+## Claude Code
+
+Install skills to let Claude Code manage CloudAMQP instances on your behalf:
+
+```bash
+cloudamqp install skills
+```
+
+This copies skills to `~/.claude/skills/cloudamqp-cli/`. Claude Code discovers them automatically.

+name: cloudamqp-cli
+description: Manage CloudAMQP instances, VPCs, teams, and RabbitMQ/LavinMQ configuration from the command line. Use when the user needs to create, configure, monitor, upgrade, or troubleshoot CloudAMQP message broker instances.
+allowed-tools: Bash(cloudamqp:*)
+---
+
+# CloudAMQP CLI
+
+## Quick start
+
+```bash
+# list all instances
+cloudamqp instance list
+
+# get instance details (includes connection URL and API key)
+cloudamqp instance get --id 1234
+
+# create an instance and wait for it to be ready
+cloudamqp instance create --name=my-instance --plan=bunny-1 --region=amazon-web-services::us-east-1 --wait
+
+# restart RabbitMQ on an instance
+cloudamqp instance restart-rabbitmq --id 1234
+
+# delete an instance
+cloudamqp instance delete --id 1234
+```
+
+## Authentication
+
+Before running any commands, check that auth is configured — the CLI won't work without it and can't prompt interactively when run by an agent.
+
+```bash
+# check if already configured
+cat ~/.cloudamqprc 2>/dev/null || echo "not configured"
+
+# if not set up, ask the user for their API key, then write it:
+echo "YOUR_API_KEY" > ~/.cloudamqprc
+chmod 600 ~/.cloudamqprc
+```
+
+The CLI checks in this order:
+
+1. `CLOUDAMQP_APIKEY` environment variable
+2. `~/.cloudamqprc` file (plain text, just the key)
+3. Interactive prompt (won't work in agent context — use one of the above)
+
+Base URL defaults to `https://customer.cloudamqp.com/api` (override with `CLOUDAMQP_URL`).
+
+## Output
+
+All commands support `-o json` for machine-readable output and `-o table` (default) for human-readable output. Use `-fields` to select specific columns.
+
+## Commands
+
+### Instance lifecycle
+
+```bash
+cloudamqp instance create --name=<name> --plan=<plan> --region=<region> [--tags=<tag>...] [--vpc-id=<id>] [--wait] [--wait-timeout=20m]
+cloudamqp instance list [--details]
+cloudamqp instance get --id <id>
+cloudamqp instance update --id <id> [--name=<name>] [--plan=<plan>]
+cloudamqp instance delete --id <id> [--force]
+cloudamqp instance resize-disk --id <id> --disk-size=<gb> [--allow-downtime]
+```
+
+### Copy settings between instances
+
+```bash
+cloudamqp instance create --name=staging --plan=bunny-1 --region=amazon-web-services::us-east-1 \
+  --copy-from-id=1234 --copy-settings=metrics,firewall,config,alarms,logs,definitions,plugins --wait
+```
+
+Only works between dedicated instances (not shared plans).
+
+### Node management
+
+```bash
+cloudamqp instance nodes list --id <id>
+cloudamqp instance nodes versions --id <id>
+```
+
+### Plugin management
+
+```bash
+cloudamqp instance plugins list --id <id>
+```
+
+### RabbitMQ configuration
+
+```bash
+cloudamqp instance config list --id <id>
+cloudamqp instance config get --id <id> --key <key>
+cloudamqp instance config set --id <id> --key <key> --value <value>
+```
+
+### Instance actions
+
+```bash
+# restart
+cloudamqp instance restart-rabbitmq --id <id> [--nodes=node1,node2]
+cloudamqp instance restart-cluster --id <id>
+cloudamqp instance restart-management --id <id> [--nodes=node1,node2]
+
+# start/stop
+cloudamqp instance start --id <id> [--nodes=node1,node2]
+cloudamqp instance stop --id <id> [--nodes=node1,node2]
+cloudamqp instance reboot --id <id> [--nodes=node1,node2]
+cloudamqp instance start-cluster --id <id>
+cloudamqp instance stop-cluster --id <id>
+
+# upgrades (async, return immediately)
+cloudamqp instance upgrade-erlang --id <id>
+cloudamqp instance upgrade-rabbitmq --id <id> --version=<version>
+cloudamqp instance upgrade-all --id <id>
+cloudamqp instance upgrade-versions --id <id>
+```
+
+### VPC management
+
+```bash
+cloudamqp vpc create --name=<name> --region=<region> --subnet=<cidr> [--tags=<tag>]
+cloudamqp vpc list
+cloudamqp vpc get --id <id>
+cloudamqp vpc update --id <id> --name=<name>
+cloudamqp vpc delete --id <id>
+```
+
+### Team management
+
+```bash
+cloudamqp team list
+cloudamqp team invite --email=<email> [--role=<role>] [--tags=<tag>]
+cloudamqp team update --user-id=<id> --role=<role>
+cloudamqp team remove --email=<email>
+```
+
+### Audit log
+
+```bash
+cloudamqp audit [--timestamp=2024-01]
+```
+
+### API key rotation
+
+```bash
+cloudamqp rotate-key
+```
+
+## Important behavior
+
+- **Async operations**: Instance creation, disk resizes, and upgrades are async. Use `--wait` on create, or poll with `instance get --id <id>` until `ready: true`.
