craft-flags keeps one per-user file, ArtCraft/flags.toml beside the AI layer's ArtCraft/ai, that the launcher and every app read; CRAFT_FLAGS overrides it for one run. Every flag is off by default. The first two: AI-MCP (AI agents through MCP) and AI-MODELS (AI models and services). Loading never fails: a missing or damaged file means defaults, with the reason in Flags::problems. set() changes one flag atomically and keeps everything else in the file, and never overwrites a file it can't read. In the browser every flag is at its default. Closes #1118 --------- Co-authored-by: David Mann <daaavid.mann@gmail.com>

# Craft Flags
|
|
|
|
`craft-flags` lets a feature ship in every Craft app and the ArtCraft Launcher while it stays off
|
|
until a person turns it on. Every flag is off by default.
|
|
|
|
- **One file for the suite:** `ArtCraft/flags.toml` in the per-user local configuration folder
|
|
(`%LOCALAPPDATA%` on Windows, `~/Library/Application Support` on macOS, `$XDG_CONFIG_HOME` on
|
|
Linux), beside the AI layer's `ArtCraft/ai`. `CRAFT_FLAGS_FILE` names another file.
|
|
- **One run:** `CRAFT_FLAGS=AI-MCP,-AI-MODELS` overrides the file.
|
|
- **Never crashes:** a missing or damaged file means every flag is at its default, with the
|
|
reason in `Flags::problems`. `set` changes one flag atomically and keeps everything else in the
|
|
file; it refuses to touch a file it cannot read.
|
|
- **Browser:** no file, no environment: every flag is at its default.
|
|

## Flags
|
|
|
|
| Constant | Id | What it gates |
|
|
|---|---|---|
|
|
| `AI_MCP` | `AI-MCP` | AI agents using the Craft apps through MCP: the launcher's AI agents settings, the `craft-ai-mcp` gateway, the apps' agent connection settings |
|
|
| `AI_MODELS` | `AI-MODELS` | Choosing AI models and services for AI tools such as Generative Fill |
|
|
|
|
A new flag is a new constant here and a row in `ALL`, so the launcher can list it and every app
|
|
names it the same way.
|
|
|
|
## Use
|
|
|
|
```rust
|
|
let flags = craft_flags::load();
|
|
if flags.enabled(&craft_flags::AI_MCP) {
|
|
// show the agent connection settings
|
|
}
|
|
```
|
|
|
|
The launcher turns a flag on with `craft_flags::set(&path, craft_flags::AI_MCP.id, true)`, where
|
|
`path` is `craft_flags::default_path()`. Apps read the flags when they start; a flag changed
|
|
while an app runs takes effect at its next start, unless the app loads them again.
