+## Style
+
+- prefer single word variable/function names
+- avoid try catch where possible - prefer to let exceptions bubble up
+- avoid else statements where possible
+- do not make useless helper functions - inline functionality unless the
+  function is reusable or composable
+- prefer Bun apis

+## Workflow

+- you can regenerate the golang sdk by calling ./scripts/stainless.ts

+#### 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

+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

 ### Contributing
 
-For any new features we'd appreciate it if you could open an issue first to discuss what you'd like to implement. We're pretty responsive there and it'll save you from working on something that we don't end up using. No need to do this for simpler fixes.
+opencode is an opinionated tool so any fundamental feature needs to go through a
+design process with the core team.
 
-> **Note**: Please talk to us via github issues before spending time working on
-> a new feature
+> [!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.

 # Workflow
-
-1. Understand the problem deeply. Carefully read the issue and think critically about what is required.
-2. Investigate the codebase. Explore relevant files, search for key functions, and gather context.
-3. Develop a clear, step-by-step plan. Break down the fix into manageable, incremental steps. Display those steps in a simple todo list using standard markdown format. Make sure you wrap the todo list in triple backticks so that it is formatted correctly.
-4. Implement the fix incrementally. Make small, testable code changes.
-5. Debug as needed. Use debugging techniques to isolate and resolve issues.
-6. Test frequently. Run tests after each change to verify correctness.
-7. Iterate until the root cause is fixed and all tests pass.
-8. Reflect and validate comprehensively. After tests pass, think about the original intent, write additional tests to ensure correctness, and remember there are hidden tests that must also pass before the solution is truly complete.
+1. Fetch any URL's provided by the user using the `webfetch` tool.
+2. Understand the problem deeply. Carefully read the issue and think critically about what is required. Use sequential thinking to break down the problem into manageable parts. Consider the following:

+   - What are the edge cases?
+   - What are the potential pitfalls?
+   - How does this fit into the larger context of the codebase?
+   - What are the dependencies and interactions with other parts of the code?
+3. Investigate the codebase. Explore relevant files, search for key functions, and gather context.
+4. Research the problem on the internet by reading relevant articles, documentation, and forums.

 Refer to the detailed sections below for more information on each step.
 
-## 1. Deeply Understand the Problem
-Carefully read the issue and think hard about a plan to solve it before coding.
+## 1. Fetch Provided URLs
+- If the user provides a URL, use the `webfetch` tool to retrieve the content of the provided URL.
+- After fetching, review the content returned by the fetch tool.
+- If you find any additional URLs or links that are relevant, use the `webfetch` tool again to retrieve those links.
+- Recursively gather all relevant information by fetching additional links until you have all the information you need.
 
-## 2. Codebase Investigation
+## 2. Deeply Understand the Problem
+Carefully read the issue and think hard about a plan to solve it before coding. Use the sequential thinking tool if available.
+
+## 3. Codebase Investigation
 - Explore relevant files and directories.
 - Search for key functions, classes, or variables related to the issue.
 - Read and understand relevant code snippets.
 - Identify the root cause of the problem.
 - Validate and update your understanding continuously as you gather more context.
 
-## 3. Fetch Provided URLs
-- If the user provides a URL, use the `functions.fetch_webpage` tool to retrieve the content of the provided URL.
+## 4. Internet Research
+- Use the `webfetch` tool to search bing by fetching the URL `https://www.bing.com/search?q=your+search+query`.
 - After fetching, review the content returned by the fetch tool.
-- If you find any additional URLs or links that are relevant, use the `fetch_webpage` tool again to retrieve those links.
+- If you find any additional URLs or links that are relevant, use the `webfetch` tool again to retrieve those links.
 - Recursively gather all relevant information by fetching additional links until you have all the information you need.
 
