-> Install-name clarification: older posts may still show `ecc@ecc`. That shorthand is deprecated. Anthropic marketplace/plugin installs are keyed by a canonical plugin identifier, so ECC standardized on `everything-claude-code@everything-claude-code` to keep the listing name, install path, `/plugin list`, and repo docs aligned instead of maintaining two different public names for the same plugin.
+### Naming + Migration Note
+
+ECC now has three public identifiers, and they are not interchangeable:
+
+- GitHub source repo: `affaan-m/everything-claude-code`
+- Claude marketplace/plugin identifier: `everything-claude-code@everything-claude-code`
+- npm package: `ecc-universal`
+
+This is intentional. Anthropic marketplace/plugin installs are keyed by a canonical plugin identifier, so ECC standardized on `everything-claude-code@everything-claude-code` to keep the listing name, `/plugin install`, `/plugin list`, and repo docs aligned to one public install surface. Older posts may still show the old short-form nickname; that shorthand is deprecated. Separately, the npm package stayed on `ecc-universal`, so npm installs and marketplace installs intentionally use different names.
