+## Using Bedrock Models
+
+To use bedrock models with OpenCode you need three things.
+
+1. Valid AWS credentials (the env vars: `AWS_SECRET_KEY_ID`, `AWS_SECRET_ACCESS_KEY` and `AWS_REGION`)
+2. Access to the corresponding model in AWS Bedrock in your region.
+    a. You can request access in the AWS console on the Bedrock -> "Model access" page.
+3. A correct configuration file. You don't need the `providers` key. Instead you have to prefix your models per agent with `bedrock.` and then a valid model. For now only Claude 3.7 is supported.
+
+```json
+{
+  "agents": {
+    "primary": {
+      "model": "bedrock.claude-3.7-sonnet",

 ```
 
+## Non-interactive Prompt Mode
+
+You can run OpenCode in non-interactive mode by passing a prompt directly as a command-line argument. This is useful for scripting, automation, or when you want a quick answer without launching the full TUI.
+
+```bash
+# Run a single prompt and print the AI's response to the terminal
+opencode -p "Explain the use of context in Go"
+
+# Get response in JSON format
+opencode -p "Explain the use of context in Go" -f json
+
+# Run without showing the spinner
+opencode -p "Explain the use of context in Go" -q
+
+# Enable verbose logging to stderr
+opencode -p "Explain the use of context in Go" --verbose
+
+# Restrict the agent to only use specific tools
+opencode -p "Explain the use of context in Go" --allowedTools=view,ls,glob
+
+# Prevent the agent from using specific tools
+opencode -p "Explain the use of context in Go" --excludedTools=bash,edit
+```
+
+In this mode, OpenCode will process your prompt, print the result to standard output, and then exit. All permissions are auto-approved for the session.
+
+### Tool Restrictions
+
+You can control which tools the AI assistant has access to in non-interactive mode:
+
+- `--allowedTools`: Comma-separated list of tools that the agent is allowed to use. Only these tools will be available.
+- `--excludedTools`: Comma-separated list of tools that the agent is not allowed to use. All other tools will be available.
+
+These flags are mutually exclusive - you can use either `--allowedTools` or `--excludedTools`, but not both at the same time.
+
+### Output Formats
+
+OpenCode supports the following output formats in non-interactive mode:
+
+| Format | Description                            |
+| ------ | -------------------------------------- |
+| `text` | Plain text output (default)            |
+| `json` | Output wrapped in a JSON object        |
+
+The output format is implemented as a strongly-typed `OutputFormat` in the codebase, ensuring type safety and validation when processing outputs.
+

+### Shell Configuration
+
+OpenCode allows you to configure the shell used by the `bash` tool. By default, it uses:
+1. The shell specified in the config file (if provided)
+2. The shell from the `$SHELL` environment variable (if available)
+3. Falls back to `/bin/bash` if neither of the above is available
+
+To configure a custom shell, add a `shell` section to your `.opencode.json` configuration file:

+```json
+{
+  "shell": {
+    "path": "/bin/zsh",
+    "args": ["-l"]

 ### Command Arguments
 
-You can create commands that accept arguments by including the `$ARGUMENTS` placeholder in your command file:
+OpenCode supports named arguments in custom commands using placeholders in the format `$NAME` (where NAME consists of uppercase letters, numbers, and underscores, and must start with a letter).
+
+For example:
 
 ```markdown
-RUN git show $ARGUMENTS
+# Fetch Context for Issue $ISSUE_NUMBER
+
+RUN gh issue view $ISSUE_NUMBER --json title,body,comments
+RUN git grep --author="$AUTHOR_NAME" -n .
+RUN grep -R "$SEARCH_PATTERN" $DIRECTORY
 ```
 
-When you run this command, OpenCode will prompt you to enter the text that should replace `$ARGUMENTS`.
+When you run a command with arguments, OpenCode will prompt you to enter values for each unique placeholder. Named arguments provide several benefits:
+- Clear identification of what each argument represents
+- Ability to use the same argument multiple times
+- Better organization for commands with multiple inputs

+
+WHEN TO USE THIS TOOL:
+- Use when you need to run multiple independent tool calls at once
+- Helpful for improving performance by parallelizing operations
+- Great for gathering information from multiple sources simultaneously
+
+HOW TO USE:
+- Provide an array of tool calls, each with a name and input
+- Each tool call will be executed in parallel
+- Results are returned in the same order as the input calls
+
+FEATURES:
+- Runs tool calls concurrently for better performance
+- Returns both results and errors for each call
+- Maintains the order of results to match input calls
+
+LIMITATIONS:
+- All tools must be available in the current context
+- Complex error handling may be required for some use cases
+- Not suitable for tool calls that depend on each other's results
+
+TIPS:
+- Use for independent operations like multiple file reads or searches
+- Great for batch operations like searching multiple directories
+- Combine with other tools for more complex workflows`

+WHEN TO USE THIS TOOL:
+- Use when you need to find available fixes or refactorings for code issues
+- Helpful for resolving errors, warnings, or improving code quality
+- Great for discovering automated code transformations
+
+HOW TO USE:
+- Provide the path to the file containing the code
+- Specify the line number (1-based) where the action should be applied
+- Specify the column number (1-based) where the action should be applied
+- Optionally specify end_line and end_column to define a range
+- Results show available code actions with their titles and kinds
+
+TO EXECUTE A CODE ACTION:
+- After getting the list of available actions, call the tool again with the same parameters
+- Add action_id parameter with the number of the action you want to execute (e.g., 1 for the first action)
+- Add lsp_name parameter with the name of the LSP server that provided the action
+
+FEATURES:
+- Finds quick fixes for errors and warnings
+- Discovers available refactorings
+- Shows code organization actions
+- Returns detailed information about each action
+- Can execute selected code actions
+
+LIMITATIONS:
+- Requires a functioning LSP server for the file type
+- May not work for all code issues depending on LSP capabilities
+- Results depend on the accuracy of the LSP server
+
+TIPS:
+- Use in conjunction with Diagnostics tool to find issues that can be fixed
+- First call without action_id to see available actions, then call again with action_id to execute
