feat: v2.1.0 — faster fallback with first-byte timeout and reduced defaults

- Default timeout: 300s → 120s (CLAUDE_TIMEOUT)
- New: first-byte timeout at 30s (CLAUDE_FIRST_BYTE_TIMEOUT) — aborts early
  if Claude CLI produces no stdout, triggering faster fallback
- Pool disabled by default (POOL_SIZE=0) — on-demand spawning is now the
  default; set CLAUDE_POOL_SIZE>0 to re-enable
- Health endpoint now reports timeout and firstByteTimeout values
- Startup log shows pool mode (disabled/on-demand vs active)

 # openclaw-claude-proxy
 
-Use your Claude Pro/Max subscription as an OpenClaw model provider — no API key needed.
+> **Already paying for Claude Pro/Max? Use it as your OpenClaw model provider — $0 extra API cost.**
+
+A lightweight, zero-dependency proxy that lets [OpenClaw](https://github.com/openclaw/openclaw) agents talk to Claude through your existing subscription. One command to set up, one file to run.
+
+## v2.0.0 — Major Upgrade
+
+**What's new:**
+- **On-demand spawning** — eliminates the pool crash loops, DEGRADED states, and stdin timeout errors from v1.x. Each request spawns a fresh `claude -p` process with stdin written immediately. No more stale workers, no more backoff spirals.
+- **Session management** — multi-turn conversations use `--resume` to avoid resending full history. Reduces token waste and enables Claude Code's built-in context compression on long conversations.
+- **Full tool access** — expanded default tools (Bash, Read, Write, Edit, Glob, Grep, WebSearch, WebFetch, Agent). Configurable via `CLAUDE_ALLOWED_TOOLS` or bypass all checks with `CLAUDE_SKIP_PERMISSIONS=true`.
+- **System prompt pass-through** — set `CLAUDE_SYSTEM_PROMPT` to inject context into every request.
+- **MCP config support** — set `CLAUDE_MCP_CONFIG` to load MCP servers (Telegram, etc.) into claude -p calls.
+- **Concurrency control** — `CLAUDE_MAX_CONCURRENT` prevents runaway process spawning (default: 5).
+- **Auth health monitoring** — periodic `claude auth status` checks with status exposed on `/health`.
+- **Session API** — `GET /sessions` to list, `DELETE /sessions` to clear active sessions.
+- **Improved diagnostics** — `/health` endpoint shows stats, active sessions, recent errors, auth status, and full config.
+
+**Coexistence with Claude Code interactive mode:**
+OCP and Claude Code (interactive/Telegram) run on completely different paths and can coexist on the same machine without conflict:
+- OCP: `localhost:3456` (HTTP) → spawns `claude -p` processes (per-request, stateless)
+- CC: MCP protocol (in-process) → persistent interactive session
+- No shared ports, no shared processes, no shared sessions
+
+**Daemon advantage over CC:**
+OCP runs as a system daemon (launchd/systemd) that auto-starts on boot and auto-recovers from crashes. Unlike Claude Code interactive mode, OCP does not require a terminal session to stay open — it survives disconnects, reboots, and SSH drops. Combined with OpenClaw's memory system, this means your agents never lose continuity.

+## Session Management (v2.0)
+
+Multi-turn conversations can use sessions to avoid resending full message history on every request.
+
+**How to enable:** Include a `session_id` or `conversation_id` field in your request body, or set the `X-Session-Id` / `X-Conversation-Id` header.
+
+```json
+{
+  "model": "claude-opus-4-6",
+  "session_id": "conv-abc-123",
+  "messages": [
+    {"role": "user", "content": "Hello"},
+    {"role": "assistant", "content": "Hi there!"},
+    {"role": "user", "content": "What did I just say?"}
+  ]
+}
+```
+
+**First request** with a new session_id: all messages are sent, session is persisted via `--session-id`.
+**Subsequent requests** with the same session_id: only the latest user message is sent via `--resume`, reducing token consumption.
+
+Sessions expire after 1 hour of inactivity (configurable via `CLAUDE_SESSION_TTL`).
+
+**API endpoints:**
+- `GET /sessions` — list all active sessions
+- `DELETE /sessions` — clear all sessions
+
+## Security
+
+- **Localhost only** — the proxy binds to `127.0.0.1` and is not exposed to the internet or your local network
+- **Bearer token auth (optional)** — set `PROXY_API_KEY` to require a Bearer token on all requests (except `/health`). When unset, auth is disabled for backwards compatibility
+- **No API keys for Claude** — authentication to Anthropic goes through Claude CLI's OAuth session, no Anthropic credentials are stored in the proxy
+- **Auto-start via launchd/systemd** — `node setup.mjs` installs a user-level launch agent (macOS) or systemd user service (Linux) so the proxy starts automatically on login
+- **Remove auto-start** at any time:
+
+```bash
+node uninstall.mjs
+```

-## Auto-start on Login (macOS)
+## Authentication
+
+The proxy supports optional Bearer token authentication via the `PROXY_API_KEY` environment variable.
+
+**When `PROXY_API_KEY` is set**, all requests (except `GET /health`) must include a valid `Authorization: Bearer <token>` header. Requests with a missing or invalid token receive a `401 Unauthorized` response.
+
+**When `PROXY_API_KEY` is not set**, authentication is disabled and all requests are accepted.
 
