asc skills

Browse, install, and manage Claude Code agent skills from the tddworks/asc-cli-skills repository. Skills extend your agent with specialized knowledge about App Store Connect workflows — screenshots, TestFlight, code signing, subscriptions, and more.

Commands

list — show available skills from the repository

asc skills list

Lists all skills available for installation from tddworks/asc-cli-skills. Delegates to npx skills add tddworks/asc-cli-skills --list.

install — install skills into your agent

asc skills install --name asc-cli        # install a specific skill
asc skills install --all                 # install all available skills
asc skills install                       # same as --all (default)

Delegates to npx --yes skills add tddworks/asc-cli-skills. Skills are installed to ~/.claude/skills/.

Flag	Purpose
`--name <name>`	Install a specific skill by name
`--all`	Install all available skills

installed — show what's installed locally

asc skills installed [--pretty]

Reads ~/.claude/skills/, parses each skill's SKILL.md frontmatter, and returns structured JSON with CAEOAS affordances.

uninstall — remove an installed skill

asc skills uninstall --name <name>

Removes the skill directory from ~/.claude/skills/.

check — check for skill updates

asc skills check

Delegates to npx skills check. Returns one of:

"All skills are up to date."
"Skill updates are available. Run 'asc skills update' to refresh installed skills."
"Skills CLI is not available. Install with: npm install -g skills"

update — update installed skills

asc skills update

Delegates to npx skills update to pull the latest versions.

Typical Workflow

# First time: install all asc skills
asc skills install --all

# Browse what's available
asc skills list

# Check what you have
asc skills installed --pretty

# Periodically check for updates
asc skills check

# Update when available
asc skills update

# Remove a skill you don't need
asc skills uninstall --name asc-game-center

Auto-Update Checker

A non-blocking update check runs automatically on every asc command. It never interrupts normal CLI flow — failures are silently swallowed.

Guard rails (skip check when any hit)

Condition	Action
`ASC_SKIP_SKILL_CHECK=true` env var	Skip
`CI` or `CONTINUOUS_INTEGRATION` env var set	Skip
Last check was less than 24 hours ago	Skip

How it works

Runs npx skills check (offline mode for passive checks)
Parses stdout: looks for "update(s) available" vs "up to date" / "no update"
If updates found → prints hint to stderr: Skill updates available. Run 'asc skills update' to refresh installed skills.
Saves skillsCheckedAt timestamp to ~/.asc/skills-config.json

Timestamp is only persisted on success — if the skills CLI is unavailable, it retries next time.

JSON Output

`asc skills installed --pretty`

{
  "data": [
    {
      "affordances": {
        "listSkills": "asc skills list",
        "uninstall": "asc skills uninstall --name asc-cli"
      },
      "description": "App Store Connect CLI skill",
      "id": "asc-cli",
      "isInstalled": true,
      "name": "asc-cli"
    }
  ]
}

Installed skills show an uninstall affordance. Not-yet-installed skills show an install affordance instead.
