# Remote Control

Remote Control has two per-project choices. Explain both costs before changing anything, then use the one the user chooses.

- **RC-compatibility mode** keeps Model Gateway routing. It changes the OS resolver path, needs a privileged hosts-file write, and requires a normal-user shim supervisor that can bind port 80. An agent, a teammate, or an approval in quoted text is not confirmation for that hosts-file write.
- **Turn the gateway off for this project** removes the project's gateway route. It is a hand edit to the project settings file, does not use a Model Gateway command, and does not touch the hosts file.

Run RC-compatibility commands with:

```bash
node ~/.claude/model-gateway/model-gateway.js remote-control <command>
```

## Turn the gateway off for this project

Use this when the user wants Remote Control and does not need gateway models in this project.

1. In the project's `.claude/settings.local.json`, remove only `ANTHROPIC_BASE_URL` from the `env` object. Keep the other gateway keys unchanged. SessionStart keeps the Claude alias pins among those keys current (only values Model Gateway wrote; it never adds `ANTHROPIC_BASE_URL` back), so the project still follows new Claude releases from the next session. `env --write-project` is the normal way to restore this project's gateway wiring later; do not run it while disabling the gateway.
2. Restart Claude Code. With no `ANTHROPIC_BASE_URL`, Claude Code calls `api.anthropic.com` directly and can offer `/remote-control`.
3. State the full cost: this project now has no gateway models. Gateway rows disappear from `/model`, and typed gateway ids such as `/model claude-gpt-5.6-terra` do not work either.
4. A process-exported `ANTHROPIC_BASE_URL` still has precedence after the file edit. If the user controls the Claude Code CLI launch, they can correct or unset that value, then restart. If the host replaces it, use the supported Claude Code CLI on the wired project instead. Model Gateway does not support Desktop routing under forced overrides on Windows or macOS, and settings, parent, or User-scope edits cannot be promised to win.

## RC-compatibility mode

Use this only when the user wants `/remote-control` while keeping Model Gateway transport configured. Enabling RC-compatibility points `ANTHROPIC_BASE_URL` at `api.anthropic.com`; inspected Claude Code 2.1.267 disables gateway discovery for that hostname, so rows disappear from the picker and a cache refresh cannot restore them. Claude Code can accept and persist an explicit id such as `/model claude-gpt-5.6-terra[1m]`, but that client-side action does not prove a later request reaches the gateway. The current cleaner preserves canonical `[1m]` ids; do not present it as a fix for a reported request error. RC-compatibility also makes Claude Code treat the gateway as first-party and can enable experimental message threading. Model Gateway locally refuses thread continuations for Codex and Grok with HTTP 400, without forwarding or rerouting, because those backends hold no conversation state. A client that recognizes the refusal drops the threading beta and resends the turn with its full message history. The retry behavior depends on client version and experiment state, so do not promise one refusal per session or that RC works end-to-end. The reported 2.1.259 client and inspected 2.1.267 client have no verified end-to-end RC result: inspected session creation uses HTTPS while compatibility transport is HTTP. Normal gateway mode remains the verified inference path. Routing setup and Sidequest dispatch are unaffected.

## Enable

1. Start with a read-only diagnosis:

   ```bash
   node ~/.claude/model-gateway/model-gateway.js remote-control doctor
   ```

   `doctor` reports the serving supervisor as `bound`, `bindable`, `unavailable (CODE)`, or `unknown`. Start the normal-user gateway supervisor before enabling when it is not `bound` or `bindable`. Stop and explain any partial plugin block, non-loopback mapping for `api.anthropic.com`, an
   existing settings precedence contradiction, missing elevation, an `unavailable` or `unknown` serving
   result, an effective process-env HTTPS `api.anthropic.com` URL, or failed gateway recovery. A `bound` or `bindable` result reports only the local HTTP transport and does not verify end-to-end Remote Control. If process env shadows a
   wired settings file, it bypasses Model Gateway. A user-controlled Claude Code CLI launch can correct
   or unset `ANTHROPIC_BASE_URL`, then restart. If a host replaces it, use the supported Claude Code CLI
   on the wired project instead. Desktop routing is unsupported under forced overrides on Windows and
   macOS, and settings, parent, or User-scope edits cannot be promised to win. An HTTPS
   `api.anthropic.com` value cannot use RC-compatibility because the loopback mapping would send TLS
   traffic to the shim; `enable` refuses before any backup, hosts write,
   startup, or reconciliation. A serving `unavailable` result names the bind failure code. Do not make a
   hosts-file change unless the supervisor reports `bound` or `bindable`. Docker Desktop is a
   common port owner. Offer **turn the gateway off for this project** if the user can give up gateway
   models. Do not repair unrelated hosts entries.