-Add to your `~/.zshrc`:
 ```bash
-bash ~/.openclaw/projects/claude-proxy/start.sh 2>/dev/null
+# Start with auth enabled
+PROXY_API_KEY=my-secret-token node server.mjs
+```
+
+## Architecture: v1 vs v2
+
+| | v1.x (pool) | v2.0 (on-demand) |
+|---|---|---|
+| Process lifecycle | Pre-spawn idle workers | Spawn per request |
+| Crash handling | Backoff → DEGRADED → manual restart | No crash loops (no idle workers) |
+| Session support | None (stateless) | --resume with session tracking |
+| Tool access | 6 tools hardcoded | Configurable, expanded defaults |
+| System prompt | None | CLAUDE_SYSTEM_PROMPT env |
+| MCP support | None | CLAUDE_MCP_CONFIG env |
+| Concurrency | Unlimited (dangerous) | CLAUDE_MAX_CONCURRENT limit |
+| Auth monitoring | None | Periodic health checks |
+| Diagnostics | Basic /health | Full stats, sessions, errors |
+
+## Coexistence with Claude Code
+
+OCP and Claude Code interactive mode (including Telegram bots) are completely independent:
+
+| | OCP (this proxy) | CC interactive |
+|---|---|---|
+| Protocol | HTTP (localhost:3456) | MCP (in-process) |
+| Process model | Per-request spawn | Persistent session |
+| Lifecycle | Daemon (auto-start, auto-recover) | Requires terminal |
+| Permission model | Pre-approved tools | Interactive prompts |
+| Use case | Automated agent work | Human-in-the-loop |
+
+Both can run on the same machine simultaneously. No shared state, no port conflicts.
+
+## Recovery after OpenClaw upgrade
+
+OpenClaw upgrades (`npm update -g openclaw`) **do not overwrite** the user config at `~/.openclaw/openclaw.json`. However, if the claude-local models stop working after an upgrade:
+
+### One-command recovery
+
+```bash
+cd ~/.openclaw/projects/claude-proxy   # or wherever you cloned it
+git pull                                # pull latest version
+node setup.mjs                          # reconfigure OpenClaw + start proxy
+openclaw gateway restart
 ```
 
 ## Notes
 
 - Cost shows as $0 because billing goes through your Claude subscription
-- The `🔑` field in `/status` may show the dummy auth key — this is normal
-- Each request spawns a `claude -p` process; concurrent requests are supported
+- Each request spawns a `claude -p` process; concurrent requests are capped by `CLAUDE_MAX_CONCURRENT`
 - The proxy must run on the same machine as the Claude CLI (uses local OAuth)
+- Session data is stored by Claude CLI on disk; session map is in-memory (lost on proxy restart)

 /**
- * openclaw-claude-proxy — OpenAI-compatible proxy for Claude CLI
+ * openclaw-claude-proxy v2.0.0 — OpenAI-compatible proxy for Claude CLI
  *
  * Translates OpenAI chat/completions requests into `claude -p` CLI calls,
  * letting you use your Claude Pro/Max subscription as an OpenClaw model provider.
  *
- * Supports both streaming (SSE) and non-streaming responses.
+ * v2.0.0 highlights:
+ *   - On-demand spawning: eliminates pool crash loops from v1.x
+ *   - Session management: --resume support reduces token waste on multi-turn
+ *   - Full tool access: configurable allowedTools (expanded defaults)
+ *   - System prompt & MCP config pass-through
+ *   - Concurrency control with queuing
+ *   - Coexists safely with Claude Code interactive mode (Telegram, IDE, etc.)
  *
  * Env vars:
  *   CLAUDE_PROXY_PORT        — listen port (default: 3456)
- *   CLAUDE_BIN         — path to claude binary (default: "claude")
+ *   CLAUDE_BIN               — path to claude binary (default: auto-detect)
+ *   CLAUDE_TIMEOUT           — per-request timeout in ms (default: 300000)
+ *   CLAUDE_ALLOWED_TOOLS     — comma-separated tools to allow (default: expanded set)
+ *   CLAUDE_SKIP_PERMISSIONS  — "true" to bypass all permission checks (default: false)
+ *   CLAUDE_SYSTEM_PROMPT     — system prompt appended to all requests
+ *   CLAUDE_MCP_CONFIG        — path to MCP server config JSON file
+ *   CLAUDE_SESSION_TTL       — session TTL in ms (default: 3600000 = 1h)
+ *   CLAUDE_MAX_CONCURRENT    — max concurrent claude processes (default: 5)
+ *   PROXY_API_KEY            — Bearer token for API auth (optional)
