+### agents-init
+
+    Synopsis:  agents-init [--agents | --plugins]
+    Scaffold an AGENTS/ sub-repository for tracking agent specs and plugin
+    directories. Creates AGENTS/ as a standalone git repo, initializes
+    standard plugin subdirectories (superpowers/, plans/, specs/), moves any
+    existing AGENTS.md and docs/plugin dirs into the sub-repo, and replaces
+    them with relative symlinks. Also adds CLAUDE.md -> AGENTS/AGENTS.md so
+    Claude Code picks up the shared agent instructions. Adds all managed
+    paths to .gitignore and auto-commits every change inside the AGENTS/
+    sub-repo. Fully idempotent: a second run produces no output and no new
+    commits. Flags: --agents re-runs only the AGENTS.md / symlink step;
+    --plugins re-runs only the plugin-directory wiring step. Called
+    automatically by the claude wrapper on every invocation.

     Synopsis:  claude [args...]
-    Wrapper for the claude CLI. Before launching, checks the current
-    directory and the git project root for CLAUDE.md; when it is absent but
-    AGENTS.md is present, creates a relative symlink CLAUDE.md -> AGENTS.md
-    so Claude Code picks up shared agent instructions without duplicating
-    the file. All arguments are forwarded verbatim. Command shadow (C1):

     passed through to the real claude binary unchanged.
