+# Script Shortcuts
+
+Clash Premium implements the Scripting feature powered by Python3, enableing users to programmatically select policies for the packets with dynamic flexibility.
+
+You can either controll the entire rule-matching engine with a single Python script, or define a number of shortcuts and use them in companion with the regular rules. This page refers to the latter feature, for the former, see [Script](./script.md).
+
+This feature enables the use of script in `rules` mode. By default, DNS resolution takes place for SCRIPT rules. `no-resolve` can be appended to the rule to prevent the resolution. (i.e.: `SCRIPT,quic,DIRECT,no-resolve`)
+
+**NOTE: ****`src_port`**** and ****`dst_port`**** are number**
+
+```yaml
+mode: Rule
+
+script:
+  shortcuts:
+    quic: network == 'udp' and dst_port == 443
+    curl: resolve_process_name() == 'curl'
+    # curl: resolve_process_path() == '/usr/bin/curl'
+
+rules:
+  - SCRIPT,quic,REJECT
+```
+
+## Function Definitions
+
+```ts
+type resolve_ip = (host: string) => string // ip string
+type in_cidr = (ip: string, cidr: string) => boolean // ip in cidr
+type geoip = (ip: string) => string // country code
+type match_provider = (name: string) => boolean // in rule provider
+type resolve_process_name = () => string // find process name (curl .e.g)
+type resolve_process_path = () => string // find process path (/usr/bin/curl .e.g)
+```
