Configuration

Every CodeLoop knob is in a small set of files under .codeloop/ in your project root, plus a handful of environment variables. npx codeloop initseeds sensible defaults — this page documents everything you can change.

Django / Rails / Go (via plugin)

For non-built-in stacks, use .codeloop/plugins.jsonto wire your existing CLI test runner into the loop. Plugins behave exactly like first-party runners — failures count toward the gate and surface in the dashboard.

iOS (Xcode)

{
  "project_type": "xcode",
  "runners": {
    "build": { "command": "xcodebuild -scheme MyApp -destination 'platform=iOS Simulator,name=iPhone 15'" },
    "test":  { "command": "xcodebuild test -scheme MyApp -destination 'platform=iOS Simulator,name=iPhone 15'" }
  },
  "screenshots": { "tool": "simctl" }
}

Android (gradle)

{
  "project_type": "android",
  "runners": {
    "build": { "command": "./gradlew assembleDebug" },
    "test":  { "command": "./gradlew test" }
  },
  "screenshots": { "tool": "adb", "device": "emulator-5554" }
}

.NET / WPF

{
  "project_type": "dotnet",
  "runners": {
    "build": { "command": "dotnet build" },
    "test":  { "command": "dotnet test" }
  },

}

Environment variables

Plugin configuration

Drop a .codeloop/plugins.json in the project root to wire any CLI test runner into the verify suite. See the full schema in Plugin SDK. Plugin entries appear next to first-party runners in codeloop_verify output and contribute to the gate score.

Multi-section configuration

Enable sections.enabled = true and create per-section spec / acceptance files. codeloop_section_status reads and writes the state machine; see Multi-section orchestration for the full lifecycle.

Design references

Two paths:

• Figma — .codeloop/figma.json + FIGMA_API_TOKEN env var. See Design compare.
• Local PNG — designs/<screen>/<viewport>.png. No credentials, no network.

OSS plan project marker

If you applied for the free OSS plan via /oss-application, your approval ties the API key to your repo. There is no per-project config to add — the backend resolves the plan from the key itself.

Self-host configuration

Point CODELOOP_API_URL at your stack and set CODELOOP_MODE=local. See Self-host runbook for the full Docker Compose env reference.
