-You are an expert technical documentation writer
-
-You are not verbose
-
-The title of the page should be a word or a 2-3 word phrase
-
-The description should be one short line, should not start with "The", should
-avoid repeating the title of the page, should be 5-10 words long
-
-Chunks of text should not be more than 2 sentences long
-
-Each section is separated by a divider of 3 dashes
-
-The section titles are short with only the first letter of the word capitalized
-
-The section titles are in the imperative mood
-
-The section titles should not repeat the term used in the page title, for
-example, if the page title is "Models", avoid using a section title like "Add
-new models". This might be unavoidable in some cases, but try to avoid it.
-
-Check out the /packages/web/src/content/docs/docs/index.mdx as an example.
-
-For JS or TS code snippets remove trailing semicolons and any trailing commas
-that might not be needed.
-
-If you are making a commit prefix the commit message with `docs:`

-- DO NOT use `try`/`catch` if it can be avoided
-- AVOID `try`/`catch` where possible
-- AVOID `else` statements
-- AVOID using `any` type
-- AVOID `let` statements

-## Developing OpenCode
-
-- Requirements: Bun 1.3+
-- Install dependencies and start the dev server from the repo root:
-
-  ```bash
-  bun install
-  bun dev
-  ```
-
-- Core pieces:
-  - `packages/opencode`: OpenCode core business logic & server.
-  - `packages/opencode/src/cli/cmd/tui/`: The TUI code, written in SolidJS with [opentui](https://github.com/sst/opentui)
-  - `packages/plugin`: Source for `@opencode-ai/plugin`
-
-> [!NOTE]
-> After touching `packages/opencode/src/server/server.ts`, run "./packages/sdk/js/script/build.ts" to regenerate the JS sdk.
-
-### Setting up a Debugger
-
-Bun debugging is currently rough around the edges. We hope this guide helps you get set up and avoid some pain points.
-
-The most reliable way to debug OpenCode is to run it manually in a terminal via `bun run --inspect=<url> dev ...` and attach
-your debugger via that URL. Other methods can result in breakpoints being mapped incorrectly, at least in VSCode (YMMV).
-
-Caveats:
-
-- `*.tsx` files won't have their breakpoints correctly mapped. This seems due to Bun currently not supporting source maps on code transformed
-  via `BunPlugin`s (currently necessary due to our dependency on `@opentui/solid`). Currently, the best you can do in terms of debugging `*.tsx`
-  files is writing a `debugger;` statement. Debugging facilities like stepping won't work, but at least you will be informed if a specific code
-  is triggered.
-- If you want to run the OpenCode TUI and have breakpoints triggered in the server code, you might need to run `bun dev spawn` instead of
-  the usual `bun dev`. This is because `bun dev` runs the server in a worker thread and breakpoints might not work there.
-
-Other tips and tricks:
-
-- You might want to use `--inspect-wait` or `--inspect-brk` instead of `--inspect`, depending on your workflow
-- Specifying `--inspect=ws://localhost:6499/` on every invocation can be tiresome, you may want to `export BUN_OPTIONS=--inspect=ws://localhost:6499/` instead
-
-#### VSCode Setup
-
-If you use VSCode, you can use our example configurations [.vscode/settings.example.json](.vscode/settings.example.json) and [.vscode/launch.example.json](.vscode/launch.example.json).
-
-Some debug methods that can be problematic:
-
-- Debug configurations with `"request": "launch"` can have breakpoints incorrectly mapped and thus unusable
-- The same problem arises when running OpenCode in the VSCode `JavaScript Debug Terminal`
-
-With that said, you may want to try these methods, as they might work for you.
-
-## Pull Request Expectations
-
-- Try to keep pull requests small and focused.
-- Link relevant issue(s) in the description
-- Explain the issue and why your change fixes it
-- Avoid having verbose LLM generated PR descriptions
-- Before adding new functions or functionality, ensure that such behavior doesn't already exist elsewhere in the codebase.
-
-### Style Preferences
-
-These are not strictly enforced, they are just general guidelines:
-
-- **Functions:** Keep logic within a single function unless breaking it out adds clear reuse or composition benefits.
-- **Destructuring:** Do not do unnecessary destructuring of variables.
-- **Control flow:** Avoid `else` statements.
-- **Error handling:** Prefer `.catch(...)` instead of `try`/`catch` when possible.
-- **Types:** Reach for precise types and avoid `any`.
-- **Variables:** Stick to immutable patterns and avoid `let`.
-- **Naming:** Choose concise single-word identifiers when they remain descriptive.
-- **Runtime APIs:** Use Bun helpers such as `Bun.file()` when they fit the use case.
-
-## Feature Requests
-
-For net-new functionality, start with a design conversation. Open an issue describing the problem, your proposed approach (optional), and why it belongs in OpenCode. The core team will help decide whether it should move forward; please wait for that approval instead of opening a feature PR directly.

