+# Obsidian CLI
+
+Use the `obsidian` CLI to interact with a running Obsidian instance. Requires Obsidian to be open.
+
+## Command reference
+
+Run `obsidian help` to see all available commands. This is always up to date. Full docs: https://help.obsidian.md/cli
+
+## Syntax
+
+**Parameters** take a value with `=`. Quote values with spaces:
+
+```bash
+obsidian create name="My Note" content="Hello world"
+```
+
+**Flags** are boolean switches with no value:
+
+```bash
+obsidian create name="My Note" silent overwrite
+```
+
+For multiline content use `\n` for newline and `\t` for tab.
+
+## File targeting
+
+Many commands accept `file` or `path` to target a file. Without either, the active file is used.
+
+- `file=<name>` — resolves like a wikilink (name only, no path or extension needed)
+- `path=<path>` — exact path from vault root, e.g. `folder/note.md`
+
+## Vault targeting
+
+Commands target the most recently focused vault by default. Use `vault=<name>` as the first parameter to target a specific vault:
+
+```bash
+obsidian vault="My Vault" search query="test"
+```
+
+## Common patterns
+
+```bash
+obsidian read file="My Note"
+obsidian create name="New Note" content="# Hello" template="Template" silent
+obsidian append file="My Note" content="New line"
+obsidian search query="search term" limit=10
+obsidian daily:read
+obsidian daily:append content="- [ ] New task"
+obsidian property:set name="status" value="done" file="My Note"
+obsidian tasks daily todo
+obsidian tags sort=count counts
+obsidian backlinks file="My Note"
+```
+
+Use `--copy` on any command to copy output to clipboard. Use `silent` to prevent files from opening. Use `total` on list commands to get a count.
+
+## Plugin development
+
+### Develop/test cycle
+
+After making code changes to a plugin or theme, follow this workflow:
+
+1. **Reload** the plugin to pick up changes:
+   ```bash
+   obsidian plugin:reload id=my-plugin
+   ```
+2. **Check for errors** — if errors appear, fix and repeat from step 1:
+   ```bash
+   obsidian dev:errors
+   ```
+3. **Verify visually** with a screenshot or DOM inspection:
+   ```bash
+   obsidian dev:screenshot path=screenshot.png
+   obsidian dev:dom selector=".workspace-leaf" text
+   ```
+4. **Check console output** for warnings or unexpected logs:
+   ```bash
+   obsidian dev:console level=error
+   ```
+
+### Additional developer commands
+
+Run JavaScript in the app context:
+
+```bash
+obsidian eval code="app.vault.getFiles().length"
+```
+
+Inspect CSS values:
+
+```bash
+obsidian dev:css selector=".workspace-leaf" prop=background-color
+```
+
+Toggle mobile emulation:
+
+```bash
+obsidian dev:mobile on
+```
+
+Run `obsidian help` to see additional developer commands including CDP and debugger controls.
