-Note: version 0.1.x is a full rewrite and we do not have proper documentation for it yet. Should have this out week of June 17th 2025
+### Installation
 
-## Installation
-
-### Curl
-
-```
+```bash
+# YOLO
 curl -fsSL https://opencode.ai/install | bash
+
+# Package managers
+npm i -g opencode-ai@latest        # or bun/pnpm/yarn
+brew install sst/tap/opencode      # macOS
+paru -S opencode-bin               # Arch Linux
 ```
 
-### NPM
+> [!TIP]
+> Remove versions older than 0.1.x before installing.
 
-```
-npm i -g opencode-ai@latest
-bun i -g opencode-ai@latest
-pnpm i -g opencode-ai@latest
-yarn global add opencode-ai@latest
+#### Installation Directory
+
+The install script respects the following priority order for the installation path:
+
+1. `$OPENCODE_INSTALL_DIR` - Custom installation directory
+2. `$XDG_BIN_DIR` - XDG Base Directory Specification compliant path
+3. `$HOME/bin` - Standard user binary directory (if exists or can be created)
+4. `$HOME/.opencode/bin` - Default fallback
+
+```bash
+# Examples
+OPENCODE_INSTALL_DIR=/usr/local/bin curl -fsSL https://opencode.ai/install | bash
+XDG_BIN_DIR=$HOME/.local/bin curl -fsSL https://opencode.ai/install | bash
 ```
 
-### Brew

+
+### Contributing
+
+opencode is an opinionated tool so any fundamental feature needs to go through a
+design process with the core team.
+
+> [!IMPORTANT]
+> We do not accept PRs for core features.
+
+However we still merge a ton of PRs - you can contribute:
+
+- Bug fixes
+- Improvements to LLM performance
+- Support for new providers
+- Fixes for env specific quirks
+- Missing standard behavior
+- Documentation
+
+Take a look at the git history to see what kind of PRs we end up merging.
+
+> [!NOTE]
+> If you do not follow the above guidelines we might close your PR.
+
+To run opencode locally you need.
+
+- Bun
+- Golang 1.24.x
+
+And run.
+
+```bash
+$ bun install
+$ bun dev
 ```
 
-### AUR
+#### Development Notes
 
-```
-paru -S opencode-bin
-```
+**API Client**: After making changes to the TypeScript API endpoints in `packages/opencode/src/server/server.ts`, you will need the opencode team to generate a new stainless sdk for the clients.
+
+### FAQ
+
+#### How is this different than Claude Code?
+
+It's very similar to Claude Code in terms of capability. Here are the key differences:
+
+- 100% open source
+- Not coupled to any provider. Although Anthropic is recommended, opencode can be used with OpenAI, Google or even local models. As models evolve the gaps between them will close and pricing will drop so being provider-agnostic is important.
+- A focus on TUI. opencode is built by neovim users and the creators of [terminal.shop](https://terminal.shop); we are going to push the limits of what's possible in the terminal.
+- A client/server architecture. This for example can allow opencode to run on your computer, while you can drive it remotely from a mobile app. Meaning that the TUI frontend is just one of the possible clients.
+
+#### What's the other repo?
+
+The other confusingly named repo has no relation to this one. You can [read the story behind it here](https://x.com/thdxr/status/1933561254481666466).

+# opencode GitHub Action
+
+A GitHub Action that integrates [opencode](https://opencode.ai) directly into your GitHub workflow.
+
+Mention `/opencode` in your comment, and opencode will execute tasks within your GitHub Actions runner.
+
+## Features
+
+#### Explain an issues
+
+Leave the following comment on a GitHub issue. `opencode` will read the entire thread, including all comments, and reply with a clear explanation.
+
+```
+/opencode explain this issue
+```
+
+#### Fix an issues
+
+Leave the following comment on a GitHub issue. opencode will create a new branch, implement the changes, and open a PR with the changes.
+
+```
+/opencode fix this
+```
+
+#### Review PRs and make changes
+
+Leave the following comment on a GitHub PR. opencode will implement the requested change and commit it to the same PR.