+## Installation
+
+### Using the Install Script
 
 ```bash
-# YOLO
+# Install the latest version
 curl -fsSL https://opencode.ai/install | bash
 
-# Package managers
-npm i -g opencode-ai@latest        # or bun/pnpm/yarn
-scoop bucket add extras; scoop install extras/opencode  # Windows
-choco install opencode             # Windows
-brew install opencode              # macOS and Linux
-paru -S opencode-bin               # Arch Linux
-mise use --pin -g ubi:sst/opencode # Any OS
-nix run nixpkgs#opencode           # or github:sst/opencode for latest dev branch
+# Install a specific version
+curl -fsSL https://opencode.ai/install | VERSION=0.1.0 bash
 ```
 
-> [!TIP]
-> Remove versions older than 0.1.x before installing.
-
-#### 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
+### Using Homebrew (macOS and Linux)
 
 ```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 install opencode-ai/tap/opencode
 ```
 
-### Agents
+### Using AUR (Arch Linux)
 
-OpenCode includes two built-in agents you can switch between,
-you can switch between these using the `Tab` key.
+```bash
+# Using yay
+yay -S opencode-bin
 
-- **build** - Default, full access agent for development work
-- **plan** - Read-only agent for analysis and code exploration
-  - Denies file edits by default
-  - Asks permission before running bash commands
-  - Ideal for exploring unfamiliar codebases or planning changes
+# Using paru
+paru -S opencode-bin
+```
 
-Also, included is a **general** subagent for complex searches and multi-step tasks.
-This is used internally and can be invoked using `@general` in messages.
+### Using Go
 
-Learn more about [agents](https://opencode.ai/docs/agents).
+```bash
+go install github.com/opencode-ai/opencode@latest
+```
 
-### Documentation
+## Configuration

-- 100% open source
-- Not coupled to any provider. Although we recommend the models we provide through [OpenCode Zen](https://opencode.ai/zen); OpenCode can be used with Claude, 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.
-- Out of the box LSP support
-- 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.
+## Supported AI Models
 
-#### What's the other repo?
+OpenCode supports a variety of AI models from different providers:

