What is asc-signing-setup?

A tool for setting up the Apple signing items an iOS or macOS app needs, including bundle IDs, capabilities, certificates, and provisioning profiles. It can also synchronize encrypted signing files for a team.

Use it to create or find an app identifier, enable capabilities such as iCloud, create certificates, and manage provisioning and signing files.

It brings the separate Apple Developer signing steps into one documented workflow. This helps when starting an app, renewing credentials, or sharing signing setup with teammates.

Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.

Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
medium Rogue Agent · line 155
Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00046	$0.02103
Opus 5	$0.00023	$0.01052

Security

Grade B, and why

asc-signing-setup scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

Create or find the bundle ID:
- asc bundle-ids list --paginate
- asc bundle-ids create --identifier "com.example.app" --name "Example" --platform IOS
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
  - This capability is not available through the public App Store Connect capability enum. If the cached session cannot access Developer Portal, clear its scoped cache, then log in again with the same binary:
    - asc web auth logout --apple-id "[email protected]"
    - asc web auth login --apple-id "[email protected]"
- For App Groups, the public API can enable APP_GROUPS but cannot create or associate App Group resources. Use an Account Holder or Admin web session:
  - asc web app-groups list --paginate --output table
  - asc web app-groups create --name "Example Shared" --identifier "group.com.example.app.shared" --confirm
  - asc web app-groups assign --group "GROUP_RESOURCE_ID" --bundle-id "BUNDLE_RESOURCE_ID" --confirm
  - Resolve the opaque group ID with asc web app-groups list and the opaque Bundle ID resource ID with asc bundle-ids list. A changed assignment invalidates provisioning profiles containing that App ID, so regenerate affected profiles before the next signed build.
Create a signing certificate:
- asc certificates list --certificate-type IOS_DISTRIBUTION
- asc certificates create --certificate-type IOS_DISTRIBUTION --csr "./cert.csr"
- Or generate a key and CSR inline:
  - asc certificates create --certificate-type IOS_DISTRIBUTION --generate-csr --key-out "./signing/dist.key" --csr-out "./signing/dist.csr"
- For Wallet passes, create the Pass Type ID first, then create its certificate:
  - asc pass-type-ids create --identifier "pass.com.example" --name "Example Pass"
  - asc certificates create --certificate-type PASS_TYPE_ID --pass-type-id "PASS_TYPE_ID" --csr "./pass.csr"
  - asc pass-type-ids certificates list --pass-type-id "PASS_TYPE_ID" --paginate
Create a provisioning profile:
- asc profiles create --name "AppStore Profile" --profile-type IOS_APP_STORE --bundle "BUNDLE_ID" --certificate "CERT_ID"
- Include devices for development/ad-hoc:
  - asc profiles create --name "Dev Profile" --profile-type IOS_APP_DEVELOPMENT --bundle "BUNDLE_ID" --certificate "CERT_ID" --device "DEVICE_ID"
Download the profile:
- asc profiles download --id "PROFILE_ID" --output "./profiles/AppStore.mobileprovision"
Inspect and install the downloaded profile locally when needed:
- asc profiles inspect --path "./profiles/AppStore.mobileprovision" --output table
- asc profiles inspect --path "./profiles/AppStore.mobileprovision" --entitlements --output markdown
- asc profiles local install --path "./profiles/AppStore.mobileprovision"
- asc profiles local list --output table
- On macOS, the default directory follows the active Xcode: Xcode 16 or newer uses ~/Library/Developer/Xcode/UserData/Provisioning Profiles; Xcode 15 or older uses ~/Library/MobileDevice/Provisioning Profiles. Hosts without a full active Xcode fall back to the legacy directory and print a note to stderr.
- Pass --install-dir when automation must target a fixed directory.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
