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

bash
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

bash
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/
.
FlagPurpose
--name <name>
Install a specific skill by name
--all
Install all available skills

installed — show what's installed locally

bash
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

bash
asc skills uninstall --name <name>
Removes the skill directory from 
~/.claude/skills/
.

check — check for skill updates

bash
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

bash
asc skills update
Delegates to 
npx skills update
to pull the latest versions.

Typical Workflow

bash
# 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)

ASC_SKIP_SKILL_CHECK=true

How it works

  1. Runs 
    npx skills check
    (offline mode for passive checks)
  2. Parses stdout: looks for "update(s) available" vs "up to date" / "no update"
  3. If updates found → prints hint to stderr: 
    Skill updates available. Run 'asc skills update' to refresh installed skills.
  4. 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

json
{
  "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.