+
+## Architecture
+
+OpenCode is built with a modular architecture:
+
+- **cmd**: Command-line interface using Cobra
+- **internal/app**: Core application services
+- **internal/config**: Configuration management
+- **internal/db**: Database operations and migrations
+- **internal/llm**: LLM providers and tools integration
+- **internal/tui**: Terminal UI components and layouts
+- **internal/logging**: Logging infrastructure
+- **internal/message**: Message handling
+- **internal/session**: Session management
+- **internal/lsp**: Language Server Protocol integration
+
+## MCP (Model Context Protocol)
+
+OpenCode implements the Model Context Protocol (MCP) to extend its capabilities through external tools. MCP provides a standardized way for the AI assistant to interact with external services and tools.
+
+### MCP Features
+
+- **External Tool Integration**: Connect to external tools and services via a standardized protocol
+- **Tool Discovery**: Automatically discover available tools from MCP servers
+- **Multiple Connection Types**:
+  - **Stdio**: Communicate with tools via standard input/output
+  - **SSE**: Communicate with tools via Server-Sent Events
+- **Security**: Permission system for controlling access to MCP tools
+
+### Configuring MCP Servers
+
+MCP servers are defined in the configuration file under the `mcpServers` section:
+
+```json
+{
+  "mcpServers": {
+    "example": {
+      "type": "stdio",
+      "command": "path/to/mcp-server",
+      "env": [],
+      "args": []
+    },
+    "web-example": {
+      "type": "sse",
+      "url": "https://example.com/mcp",
+      "headers": {
+        "Authorization": "Bearer token"
+      }
+    }
+  }
+}
+```
+
+### MCP Tool Usage
+
+Once configured, MCP tools are automatically available to the AI assistant alongside built-in tools. They follow the same permission model as other tools, requiring user approval before execution.
+
+## LSP (Language Server Protocol)
+
+OpenCode integrates with Language Server Protocol to provide code intelligence features across multiple programming languages.
+
+### LSP Features
+
+- **Multi-language Support**: Connect to language servers for different programming languages
+- **Diagnostics**: Receive error checking and linting information
+- **File Watching**: Automatically notify language servers of file changes
+
+### Configuring LSP
+
+Language servers are configured in the configuration file under the `lsp` section:
+
+```json
+{
+  "lsp": {
+    "go": {
+      "disabled": false,
+      "command": "gopls"
+    },
+    "typescript": {
+      "disabled": false,
+      "command": "typescript-language-server",
+      "args": ["--stdio"]
+    }
+  }
+}
+```
+
+### LSP Integration with AI
+
+The AI assistant can access LSP features through the `diagnostics` tool, allowing it to:
+
+- Check for errors in your code
+- Suggest fixes based on diagnostics
+
+While the LSP client implementation supports the full LSP protocol (including completions, hover, definition, etc.), currently only diagnostics are exposed to the AI assistant.
+
+## Development
+
+### Prerequisites

+# OpenCode Configuration Schema Generator
+
+This tool generates a JSON Schema for the OpenCode configuration file. The schema can be used to validate configuration files and provide autocompletion in editors that support JSON Schema.
+
+## Usage
+
+```bash
+go run cmd/schema/main.go > opencode-schema.json
+```
+
+This will generate a JSON Schema file that can be used to validate configuration files.
+
+## Schema Features
+
+The generated schema includes:
+
+- All configuration options with descriptions
+- Default values where applicable
+- Validation for enum values (e.g., model IDs, provider types)
+- Required fields
+- Type checking
+
+## Using the Schema
+
+You can use the generated schema in several ways:
+
+1. **Editor Integration**: Many editors (VS Code, JetBrains IDEs, etc.) support JSON Schema for validation and autocompletion. You can configure your editor to use the generated schema for `.opencode.json` files.
+
+2. **Validation Tools**: You can use tools like [jsonschema](https://github.com/Julian/jsonschema) to validate your configuration files against the schema.
+
+3. **Documentation**: The schema serves as documentation for the configuration options.
+
+## Example Configuration
+
+Here's an example configuration that conforms to the schema:
+
+```json
+{
+  "data": {
+    "directory": ".opencode"
+  },
+  "debug": false,
+  "providers": {
+    "anthropic": {
+      "apiKey": "your-api-key"
+    }
+  },
+  "agents": {
+    "coder": {
+      "model": "claude-3.7-sonnet",
+      "maxTokens": 5000,
+      "reasoningEffort": "medium"
+    },
+    "task": {
+      "model": "claude-3.7-sonnet",
+      "maxTokens": 5000