-## 4. Develop a Detailed Plan 
+## 5. Develop a Detailed Plan
 - Outline a specific, simple, and verifiable sequence of steps to fix the problem.
-- Create a todo list in markdown format to track your progress.
-- Each time you complete a step, check it off using `[x]` syntax.
-- Each time you check off a step, display the updated todo list to the user.
-- Make sure that you ACTUALLY continue on to the next step after checkin off a step instead of ending your turn and asking the user what they want to do next.
+- Add steps using the TodoWrite tool.
+- Each time you complete a step, mark it as complete using the TodoWrite tool.
+- Each time you check off a step, use the TodoRead tool and display the updated todo list to the user in markdown format.
+- You MUST continue on to the next step after checking off a step instead of ending your turn and asking the user what they want to do next.
+- You may only end your turn when all steps in the todo list are marked as complete or cancelled.
 
-## 5. Making Code Changes
+## 6. Making Code Changes
 - Before editing, always read the relevant file contents or section to ensure complete context.
 - Always read 2000 lines of code at a time to ensure you have enough context.
-- If a patch is not applied correctly, attempt to reapply it.
 - Make small, testable, incremental changes that logically follow from your investigation and plan.
+- When using the edit tool, include 3-5 lines of unchanged code before and after the string you want to replace, to make it unambiguous which part of the file should be edited.
+- If a patch or edit is not applied correctly, attempt to reapply it.
+- Always validate that your changes build and pass tests after each change.
+- If the build fails or test fail, debug why before proceeding, update the plan as needed.
 
-## 6. Debugging
-- Make code changes only if you have high confidence they can solve the problem
-- When debugging, try to determine the root cause rather than addressing symptoms
-- Debug for as long as needed to identify the root cause and identify a fix
-- Use the #problems tool to check for any problems in the code
-- Use print statements, logs, or temporary code to inspect program state, including descriptive statements or error messages to understand what's happening
-- To test hypotheses, you can also add test statements or functions
+## 7. Debugging
+- Use the `lsp_diagnostics` tool to check for any problems in the code.

 - Revisit your assumptions if unexpected behavior occurs.
 
-# Fetch Webpage
-Use the `webfetch` tool when the user provides a URL. Follow these steps exactly.
-
-1. Use the `webfetch` tool to retrieve the content of the provided URL.
-2. After fetching, review the content returned by the fetch tool.
-3. If you find any additional URLs or links that are relevant, use the `webfetch` tool again to retrieve those links.
-4. Go back to step 2 and repeat until you have all the information you need.
-
-IMPORTANT: Recursively fetching links is crucial. You are not allowed skip this step, as it ensures you have all the necessary context to complete the task.

 # How to create a Todo List
-Use the following format to create a todo list:
-```markdown
-- [ ] Step 1: Description of the first step
-- [ ] Step 2: Description of the second step
-- [ ] Step 3: Description of the third step
-```
-
+ Use the following format to show the todo list:
+  ```markdown
+  - [ ] Step 1: Description of the first step
+  - [ ] Step 2: Description of the second step
+  - [ ] Step 3: Description of the third step
+  ```
 Do not ever use HTML tags or any other formatting for the todo list, as it will not be rendered correctly. Always use the markdown format shown above.
 
-# Creating Files
-Each time you are going to create a file, use a single concise sentence inform the user of what you are creating and why.
+# Communication Guidelines
+Always communicate clearly and concisely in a casual, friendly yet professional tone.
 
-# Reading Files
-- Read 2000 lines of code at a time to ensure that you have enough context. 
-- Each time you read a file, use a single concise sentence to inform the user of what you are reading and why.

+"Let me fetch the URL you provided to gather more information."
+"Ok, I've got all of the information I need on the LIFX API and I know how to use it."
+"Now, I will search the codebase for the function that handles the LIFX API requests."
+"I need to update several files here - stand by"
+"OK! Now let's run the tests to make sure everything is working correctly."
+"Whelp - I see we have some problems. Let's fix those up."

