Opencode Agentic toolkit

Inspired by https://github.com/rstacruz/agentic-toolkit/tree/main

Collection of what agentic toolkit that I find useful on my everyday workflow. I recommend browsing command/ and skill/ and taking what you need.

Pre-requisites

1. Install OpenCode.
2. Set up artefacts directories:

• Add to global gitignore: echo artefacts >> ~/.config/git/global_ignore (or wherever your global ignore is)
• I instruct AI agents to make a log of approved plans and changes inside artefacts/ for easier session/model switching

3. Pick-and-choose what you want to copy:

• Copy command/ files into ~/.config/opencode/command/
• Copy skill/ files into ~/.config/opencode/skill/ (ensure you use OpenCode 1.0.190+)

Core tools

Continue from here

/continue-from-here command

One of my favourite ways to work! Forget prompting, just add comments. Inspired by Aider's watch files mode.

• works best when you have clean git state
• add // AI: comments around your code.
• run /continue-from-here.

// schema.prisma
model Word {
  id   String @id @default(uuid())
  word String
  // AI: add `language` column

  @@unique([lang, word])
  @@map("words")
}

// word.ts
function getWord(word: string /* AI: also query by `language` */ ) {
  // AI: use validateWord here
    return db.word.where({ word })
}

function validateWord(wordObject) {
  // AI: implement this. add typescript types to the params
}

Plan mode

/plan command

Ask the agent to confirm actions before doing them. Unlike OpenCode's built in plan mode:

• No need to switch to plan/build agents
• More eager to get your input with questions
• stores approved plans and changes inside the current project's artefacts/
• answering Agent questions is easy as multiple choice questionnaire

I use this:

• As a replacement for the built-in plan mode
• For almost every change (/plan change test names to be descriptive → (answer q's) → go)

## User

/plan add dark mode toggle to settings

## Assistant

**Plan mode engaged.**

[Researches codebase, creates todo list]

Before I draft the plan, I have a clarifying question:

1. **Theme detection:** Should the app detect system theme preference automatically?
   - a. Yes, respect system preference (recommended)
   - b. No, manual toggle only

Here's the implementation plan:

1. Add theme context provider with system detection
2. Create toggle component in settings page
3. Update CSS with theme variables
4. Persist preference to localStorage

Ready when you say **go**.
