+# Migration to pnpm
+
+This project has been migrated from npm to pnpm to improve dependency management and developer experience.
+
+## Why pnpm?
+
+- **Faster installation**: pnpm is significantly faster than npm and yarn
+- **Disk space savings**: pnpm uses a content-addressable store to avoid duplication
+- **Phantom dependency prevention**: pnpm creates a strict node_modules structure
+- **Native workspaces support**: simplified monorepo management
+
+## How to use pnpm
+
+### Installation
+
+```bash
+# Global installation of pnpm
+npm install -g pnpm@10.8.1
+
+# Or with corepack (available with Node.js 22+)
+corepack enable
+corepack prepare pnpm@10.8.1 --activate
+```
+
+### Common commands
+
+| npm command     | pnpm equivalent  |
+| --------------- | ---------------- |
+| `npm install`   | `pnpm install`   |
+| `npm run build` | `pnpm run build` |
+| `npm test`      | `pnpm test`      |
+| `npm run lint`  | `pnpm run lint`  |
+

+## Configuration files
+
+- **pnpm-workspace.yaml**: Defines the packages included in the monorepo
+- **.npmrc**: Configures pnpm behavior
+- **Root package.json**: Contains shared scripts and dependencies
+
+## CI/CD
+
+CI/CD workflows have been updated to use pnpm instead of npm. Make sure your CI environments use pnpm 10.8.1 or higher.
+
+## Known issues
+
+If you encounter issues with pnpm, try the following solutions:
+
+1. Remove the `node_modules` folder and `pnpm-lock.yaml` file, then run `pnpm install`
+2. Make sure you're using pnpm 10.8.1 or higher
+3. Verify that Node.js 22 or higher is installed

 - `thread/fork` — fork an existing thread into a new thread id by copying the stored history; emits `thread/started` and auto-subscribes you to turn/item events for the new thread.
 - `thread/list` — page through stored rollouts; supports cursor-based pagination and optional `modelProviders` filtering.
 - `thread/loaded/list` — list the thread ids currently loaded in memory.
-- `thread/read` — read a stored thread by id without resuming it; optionally include turns via `includeTurns`.
 - `thread/archive` — move a thread’s rollout file into the archived directory; returns `{}` on success.
-- `thread/name/set` — set or update a thread’s user-facing name; returns `{}` on success. Thread names are not required to be unique; name lookups resolve to the most recently updated thread.
-- `thread/unarchive` — move an archived rollout file back into the sessions directory; returns the restored `thread` on success.
 - `thread/rollback` — drop the last N turns from the agent’s in-memory context and persist a rollback marker in the rollout so future resumes see the pruned history; returns the updated `thread` (with `turns` populated) on success.
 - `turn/start` — add user input to a thread and begin Codex generation; responds with the initial `turn` object and streams `turn/started`, `item/*`, and `turn/completed` notifications.

 ## Auth endpoints
 
 The JSON-RPC auth/account surface exposes request/response methods plus server-initiated notifications (no `id`). Use these to determine auth state, start or cancel logins, logout, and inspect ChatGPT rate limits.
 
-### Authentication modes
-
-Codex supports these authentication modes. The current mode is surfaced in `account/updated` (`authMode`) and can be inferred from `account/read`.
-
-- **API key (`apiKey`)**: Caller supplies an OpenAI API key via `account/login/start` with `type: "apiKey"`. The API key is saved and used for API requests.
-- **ChatGPT managed (`chatgpt`)** (recommended): Codex owns the ChatGPT OAuth flow and refresh tokens. Start via `account/login/start` with `type: "chatgpt"`; Codex persists tokens to disk and refreshes them automatically.
-
 ### API Overview
 
 - `account/read` — fetch current account info; optionally refresh tokens.
-- `account/login/start` — begin login (`apiKey`, `chatgpt`).
+- `account/login/start` — begin login (`apiKey` or `chatgpt`).
 - `account/login/completed` (notify) — emitted when a login attempt finishes (success or error).
 - `account/login/cancel` — cancel a pending ChatGPT login by `loginId`.
 - `account/logout` — sign out; triggers `account/updated`.