+- **Destructive commands** (delete, stop) prompt for confirmation. Use `--force` to skip in scripts.
+- **Multiple tags**: Use `--tags` multiple times: `--tags=prod --tags=web`.
+- **Shell completion**: Run `source <(cloudamqp completion zsh)` for tab completion of commands, instance IDs, plans, and regions.
+
+## Plans and regions
+
+Always fetch live data — don't guess plan names or regions:
+
+```bash
+cloudamqp plans [--backend=rabbitmq|lavinmq]
+cloudamqp regions [--provider=amazon-web-services]
+```
+
+## Specific tasks
+
+* **Scripting and automation** [references/scripting.md](references/scripting.md)
+* **Instance upgrades and maintenance** [references/upgrades.md](references/upgrades.md)
+* **VPC and network setup** [references/vpc-setup.md](references/vpc-setup.md)

+# Scripting and automation
+
+## JSON output for parsing
+
+All commands support `-o json` for structured output. Combine with `jq` for extraction:
+
+```bash
+# get connection URL for an instance
+cloudamqp instance get --id 1234 -o json | jq -r '.url'
+
+# list instance IDs matching a tag
+cloudamqp instance list -o json | jq -r '.[] | select(.tags[]? == "production") | .id'
+
+# get all instance names and plans
+cloudamqp instance list -o json | jq -r '.[] | "\(.id) \(.name) \(.plan)"'
+```
+
+## Create and capture instance ID
+
+```bash
+RESULT=$(cloudamqp instance create --name=temp --plan=lemming --region=amazon-web-services::us-east-1 -o json)
+INSTANCE_ID=$(echo "$RESULT" | jq -r '.id')
+echo "Created instance: $INSTANCE_ID"
+```
+
+## Wait for instance readiness
+
+Use the built-in `--wait` flag (default timeout: 15 minutes):
+
+```bash
+cloudamqp instance create --name=my-instance --plan=bunny-1 \
+  --region=amazon-web-services::us-east-1 --wait --wait-timeout=20m
+```
+
+Or poll manually:
+
+```bash
+while true; do
+  STATUS=$(cloudamqp instance get --id "$INSTANCE_ID" -o json | jq -r '.ready')
+  [ "$STATUS" = "true" ] && break
+  sleep 30
+done
+```
+
+## Skip confirmations
+
+Use `--force` on destructive commands:
+
+```bash
+cloudamqp instance delete --id 1234 --force
+```
+
+## Environment-based configuration
+
+```bash
+export CLOUDAMQP_APIKEY="your-api-key"
+cloudamqp instance list  # no prompts
+```
+
+## Batch operations
+
+```bash
+# restart all instances tagged "staging"
+for ID in $(cloudamqp instance list -o json | jq -r '.[] | select(.tags[]? == "staging") | .id'); do
+  echo "Restarting instance $ID"
+  cloudamqp instance restart-rabbitmq --id "$ID"
+done
+```
+
+## Clone an instance with full config
+
+```bash
+cloudamqp instance create \
+  --name=staging-copy \
+  --plan=bunny-1 \
+  --region=amazon-web-services::us-east-1 \
+  --copy-from-id=1234 \
+  --copy-settings=alarms,metrics,logs,firewall,config,definitions,plugins \
+  --wait
+```
