The Skills CLI recognizes several environment variables that control its behavior.

​
Telemetry Control

Both DISABLE_TELEMETRY and DO_NOT_TRACK have the same effect. Use whichever you prefer.

​
Skill Discovery

​
GitHub Authentication

​
CI Detection

The CLI automatically detects CI environments and adjusts behavior (e.g., disables telemetry). These variables are read-only (set by CI platforms, not by users).
Generic CI environment indicatorSet by: Most CI platforms
Example: CI=true
GitHub Actions environmentSet by: GitHub Actions
Example: GITHUB_ACTIONS=true
GitLab CI environmentSet by: GitLab CI/CD
Example: GITLAB_CI=true
CircleCI environmentSet by: CircleCI
Example: CIRCLECI=true
Travis CI environmentSet by: Travis CI
Example: TRAVIS=true
Buildkite environmentSet by: Buildkite
Example: BUILDKITE=true
Jenkins environmentSet by: Jenkins
Example: JENKINS_URL=https://jenkins.example.com
TeamCity environmentSet by: TeamCity
Example: TEAMCITY_VERSION=2023.11
When any CI variable is detected, the CLI automatically:
  • Disables telemetry (unless explicitly re-enabled)
  • Adds ci=1 flag to any telemetry that is sent
  • May adjust interactive prompts (some CI platforms)
