+# opencode plugin
+
+This plugin adds completion and aliases for the [OpenCode](https://opencode.ai) CLI.
+Install OpenCode using its [installation instructions](https://opencode.ai/docs/#install),
+and make sure `opencode` is available on your `$PATH`.
+
+To enable it, add `opencode` to the plugins array in your `.zshrc`:
+
+```zsh
+plugins=(... opencode)
+```
+
+## Learning OpenCode from the terminal
+
+Use tab completion to explore commands and their descriptions without leaving the
+shell. For example, these are some of the candidates shown by the CLI:
+
+```text
+$ opencode <TAB>
+agent         -- manage agents
+models        -- list all available models
+run           -- run opencode with a message
+session       -- manage sessions
+stats         -- show token usage and cost statistics
+...
+
+$ opencode session <TAB>
+delete        -- delete a session
+list          -- list sessions
+
+$ opencode run --<TAB>
+--agent       -- agent to use
+--continue    -- continue the last session
+--file        -- file(s) to attach to message
+--model       -- model to use in the format of provider/model
+...
+```
+
+Completion works through the aliases too. Type a partial command or option and
+press Tab to finish it:
+
+```text
+$ opc session li<TAB>
+$ opc session list
+
+$ opcr --att<TAB>
+$ opcr --attach
+
+$ opcc --log-l<TAB>
+$ opcc --log-level
+```
+
+Candidates depend on your installed OpenCode version. In OpenCode 1.18.29, the
+CLI's completion output omits top-level TUI flags such as `--model` and `--fork`,
+even though those flags work when typed. Use `opencode --help` or
+`opencode run --help` for the full options, and see the
+[CLI reference](https://opencode.ai/docs/cli/) for more workflows.
+
+## Aliases
+
+| Alias  | Command               | Description                         |
+| ------ | --------------------- | ----------------------------------- |
+| `opc`  | `opencode`            | Launch the terminal UI              |
+| `opcc` | `opencode --continue` | Continue the last session           |
+| `opcr` | `opencode run`        | Run a prompt without opening the UI |
+
+To keep completion but skip the aliases, set this in your `.zshrc`, above the line
+that sources Oh My Zsh:
+
+```zsh
+# ~/.zshrc
+zstyle ':omz:plugins:opencode' aliases no
+
+plugins=(... opencode)
+
+source $ZSH/oh-my-zsh.sh
+```
+
+## Common workflows
+
+All aliases accept additional arguments:
+
+```zsh
+# Open a project
+opc ~/projects/my-app
+
+# Explore a different approach by forking the last session
+opcc --fork
+
+# Ask a question without entering the terminal UI
+opcr "Explain the test setup in this project"
+
+# Reuse an already running backend to avoid MCP server cold starts
+opcr --attach http://localhost:4096 "Explain this project's architecture"
+```
+
+## Completion
+
+Completion queries the installed OpenCode CLI on demand for commands and options,
+including through the aliases above. It falls back to Zsh's default completion when
+the CLI returns no candidates. No OpenCode process is started at shell startup,
+and no generated completion cache is needed.
+
+## Credits
+
+Based on the OpenCode plugin proposals by
+[pranavavva](https://github.com/pranavavva) in
+[#13545](https://github.com/ohmyzsh/ohmyzsh/pull/13545) and
+[mskadu](https://github.com/mskadu) in
+[#13794](https://github.com/ohmyzsh/ohmyzsh/pull/13794).
+The completion adapter is derived from OpenCode's `opencode completion` output.