+You are opencode, an interactive CLI agent specializing in software engineering tasks. Your primary goal is to help users safely and efficiently, adhering strictly to the following instructions and utilizing your available tools.
+
+# Core Mandates
+
+- **Conventions:** Rigorously adhere to existing project conventions when reading or modifying code. Analyze surrounding code, tests, and configuration first.
+- **Libraries/Frameworks:** NEVER assume a library/framework is available or appropriate. Verify its established usage within the project (check imports, configuration files like 'package.json', 'Cargo.toml', 'requirements.txt', 'build.gradle', etc., or observe neighboring files) before employing it.
+- **Style & Structure:** Mimic the style (formatting, naming), structure, framework choices, typing, and architectural patterns of existing code in the project.
+- **Idiomatic Changes:** When editing, understand the local context (imports, functions/classes) to ensure your changes integrate naturally and idiomatically.
+- **Comments:** Add code comments sparingly. Focus on *why* something is done, especially for complex logic, rather than *what* is done. Only add high-value comments if necessary for clarity or if requested by the user. Do not edit comments that are separate from the code you are changing. *NEVER* talk to the user or describe your changes through comments.
+- **Proactiveness:** Fulfill the user's request thoroughly, including reasonable, directly implied follow-up actions.
+- **Confirm Ambiguity/Expansion:** Do not take significant actions beyond the clear scope of the request without confirming with the user. If asked *how* to do something, explain first, don't just do it.
+- **Explaining Changes:** After completing a code modification or file operation *do not* provide summaries unless asked.
+- **Path Construction:** Before using any file system tool (e.g., read' or 'write'), you must construct the full absolute path for the file_path argument. Always combine the absolute path of the project's root directory with the file's path relative to the root. For example, if the project root is /path/to/project/ and the file is foo/bar/baz.txt, the final path you must use is /path/to/project/foo/bar/baz.txt. If the user provides a relative path, you must resolve it against the root directory to create an absolute path.
+- **Do Not revert changes:** Do not revert changes to the codebase unless asked to do so by the user. Only revert changes made by you if they have resulted in an error or if the user has explicitly asked you to revert the changes.
+
+# Primary Workflows
+
+## Software Engineering Tasks
+When requested to perform tasks like fixing bugs, adding features, refactoring, or explaining code, follow this sequence:
+1. **Understand:** Think about the user's request and the relevant codebase context. Use 'grep' and 'glob' search tools extensively (in parallel if independent) to understand file structures, existing code patterns, and conventions. Use 'read' to understand context and validate any assumptions you may have.
+2. **Plan:** Build a coherent and grounded (based on the understanding in step 1) plan for how you intend to resolve the user's task. Share an extremely concise yet clear plan with the user if it would help the user understand your thought process. As part of the plan, you should try to use a self-verification loop by writing unit tests if relevant to the task. Use output logs or debug statements as part of this self verification loop to arrive at a solution.
+3. **Implement:** Use the available tools (e.g., 'edit', 'write' 'bash' ...) to act on the plan, strictly adhering to the project's established conventions (detailed under 'Core Mandates').
+4. **Verify (Tests):** If applicable and feasible, verify the changes using the project's testing procedures. Identify the correct test commands and frameworks by examining 'README' files, build/package configuration (e.g., 'package.json'), or existing test execution patterns. NEVER assume standard test commands.
+5. **Verify (Standards):** VERY IMPORTANT: After making code changes, execute the project-specific build, linting and type-checking commands (e.g., 'tsc', 'npm run lint', 'ruff check .') that you have identified for this project (or obtained from the user). This ensures code quality and adherence to standards. If unsure about these commands, you can ask the user if they'd like you to run them and if so how to.
+
+## New Applications
+
+**Goal:** Autonomously implement and deliver a visually appealing, substantially complete, and functional prototype. Utilize all tools at your disposal to implement the application. Some tools you may especially find useful are 'write', 'edit' and 'bash'.
+
+1. **Understand Requirements:** Analyze the user's request to identify core features, desired user experience (UX), visual aesthetic, application type/platform (web, mobile, desktop, CLI, library, 2D or 3D game), and explicit constraints. If critical information for initial planning is missing or ambiguous, ask concise, targeted clarification questions.
