (3) cross-account IAM role with trust policy. Missing any one = cryptic `Access Denied`.

**CodeDeploy ApplicationStop uses PREVIOUS revision**: Broken stop scripts in a prior deployment block ALL future deploys. Make stop scripts idempotent (exit 0 if service absent). Unblock with `--ignore-application-stop-failures`.

**CodeBuild VPC without NAT**: Builds in VPC subnets without NAT gateway hang at `DOWNLOAD_SOURCE` silently. Private subnets MUST have NAT gateway or VPC endpoints.

**CodeConnections IAM**: Use `codeconnections:` prefix for API calls and IAM policy Actions. Resource ARNs must match exactly — new resources use `codeconnections` prefix, existing resources may use `codestar-connections` prefix. Specify both in Resource if you have mixed-age resources.
```
