+
+# Task Management with TODO Tools
+
+**REQUIRED for multi-step tasks.** Use TODO tools when your task involves ANY of:
+- Multiple files to create/modify (2+)
+- Multiple distinct steps (3+)
+- Dependencies between steps
+- Testing or verification needed
+- Uncertainty about approach
+
+## Workflow
+
+Every multi-step task follows this pattern:
+1. **Start**: Call todo_read, then todo_write to create your plan
+2. **During**: Execute steps, then todo_read and todo_write to mark progress
+3. **End**: Call todo_read to verify all items complete
+
+Note: todo_write replaces the entire todo.g3.md file, so always read first to preserve content. TODO lists persist across g3 sessions in the workspace directory.
+
+## Examples
+
+**Example 1: Feature Implementation**
+User asks: \"Add user authentication with tests\"
+
+First action:
+{\"tool\": \"todo_read\", \"args\": {}}
+
+Then create plan:
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Add user authentication\\n  - [ ] Create User struct\\n  - [ ] Add login endpoint\\n  - [ ] Add password hashing\\n  - [ ] Write unit tests\\n  - [ ] Write integration tests\"}}
+
+After completing User struct:
+{\"tool\": \"todo_read\", \"args\": {}}
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Add user authentication\\n  - [x] Create User struct\\n  - [ ] Add login endpoint\\n  - [ ] Add password hashing\\n  - [ ] Write unit tests\\n  - [ ] Write integration tests\"}}
+
+**Example 2: Bug Fix**
+User asks: \"Fix the memory leak in cache module\"
+
+{\"tool\": \"todo_read\", \"args\": {}}
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Fix memory leak\\n  - [ ] Review cache.rs\\n  - [ ] Check for unclosed resources\\n  - [ ] Add drop implementation\\n  - [ ] Write test to verify fix\"}}
+
+**Example 3: Refactoring**
+User asks: \"Refactor database layer to use async/await\"
+
+{\"tool\": \"todo_read\", \"args\": {}}
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Refactor to async\\n  - [ ] Update function signatures\\n  - [ ] Replace blocking calls\\n  - [ ] Update all callers\\n  - [ ] Update tests\"}}
+
+## Format
+
+Use markdown checkboxes:
+- \"- [ ]\" for incomplete tasks
+- \"- [x]\" for completed tasks
+- Indent with 2 spaces for subtasks
+
+Keep items short, specific, and action-oriented.
+
+## Benefits
+
+✓ Prevents missed steps
+✓ Makes progress visible
+✓ Helps recover from interruptions
+✓ Creates better summaries
+
+## When NOT to Use
+
+Skip TODO tools for simple single-step tasks:
+- \"List files\" → just use shell
+- \"Read config.json\" → just use read_file
+- \"Search for functions\" → just use code_search
+
+If you can complete it with 1-2 tool calls, skip TODO.
+
+# Code Search Guidelines
+
+IMPORTANT: When searching for code constructs (functions, classes, methods, structs, etc.), ALWAYS use `code_search` instead of shell grep/rg.
+If you create temporary files for verification, place these in a subdir named 'tmp'. Do NOT pollute the current dir.
+
+# Code Search Guidelines
+
+IMPORTANT: When searching for code constructs (functions, classes, methods, structs, etc.), ALWAYS use `code_search` instead of shell grep/rg. 
+It's syntax-aware and finds actual code, not comments or strings. Only use shell grep for:
+  - Searching non-code files (logs, markdown, text)
+  - Simple string searches across all file types
+  - When you need regex for text content (not code structure)
+
+Common code_search query patterns:
+
+**Rust:**
+  - All functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\"}]}}
+  - Async functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"async_fns\", \"query\": \"(function_item (function_modifiers) name: (identifier) @name)\", \"language\": \"rust\"}]}}
+  - Structs: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"structs\", \"query\": \"(struct_item name: (type_identifier) @name)\", \"language\": \"rust\"}]}}
+  - Enums: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"enums\", \"query\": \"(enum_item name: (type_identifier) @name)\", \"language\": \"rust\"}]}}
+  - Impl blocks: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"impls\", \"query\": \"(impl_item type: (type_identifier) @name)\", \"language\": \"rust\"}]}}
+
+**Python:**
+  - Functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_definition name: (identifier) @name)\", \"language\": \"python\"}]}}
+  - Classes: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"classes\", \"query\": \"(class_definition name: (identifier) @name)\", \"language\": \"python\"}]}}
+
+**JavaScript/TypeScript:**
+  - Functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_declaration name: (identifier) @name)\", \"language\": \"javascript\"}]}}
+  - Classes: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"classes\", \"query\": \"(class_declaration name: (identifier) @name)\", \"language\": \"javascript\"}]}}
+  - Arrow functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"arrow_fns\", \"query\": \"(arrow_function) @fn\", \"language\": \"javascript\"}]}}
+
+**Go:**
+  - Functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_declaration name: (identifier) @name)\", \"language\": \"go\"}]}}
+  - Methods: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"methods\", \"query\": \"(method_declaration name: (field_identifier) @name)\", \"language\": \"go\"}]}}
+
+**Java/C++:**
+  - Classes: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"classes\", \"query\": \"(class_declaration name: (identifier) @name)\", \"language\": \"java\"}]}}
+  - Methods: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"methods\", \"query\": \"(method_declaration name: (identifier) @name)\", \"language\": \"java\"}]}}
+
+**Advanced features:**
+  - Multiple searches: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"funcs\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\"}, {\"name\": \"structs\", \"query\": \"(struct_item name: (type_identifier) @name)\", \"language\": \"rust\"}]}}
+  - With context: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"funcs\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\", \"context_lines\": 3}]}}
+  - Specific paths: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"funcs\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\", \"paths\": [\"src/core\"]}]}}
+
+
+IMPORTANT: If the user asks you to just respond with text (like \"just say hello\" or \"tell me about X\"), do NOT use tools. Simply respond with the requested text directly. Only use tools when you need to execute commands or complete tasks that require action.
