+# System Browser Detection
+
+MyCoder includes a system browser detection feature that allows it to use your existing installed browsers instead of requiring Playwright's bundled browsers. This is especially useful when MyCoder is installed globally via npm.
+
+## How It Works
+
+When you start a browser session in MyCoder, the system will:
+
+1. Detect available browsers on your system (Chrome, Edge, Firefox, etc.)
+2. Select the most appropriate browser based on your configuration preferences
+3. Launch the browser using Playwright's `executablePath` option
+4. Fall back to Playwright's bundled browsers if no system browser is found
+
+This process happens automatically and is designed to be seamless for the user.
+
+## Supported Browsers
+
+MyCoder can detect and use the following browsers:
+
+### Windows
+- Google Chrome
+- Microsoft Edge
+- Mozilla Firefox
+
+### macOS
+- Google Chrome
+- Google Chrome Canary
+- Microsoft Edge
+- Mozilla Firefox
+- Firefox Developer Edition
+- Firefox Nightly
+
+### Linux
+- Google Chrome
+- Chromium
+- Mozilla Firefox
+
+## Configuration Options
+
+You can customize the browser detection behavior in your `mycoder.config.js` file:
+
+```javascript
+// mycoder.config.js
+export default {
+  // Other settings...
+  
+  // System browser detection settings
+  browser: {
+    // Whether to use system browsers or Playwright's bundled browsers
+    useSystemBrowsers: true,
+
+    // Preferred browser type (chromium, firefox, webkit)
+    preferredType: 'chromium',
+
+    // Custom browser executable path (overrides automatic detection)
+    // executablePath: null, // e.g., '/path/to/chrome'
+  },
+};
+```
+
+### Configuration Options Explained
+
+| Option | Description | Default |
+|--------|-------------|---------|
+| `useSystemBrowsers` | Whether to use system-installed browsers if available | `true` |
+| `preferredType` | Preferred browser engine type (`chromium`, `firefox`, `webkit`) | `chromium` |
+| `executablePath` | Custom browser executable path (overrides automatic detection) | `null` |
+
+## Browser Selection Priority
+
+When selecting a browser, MyCoder follows this priority order:
+
+1. Custom executable path specified in `browser.executablePath` (if provided)
+2. System browser matching the preferred type specified in `browser.preferredType`
+3. Any available system browser
+4. Playwright's bundled browsers (fallback)
+
+## Troubleshooting
+
+If you encounter issues with browser detection:
+
+1. **Browser Not Found**: Ensure you have at least one supported browser installed on your system.
+
+2. **Browser Compatibility Issues**: Some websites may work better with specific browser types. Try changing the `preferredType` setting if you encounter compatibility issues.
+
+3. **Manual Override**: If automatic detection fails, you can manually specify the path to your browser using the `executablePath` option.
+
+4. **Fallback to Bundled Browsers**: If you prefer to use Playwright's bundled browsers, set `useSystemBrowsers` to `false`.
+
+## Examples
+
+### Using Chrome as the Preferred Browser
+
+```javascript
+// mycoder.config.js
+export default {
+  browser: {
+    useSystemBrowsers: true,
+    preferredType: 'chromium',
+  },
+};
+```
+
+### Using Firefox as the Preferred Browser
+
+```javascript
+// mycoder.config.js
+export default {
+  browser: {
+    useSystemBrowsers: true,
+    preferredType: 'firefox',
+  },
+};
+```
+
+### Specifying a Custom Browser Path
+
+```javascript
+// mycoder.config.js
+export default {
+  browser: {
+    useSystemBrowsers: true,
+    executablePath: 'C:\\Program Files\\Google\\Chrome\\Application\\chrome.exe', // Windows example
+    // executablePath: '/Applications/Google Chrome.app/Contents/MacOS/Google Chrome', // macOS example
+    // executablePath: '/usr/bin/google-chrome', // Linux example
+  },
+};
+```

Subject: [PATCH 3/8] feat: Add automatic compaction of historical messages for
 agents

Implements #338 - Agent self-managed message compaction:

1. Enhanced LLM abstraction to track token limits for all providers
2. Added status update mechanism to inform agents about resource usage
3. Created compactHistory tool for summarizing older messages
4. Updated agent documentation and system prompt
5. Added tests for the new functionality
6. Created documentation for the message compaction feature

This feature helps prevent context window overflow errors by
giving agents awareness of their token usage and tools to
manage their context window.

