opencode-skills-autocomplete

An opencode plugin that lists every available skill in the / menu. After selecting a skill, type a standalone / to open a searchable skill list and add another one. Selecting a skill inserts /name into the prompt at the cursor. The plugin never submits.

Install

Add the package to the plugin array in your tui.json. opencode installs named npm packages automatically at startup and caches them.

{
    "plugin": ["opencode-skills-autocomplete"]
}

To pin a version:

{
    "plugin": ["[email protected]"]
}

The plugin requires opencode 1.15.6 or newer and does not run on opencode 2.x. See opencode version requirement.

Usage

Every skill opencode discovers appears as a row in the / menu, one row per skill, in A-to-Z case-insensitive order. The menu is shared with opencode's built-in rows, which the menu interleaves in its own order. Each row shows the skill name and its origin in the description column:

• (user): the skill lives under your home or config directories
• (project): the skill lives inside the current project worktree
• (built-in): the skill ships with opencode

Type in the / menu to filter. Matching is case-insensitive and covers the skill name only, using the menu's own filter.

Selecting a skill inserts /name at the cursor, with a trailing space. opencode does not submit a prompt that contains only /name, so the trailing space is what makes a skill-only prompt sendable: press Enter to run the skill.

Type a standalone / after the first skill to open the searchable Skills dialog. Select another skill to keep both in the prompt, for example /grilling /tdd . Press Esc to close either menu and keep the / you typed at the cursor.

A / is standalone when the character directly before it is whitespace (such as a space, tab, or line break) or the start of the prompt, and the character directly after it is whitespace or the end of the prompt. Any other / is plain text and opens no menu:

• fix this / opens the Skills dialog.
• path/to/file, http://, and see (/ type a plain /.
• With the cursor directly before more in ask more (after the space), a typed / is a plain / in front of more.

The rule covers opencode's own / menu too:

• A / typed at the start of the prompt directly before text, or in the first word of a prompt that starts with /, is plain text and opens no menu.
• If that menu is already open, a / typed at the very start closes it.
• An empty prompt, or a / at the start before whitespace, still opens the menu.
• Typing more characters in that first word can open the menu again.

Keyboard shortcut

ctrl+s by default opens the command palette without typing /. OpenCode uses ctrl+k to delete to the end of the input line, so the plugin cannot use that key unless you free it in your TUI keybinds. Configure the shortcut with the hotkey option below.

The hotkey option

The shortcut takes a single opencode keybind and defaults to ctrl+s:

{
    "plugin": [["opencode-skills-autocomplete", { "hotkey": "ctrl+shift+k" }]]
}

It has to be one keypress with a modifier held, so ctrl+shift+k works. k+k is two keys in a row, and a bare k, space, or escape would swallow that key as you type.

If the key is already bound in your effective keybinds, or it cannot be a shortcut, the plugin shows a warning toast naming the reason and leaves the shortcut off. The / menu keeps working.

opencode version requirement

This plugin runs on opencode 1.x, version 1.15.6 or newer. 1.15.6 is the first opencode release that ships every TUI API the plugin calls, and the manifest declares engines.opencode: ">=1.15.6".

On an older opencode 1.x the loader skips the plugin and says nothing: the reason goes to standard error, which the TUI never shows. The symptom is a / menu with no skill rows, so check your opencode version first.

This plugin does not run on opencode 2.x, which renames the plugin contract. opencode 2.x installs the plugin, loads it, and then shows a "Plugin failed" toast. Supporting 2.x needs a rewrite against the new contract and will come in a later major version of this plugin. There is no date for it.

1.0.0 is the last release to add opencode 1.x support. From here the 1.x line takes bug fixes only. The 1.x bug-fix-only ADR has the reasoning.

Development

Requires bun.

bun install

| Script | What it does | | ------------------- | --------------------------------------------- | | bun run check | Biome lint and format check over the repo | | bun run typecheck | TypeScript check over the source and test | | bun run test | Vitest unit and integration tests | | bun run spell | cspell over all Markdown files | | bun run build | Builds dist/, the plugin entry plus types |

More on the test layout and how changes land in docs/development.md.

Manual smoke checklist

Run these in a fresh TUI after changes that touch skill registration or paste behavior. Use a project with at least one user-level, one project-level, and one built-in skill.

1. Open the / menu. Each skill shows as a row, in A-to-Z order, with the right (user), (project), or (built-in) tag. Press Esc: the menu closes and / stays in the prompt.
2. Reopen the / menu and type a few letters. The list filters by name, case-insensitively.
3. Select a skill. The prompt gains /name with a trailing space at the cursor, and the prompt is not submitted.
4. Type a standalone / (a space before it, nothing after it), filter the Skills dialog, and select a second skill. Both /name entries remain in the prompt. Open the dialog again and press Esc: the typed / remains at the cursor.
5. Type path/ in an empty prompt, then /. The first / opens no menu and the second opens the Skills dialog.
6. Clear the prompt, type abc, press Home, and type /. The prompt reads /abc and no menu opens.
7. Clear the prompt, type /ab, and press Esc. Move the cursor between a and b, and type /. The prompt reads /a/b and no menu opens.
8. Clear the prompt, type /ab with opencode's menu open, press Home, and type /. The menu closes and the prompt reads //ab.
9. With only /name in the prompt, press Enter. The skill runs.
10. Press ctrl+s, or your configured hotkey. The command palette opens with the same rows.
11. Set hotkey to a key you already bind (for example ctrl+p) and restart. A toast reads hotkey "ctrl+p" will not work, it is already bound, the key does what it did before, and the / menu still works.
12. Set hotkey to k+k, restart, and do it again with a bare k. The toasts read it is more than one key and single keys are not allowed, and typing k still reaches the prompt.

Listing the plugin

One-time, manual work after the first release. Neither list has an API or a per-release path:

• Open a PR to add the plugin to the opencode ecosystem list.
• Open a PR to add the plugin to awesome-opencode.

Reporting bugs

Open a public issue with the bug report template; details in docs/bug-reporting.md.
