name	setup-aws-accounts
description	Provision the multi-account AWS environment a Lisa CDK project deploys into, using the @codyswann/aws-soc2-setup CLI (AWS Organizations, Control Tower, IAM Identity Center, SOC 2 controls). Use when a CDK project still has PLACEHOLDER account IDs in config/environments.ts, when asked to create the dev/staging/production/shared AWS accounts, or when CDK deploys fail because accounts, SSO profiles, or bootstrap are missing. Drives the CLI for the org + OU + security foundation and Account Factory account vending, writes the AWS SSO profiles the project's scripts expect, runs cdk bootstrap with cross-account pipeline trust, replaces PLACEHOLDER account IDs, sets the AWS_ACCOUNT_ID_* GitHub secrets when CI uses them, and records the account map in .lisa.config.json. Idempotent — safe to re-run. Console-only prerequisites (root MFA, enabling Identity Center, creating the Control Tower landing zone) are surfaced as an explicit human checklist, never automated.

Setup AWS Accounts (SOC 2 Landing Zone)

Provision and wire the AWS accounts a CDK project deploys into. The account supply side runs through the @codyswann/aws-soc2-setup CLI (AWS Organizations, Control Tower, IAM Identity Center, security services, SOC 2 controls); the demand side — profiles, cdk bootstrap, config files, CI secrets — is wired by this skill so the project goes from PLACEHOLDER account IDs to deployable in one flow.

When to use

• A CDK project's config/environments.ts still has accountId: "PLACEHOLDER" entries, so cdk deploy silently skips those environments.
• The user asks to "create the AWS accounts", "set up dev/staging/production accounts", "bootstrap AWS for this project", or similar.
• scripts/pre-deployment-checklist.sh fails because <prefix>-<env> AWS profiles don't exist or don't authenticate.
• A fresh organization needs the SOC 2 foundation (Control Tower, guardrails, security services) before workload accounts are vended.

Not for: deploying stacks (that's cdk deploy / CI), or GitHub repo governance (that's lisa-setup-github-repo).

How the CLI behaves (read before scripting it)

• Invoke as npx -y @codyswann/aws-soc2-setup@1 <command>. Pin at least the major version — an unpinned npx pull is a supply-chain risk for a tool that runs with management-account credentials. Always set NO_COLOR=1 so output parses cleanly.
• It is an actuator, not an API — no --json output. Drive it for side effects, then read authoritative state back with the plain aws CLI (aws organizations list-accounts, aws sts get-caller-identity). Never trust scraped text alone for account IDs.
• It is idempotent per resource (ensure-semantics against live AWS), so re-running setup is safe — except controltower provision-account, which is not deduped by name. Always check aws organizations list-accounts before provisioning and skip accounts that already exist.
• --dry-run previews every mutating command; status and whoami are read-only.
• controltower provision-account -o takes the OU name (e.g. Workloads); register-ou and enable-controls take the OU id/ARN. Don't mix them up.

Step 1 — Assess the environment (read-only)

NO_COLOR=1 npx -y @codyswann/aws-soc2-setup@1 whoami -p <management-profile> -r <region>
NO_COLOR=1 npx -y @codyswann/aws-soc2-setup@1 status -p <management-profile> -r <region>

status reports five independent checks: credentials, Organizations, recommended OUs, IAM Identity Center, member accounts.

The human gate. Three prerequisites are console-only and must never be automated. If status shows Identity Center or the landing zone missing, stop and present this checklist in plain language a non-technical operator can follow, then end the run:

1. Sign in to the AWS console as the account root user and enable MFA on the root account.
2. In the console, enable IAM Identity Center (in your home region).
3. In the console, create the AWS Control Tower landing zone (this creates the Audit and Log Archive accounts; takes ~30–60 minutes).
4. Configure a management-account admin profile locally: aws configure sso (interactive).

Re-run this skill after those are done — Step 1 will pass and the flow continues from wherever it left off.

