Mem9 Setup

Mem9 Setup

Use this skill when the user asks to set up Mem9, diagnose why memory is not working, or manually retry initialization.

What to check

1. Verify node is installed and version >= 18.
2. Verify ${CLAUDE_PLUGIN_DATA} is available.
3. Check ${CLAUDE_PLUGIN_DATA}/auth.json.

If auth already exists

• Tell the user Mem9 is already initialized.
• Show the auth file path.
• Do not print the file contents or the API key.

If auth is missing

Provision an API key and write ${CLAUDE_PLUGIN_DATA}/auth.json:

set -euo pipefail

plugin_data_dir="${CLAUDE_PLUGIN_DATA}"
test -n "$plugin_data_dir"
node -e 'process.exit(Number(process.versions.node.split(".")[0]) >= 18 ? 0 : 1)'
plugin_version="unknown"
if [ -n "${CLAUDE_PLUGIN_ROOT:-}" ] && [ -f "${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json" ]; then
  plugin_version="$(node -e 'const fs=require("node:fs"); const data=JSON.parse(fs.readFileSync(process.argv[1],"utf8")); process.stdout.write(data.version || "unknown");' "${CLAUDE_PLUGIN_ROOT}/.claude-plugin/plugin.json")"
fi

response="$(curl -sf --max-time 8 -X POST \
  -H "User-Agent: mem9-plugin/claude-code/${plugin_version}" \
  https://api.mem9.ai/v1alpha1/mem9s)"
api_key="$(printf '%s' "$response" | node -e 'const fs=require("node:fs"); const data=JSON.parse(fs.readFileSync(0,"utf8")); process.stdout.write(data.id || "");')"
test -n "$api_key"

auth_file="${plugin_data_dir}/auth.json"
mkdir -p "$(dirname "$auth_file")"
node -e 'const fs=require("node:fs"); const authPath=process.argv[1]; const apiKey=process.argv[2]; const payload={base_url:"https://api.mem9.ai",api_key:apiKey,created_at:new Date().toISOString(),source:"manual_setup_skill"}; fs.writeFileSync(authPath, JSON.stringify(payload, null, 2) + "\n");' "$auth_file" "$api_key"

If setup cannot complete

• If Node is missing, tell the user to install Node.js 18+.
• If ${CLAUDE_PLUGIN_DATA} is missing, tell the user this skill must run from the Mem9 Claude plugin environment.
• If provisioning fails, tell the user Mem9 server could not be reached.
• Never print or quote the API key in the reply.