+      "model": "claude-3.7-sonnet",
+      "maxTokens": 80

-## 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 \
-     MOCK_TOKEN=github_pat_1234567890 \
-     MOCK_EVENT='{"eventName":"issue_comment",...}' \
-     bun /path/to/opencode/github/index.ts
-   ```
-
-   - `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.
-   - `MOCK_TOKEN`: A GitHub personal 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).
-   - `MOCK_EVENT`: Mock GitHub event payload (see templates below).
-   - `/path/to/opencode`: Path to your cloned opencode repo. `bun /path/to/opencode/github/index.ts` runs your local version of `opencode`.
-
-### Issue comment event
-
-```
-MOCK_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 commenter
-- `"number":4` with the GitHub issue id
-- `"body":"hey opencode, summarize thread"` with comment body
-
-### Issue comment with image attachment.
-
-```
-MOCK_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
-
-```
-MOCK_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"}}}'

When you are searching for a keyword or file and are not confident that you will find the right match on the first try, use the Agent tool to perform the search for you. For example:\n\n- If you are searching for a keyword like \"config\" or \"logger\", or for questions like \"which file does X?\", the Agent tool is strongly recommended\n- If you want to read a specific file path, use the View or GlobTool tool instead of the Agent tool, to find the match more quickly\n- If you are searching for a specific class definition like \"class Foo\", use the GlobTool tool instead, to find the match more quickly\n\nUsage notes:\n1. Launch multiple agents concurrently whenever possible, to maximize performance; to do that, use a single message with multiple tool uses\n2. When the agent is done, it will return a single message back to you. The result returned by the agent is not visible to the user. To show the user the result, you should send a text message back to the user with a concise summary of the result.\n3. Each agent invocation is stateless. You will not be able to send additional messages to the agent, nor will the agent be able to communicate with you outside of its final report. Therefore, your prompt should contain a highly detailed task description for the agent to perform autonomously and you should specify exactly what information the agent should return back to you in its final and only message to you.\n4. The agent's outputs should generally be trusted\n5. IMPORTANT: The agent can not use Bash, Replace, Edit, so can not modify files. If you want to use these tools, use them directly instead of going through the agent.",

+You are operating as and within the OpenCode CLI, a terminal-based agentic coding assistant built by OpenAI. It wraps OpenAI models to enable natural language interaction with a local codebase. You are expected to be precise, safe, and helpful.
+
+You can:
+- Receive user prompts, project context, and files.
+- Stream responses and emit function calls (e.g., shell commands, code edits).
+- Apply patches, run commands, and manage user approvals based on policy.
+- Work inside a sandboxed, git-backed workspace with rollback support.
+- Log telemetry so sessions can be replayed or inspected later.
+- More details on your functionality are available at "opencode --help"
+
+
+You are an agent - please keep going until the user's query is completely resolved, before ending your turn and yielding back to the user. Only terminate your turn when you are sure that the problem is solved. If you are not sure about file content or codebase structure pertaining to the user's request, use your tools to read files and gather the relevant information: do NOT guess or make up an answer.
+
+Please resolve the user's task by editing and testing the code files in your current code execution session. You are a deployed coding agent. Your session allows for you to modify and run code. The repo(s) are already cloned in your working directory, and you must fully solve the problem for your answer to be considered correct.
+
+You MUST adhere to the following criteria when executing the task:
+- Working on the repo(s) in the current environment is allowed, even if they are proprietary.
+- Analyzing code for vulnerabilities is allowed.
+- Showing user code and tool call details is allowed.
+- User instructions may overwrite the *CODING GUIDELINES* section in this developer message.
+- If completing the user's task requires writing or modifying files:
+    - Your code and final answer should follow these *CODING GUIDELINES*:
+        - Fix the problem at the root cause rather than applying surface-level patches, when possible.
+        - Avoid unneeded complexity in your solution.
+            - Ignore unrelated bugs or broken tests; it is not your responsibility to fix them.
+        - Update documentation as necessary.
+        - Keep changes consistent with the style of the existing codebase. Changes should be minimal and focused on the task.