+
+```
+Delete the attachment from S3 when the note is removed /oc
+```
+
+## Installation
+
+Run the following command in the terminal from your GitHub repo:
+
+```bash
+opencode github install
+```
+
+This will walk you through installing the GitHub app, creating the workflow, and setting up secrets.
+
+### Manual Setup
+
+1. Install the GitHub app https://github.com/apps/opencode-agent. Make sure it is installed on the target repository.
+2. Add the following workflow file to `.github/workflows/opencode.yml` in your repo. Set the appropriate `model` and required API keys in `env`.
+
+   ```yml
+   name: opencode
+
+   on:
+     issue_comment:
+       types: [created]
+
+   jobs:
+     opencode:
+       if: |
+         contains(github.event.comment.body, '/oc') ||
+         contains(github.event.comment.body, '/opencode')
+       runs-on: ubuntu-latest
+       permissions:
+         id-token: write
+       steps:
+         - name: Checkout repository
+           uses: actions/checkout@v4
+           with:
+             fetch-depth: 1
+
+         - name: Run opencode
+           uses: sst/opencode/github@latest
+           env:
+             ANTHROPIC_API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
+           with:
+             model: anthropic/claude-sonnet-4-20250514
+   ```
+
+3. Store the API keys in secrets. In your organization or project **settings**, expand **Secrets and variables** on the left and select **Actions**. Add the required API keys.
+
+## Support
+
+This is an early release. If you encounter issues or have feedback, please create an issue at https://github.com/sst/opencode/issues.
+
+## Development
+
+To test locally:
+
+1. Navigate to a test repo (e.g. `hello-world`):
+
+   ```bash
+   cd hello-world
+   ```
+
+2. Run:
+
+   ```bash
+   MODEL=anthropic/claude-sonnet-4-20250514 \
+     ANTHROPIC_API_KEY=sk-ant-api03-1234567890 \
+     GITHUB_RUN_ID=dummy \
+     bun /path/to/opencode/packages/opencode/src/index.ts github run \
+     --token 'github_pat_1234567890' \
+     --event '{"eventName":"issue_comment",...}'
+   ```
+
+   - `MODEL`: The model used by opencode. Same as the `MODEL` defined in the GitHub workflow.
+   - `ANTHROPIC_API_KEY`: Your model provider API key. Same as the keys defined in the GitHub workflow.
+   - `GITHUB_RUN_ID`: Dummy value to emulate GitHub action environment.
+   - `/path/to/opencode`: Path to your cloned opencode repo. `bun /path/to/opencode/packages/opencode/src/index.ts` runs your local version of `opencode`.
+   - `--token`: A GitHub persontal access token. This token is used to verify you have `admin` or `write` access to the test repo. Generate a token [here](https://github.com/settings/personal-access-tokens).
+   - `--event`: Mock GitHub event payload (see templates below).
+
+### Issue comment event
+
+```
+--event '{"eventName":"issue_comment","repo":{"owner":"sst","repo":"hello-world"},"actor":"fwang","payload":{"issue":{"number":4},"comment":{"id":1,"body":"hey opencode, summarize thread"}}}'
+```
+
+Replace:
+
+- `"owner":"sst"` with repo owner
+- `"repo":"hello-world"` with repo name
+- `"actor":"fwang"` with the GitHub username of commentor
+- `"number":4` with the GitHub issue id
+- `"body":"hey opencode, summarize thread"` with comment body
+
+### Issue comment with image attachment.
+
+```
+--event '{"eventName":"issue_comment","repo":{"owner":"sst","repo":"hello-world"},"actor":"fwang","payload":{"issue":{"number":4},"comment":{"id":1,"body":"hey opencode, what is in my image ![Image](https://github.com/user-attachments/assets/xxxxxxxx)"}}}'
+```
+
+Replace the image URL `https://github.com/user-attachments/assets/xxxxxxxx` with a valid GitHub attachment (you can generate one by commenting with an image in any issue).
+
+### PR comment event
+
+```
+--event '{"eventName":"issue_comment","repo":{"owner":"sst","repo":"hello-world"},"actor":"fwang","payload":{"issue":{"number":4,"pull_request":{}},"comment":{"id":1,"body":"hey opencode, summarize thread"}}}'
+```

+You are an elite AI agent architect specializing in crafting high-performance agent configurations. Your expertise lies in translating user requirements into precisely-tuned agent specifications that maximize effectiveness and reliability.