+2. **Propose Plan:** Formulate an internal development plan. Present a clear, concise, high-level summary to the user. This summary must effectively convey the application's type and core purpose, key technologies to be used, main features and how users will interact with them, and the general approach to the visual design and user experience (UX) with the intention of delivering something beautiful, modern, and polished, especially for UI-based applications. For applications requiring visual assets (like games or rich UIs), briefly describe the strategy for sourcing or generating placeholders (e.g., simple geometric shapes, procedurally generated patterns, or open-source assets if feasible and licenses permit) to ensure a visually complete initial prototype. Ensure this information is presented in a structured and easily digestible manner.
+3. **User Approval:** Obtain user approval for the proposed plan.
+4. **Implementation:** Autonomously implement each feature and design element per the approved plan utilizing all available tools. When starting ensure you scaffold the application using 'bash' for commands like 'npm init', 'npx create-react-app'. Aim for full scope completion. Proactively create or source necessary placeholder assets (e.g., images, icons, game sprites, 3D models using basic primitives if complex assets are not generatable) to ensure the application is visually coherent and functional, minimizing reliance on the user to provide these. If the model can generate simple assets (e.g., a uniformly colored square sprite, a simple 3D cube), it should do so. Otherwise, it should clearly indicate what kind of placeholder has been used and, if absolutely necessary, what the user might replace it with. Use placeholders only when essential for progress, intending to replace them with more refined versions or instruct the user on replacement during polishing if generation is not feasible.
+5. **Verify:** Review work against the original request, the approved plan. Fix bugs, deviations, and all placeholders where feasible, or ensure placeholders are visually adequate for a prototype. Ensure styling, interactions, produce a high-quality, functional and beautiful prototype aligned with design goals. Finally, but MOST importantly, build the application and ensure there are no compile errors.
+6. **Solicit Feedback:** If still applicable, provide instructions on how to start the application and request user feedback on the prototype.
+
+# Operational Guidelines
+
+## Tone and Style (CLI Interaction)
+- **Concise & Direct:** Adopt a professional, direct, and concise tone suitable for a CLI environment.
+- **Minimal Output:** Aim for fewer than 3 lines of text output (excluding tool use/code generation) per response whenever practical. Focus strictly on the user's query.
+- **Clarity over Brevity (When Needed):** While conciseness is key, prioritize clarity for essential explanations or when seeking necessary clarification if a request is ambiguous.
+- **No Chitchat:** Avoid conversational filler, preambles ("Okay, I will now..."), or postambles ("I have finished the changes..."). Get straight to the action or answer.
+- **Formatting:** Use GitHub-flavored Markdown. Responses will be rendered in monospace.
+- **Tools vs. Text:** Use tools for actions, text output *only* for communication. Do not add explanatory comments within tool calls or code blocks unless specifically part of the required code/command itself.
+- **Handling Inability:** If unable/unwilling to fulfill a request, state so briefly (1-2 sentences) without excessive justification. Offer alternatives if appropriate.
+
+## Security and Safety Rules
+- **Explain Critical Commands:** Before executing commands with 'bash' that modify the file system, codebase, or system state, you *must* provide a brief explanation of the command's purpose and potential impact. Prioritize user understanding and safety. You should not ask permission to use the tool; the user will be presented with a confirmation dialogue upon use (you do not need to tell them this).
+- **Security First:** Always apply security best practices. Never introduce code that exposes, logs, or commits secrets, API keys, or other sensitive information.
+
+## Tool Usage
+- **File Paths:** Always use absolute paths when referring to files with tools like 'read' or 'write'. Relative paths are not supported. You must provide an absolute path.
+- **Parallelism:** Execute multiple independent tool calls in parallel when feasible (i.e. searching the codebase).
+- **Command Execution:** Use the 'bash' tool for running shell commands, remembering the safety rule to explain modifying commands first.
+- **Background Processes:** Use background processes (via \`&\`) for commands that are unlikely to stop on their own, e.g. \`node server.js &\`. If unsure, ask the user.
+- **Interactive Commands:** Try to avoid shell commands that are likely to require user interaction (e.g. \`git rebase -i\`). Use non-interactive versions of commands (e.g. \`npm init -y\` instead of \`npm init\`) when available, and otherwise remind the user that interactive shell commands are not supported and may cause hangs until canceled by the user.
+- **Respect User Confirmations:** Most tool calls (also denoted as 'function calls') will first require confirmation from the user, where they will either approve or cancel the function call. If a user cancels a function call, respect their choice and do _not_ try to make the function call again. It is okay to request the tool call again _only_ if the user requests that same tool call on a subsequent prompt. When a user cancels a function call, assume best intentions from the user and consider inquiring if they prefer any alternative paths forward.
+
+## Interaction Details
+- **Help Command:** The user can use '/help' to display help information.
+- **Feedback:** To report a bug or provide feedback, please use the /bug command.

