## What it does

The skill walks an agent through the signing chain for iOS and macOS apps using the `asc` CLI: bundle IDs, capabilities, certificates, profiles. It runs the commands itself, from `asc bundle-ids create` to `asc profiles download` and `asc profiles local install`. Rotation is covered too, with `asc certificates revoke` and `asc profiles delete`.

Working auth comes first: `asc auth login` or the `ASC_*` environment variables. You also need the bundle identifier, the target platform, and a CSR file, or `--generate-csr` to make the key and request inline. Some things the public API cannot do. `PRIVATE_CLOUD_COMPUTE` only turns on through a Developer Portal web session, and App Groups need an Account Holder or Admin session — changing the assignment invalidates profiles that carry that App ID.

\`asc signing sync` handles shared storage: encrypted certificates and profiles in git, non-interactive, described as a lighter alternative to fastlane match. App Store Connect never returns a private key, so `push` takes a local PKCS#12 via `--identity`. Pass the password as a file with `--password-file`; `--password` was removed in 5.0.0 and `ASC_MATCH_PASSWORD` is ignored. An old call in CI will fail outright, so check the scripts before a release.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-signing-setup -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/asc-signing-setup/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/asc-signing-setup/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-signing-setup -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/asc-signing-setup/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-signing-setup -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/asc-signing-setup/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install rorkai/app-store-connect-cli-skills asc-signing-setup
```

2. **Manually: put the files in place**

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-signing-setup -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/rorkai/app-store-connect-cli-skills --path skills/asc-signing-setup
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/asc-signing-setup/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add rorkai/app-store-connect-cli-skills --skill asc-signing-setup -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/rorkai/app-store-connect-cli-skills/tree/HEAD/skills/asc-signing-setup/SKILL.md

## When to use it
- create a bundle ID and turn on the capabilities it needs
- issue an IOS_DISTRIBUTION certificate without a CSR on hand
- build a provisioning profile for App Store or ad-hoc devices
- revoke an old certificate and drop the profiles tied to it
- share signing assets with a team through a git repo

## Example prompts
- Set up signing for a new app with bundle ID com.example.app, an IOS_DISTRIBUTION certificate and an IOS_APP_STORE profile
- Audit profiles in ACTIVE and INVALID state, compare expirationDate with today and delete the expired ones
- Run `asc signing sync pull` from `git@github.com:team/certs.git` with the password in `./signing-sync-password` and decrypt into `./signing`

# 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`
     - 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 "user@example.com"`
       - `asc web auth login --apple-id "user@example.com"`
   - 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`
```