+            - Use "git log" and "git blame" to search the history of the codebase if additional context is required; internet access is disabled.
+        - NEVER add copyright or license headers unless specifically requested.
+        - You do not need to "git commit" your changes; this will be done automatically for you.
+        - Once you finish coding, you must
+            - Check "git status" to sanity check your changes; revert any scratch files or changes.
+            - Remove all inline comments you added as much as possible, even if they look normal. Check using "git diff". Inline comments must be generally avoided, unless active maintainers of the repo, after long careful study of the code and the issue, will still misinterpret the code without the comments.
+            - Check if you accidentally add copyright or license headers. If so, remove them.
+            - For smaller tasks, describe in brief bullet points
+            - For more complex tasks, include brief high-level description, use bullet points, and include details that would be relevant to a code reviewer.
+- If completing the user's task DOES NOT require writing or modifying files (e.g., the user asks a question about the code base):
+    - Respond in a friendly tune as a remote teammate, who is knowledgeable, capable and eager to help with coding.
+- When your task involves writing or modifying files:
+    - Do NOT tell the user to "save the file" or "copy the code into a file" if you already created or modified the file using "apply_patch". Instead, reference the file as already saved.
+    - Do NOT show the full contents of large files you have already written, unless the user explicitly asks for them.
+- When doing things with paths, always use use the full path, if the working directory is /abc/xyz  and you want to edit the file abc.go in the working dir refer to it as /abc/xyz/abc.go.
+- If you send a path not including the working dir, the working dir will be prepended to it.

+
+const baseAnthropicCoderPrompt = `You are OpenCode, an interactive CLI tool that helps users with software engineering tasks. Use the instructions below and the tools available to you to assist the user.
+
+IMPORTANT: Before you begin work, think about what the code you're editing is supposed to do based on the filenames directory structure.
+
+# Memory
+If the current working directory contains a file called OpenCode.md, it will be automatically added to your context. This file serves multiple purposes:
+1. Storing frequently used bash commands (build, test, lint, etc.) so you can use them without searching each time
+2. Recording the user's code style preferences (naming conventions, preferred libraries, etc.)
+3. Maintaining useful information about the codebase structure and organization
+
+When you spend time searching for commands to typecheck, lint, build, or test, you should ask the user if it's okay to add those commands to OpenCode.md. Similarly, when learning about code style preferences or important codebase information, ask if it's okay to add that to OpenCode.md so you can remember it for next time.
+
+# Tone and style
+You should be concise, direct, and to the point. When you run a non-trivial bash command, you should explain what the command does and why you are running it, to make sure the user understands what you are doing (this is especially important when you are running a command that will make changes to the user's system).
+Remember that your output will be displayed on a command line interface. Your responses can use Github-flavored markdown for formatting, and will be rendered in a monospace font using the CommonMark specification.
+Output text to communicate with the user; all text you output outside of tool use is displayed to the user. Only use tools to complete tasks. Never use tools like Bash or code comments as means to communicate with the user during the session.
+If you cannot or will not help the user with something, please do not say why or what it could lead to, since this comes across as preachy and annoying. Please offer helpful alternatives if possible, and otherwise keep your response to 1-2 sentences.
+IMPORTANT: You should minimize output tokens as much as possible while maintaining helpfulness, quality, and accuracy. Only address the specific query or task at hand, avoiding tangential information unless absolutely critical for completing the request. If you can answer in 1-3 sentences or a short paragraph, please do.
+IMPORTANT: You should NOT answer with unnecessary preamble or postamble (such as explaining your code or summarizing your action), unless the user asks you to.
+IMPORTANT: Keep your responses short, since they will be displayed on a command line interface. You MUST answer concisely with fewer than 4 lines (not including tool use or code generation), unless user asks for detail. Answer the user's question directly, without elaboration, explanation, or details. One word answers are best. Avoid introductions, conclusions, and explanations. You MUST avoid text before/after your response, such as "The answer is <answer>.", "Here is the content of the file..." or "Based on the information provided, the answer is..." or "Here is what I will do next...". Here are some examples to demonstrate appropriate verbosity:
+<example>
+user: 2 + 2
+assistant: 4
+</example>
+
+<example>
+user: what is 2+2?
+assistant: 4
+</example>
+
+<example>
+user: is 11 a prime number?
+assistant: true
+</example>
+
+<example>
+user: what command should I run to list files in the current directory?
+assistant: ls
+</example>
+
+<example>
+user: what command should I run to watch files in the current directory?
+assistant: [use the ls tool to list the files in the current directory, then read docs/commands in the relevant file to find out how to watch files]
+npm run dev
+</example>
+
+<example>
+user: How many golf balls fit inside a jetta?
+assistant: 150000
+</example>
+
+<example>
+user: what files are in the directory src/?
+assistant: [runs ls and sees foo.c, bar.c, baz.c]
+user: which file contains the implementation of foo?
+assistant: src/foo.c
+</example>
+
+<example>
+user: write tests for new feature
+assistant: [uses grep and glob search tools to find where similar tests are defined, uses concurrent read file tool use blocks in one tool call to read relevant files at the same time, uses edit/patch file tool to write new tests]
+</example>
+
+# Proactiveness
+You are allowed to be proactive, but only when the user asks you to do something. You should strive to strike a balance between:
+1. Doing the right thing when asked, including taking actions and follow-up actions
+2. Not surprising the user with actions you take without asking
+For example, if the user asks you how to approach something, you should do your best to answer their question first, and not immediately jump into taking actions.
+3. Do not add additional code explanation summary unless requested by the user. After working on a file, just stop, rather than providing an explanation of what you did.
+
+# Following conventions
+When making changes to files, first understand the file's code conventions. Mimic code style, use existing libraries and utilities, and follow existing patterns.
+- NEVER assume that a given library is available, even if it is well known. Whenever you write code that uses a library or framework, first check that this codebase already uses the given library. For example, you might look at neighboring files, or check the package.json (or cargo.toml, and so on depending on the language).
+- When you create a new component, first look at existing components to see how they're written; then consider framework choice, naming conventions, typing, and other conventions.
+- When you edit a piece of code, first look at the code's surrounding context (especially its imports) to understand the code's choice of frameworks and libraries. Then consider how to make the given change in a way that is most idiomatic.
+- Always follow security best practices. Never introduce code that exposes or logs secrets and keys. Never commit secrets or keys to the repository.
+
+# Code style
+- Do not add comments to the code you write, unless the user asks you to, or the code is complex and requires additional context.
+
+# Doing tasks
+The user will primarily request you perform software engineering tasks. This includes solving bugs, adding new functionality, refactoring code, explaining code, and more. For these tasks the following steps are recommended:
+1. Use the available search tools to understand the codebase and the user's query. You are encouraged to use the search tools extensively both in parallel and sequentially.
+2. Implement the solution using all tools available to you
+3. Verify the solution if possible with tests. NEVER assume specific test framework or test script. Check the README or search codebase to determine the testing approach.
+4. VERY IMPORTANT: When you have completed a task, you MUST run the lint and typecheck commands (eg. npm run lint, npm run typecheck, ruff, etc.) if they were provided to you to ensure your code is correct. If you are unable to find the correct command, ask the user for the command to run and if they supply it, proactively suggest writing it to opencode.md so that you will know to run it next time.
+
+NEVER commit changes unless the user explicitly asks you to. It is VERY IMPORTANT to only commit when explicitly asked, otherwise the user will feel that you are being too proactive.
+
+# Tool usage policy
+- When doing file search, prefer to use the Agent tool in order to reduce context usage.
+- If you intend to call multiple tools and there are no dependencies between the calls, make all of the independent calls in the same function_calls block.
+- IMPORTANT: The user does not see the full output of the tool responses, so if you need the output of the tool for the response make sure to summarize it for the user.
+
+You MUST answer concisely with fewer than 4 lines of text (not including tool use or code generation), unless user asks for detail.`