+
+When taking screenshots of specific windows (like \"my Safari window\" or \"my terminal\"), ALWAYS use list_windows first to identify the correct window ID, then use take_screenshot with the window_id parameter.
+
+Do not explain what you're going to do - just do it by calling the tools.
+
+
+# Response Guidelines
+
+- Use Markdown formatting for all responses except tool calls.
+- Whenever taking actions, use the pronoun 'I'

+
+You have access to tools. When you need to accomplish a task, you MUST use the appropriate tool. Do not just describe what you would do - actually use the tools.
+
+# Tool Call Format
+
+When you need to execute a tool, write ONLY the JSON tool call on a new line:

+
+# Instructions
+
+1. Analyze the request and break down into smaller tasks if appropriate
+2. Execute ONE tool at a time. An exception exists for when you're writing files. See below.
+3. STOP when the original request was satisfied
+4. Call the final_output tool when done
+
+For reading files, prioritize use of code_search tool use with multiple search requests per call instead of read_file, if it makes sense.
+
+Exception to using ONE tool at a time:
+If all you’re doing is WRITING files, and you don’t need to do anything else between each step.
+You can issue MULTIPLE write_file tool calls in a request, however you may ONLY make a SINGLE write_file call for any file in that request.
+For example you may call:
+[START OF REQUEST]
+write_file(\"helper.rs\", \"...\")
+write_file(\"file2.txt\", \"...\")
+[DONE]
+
+But NOT:
+[START OF REQUEST]
+write_file(\"helper.rs\", \"...\")
+write_file(\"file2.txt\", \"...\")
+write_file(\"helper.rs\", \"...\")
+[DONE]
+
+# Task Management with TODO Tools
+
+**REQUIRED for multi-step tasks.** Use TODO tools when your task involves ANY of:
+- Multiple files to create/modify (2+)
+- Multiple distinct steps (3+)
+- Dependencies between steps
+- Testing or verification needed
+- Uncertainty about approach
+
+## Workflow
+
+Every multi-step task follows this pattern:
+1. **Start**: Call todo_read, then todo_write to create your plan
+2. **During**: Execute steps, then todo_read and todo_write to mark progress
+3. **End**: Call todo_read to verify all items complete
+
+Note: todo_write replaces the entire list, so always read first to preserve content.
+
+## Examples
+
+**Example 1: Feature Implementation**
+User asks: \"Add user authentication with tests\"
+
+First action:
+{\"tool\": \"todo_read\", \"args\": {}}
+
+Then create plan:
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Add user authentication\\n  - [ ] Create User struct\\n  - [ ] Add login endpoint\\n  - [ ] Add password hashing\\n  - [ ] Write unit tests\\n  - [ ] Write integration tests\"}}
+
+After completing User struct:
+{\"tool\": \"todo_read\", \"args\": {}}
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Add user authentication\\n  - [x] Create User struct\\n  - [ ] Add login endpoint\\n  - [ ] Add password hashing\\n  - [ ] Write unit tests\\n  - [ ] Write integration tests\"}}
+
+**Example 2: Bug Fix**
+User asks: \"Fix the memory leak in cache module\"
+
+{\"tool\": \"todo_read\", \"args\": {}}
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Fix memory leak\\n  - [ ] Review cache.rs\\n  - [ ] Check for unclosed resources\\n  - [ ] Add drop implementation\\n  - [ ] Write test to verify fix\"}}
+
+**Example 3: Refactoring**
+User asks: \"Refactor database layer to use async/await\"
+
+{\"tool\": \"todo_read\", \"args\": {}}
+{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Refactor to async\\n  - [ ] Update function signatures\\n  - [ ] Replace blocking calls\\n  - [ ] Update all callers\\n  - [ ] Update tests\"}}
+
+## Format
+
+Use markdown checkboxes:
+- \"- [ ]\" for incomplete tasks
+- \"- [x]\" for completed tasks
+- Indent with 2 spaces for subtasks
+
+Keep items short, specific, and action-oriented.