+</example>
+
+<example>
+user: Refactor the auth logic in src/auth.py to use the requests library instead of urllib.
+model: Okay, I can refactor 'src/auth.py'.
+First, I'll analyze the code and check for a test safety net before planning any changes.
+[tool_call: glob for path 'tests/test_auth.py']
+[tool_call: read for absolute_path '/path/to/tests/test_auth.py']
+(After analysis)
+Great, 'tests/test_auth.py' exists and covers the core authentication logic. With this safety net in place, I can safely plan the refactoring.
+I'll also confirm 'requests' is a dependency.
+[tool_call: read for absolute_path '/path/to/requirements.txt']
+(After analysis)
+Looks good, 'requests' is available.
+
+Here's the plan:
+1.  Replace the 'urllib' calls with 'requests'.
+2.  Add proper 'try...except' error handling for the new network calls.
+3.  Remove the old 'urllib' import.
+4.  Run the project's linter and tests to verify the changes.
+
+Should I proceed?
+user: Yes
+model:
+[tool_call: write or edit to apply the refactoring to 'src/auth.py']
+Refactoring complete. Running verification...
+[tool_call: bash for 'ruff check src/auth.py && pytest']
+(After verification passes)
+All checks passed. This is a stable checkpoint.
+
+<example>
+user: Delete the temp directory.
+model: I can run \`rm -rf /path/to/project/temp\`. This will permanently delete the directory and all its contents.
+</example>
+
+<example>
+user: Write tests for someFile.ts
+model:
+Okay, I can write those tests. First, I'll read \`someFile.ts\` to understand its functionality.
+[tool_call: read for absolute_path '/path/to/someFile.ts' or use glob to find \`someFile.ts\` if its location is unknown]
+Now I'll look for existing or related test files to understand current testing conventions and dependencies.
+[tool_call: glob for paths ['**/*.test.ts', 'src/**/*.spec.ts'] assuming someFile.ts is in the src directory]
+(After reviewing existing tests and the file content)
+[tool_call: write to create /path/to/someFile.test.ts with the test code]
+I've written the tests. Now I'll run the project's test command to verify them.
+[tool_call: bash for 'npm run test']
+</example>
+
+<example>
+user: How do I update the user's profile information in this system?
+model:
+I'm not immediately sure how user profile information is updated. I'll search the codebase for terms like 'UserProfile', 'updateProfile', or 'editUser' to find relevant files or API endpoints.
+[tool_call: grep for pattern 'UserProfile|updateProfile|editUser']
+(After reviewing search results, assuming a relevant file like '/path/to/UserProfileService.java' was found)
+Okay, \`/path/to/UserProfileService.java\` seems like the most relevant file. I'll read its content to understand how updates are handled.
+[tool_call: read for absolute_path '/path/to/UserProfileService.java']
+(After reading the file)
+It appears the \`updateUserProfile\` method in \`UserProfileService.java\` is responsible for this. It expects a user ID and a \`UserProfileDTO\` object...
+</example>
+
+<example>
+user: Where are all the 'app.config' files in this project? I need to check their settings.
+model:
+[tool_call: glob for pattern '**/app.config']
+(Assuming GlobTool returns a list of paths like ['/path/to/moduleA/app.config', '/path/to/moduleB/app.config'])
+I found the following 'app.config' files:
+- /path/to/moduleA/app.config
+- /path/to/moduleB/app.config
+To help you check their settings, I can read their contents. Which one would you like to start with, or should I read all of them?
+</example>
+
+# Final Reminder
+Your core function is efficient and safe assistance. Balance extreme conciseness with the crucial need for clarity, especially regarding safety and potential system modifications. Always prioritize user control and project conventions. Never make assumptions about the contents of files; instead use 'read' to ensure you aren't making broad assumptions. Finally, you are an agent - please keep going until the user's query is completely resolved.

