+## Work + Amplifier development
+
+Use the independent Work-based development root:
+
+```text
+git+https://github.com/microsoft/amplifier-bundle-work@main#subdirectory=bundles/work-amp-dev.md
+```
+
+Its exact includes are:
+
+```yaml
+includes:
+  - bundle: work:bundle.md
+  - bundle: git+https://github.com/microsoft/amplifier-foundation@main#subdirectory=behaviors/amp-dev.yaml
+```
+
+This is **Work + the portable amp-dev capability**, not Anchors + Work.
+It includes neither Anchors nor `presets/anchors-work.md`. Work retains its
+`loop-live` and `context-managed` defaults. Foundation's behavior adds the lean
+`amp-dev:amplifier-dev-expert`, short ecosystem instructions, and the Tester
+behavior with DTU/Gitea capabilities; it selects no orchestrator or context
+manager. Applications may override the complete root's runtime defaults.
+
+Both Work roots explicitly load `@work:context/system.md`, the unchanged
+operating instruction shared at that path. Root bodies replace included bodies,
+so the variant preserves Work's instruction rather than relying on include
+fallback. The amp-dev context accumulates through its behavior and is not
+repeated in either body.
+
+Work is included first. List-valued tool configuration accumulates parent-first,
+so Work skill sources precede sources contributed by the amp-dev dependency
+chain; reversing the includes is not a byte-identical composition. Verify the
+intended same-name skill precedence. Local composition and prompt-construction
+qualification passes; an isolated host also passed authenticated HTTPS, real
+root/expert execution and browser conversation reload checks.
+See [execution validation](docs/EXECUTION-VALIDATION.md).