Step 2 — Gather inputs

Collect (via arguments if provided, AskUserQuestion otherwise; use stated defaults when running unattended):

Input	Default	Notes
Management profile	AWS_PROFILE	Must be the org management account
Region	us-east-1	Match the project's config/environments.ts
Profile prefix	project name from package.json	Matches AWS_PROFILE_PREFIX used by scripts/pre-deployment-checklist.sh
Environments	dev, staging, production, shared	shared hosts the pipeline and gets cross-account trust
Root email pattern	ask — no safe default	Each account needs a unique root email; suggest plus-addressing: aws+<prefix>-<env>@<domain>
Identity Center username	ask — no safe default	The Identity Store user that gets AWSAdministratorAccess on each new account in Step 5; verify it exists (create with sso create-user if not)
Identity Center start URL	from status output or the console	The full sso_start_url for the sso-session block in Step 5 (default form https://<domain>.awsapps.com/start, but custom domains differ — never reconstruct it from parts)

Step 3 — Foundation (org, OUs, controls, security services)

Show the plan, get explicit approval, then apply:

NO_COLOR=1 npx -y @codyswann/aws-soc2-setup@1 setup --dry-run -p <mgmt> -r <region>

Present the dry-run output and stop for confirmation before mutating the organization — AskUserQuestion when interactive, or an unambiguous apply/confirm argument from the caller when running unattended. Silence is not approval. Only then:

NO_COLOR=1 npx -y @codyswann/aws-soc2-setup@1 setup -p <mgmt> -r <region> \
  [--ou <workloads-ou-id>] [--central-account <id>] [--admin-account <id>] [--audit-account <id>]

This ensures the organization, creates the Infrastructure/Workloads/Sandbox OUs, enables the security services (GuardDuty, Security Hub, Config, …), conformance packs, and — when --ou is passed — registers the OU with Control Tower and enables the SOC 2 control baseline. Safe to re-run.

Step 4 — Vend the workload accounts

For each environment, first check it doesn't already exist:

aws organizations list-accounts --profile <mgmt> \
  --query "Accounts[?Name=='<prefix>-<env>'].{Id:Id,Name:Name,State:State}" --output table

(Use State, not Status — AWS is retiring the Status field in favor of State.)

Then provision the missing ones, one at a time, each with a unique root email. Stage accounts go into the Workloads OU:

NO_COLOR=1 npx -y @codyswann/aws-soc2-setup@1 controltower provision-account \
  -p <mgmt> -r <region> \
  -n <prefix>-<env> -e aws+<prefix>-<env>@<domain> -o Workloads --wait

The shared (pipeline) account goes into Infrastructure instead:

NO_COLOR=1 npx -y @codyswann/aws-soc2-setup@1 controltower provision-account \
  -p <mgmt> -r <region> \
  -n <prefix>-shared -e aws+<prefix>-shared@<domain> -o Infrastructure --wait

--wait polls Account Factory (~minutes per account) and prints New account ID: <id>. After all accounts finish, harvest the authoritative env → account-ID map from aws organizations list-accounts — that map drives every later step.

Step 5 — Identity Center access + local AWS profiles

Grant the operator admin on each new account, using the Identity Center username collected in Step 2:

NO_COLOR=1 npx -y @codyswann/aws-soc2-setup@1 sso assign \
  -p <mgmt> -u <username> -a <account-id> -r AWSAdministratorAccess

(or sso group -g <prefix>-admins --all-users -a <account-id> -r AWSAdministratorAccess for group-based access. If the user doesn't exist yet, create it first with sso create-user.)

The CLI does not generate AWS CLI profiles — write them yourself. Append to ~/.aws/config (never overwrite existing sections; skip blocks that already exist):

[sso-session <prefix>]
sso_start_url = <start-url>
sso_region = <region>
sso_registration_scopes = sso:account:access

[profile <prefix>-dev]
sso_session = <prefix>
sso_account_id = <dev-account-id>
sso_role_name = AWSAdministratorAccess
region = <region>

<start-url> is the full Identity Center start URL collected in Step 2 — paste it verbatim, never rebuild it from a domain fragment. One [profile <prefix>-<env>] block per environment — this exact naming is what scripts/pre-deployment-checklist.sh and the db-connect scripts resolve. Then authenticate and verify every profile maps to the expected account:

aws sso login --sso-session <prefix>
for env in dev staging production shared; do
  aws sts get-caller-identity --profile <prefix>-$env --query Account --output text
done