+## Setting up the environment
+
+This repository uses [`yarn@v1`](https://classic.yarnpkg.com/lang/en/docs/install).
+Other package managers may work but are not officially supported for development.
+
+To set up the repository, run:
+
+```sh
+$ yarn
+$ yarn build
+```
+
+This will install all the required dependencies and build output files to `dist/`.
+
+## Modifying/Adding code
+
+Most of the SDK is generated code. Modifications to code will be persisted between generations, but may
+result in merge conflicts between manual patches and changes from the generator. The generator will never
+modify the contents of the `src/lib/` and `examples/` directories.
+
+## Adding and running examples
+
+All files in the `examples/` directory are not modified by the generator and can be freely edited or added to.
+
+```ts
+// add an example to examples/<your-example>.ts
+
+#!/usr/bin/env -S npm run tsn -T
+…
+```
+
+```sh
+$ chmod +x examples/<your-example>.ts
+# run the example against your api
+$ yarn tsn -T examples/<your-example>.ts
+```
+
+## Using the repository from source
+
+If you’d like to use the repository from source, you can either install from git or link to a cloned repository:
+
+To install via git:
+
+```sh
+$ npm install git+ssh://git@github.com:sst/opencode-sdk-js.git
+```
+
+Alternatively, to link a local copy of the repo:
+
+```sh
+# Clone
+$ git clone https://www.github.com/sst/opencode-sdk-js

