Use when onboarding a new app, rotating signing assets, or sharing them across a team. Set up bundle IDs, capabilities, signing certificates, provisioning profiles, and encrypted signing sync with the asc cli.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

# asc signing setup
Use this skill when you need to create or renew signing assets for iOS/macOS apps.
## Preconditions
- Auth is configured (`asc auth login` or `ASC_*` env vars).
- You know the bundle identifier and target platform.
- You have a CSR file for certificate creation, or you will let `asc certificates create --generate-csr` create one.
## Workflow
1. Create or find the bundle ID:
- `asc bundle-ids list --paginate`
- `asc bundle-ids create --identifier "com.example.app" --name "Example" --platform IOS`
2. Configure bundle ID capabilities:
- `asc bundle-ids capabilities list --bundle "BUNDLE_ID"`
- `asc bundle-ids capabilities add --bundle "BUNDLE_ID" --capability ICLOUD`
- Add capability settings when required:
- `--settings '[{"key":"ICLOUD_VERSION","options":[{"key":"XCODE_6","enabled":true}]}]'`
- For the Developer Portal-only `PRIVATE_CLOUD_COMPUTE` capability, use a
user-owned web session and the Developer Portal Bundle ID resource ID:
- `asc web bundle-ids capabilities enable --bundle-id "BUNDLE_RESOURCE_ID" --capability PRIVATE_CLOUD_COMPUTE --confirm`

The line at the top of this page pins the label git:20261028.88809da, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
