A deployment setup for a new web app using AWS infrastructure. AWS is Amazon's cloud platform; the setup can host files, deliver them through a CDN, and deploy updates from GitHub.

Creating the app's CDK infrastructure directory, bootstrapping an AWS account, and making the first deployment with S3, CloudFront, Route 53, CodePipeline, and optional services.

It provides the cloud resources and delivery pipeline needed to publish an app, including optional domains, user accounts, APIs, and model-backed functions.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00044	$0.02046
Opus 5.5	$0.00018	$0.00818
Sonnet 5.5	$0.00009	$0.00409
Haiku 4.5	$0.00004	$0.00205

Security

Grade A, and why

cdk-stack scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 131 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/app-kit:cdk-stack — render and deploy infra

This mirrors daily-deutsch/cdk/: S3 (private, OAC) → CloudFront (apex + www, ACM, www-to-apex redirect, SPA error rewrite) → Route 53 alias records → CodeStar GitHub connection → CodeBuild test + CodeBuild build/deploy → CodePipeline V2 with Source/Test/BuildAndDeploy stages.

Inputs

From the orchestrator: app_name, aws_account_id, github_owner (defaults to github.org from config), github_branch (defaults main), domain (string OR null), and three independent toggles:

needs_cognito (bool) — adds Cognito UserPool + UserPoolClient
needs_api (bool) — adds HTTP API Gateway + JWT authorizer + sample protected Lambda. Requires needs_cognito=true; refuse otherwise.
needs_llm_lambda (bool) — adds the daily-deutsch-style unauth'd Bedrock Lambda Function URL

If domain is null the app is served from the CloudFront default URL only (no Route 53, no ACM cert, no www→apex redirect).

Steps

1. Copy the template

Pick templates/vite/cdk/ or templates/nextjs/cdk/ based on the user's stack choice. Copy into <app-path>/cdk/. Rename lib/stack.ts to lib/<app-name>-stack.ts (the import in bin/app.ts expects this). Then walk the tree and replace placeholders:

Placeholder	Replacement
`{{APP_NAME}}`	kebab-case (`daily-deutsch`)
`{{APP_NAME_PASCAL}}`	PascalCase (`DailyDeutsch`)
`{{DOMAIN}}`	apex (`daily-deutsch.com`)
`{{AWS_ACCOUNT_ID}}`	child account ID
`{{GITHUB_OWNER}}`	`github.org` from config unless overridden
`{{GITHUB_BRANCH}}`	usually `main`

Strip the blocks the user didn't pick. The template has these block-pair markers in lib/<app-name>-stack.ts and bin/app.ts. Block-pair stripping = delete everything from the // BEGIN_X line through the matching // END_X line, inclusive.

Condition	Markers to keep	Markers to strip
`domain` is a string	`BEGIN_DOMAIN` / `END_DOMAIN`	`BEGIN_NO_DOMAIN` / `END_NO_DOMAIN`
`domain` is null	`BEGIN_NO_DOMAIN` / `END_NO_DOMAIN`	`BEGIN_DOMAIN` / `END_DOMAIN`
`needs_llm_lambda=false`	—	`BEGIN_LLM_LAMBDA` / `END_LLM_LAMBDA` (all occurrences). Also delete `lambda/llm/` directory.
`needs_cognito=false`	—	`BEGIN_COGNITO` / `END_COGNITO` (all occurrences).
`needs_api=false`	—	`BEGIN_API` / `END_API` (all occurrences). Also delete `lambda/hello-protected/` directory.

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

cdk-stack is a skill published in the GitHub repository jpd44/mesh44-plugins (2 stars, last pushed 2mo ago), licensed MIT. It adds 44 tokens to every session and 2,046 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