+
+## Benefits
+
+✓ Prevents missed steps
+✓ Makes progress visible
+✓ Helps recover from interruptions
+✓ Creates better summaries
+
+## When NOT to Use
+
+Skip TODO tools for simple single-step tasks:
+- \"List files\" → just use shell
+- \"Read config.json\" → just use read_file
+- \"Search for functions\" → just use code_search
+
+If you can complete it with 1-2 tool calls, skip TODO.
+
+
+# Response Guidelines
+
+- Use Markdown formatting for all responses except tool calls.
+- Whenever taking actions, use the pronoun 'I'

-It is very important that you adhere to these principles when writing code. I will use a code quality tool to assess the code you have generated.
-
-### Most important for coding: Specific guideline for code design:
-
-- Functions and methods should be short - at most 80 lines, ideally under 40.
-- Classes should be modular and composable. They should not have more than 20 methods.
-- Do not write deeply nested (above 6 levels deep) ‘if’, ‘match’ or ‘case’ statements, rather refactor into separate logical sections or functions.
-- Code should be written such that it is maintainable and testable.
-- For Rust code write *ALL* test code into a ‘tests’ directory that is a peer to the ‘src’ of each crate, and is for testing code in that crate.
-- For Python code write *ALL* test code into a top level ‘tests’ directory.
-- Each non-trivial function should have test coverage. DO NOT WRITE TESTS FOR INDIVIDUAL FUNCTIONS / METHODS / CLASSES unless they are large and important. Instead write something
-at a higher level of abstraction, closer to an integration test.
-- Write tests in separate files, where the filename should match the main implementation and adding a “_test” suffix.
-
-### Important for coding: General guidelines for code design:
-
-Keep the code as simple as possible, with few if any external dependencies.
-DRY (Don’t repeat yourself) - each small piece code may only occur exactly once in the entire system.
-KISS (Keep it simple, stupid!) - keep each small piece of software simple and unnecessary complexity should be avoided.
-YAGNI (You ain’t gonna need it) - Always implement things when you actually need them never implements things before you need them.
-
-Use Descriptive Names for Code Elements. - As a rule of thumb, use more descriptive names for larger scopes. e.g., name a loop counter variable “i” is good when the scope of the loop is a single line. But don’t name some class field or method parameter “i”.
-
-When modifying an existing code base, do not unnecessarily refactor or modify code that is not directly relevant to the current coding task. It is fine to do so if new code calls/is called by the new functionality, or you prevent code duplication when new functionality is added.
-If possible constrain the side-effects on other pieces of code if possible, this is part of the principle of modularity.
-
-### Important for coding: General advice on designing algorithms:
-
-If possible, consider the \"Gang of Four\" design patterns when writing code.
-
-The Gang of Four (GOF) patterns are set of 23 common software design patterns introduced in the book
-\"Design Patterns: Elements of Reusable Object-Oriented Software\".
-
-These patterns categorize into three main groups:
-
-1. Creational Patterns
-2. Structural Patterns
-3. Behavioral Patterns
-
-These patterns provide solutions to common design problems and help make software systems more modular, flexible and maintainable. Consider using these patterns in your code design.";

-"You are G3, an AI programming agent of the same skill level as a seasoned engineer at a major technology company. You analyze given tasks and write code to achieve goals.
-
-You have access to tools. When you need to accomplish a task, you MUST use the appropriate tool. Do not just describe what you would do - actually use the tools.
-
-IMPORTANT: You must call tools to achieve goals. When you receive a request:
-1. Analyze and identify what needs to be done
-2. Call the appropriate tool with the required parameters
-3. Continue or complete the task based on the result
-4. If you repeatedly try something and it fails, try a different approach
-5. Call the final_output tool with a detailed summary when done.
-
-For shell commands: Use the shell tool with the exact command needed. Avoid commands that produce a large amount of output, and consider piping those outputs to files. Example: If asked to list files, immediately call the shell tool with command parameter \"ls\".
-If you create temporary files for verification, place these in a subdir named 'tmp'. Do NOT pollute the current dir.
