+
+# argc Plugin
+
+argc is a Bash CLI framework that turns bash scripts into full-featured command-line tools with help messages, argument validation, and shell completions.
+
+## Commands
+
+### Basic
+- `argc self version` — Print argc version
+- `argc help show` — Show argc help
+
+### Script Execution
+- `argc script run` — Run a bash script with argc annotations
+
+### Shell Integration
+- `argc completions generate` — Generate shell completions (bash/zsh/fish/powershell/elvish)
+
+### Passthrough
+- `argc _ _` — Pass raw arguments to argc binary
+
+## Usage Examples
+
+```bash
+# Show argc help
+sc argc help show --json
+
+# Run a script with argc annotations
+sc argc script run myscript.sh -- --help
+
+# Generate bash completions
+sc argc completions generate bash
+```

+# sccache Plugin
+
+sccache is a compiler caching tool (like ccache) with support for local and cloud storage backends (S3, GCS, Azure, Redis).
+
+## Commands
+
+### Version Info
+- `sccache self version` — Print sccache version
+
+### Cache Management
+- `sccache stats show` — Show cache statistics (hits, misses, size)
+- `sccache cache clear` — Clear the entire cache
+
+### Server Management
+- `sccache server start` — Start the sccache daemon
+- `sccache server stop` — Stop the sccache daemon
+
+### Passthrough
+- `sccache _ _` — Pass raw arguments to sccache binary
+
+## Usage Examples
+
+```bash
+# Check cache stats
+sc sccache stats show --json
+
+# Clear cache
+sc sccache cache clear
+
+# Use sccache as compiler wrapper
+export RUSTC_WRAPPER=sccache
+cargo build
+sc sccache stats show --json
+```
