+### Qoder CLI and IDE
+
+ECC ships a native Qoder plugin that reuses the canonical 302 skills, 71 agents,
+95 legacy command shims, and the pinned `chrome-devtools` MCP definition. From a
+reviewed checkout, validate and install it with Qoder CLI:
+
+```bash
+qoder plugins validate . --strict
+qoder plugins install .
+qoder plugins list
+```
+
+For Qoder IDE, upload a ZIP of the repository root. The ZIP root must contain
+`.qoder-plugin/` together with `skills/`, `agents/`, `commands/`, `hooks/`,
+`scripts/`, and `.mcp.json`; uploading only the manifest directory or one
+`SKILL.md` omits required resources.
+
+The universal Node.js 18+ requirement applies to Qoder's non-interactive hook
+environment. The MCP server also requires `npx` and network access on first use.
+Qoder receives one reviewed, cross-platform `SessionStart` bootstrap using
+`QODER_PLUGIN_ROOT` and exec-form arguments. ECC does not copy the full Claude
+hook profile into Qoder: blocking tool hooks, async stop jobs, and
+Claude-specific matchers remain outside this initial native integration. See
+the [.qoder-plugin notes](.qoder-plugin/README.md) for the exact boundary.
