/feature-impl — implement one sprint item end-to-end

Prerequisites

An Implementation Brief (produced by the feature-prep subagent) must be in the current conversation context. If one is not present, invoke it now:

Agent({
  subagent_type: "feature-prep",
  description: "Prepare implementation brief",
  prompt: "Sprint: [version]\nItem: [label] — [title]\n\n[full roadmap item text]"
})

Then continue once the brief is returned.

Step 1 — State the item

Before touching any file, state clearly which item you are implementing (e.g. "Implementing v2.4.0.0 A1 — Clear the search field after classify"). This anchors the conversation.

Step 2 — Implement

Work through each file in the brief's "Files to modify" and "Files to create" sections. Read the current file content (or the relevant section) before editing. Apply exactly the changes described in "Required changes" — no opportunistic refactoring of surrounding code.

Follow CLAUDE.md coding rules throughout: no comments unless the WHY is non-obvious, no extra abstractions, no error handling for impossible cases.

Step 3 — Localization

For every key listed in the brief's "Localization" section:

• Add the key + English value to src/RBLclass.AddIn/Resources/Strings.resx.
• Add translated values to Strings.fr.resx and Strings.de.resx.

ResourceParityTests fails the build if any key is missing or has mismatched {n} placeholders — never skip this step.

Step 4 — xUnit tests

For every test case in the brief's "xUnit tests" section:

• Add it to the specified test class in tests/RBLclass.Core.Tests/.
• Run dotnet test tests/RBLclass.Core.Tests/ --verbosity minimal and confirm all tests pass before proceeding.

Step 5 — Build check

msbuild is not on PATH on this machine — resolve it via vswhere first (same lookup Reload-Addin.ps1 uses), then build to catch compilation errors before reloading into Outlook:

$vswhere = "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe"
$msbuild = & $vswhere -latest -prerelease -products * -requires Microsoft.Component.MSBuild -find "MSBuild\**\Bin\MSBuild.exe" | Select-Object -First 1
if (-not $msbuild -or -not (Test-Path $msbuild)) { throw "MSBuild not found via vswhere." }
& $msbuild "src\RBLclass.AddIn\RBLclass.AddIn.csproj" /p:Configuration=Debug "/p:Platform=Any CPU" /t:Build /v:minimal /nologo
