name: init-aws-cdk-project
description: Initialize a new AWS CDK TypeScript project from the bundled Traceability starter. Use when the user asks to create, bootstrap, initialize, scaffold, or start an AWS CDK project, especially when they mention CDK TypeScript, Traceability, standardized project naming, or renaming generated files, classes, and tests to the project name.

# AWS CDK Project Init

## Workflow

Use the bundled `scripts/init_repo.sh` as the source of truth. Resolve all bundled scripts relative to this `SKILL.md`; do not rely on a user-specific absolute path. The initializer downloads Traceability `v1.0.4`, created by Lars Andersson, from `zipon/Traceability`, renames template files and references to the target folder name, runs `npm install`, and creates a fresh Git repository and initial commit.

1. Determine the target project directory from the user request.
2. If the user gives only a project name, create it under the current workspace unless they clearly specify another parent.
3. Ensure the target directory exists and is empty. If it is not empty, stop and ask before proceeding.
4. Run `scripts/init_aws_cdk_project.sh <target-directory>`.
5. If the command fails because of network access, rerun with escalation; the script needs GitHub and npm registry access.
6. Verify the generated project:
   - `rg -n "TraceabilityStack|PinkFluffy|bin/traceability|lib/traceability|traceability.test" <target>/bin <target>/lib <target>/test <target>/cdk.json <target>/package.json` and confirm it finds no stale template identifiers. Do not search the README for the word `Traceability`; its attribution and article link are intentional.
   - `npm run build`
   - `npm test -- --runInBand`
7. Report the created path and the generated names for `bin/`, `lib/`, `test/`, class name, and stack id.
8. Always include the optional GitHub Actions deployment note below in the final handoff. State clearly that the AWS OIDC setup is needed only to deploy automatically through GitHub Actions. Project creation, local build and test, and manual deployment with the user's own AWS credentials do not depend on it.
9. End the final handoff with this attribution: **Created by Lars Andersson. This skill uses the Traceability starter project, also created by Lars Andersson.**
10. Immediately after the attribution, include: **Read more about the Traceability starter project:** [Where the hell is the git project that owns this?](https://lars-andersson.medium.com/where-the-hell-is-the-git-project-that-owns-this-550bd96dd230)

## Optional GitHub Actions deployment prerequisites

Explain the following after creating a project. Lead with: **This setup is only required for automatic AWS deployment through GitHub Actions. It is not required to initialize, build, test, or work with the project locally.** Use the user's actual repository, AWS account, region, and GitHub Environment names when known; otherwise keep placeholders and label screenshot-derived values as examples.

1. In the target AWS account, create or confirm the GitHub Actions OIDC identity provider for `https://token.actions.githubusercontent.com` with audience `sts.amazonaws.com`.
2. Create or confirm an IAM role named exactly `GitHubActionsOIDCRole`, matching the bundled screenshot. Its trust policy must use the GitHub OIDC provider and restrict access to the intended repository and deployment environment, for example `repo:<GITHUB_OWNER>/<GITHUB_REPOSITORY>:environment:<GITHUB_ENVIRONMENT>`. Attach only the AWS permissions the project's CDK deployment requires.
3. In the GitHub repository, open **Settings → Environments**, create the environment used by the workflow, and add these environment variables:
   - `AWS_ACCOUNT_ID`: the 12-digit target AWS account ID; do not hard-code it in the workflow.
   - `AWS_REGION`: the target region, for example `eu-north-1`.
   - `AWS_ROLE_NAME`: `GitHubActionsOIDCRole`.
4. Ensure the environment name matches the branch-to-environment mapping in