+
+**Important Context**: You may have access to project-specific instructions from CLAUDE.md files and other context that may include coding standards, project structure, and custom requirements. Consider this context when creating agents to ensure they align with the project's established patterns and practices.
+
+When a user describes what they want an agent to do, you will:
+
+1. **Extract Core Intent**: Identify the fundamental purpose, key responsibilities, and success criteria for the agent. Look for both explicit requirements and implicit needs. Consider any project-specific context from CLAUDE.md files. For agents that are meant to review code, you should assume that the user is asking to review recently written code and not the whole codebase, unless the user has explicitly instructed you otherwise.
+
+2. **Design Expert Persona**: Create a compelling expert identity that embodies deep domain knowledge relevant to the task. The persona should inspire confidence and guide the agent's decision-making approach.
+
+3. **Architect Comprehensive Instructions**: Develop a system prompt that:
+
+   - Establishes clear behavioral boundaries and operational parameters
+   - Provides specific methodologies and best practices for task execution
+   - Anticipates edge cases and provides guidance for handling them
+   - Incorporates any specific requirements or preferences mentioned by the user
+   - Defines output format expectations when relevant
+   - Aligns with project-specific coding standards and patterns from CLAUDE.md
+
+4. **Optimize for Performance**: Include:
+
+   - Decision-making frameworks appropriate to the domain
+   - Quality control mechanisms and self-verification steps
+   - Efficient workflow patterns
+   - Clear escalation or fallback strategies
+
+5. **Create Identifier**: Design a concise, descriptive identifier that:
+   - Uses lowercase letters, numbers, and hyphens only
+   - Is typically 2-4 words joined by hyphens
+   - Clearly indicates the agent's primary function
+   - Is memorable and easy to type
+   - Avoids generic terms like "helper" or "assistant"
+
+6 **Example agent descriptions**:
+
+- in the 'whenToUse' field of the JSON object, you should include examples of when this agent should be used.
+- examples should be of the form:
+  - <example>
+      Context: The user is creating a code-review agent that should be called after a logical chunk of code is written.
+      user: "Please write a function that checks if a number is prime"
+      assistant: "Here is the relevant function: "
+      <function call omitted for brevity only for this example>
+      <commentary>
+      Since the user is greeting, use the Task tool to launch the greeting-responder agent to respond with a friendly joke. 
+      </commentary>
+      assistant: "Now let me use the code-reviewer agent to review the code"
+    </example>
+  - <example>
+      Context: User is creating an agent to respond to the word "hello" with a friendly jok.
+      user: "Hello"
+      assistant: "I'm going to use the Task tool to launch the greeting-responder agent to respond with a friendly joke"
+      <commentary>
+      Since the user is greeting, use the greeting-responder agent to respond with a friendly joke. 
+      </commentary>
+    </example>
+- If the user mentioned or implied that the agent should be used proactively, you should include examples of this.
+- NOTE: Ensure that in the examples, you are making the assistant use the Agent tool and not simply respond directly to the task.
+
+Your output must be a valid JSON object with exactly these fields:
+{
+"identifier": "A unique, descriptive identifier using lowercase letters, numbers, and hyphens (e.g., 'code-reviewer', 'api-docs-writer', 'test-generator')",
+"whenToUse": "A precise, actionable description starting with 'Use this agent when...' that clearly defines the triggering conditions and use cases. Ensure you include examples as described above.",
+"systemPrompt": "The complete system prompt that will govern the agent's behavior, written in second person ('You are...', 'You will...') and structured for maximum clarity and effectiveness"
+}
+
+Key principles for your system prompts:
+
+- Be specific rather than generic - avoid vague instructions
+- Include concrete examples when they would clarify behavior
+- Balance comprehensiveness with clarity - every instruction should add value
+- Ensure the agent has enough context to handle variations of the core task
+- Make the agent proactive in seeking clarification when needed
+- Build in quality assurance and self-correction mechanisms
+
+Remember: The agents you create should be autonomous experts capable of handling their designated tasks with minimal additional guidance. Your system prompts are their complete operational manual.
