+# Business Analyst bundle
+
+A role bundle for business analysts working in a Spec-Driven Development flow:
+requirements elicitation, traceability, and acceptance criteria.
+
+## What it installs
+
+- **Extension** `agent-context` — keeps the agent context file in sync.
+- **Preset** `requirements-elicitation` (priority 10, append) — elicitation and
+  analysis command set.
+- **Steps** `capture-requirements`, `trace-acceptance-criteria`.
+- **Workflow** `requirements-to-spec` — turns captured requirements into a spec.
+
+This bundle is **integration-agnostic**: it inherits the project's active
+integration.
+
+## Usage
+
+```bash
+specify bundle validate --path examples/bundles/business-analyst
+specify bundle build --path examples/bundles/business-analyst --output dist/
+```
