Family sync

The rule

The five templates share everything except the Presentation layer. A shared change is made and reviewed in CleanMinimalApi first, then the same branch is opened in the other four with the same title, in this order: MCP, GraphQL, Web API, Lambda Function.

Steps

1. Merge-ready in CleanMinimalApi first.

2. For each other template, on the same branch name, copy the shared folders over and swap the name (no rsync needed):

   SRC=../CleanMinimalApi; NAME=CleanWebApi
   for d in src/Application src/Infrastructure tests/Application.Tests.Unit tests/Infrastructure.Tests.Integration; do
     rm -rf "$d" && (cd "$SRC" && tar cf - "$d") | tar xf -
   done
   grep -rl CleanMinimalApi src/Application src/Infrastructure tests/Application.Tests.Unit tests/Infrastructure.Tests.Integration \
     | xargs sed -i "s/CleanMinimalApi/$NAME/g"

3. Copy the shared skills and the persona the same way, then edit the Presentation rows of AGENTS.md by hand. A new repository or maintainer skill also goes in the RepositorySkills list in template/template.csproj, so it stays out of the package. A presentation skill with the same name in every template (expose-a-use-case, json-serialization, presentation-integration-tests) is written for each template's own code, never copied.
4. Prove they match with the commands under Check. There should be no differences.
5. Build and test every template. Open the pull requests with the same title and description.

Don't

• Change a shared file in one template only.
• Merge the copies before the CleanMinimalApi pull request is approved.
• Copy bin/ or obj/ folders.

Check

Run in each copy, after the build:

SRC=../CleanMinimalApi; NAME=CleanWebApi; SHARED="src/Application src/Infrastructure tests/Application.Tests.Unit tests/Infrastructure.Tests.Integration"
tmp=$(mktemp -d); tar cf - --exclude=bin --exclude=obj $SHARED | (cd "$tmp" && tar xf -)
grep -rl "$NAME" "$tmp" | xargs sed -i "s/$NAME/CleanMinimalApi/g"
for d in $SHARED; do diff -r --exclude=bin --exclude=obj "$SRC/$d" "$tmp/$d"; done   # expect no output
dotnet build && dotnet test
