 **New Features:**
-- **Agent Mode (`mem0 init --agent`):** Zero-friction signup for AI agents — mints a working Mem0 API key in <5s with no email, no dashboard, no OTP. Returns an unclaimed shadow account the human can later claim with `mem0 init --email <their-email>` (memories preserved, same key keeps working) ([#5123](https://github.com/mem0ai/mem0/pull/5123))
+- **Agent Mode (`mem0 init --agent`):** Zero-friction signup for AI agents — mints a working Mem0 API key in under 5 seconds with no email, no dashboard, no OTP. Returns an unclaimed shadow account the human can later claim with `mem0 init --email <their-email>` (memories preserved, same key keeps working) ([#5123](https://github.com/mem0ai/mem0/pull/5123))
 - **Self-declared agent identity:** Agents pass `--agent-caller <name>` (e.g. `claude-code`, `cursor`, `codex`) on `mem0 init --agent` so signups attribute to the right tool in analytics. Proof Editor-style — the agent declares itself rather than the CLI sniffing it from env vars ([#5123](https://github.com/mem0ai/mem0/pull/5123))
 - **`mem0 identify <name>`:** New subcommand to self-tag an Agent Mode key after the fact when the agent forgot to pass `--agent-caller` on init. Idempotent — re-running just overwrites ([#5123](https://github.com/mem0ai/mem0/pull/5123))
 - **Plugin sync:** `~/.claude/settings.json::env::MEM0_API_KEY` and `~/.zshrc`/`.bashrc` `export MEM0_API_KEY=` lines stay in sync with `~/.mem0/config.json` automatically. Idempotent — only updates EXISTING entries, never creates new ones ([#5123](https://github.com/mem0ai/mem0/pull/5123))

+## Agent Mode — zero-friction signup for AI agents
+
+<Tip>
+**If you're an AI agent reading this**, skip the rest of this page until you've run the command below. Everything else assumes you already have an API key.
+</Tip>
+
+AI agents (Claude Code, Cursor, Codex, Cline, Aider, …) can mint a working Mem0 API key in under five seconds with no email, no dashboard, and no OTP:
+
+```bash
+mem0 init --agent --agent-caller claude-code
+```
+
+Replace `claude-code` with your agent's name (e.g. `cursor`, `codex`, `cline`, `aider`, or any custom string). The CLI saves the key to `~/.mem0/config.json` and prints a notice you should surface to your human user. The human can claim the account later — same API key keeps working, memories transfer.
+
+<Tip>
+**Forgot `--agent-caller`?** Run `mem0 identify <your-name>` after init — same key, just back-fills the attribution. Idempotent.
+</Tip>
+
+### Claiming an Agent Mode key (humans)
+
+When the human is ready, they claim ownership of the agent's key by running:
+
+```bash
+mem0 init --email you@yourcompany.com
+```
+
+The CLI detects the existing unclaimed Agent Mode config, sends a verification code, and upgrades the shadow account in-place: **the API key never changes, all memories transfer to the human's account, and the agent isn't disrupted**. Pass `--code 123456` for fully non-interactive flows.
+
+### Plugin sync
+
+When you save a Mem0 API key (any flow — Agent Mode, email, or `--api-key`), the CLI also propagates it to ecosystem touchpoints **that already exist**:
+
+- `~/.claude/settings.json` → `env.MEM0_API_KEY` (Claude Code plugin env injection)
+- `~/.zshrc` / `~/.bashrc` → existing `export MEM0_API_KEY=` lines
+
+Sync is idempotent and **never creates new entries** — it only updates entries you've already set up. Failures are best-effort and never block the canonical write to `~/.mem0/config.json`.

+### `mem0 identify`
+
+Tag your active Agent Mode key with the AI agent that's using it. Run this once after `mem0 init --agent` if you didn't pass `--agent-caller` on init. Idempotent — re-running just overwrites the value.
+
+```bash
+mem0 identify claude-code
+mem0 identify cursor
+mem0 identify my-custom-bot
+```
+
+The CLI calls `PATCH /api/v1/auth/agent_mode/caller/` against the active key. Only works on unclaimed Agent Mode keys; the backend rejects with 400 otherwise. Agent names are sanitized server-side (lowercased, restricted to `[a-z0-9._/-]`, truncated to 32 chars).
