What is asc-signing-setup?

A setup workflow for Apple app signing, the process that proves an app is authorised to run and be distributed. It manages bundle IDs, capabilities, certificates, provisioning profiles, and encrypted sharing of signing assets.

Use it to create or find bundle IDs, configure capabilities, create certificates and provisioning profiles, and synchronise signing materials securely.

It brings the signing pieces into one repeatable process for new apps, certificate rotation, and team use. It also covers capabilities that control access to Apple platform services.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add hanamizuki/solopreneur --skill asc-signing-setup

Clone the repo

git clone --depth 1 https://github.com/hanamizuki/solopreneur

Made for: Claude Code.

Or install ios-dev, the plugin that ships this one along with the rest of its 26 skills, 1 agent.

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 5.5	$0.00018	$0.00841

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 20d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

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.