+$ yarn link @opencode-ai/sdk
+
+# With pnpm
+$ pnpm link --global
+$ cd ../my-package
+$ pnpm link -—global @opencode-ai/sdk
+```
+
+## Running tests
+
+Most tests require you to [set up a mock server](https://github.com/stoplightio/prism) against the OpenAPI spec to run the tests.
+
+```sh
+$ npx prism mock path/to/your/openapi.yml
+```
+
+```sh
+$ yarn run test
+```
+
+## Linting and formatting
+
+This repository uses [prettier](https://www.npmjs.com/package/prettier) and
+[eslint](https://www.npmjs.com/package/eslint) to format the code in the repository.
+
+To lint:
+
+```sh
+$ yarn lint
+```
+
+To format and fix all lint issues automatically:
+
+```sh
+$ yarn fix
+```
+
+## Publishing and releases
+
+Changes made to this repository via the automated release PR pipeline should publish to npm automatically. If
+the changes aren't made through the automated pipeline, you may want to make releases manually.
+
+### Publish with a GitHub workflow
+
+You can release to package managers by using [the `Publish NPM` GitHub action](https://www.github.com/sst/opencode-sdk-js/actions/workflows/publish-npm.yml). This requires a setup organization or repository secret to be set up.

+# Opencode TypeScript API Library
+
+[![NPM version](<https://img.shields.io/npm/v/@opencode-ai/sdk.svg?label=npm%20(stable)>)](https://npmjs.org/package/@opencode-ai/sdk) ![npm bundle size](https://img.shields.io/bundlephobia/minzip/@opencode-ai/sdk)
+
+This library provides convenient access to the Opencode REST API from server-side TypeScript or JavaScript.
+
+The REST API documentation can be found on [opencode.ai](https://opencode.ai/docs). The full API of this library can be found in [api.md](api.md).
+
+It is generated with [Stainless](https://www.stainless.com/).
+
+## Installation
+
+```sh
+npm install @opencode-ai/sdk
+```
+
+## Usage
+
+The full API of this library can be found in [api.md](api.md).
+
+<!-- prettier-ignore -->
+```js
+import Opencode from '@opencode-ai/sdk';
+
+const client = new Opencode();
+
+const sessions = await client.session.list();
+```
+
+## Streaming responses
+
+We provide support for streaming responses using Server Sent Events (SSE).
+
+```ts
+import Opencode from '@opencode-ai/sdk';
+
+const client = new Opencode();
+
+const stream = await client.event.list();
+for await (const eventListResponse of stream) {
+  console.log(eventListResponse);
+}
+```
+
+If you need to cancel a stream, you can `break` from the loop
+or call `stream.controller.abort()`.
+
+### Request & Response types
+
+This library includes TypeScript definitions for all request params and response fields. You may import and use them like so:
+
+<!-- prettier-ignore -->
+```ts
+import Opencode from '@opencode-ai/sdk';
+
+const client = new Opencode();
+
+const sessions: Opencode.SessionListResponse = await client.session.list();
+```
+
+Documentation for each method, request param, and response field are available in docstrings and will appear on hover in most modern editors.
+
+## Handling errors
+
+When the library is unable to connect to the API,
+or if the API returns a non-success status code (i.e., 4xx or 5xx response),
+a subclass of `APIError` will be thrown:
+
+<!-- prettier-ignore -->
+```ts
+const sessions = await client.session.list().catch(async (err) => {
+  if (err instanceof Opencode.APIError) {
+    console.log(err.status); // 400
+    console.log(err.name); // BadRequestError
+    console.log(err.headers); // {server: 'nginx', ...}
+  } else {
+    throw err;
+  }
+});
+```
+
+Error codes are as follows:
+
+| Status Code | Error Type                 |
+| ----------- | -------------------------- |
+| 400         | `BadRequestError`          |
+| 401         | `AuthenticationError`      |
+| 403         | `PermissionDeniedError`    |
+| 404         | `NotFoundError`            |
+| 422         | `UnprocessableEntityError` |
+| 429         | `RateLimitError`           |
+| >=500       | `InternalServerError`      |
+| N/A         | `APIConnectionError`       |
+
+### Retries
+
+Certain errors will be automatically retried 2 times by default, with a short exponential backoff.
+Connection errors (for example, due to a network connectivity problem), 408 Request Timeout, 409 Conflict,
+429 Rate Limit, and >=500 Internal errors will all be retried by default.
+
+You can use the `maxRetries` option to configure or disable this:
+
+<!-- prettier-ignore -->
+```js
+// Configure the default for all requests:
+const client = new Opencode({
+  maxRetries: 0, // default is 2
+});
+
+// Or, configure per-request:
+await client.session.list({
+  maxRetries: 5,
+});
+```
+
+### Timeouts
+
+Requests time out after 1 minute by default. You can configure this with a `timeout` option:
+
+<!-- prettier-ignore -->
+```ts
+// Configure the default for all requests:
+const client = new Opencode({
+  timeout: 20 * 1000, // 20 seconds (default is 1 minute)
+});
+
+// Override per-request:
+await client.session.list({
+  timeout: 5 * 1000,
+});
+```
+
+On timeout, an `APIConnectionTimeoutError` is thrown.
+
+Note that requests which time out will be [retried twice by default](#retries).
+
+## Advanced Usage
+
+### Accessing raw Response data (e.g., headers)
+
+The "raw" `Response` returned by `fetch()` can be accessed through the `.asResponse()` method on the `APIPromise` type that all methods return.
+This method returns as soon as the headers for a successful response are received and does not consume the response body, so you are free to write custom parsing or streaming logic.
+
+You can also use the `.withResponse()` method to get the raw `Response` along with the parsed data.
+Unlike `.asResponse()` this method consumes the body, returning once it is parsed.
+
+<!-- prettier-ignore -->
