+# ECHO Memory Codex Plugin
+
+Codex-native version of the ECHO memory plugin. It exposes one skill, `echo-memory`, with the vault contract, routing map, scaffold, and Python operational scripts needed to read, write, bootstrap, migrate, and health-check Jason's ECHO Obsidian vault.
+
+## Runtime
+
+Set `ECHO_KEY` before making live vault calls. The plugin does not ship a bearer token.
+
+Optional:
+
+- `ECHO_BASE`, default `https://echoapi.alwisp.com`
+- `ECHO_TODAY`, for deterministic date handling
+- `ECHO_VERIFY`, default `1`
+- `ECHO_LOCK_TTL`, default `900`
+
+Primary scripts live in `skills/echo-memory/scripts/`:
+
+- `echo.py`
+- `bootstrap.py`
+- `migrate.py`
+- `vault_lint.py`
+- `routing.json`
+
