 ### Quick actions
 
-`Patchloom: Quick Action` builds common CLI commands (replace, tidy, doc set) from an interactive picker. Select the operation, pick a target file, and the extension assembles the command with a diff preview before applying.
+`Patchloom: Quick Action` opens an interactive picker with six operations:
+
+| Action | What it does |
+|--------|-------------|
+| **Replace text** | Literal text replacement with diff preview before applying |
+| **Tidy file** | Whitespace and newline cleanup with diff preview |
+| **Set structured value** | Update a JSON, YAML, or TOML key with diff preview |
+| **Search text** | Find pattern matches across workspace files (results in output channel) |
+| **Create file** | Scaffold a new file and open it in the editor |
+| **Read structured value** | Read a JSON/YAML/TOML key and copy to clipboard |
+
+### Batch operations
+
+`Patchloom: Batch Apply` opens a JSON plan template where you can compose multiple operations (replace, tidy, doc set). The extension pipes the plan to `patchloom batch --apply` so all changes land atomically.
+
+### Output channel
+
+All CLI invocations, arguments, and output are logged to the **Patchloom** output channel. Run `Patchloom: Show Output` to open it. Useful for debugging and copying full error messages for bug reports.