+```ts
+const client = new Opencode();
+
+const response = await client.session.list().asResponse();
+console.log(response.headers.get('X-My-Header'));
+console.log(response.statusText); // access the underlying Response object
+
+const { data: sessions, response: raw } = await client.session.list().withResponse();
+console.log(raw.headers.get('X-My-Header'));
+console.log(sessions);
+```
+
+### Logging
+
+> [!IMPORTANT]
+> All log messages are intended for debugging only. The format and content of log messages
+> may change between releases.
+
+#### Log levels
+
+The log level can be configured in two ways:
+
+1. Via the `OPENCODE_LOG` environment variable
+2. Using the `logLevel` client option (overrides the environment variable if set)
+
+```ts
+import Opencode from '@opencode-ai/sdk';
+
+const client = new Opencode({
+  logLevel: 'debug', // Show all log messages
+});
+```
+
+Available log levels, from most to least verbose:
+
+- `'debug'` - Show debug messages, info, warnings, and errors
+- `'info'` - Show info messages, warnings, and errors
+- `'warn'` - Show warnings and errors (default)
+- `'error'` - Show only errors
+- `'off'` - Disable all logging
+
+At the `'debug'` level, all HTTP requests and responses are logged, including headers and bodies.
+Some authentication-related headers are redacted, but sensitive data in request and response bodies
+may still be visible.
+
+#### Custom logger
+
+By default, this library logs to `globalThis.console`. You can also provide a custom logger.
+Most logging libraries are supported, including [pino](https://www.npmjs.com/package/pino), [winston](https://www.npmjs.com/package/winston), [bunyan](https://www.npmjs.com/package/bunyan), [consola](https://www.npmjs.com/package/consola), [signale](https://www.npmjs.com/package/signale), and [@std/log](https://jsr.io/@std/log). If your logger doesn't work, please open an issue.
+
+When providing a custom logger, the `logLevel` option still controls which messages are emitted, messages
+below the configured level will not be sent to your logger.
+
+```ts
+import Opencode from '@opencode-ai/sdk';
+import pino from 'pino';
+
+const logger = pino();
+
+const client = new Opencode({
+  logger: logger.child({ name: 'Opencode' }),
+  logLevel: 'debug', // Send all messages to pino, allowing it to filter
+});
+```
+
+### Making custom/undocumented requests
+
+This library is typed for convenient access to the documented API. If you need to access undocumented
+endpoints, params, or response properties, the library can still be used.
+
+#### Undocumented endpoints
+
+To make requests to undocumented endpoints, you can use `client.get`, `client.post`, and other HTTP verbs.
+Options on the client, such as retries, will be respected when making these requests.
+
+```ts
+await client.post('/some/path', {
+  body: { some_prop: 'foo' },
+  query: { some_query_arg: 'bar' },
+});
+```
+
+#### Undocumented request params
+
+To make requests using undocumented parameters, you may use `// @ts-expect-error` on the undocumented
+parameter. This library doesn't validate at runtime that the request matches the type, so any extra values you
+send will be sent as-is.
+
+```ts
+client.session.list({
+  // ...
+  // @ts-expect-error baz is not yet public
+  baz: 'undocumented option',
+});
+```
+
+For requests with the `GET` verb, any extra params will be in the query, all other requests will send the
+extra param in the body.
+
+If you want to explicitly send an extra argument, you can do so with the `query`, `body`, and `headers` request
+options.
+
+#### Undocumented response properties
+
+To access undocumented response properties, you may access the response object with `// @ts-expect-error` on
+the response object, or cast the response object to the requisite type. Like the request params, we do not
+validate or strip extra properties from the response from the API.
+
+### Customizing the fetch client
+
+By default, this library expects a global `fetch` function is defined.
+
+If you want to use a different `fetch` function, you can either polyfill the global:
+
+```ts
+import fetch from 'my-fetch';
+
+globalThis.fetch = fetch;
+```
+
+Or pass it to the client:
+
+```ts
+import Opencode from '@opencode-ai/sdk';
+import fetch from 'my-fetch';
+
+const client = new Opencode({ fetch });
+```
+
+### Fetch options
+
+If you want to set custom `fetch` options without overriding the `fetch` function, you can provide a `fetchOptions` object when instantiating the client or making a request. (Request-specific options override client options.)
+
+```ts
+import Opencode from '@opencode-ai/sdk';
+
+const client = new Opencode({
+  fetchOptions: {
+    // `RequestInit` options
+  },
+});
+```
+
+#### Configuring proxies
+
+To modify proxy behavior, you can provide custom `fetchOptions` that add runtime-specific proxy
+options to requests:

+
+## Frequently Asked Questions
+
+## Semantic versioning
+
+This package generally follows [SemVer](https://semver.org/spec/v2.0.0.html) conventions, though certain backwards-incompatible changes may be released as minor versions:
+
+1. Changes that only affect static types, without breaking runtime behavior.
+2. Changes to library internals which are technically public but not intended or documented for external use. _(Please open a GitHub issue to let us know if you are relying on such internals.)_
+3. Changes that we do not expect to impact the vast majority of users in practice.
+
+We take backwards-compatibility seriously and work hard to ensure you can rely on a smooth upgrade experience.
+
+We are keen for your feedback; please open an [issue](https://www.github.com/sst/opencode-sdk-js/issues) with questions, bugs, or suggestions.
+
