Install

Three steps: authenticate to AWS, clone the repo, launch Claude with the plugin directories.

1. Authenticate to magellan

aws login --profile magellan

A browser opens. Sign in with your ACN credentials and select the Admin role on magellan-aws. Confirm:

aws sts get-caller-identity --profile magellan
# Should return Account 310378384655

2. Clone the toolkit

git clone codecommit::us-east-2://magellan@acn-claude-toolkit ~/acn-claude-toolkit

Pick any path you like. The examples below assume ~/acn-claude-toolkit.

3. Launch Claude Code with —plugin-dir

The flag is --plugin-dir, not --add-dir. It loads plugins from a local directory, bypassing the enterprise marketplace allowlist.

Option A — explicit per-plugin launch

# Single plugin
claude --plugin-dir ~/acn-claude-toolkit/plugins/acn-base-sdlc

# Multiple plugins (the flag is repeatable)
claude \
  --plugin-dir ~/acn-claude-toolkit/plugins/acn-base-sdlc \
  --plugin-dir ~/acn-claude-toolkit/plugins/acn-slide-gen \
  --plugin-dir ~/acn-claude-toolkit/plugins/acn-pursuit-toolkit

Option B — shell function (recommended)

Add to your ~/.zshrc or ~/.bashrc:

claude-acn() {
  local toolkit="$HOME/acn-claude-toolkit"
  claude \
    --plugin-dir "$toolkit/plugins/acn-base-sdlc" \
    --plugin-dir "$toolkit/plugins/acn-slide-gen" \
    --plugin-dir "$toolkit/plugins/acn-pursuit-toolkit" \
    "$@"
}

Reload your shell, then:

claude-acn                  # launch with toolkit
claude-acn --resume         # other claude flags pass through

For the rationale behind --plugin-dir instead of /plugin marketplace add, see --plugin-dir vs marketplace.

Next

Run your first command to verify the install.