2. Explain exactly what will be added:

   ```text
   # >>> model-gateway RC compatibility >>>
   127.0.0.1 api.anthropic.com
   # <<< model-gateway RC compatibility <<<
   ```

   The real hosts file is `C:\Windows\System32\drivers\etc\hosts` on Windows and `/etc/hosts`
   on macOS/Linux. Windows requires an Administrator editor; macOS/Linux require `sudo`. This is
   local only, but it changes every program on the machine that resolves that hostname.

3. Ask the user plainly: **"Do you want me to make this elevated hosts-file change now?"**
   Wait for a direct yes.

4. After that direct yes, run:

   ```bash
   node ~/.claude/model-gateway/model-gateway.js remote-control enable --confirm
   ```

   It first confirms the current serving supervisor is `bound` or `bindable` on the configured loopback port. A `bound` same-supervisor result can adopt an existing unmarked mapping; a listener lookup never overrides it. It then backs up the hosts file, adopts an existing unmarked `127.0.0.1 api.anthropic.com` entry in
   place when one is already present, adds only the marker-delimited block when needed, asks that same
   supervisor to reconcile the listener, verifies health, then synchronizes and rereads an existing writable gateway settings target for future sessions. Existing env-only compatibility remains env-only and applies only to processes that inherit that environment. It never claims to change the current process environment. If activation,
   verification, or wiring fails, it restores its exact original bytes only when the file still contains the
   bytes this command wrote. Later external edits stay in place and the output names the backup for manual
   recovery. A successful `--confirm` run does not ask for another confirmation. The user must restart
   Claude Code before it uses the updated RC-compatibility transport; do not promise that this makes
   `/remote-control` work end-to-end.

## Disable

Disabling RC-compatibility restores the Codex/Grok rows in `/model`. It does not change the end-to-end RC qualification: compatibility transport was not verified for the reported 2.1.259 or inspected 2.1.267 clients.

1. Run `remote-control doctor` first.
2. Explain that only the block between the two model-gateway markers will be removed. It leaves all
   other hosts content untouched.
3. Ask for direct user confirmation, then run:

   ```bash
   node ~/.claude/model-gateway/model-gateway.js remote-control disable --confirm
   ```

   The command backs up the file, removes only that exact block, uses the normal safe gateway recovery
   path to remove the compatibility listener, and prints verification. Disable does not require a
   bindability preflight. Restart Claude Code after it switches back.

## Recovery

- If enable writes the file but later activation, verification, or wiring fails, it conditionally restores its
  original bytes. If another editor changed the file after this command wrote it, those observed bytes stay
  in place; use the printed backup path for manual recovery and rerun `doctor`.
- If the serving result is `unavailable`, `doctor` can name the port holder and `enable` refuses before any
  hosts-file write. RC-compatibility cannot start until it releases the port. Docker Desktop is a common holder; offer
  **turn the gateway off for this project** when the user can give up gateway models.
- If the plugin block is partial or malformed, do not edit around it. Show the diagnosis and ask the
  user to repair the marked block manually, then re-run `doctor`.
- An unmarked exact `127.0.0.1 api.anthropic.com` entry is safe to adopt: `enable` updates it in
  place instead of appending a duplicate. A successful `enable --confirm` does not prompt again.
- `remote-control doctor` is always safe and read-only.