+# Message Compaction
+
+When agents run for extended periods, they accumulate a large history of messages that eventually fills up the LLM's context window, causing errors when the token limit is exceeded. The message compaction feature helps prevent this by providing agents with awareness of their token usage and tools to manage their context window.
+
+## Features
+
+### 1. Token Usage Tracking
+
+The LLM abstraction now tracks and returns:
+- Total tokens used in the current completion request
+- Maximum allowed tokens for the model/provider
+
+This information is used to monitor context window usage and trigger appropriate actions.
+
+### 2. Status Updates
+
+Agents receive periodic status updates (every 5 interactions) with information about:
+- Current token usage and percentage of the maximum
+- Cost so far
+- Active sub-agents and their status
+- Active shell processes and their status
+- Active browser sessions and their status
+
+Example status update:
+```
+--- STATUS UPDATE ---
+Token Usage: 45,235/100,000 (45%)
+Cost So Far: $0.23
+
+Active Sub-Agents: 2
+- sa_12345: Analyzing project structure and dependencies
+- sa_67890: Implementing unit tests for compactHistory tool
+
+Active Shell Processes: 3
+- sh_abcde: npm test
+- sh_fghij: npm run watch
+- sh_klmno: git status
+
+Active Browser Sessions: 1
+- bs_12345: https://www.typescriptlang.org/docs/handbook/utility-types.html
+
+If token usage is high (>70%), consider using the 'compactHistory' tool to reduce context size.
+--- END STATUS ---
+```
+
+### 3. Message Compaction Tool
+
+The `compactHistory` tool allows agents to compact their message history by summarizing older messages while preserving recent context. This tool:
+
+1. Takes a parameter for how many recent messages to preserve unchanged
+2. Summarizes all older messages into a single, concise summary
+3. Replaces the original messages with the summary and preserved messages
+4. Reports on the reduction in context size
+
+## Usage
+
+Agents are instructed to monitor their token usage through status updates and use the `compactHistory` tool when token usage approaches 70% of the maximum:
+
+```javascript
+// Example of agent using the compactHistory tool
+{
+  name: "compactHistory",
+  preserveRecentMessages: 10,
+  customPrompt: "Focus on summarizing our key decisions and current tasks."
+}
+```
+
+## Configuration
+
+The message compaction feature is enabled by default with reasonable defaults:
+- Status updates every 5 agent interactions
+- Recommendation to compact at 70% token usage
+- Default preservation of 10 recent messages when compacting
+
+## Model Token Limits
+
+The system includes token limits for various models:
+
+### Anthropic Models
+- claude-3-opus-20240229: 200,000 tokens
+- claude-3-sonnet-20240229: 200,000 tokens
+- claude-3-haiku-20240307: 200,000 tokens
+- claude-2.1: 100,000 tokens
+
+### OpenAI Models
+- gpt-4o: 128,000 tokens
+- gpt-4-turbo: 128,000 tokens
+- gpt-3.5-turbo: 16,385 tokens
+
+### Ollama Models
+- llama2: 4,096 tokens
+- mistral: 8,192 tokens
+- mixtral: 32,768 tokens
+
+## Benefits
+
+- Prevents context window overflow errors
+- Maintains important context for agent operation
+- Enables longer-running agent sessions
+- Makes the system more robust for complex tasks
+- Gives agents self-awareness of resource usage

+# Example Status Update
+
+This is an example of what the status update looks like for the agent:
+
+```
+--- STATUS UPDATE ---

+
+If token usage is high (>70%), consider using the 'compactHistory' tool to reduce context size.
+--- END STATUS ---
+```
+
+## About Status Updates
+
+Status updates are sent periodically to the agent (every 5 interactions) to provide awareness of:
+
+1. **Token Usage**: Current usage and percentage of maximum context window
+2. **Cost**: Estimated cost of the session so far
+3. **Active Sub-Agents**: Running background agents and their tasks
+4. **Active Shell Processes**: Running shell commands
+5. **Active Browser Sessions**: Open browser sessions and their URLs
+
+When token usage gets high (>70%), the agent is reminded to use the `compactHistory` tool to reduce context size by summarizing older messages.
+
+## Using the compactHistory Tool
+
+The agent can use the compactHistory tool like this:
+
+```javascript
+{
+  name: "compactHistory",
+  preserveRecentMessages: 10,
+  customPrompt: "Optional custom summarization prompt"
+}
+```
+
+This will summarize all but the 10 most recent messages into a single summary message, significantly reducing token usage while preserving important context.

