# CyberM.debug — client runtime

Runs inside the game process. Reads and presentation are local; anything that changes shared state has to go through the server.

3 functions.

## command

```lua
CyberM.debug.command(commandLine)
```

`GAME` — Requires a live game instance.

Runs one registered native laboratory command directly.

Requires `debug.runtime` and the trusted `cyberm_debug` owner. Input is limited to 4096 bytes and unknown commands are not forwarded to the server.

| Parameter | Type | Required | Default |
|---|---|---|---|
| `commandLine` | `string` | required | — |

Returns: `true and command result on success`, `false and reason`

Registered in `ResourceHost.cpp` (line 6551) as `LuaDebugCommand`.

## eval

```lua
CyberM.debug.eval(source, [label])
```

`GAME` — Requires a live game instance.

Compiles and executes a bounded text-only Lua chunk in the privileged debug VM.

Requires `debug.runtime` and the trusted `cyberm_debug` owner. Source is limited to 32 KiB, the optional chunk label to 64 bytes, returned values to 16 and result text to 8 KiB. The ordinary memory, instruction and frame-time quotas remain active.

| Parameter | Type | Required | Default |
|---|---|---|---|
| `source` | `string` | required | — |
| `label` | `string` | optional | `exec` |

Returns: `true and bounded result text on success`, `false and compile/runtime reason`

## redscript

```lua
CyberM.debug.redscript(command)
```

`GAME` — Requires a live game instance.

Queues one bounded command through the REDscript debug bridge.

Requires `debug.runtime` and the trusted `cyberm_debug` owner. The opaque command is limited to 4096 bytes and executes from a genuine REDscript frame.

| Parameter | Type | Required | Default |
|---|---|---|---|
| `command` | `string` | required | — |

Returns: `true and bridge result on success`, `false and reason`