Step 6 — CDK bootstrap with pipeline trust

Bootstrap the shared (pipeline) account first, then each stage account with trust back to shared. Honor the project's CDK_BOOTSTRAP_QUALIFIER and CDK_BOOTSTRAP_EXECUTION_POLICY_ARN env vars rather than hardcoding their defaults (config/env.ts defaults: hnb659fds / arn:aws:iam::aws:policy/AdministratorAccess):

qualifier="${CDK_BOOTSTRAP_QUALIFIER:-hnb659fds}"
exec_policy="${CDK_BOOTSTRAP_EXECUTION_POLICY_ARN:-arn:aws:iam::aws:policy/AdministratorAccess}"

npx cdk bootstrap aws://<shared-id>/<region> --profile <prefix>-shared \
  --qualifier "$qualifier"

for env in dev staging production; do
  npx cdk bootstrap aws://<env-id>/<region> --profile <prefix>-$env \
    --qualifier "$qualifier" \
    --trust <shared-id> \
    --cloudformation-execution-policies "$exec_policy"
done

The --trust flag is the manual chicken-and-egg step the project's trust-policy-stack documents as CfnOutputs — this skill is where it actually runs.

Step 7 — Wire the project

1. config/environments.ts (when the project has it): replace each environment's accountId: "PLACEHOLDER" with the real 12-digit ID from the Step 4 map, and confirm region matches. This single edit is what flips each environment from synth-only to deployable. If the project uses a different layout, skip with a note — the .lisa.config.json record below still applies.
2. GitHub secrets — only when .github/workflows/ci.yml references them:

   gh secret set AWS_ACCOUNT_ID_DEV --body "<dev-id>"
   gh secret set AWS_ACCOUNT_ID_STAGING --body "<staging-id>"
   gh secret set AWS_ACCOUNT_ID_PRODUCTION --body "<production-id>"
   gh secret set AWS_INFRA_ACCOUNT_ID --body "<shared-id>"
   

3. .lisa.config.json — record the machine-readable account map (merge with jq, preserving every other key):

   {
     "aws": {
       "region": "<region>",
       "profilePrefix": "<prefix>",
       "accounts": {
         "dev": "<dev-id>",
         "staging": "<staging-id>",
         "production": "<production-id>",
         "shared" 
       
     
   
   

Step 8 — Verify and report

• Every <prefix>-<env> profile authenticates to its expected account ID (aws sts get-caller-identity).
• scripts/pre-deployment-checklist.sh passes when the project ships it.
• npx cdk synth succeeds and no environment is skipped as non-deployable.
• Report a table: environment → account ID → profile → bootstrapped (yes/no).
• Name what remains manual, in operator-readable language — e.g. the GitHub CodeConnections handshake for pipeline mode (config/github.ts codeConnectionArn) is an interactive console step outside this skill's scope, and hardening extras (root remove-access, scp deny-iam-users, scp alert-management) are offered but require explicit confirmation since they are org-wide and destructive.

Cross-agent invocation

The same SKILL.md ships to every supported runtime via the plugin build; all logic lives here, never in the command shim.

• Claude Code / OpenCode / Cursor: /lisa-cdk:setup:aws command, or invoke the skill directly.
• Codex (no slash commands): $setup-aws-accounts (the command shim also installs as $lisa-setup-aws).
• agy / Copilot: the skill is delivered through the generated plugin variants; invoke it by name.

Rules

• Never automate the console-only steps (root MFA, enabling Identity Center, landing zone creation). Present the checklist, stop, and let a human do them. Every blocked reason must be readable by a non-technical operator.
• Always --dry-run (or status) first and show the plan before mutating an organization. root and scp subcommands are destructive org-wide — never run them without explicit user confirmation in this session.
• Check before create: list-accounts before provision-account; read ~/.aws/config before appending profile blocks; never clobber existing profiles or config keys.
• Harvest account IDs from aws organizations list-accounts, not from scraped CLI text.
• Never write credentials or secrets into the repository. Account IDs are not secret and belong in config; keys and tokens never do.
• Do not stage or modify unrelated working-tree files; the only repo edits are config/environments.ts and .lisa.config.json.