+# Message Compaction
+
+When agents run for extended periods, they accumulate a large history of messages that eventually fills up the LLM's context window, causing errors when the token limit is exceeded. The message compaction feature helps prevent this by providing agents with awareness of their token usage and tools to manage their context window.
+
+## How It Works
+
+### Token Usage Tracking
+
+MyCoder's LLM abstraction tracks and returns:
+- Total tokens used in the current completion request
+- Maximum allowed tokens for the model/provider
+
+This information is used to monitor context window usage and trigger appropriate actions.
+
+### Status Updates
+
+Agents receive status updates with information about:
+- Current token usage and percentage of the maximum
+- Cost so far
+- Active sub-agents and their status
+- Active shell processes and their status
+- Active browser sessions and their status
+
+Status updates are sent:
+1. Every 5 agent interactions (periodic updates)
+2. Whenever token usage exceeds 50% of the maximum (threshold-based updates)
+
+Example status update:
+```
+--- STATUS UPDATE ---
+Token Usage: 45,235/100,000 (45%)
+Cost So Far: $0.23
+
+Active Sub-Agents: 2
+- sa_12345: Analyzing project structure and dependencies
+- sa_67890: Implementing unit tests for compactHistory tool
+
+Active Shell Processes: 3
+- sh_abcde: npm test
+- sh_fghij: npm run watch
+- sh_klmno: git status
+
+Active Browser Sessions: 1
+- bs_12345: https://www.typescriptlang.org/docs/handbook/utility-types.html
+
+Your token usage is high (45%). It is recommended to use the 'compactHistory' tool now to reduce context size.
+--- END STATUS ---
+```
+
+### Message Compaction Tool
+
+The `compactHistory` tool allows agents to compact their message history by summarizing older messages while preserving recent context. This tool:
+
+1. Takes a parameter for how many recent messages to preserve unchanged
+2. Summarizes all older messages into a single, concise summary
+3. Replaces the original messages with the summary and preserved messages
+4. Reports on the reduction in context size
+
+## Usage
+
+Agents are instructed to monitor their token usage through status updates and use the `compactHistory` tool when token usage approaches 50% of the maximum:
+
+```javascript
+// Example of agent using the compactHistory tool
+{
+  name: "compactHistory",
+  preserveRecentMessages: 10,
+  customPrompt: "Focus on summarizing our key decisions and current tasks."
+}
+```
+
+### Parameters
+
+The `compactHistory` tool accepts the following parameters:
+
+| Parameter | Type | Description | Default |
+|-----------|------|-------------|---------|
+| `preserveRecentMessages` | number | Number of recent messages to preserve unchanged | 10 |
+| `customPrompt` | string (optional) | Custom prompt for the summarization | Default compaction prompt |
+
+## Benefits
+
+- Prevents context window overflow errors
+- Maintains important context for agent operation
+- Enables longer-running agent sessions
+- Makes the system more robust for complex tasks
+- Gives agents self-awareness of resource usage
+
+## Model Token Limits
+
+MyCoder includes token limits for various models:
+
+### Anthropic Models
+- claude-3-opus-20240229: 200,000 tokens
+- claude-3-sonnet-20240229: 200,000 tokens
+- claude-3-haiku-20240307: 200,000 tokens
+- claude-2.1: 100,000 tokens
+
+### OpenAI Models
+- gpt-4o: 128,000 tokens
+- gpt-4-turbo: 128,000 tokens
+- gpt-3.5-turbo: 16,385 tokens
+
+### Ollama Models
+- llama2: 4,096 tokens
+- mistral: 8,192 tokens
+- mixtral: 32,768 tokens

# [mycoder-agent-v1.7.0](https://github.com/drivecore/mycoder/compare/mycoder-agent-v1.6.0...mycoder-agent-v1.7.0) (2025-03-21)

### Bug Fixes

* Fix TypeScript errors and tests for message compaction feature ([d4f1fb5](https://github.com/drivecore/mycoder/commit/d4f1fb5d197e623bf98f2221352f9132dcb3e5de))

### Features

* Add automatic compaction of historical messages for agents ([a5caf46](https://github.com/drivecore/mycoder/commit/a5caf464a0a8dca925c7b46023ebde4727e211f8)), closes [#338](https://github.com/drivecore/mycoder/issues/338)
* Improve message compaction with proactive suggestions ([6276bc0](https://github.com/drivecore/mycoder/commit/6276bc0bc5fa27c4f1e9be61ff4375690ad04c62))