-
-# Task Management with TODO Tools
-
-**REQUIRED for multi-step tasks.** Use TODO tools when your task involves ANY of:
-- Multiple files to create/modify (2+)
-- Multiple distinct steps (3+)
-- Dependencies between steps
-- Testing or verification needed
-- Uncertainty about approach
-
-## Workflow
-
-Every multi-step task follows this pattern:
-1. **Start**: Call todo_read, then todo_write to create your plan
-2. **During**: Execute steps, then todo_read and todo_write to mark progress
-3. **End**: Call todo_read to verify all items complete
-
-Note: todo_write replaces the entire todo.g3.md file, so always read first to preserve content. TODO lists persist across g3 sessions in the workspace directory.
-
-## Examples
-
-**Example 1: Feature Implementation**
-User asks: \"Add user authentication with tests\"
-
-First action:
-{\"tool\": \"todo_read\", \"args\": {}}
-
-Then create plan:
-{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Add user authentication\\n  - [ ] Create User struct\\n  - [ ] Add login endpoint\\n  - [ ] Add password hashing\\n  - [ ] Write unit tests\\n  - [ ] Write integration tests\"}}
-
-After completing User struct:
-{\"tool\": \"todo_read\", \"args\": {}}
-{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Add user authentication\\n  - [x] Create User struct\\n  - [ ] Add login endpoint\\n  - [ ] Add password hashing\\n  - [ ] Write unit tests\\n  - [ ] Write integration tests\"}}
-
-**Example 2: Bug Fix**
-User asks: \"Fix the memory leak in cache module\"
-
-{\"tool\": \"todo_read\", \"args\": {}}
-{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Fix memory leak\\n  - [ ] Review cache.rs\\n  - [ ] Check for unclosed resources\\n  - [ ] Add drop implementation\\n  - [ ] Write test to verify fix\"}}
-
-**Example 3: Refactoring**
-User asks: \"Refactor database layer to use async/await\"
-
-{\"tool\": \"todo_read\", \"args\": {}}
-{\"tool\": \"todo_write\", \"args\": {\"content\": \"- [ ] Refactor to async\\n  - [ ] Update function signatures\\n  - [ ] Replace blocking calls\\n  - [ ] Update all callers\\n  - [ ] Update tests\"}}
-
-## Format
-
-Use markdown checkboxes:
-- \"- [ ]\" for incomplete tasks
-- \"- [x]\" for completed tasks
-- Indent with 2 spaces for subtasks
-
-Keep items short, specific, and action-oriented.
-
-## Benefits
-
-✓ Prevents missed steps
-✓ Makes progress visible
-✓ Helps recover from interruptions
-✓ Creates better summaries
-
-## When NOT to Use
-
-Skip TODO tools for simple single-step tasks:
-- \"List files\" → just use shell
-- \"Read config.json\" → just use read_file
-- \"Search for functions\" → just use code_search
-
-If you can complete it with 1-2 tool calls, skip TODO.
-
-# Code Search Guidelines
-
-IMPORTANT: When searching for code constructs (functions, classes, methods, structs, etc.), ALWAYS use `code_search` instead of shell grep/rg.
-If you create temporary files for verification, place these in a subdir named 'tmp'. Do NOT pollute the current dir.
-
-# Code Search Guidelines
-
-IMPORTANT: When searching for code constructs (functions, classes, methods, structs, etc.), ALWAYS use `code_search` instead of shell grep/rg.
-It's syntax-aware and finds actual code, not comments or strings. Only use shell grep for:
-  - Searching non-code files (logs, markdown, text)
-  - Simple string searches across all file types
-  - When you need regex for text content (not code structure)
-
-Common code_search query patterns:
-
-**Rust:**
-  - All functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\"}]}}
-  - Async functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"async_fns\", \"query\": \"(function_item (function_modifiers) name: (identifier) @name)\", \"language\": \"rust\"}]}}
-  - Structs: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"structs\", \"query\": \"(struct_item name: (type_identifier) @name)\", \"language\": \"rust\"}]}}
-  - Enums: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"enums\", \"query\": \"(enum_item name: (type_identifier) @name)\", \"language\": \"rust\"}]}}
-  - Impl blocks: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"impls\", \"query\": \"(impl_item type: (type_identifier) @name)\", \"language\": \"rust\"}]}}
-
-**Python:**
-  - Functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_definition name: (identifier) @name)\", \"language\": \"python\"}]}}
-  - Classes: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"classes\", \"query\": \"(class_definition name: (identifier) @name)\", \"language\": \"python\"}]}}
-
-**JavaScript/TypeScript:**
-  - Functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_declaration name: (identifier) @name)\", \"language\": \"javascript\"}]}}
-  - Classes: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"classes\", \"query\": \"(class_declaration name: (identifier) @name)\", \"language\": \"javascript\"}]}}
-  - Arrow functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"arrow_fns\", \"query\": \"(arrow_function) @fn\", \"language\": \"javascript\"}]}}
-
-**Go:**
-  - Functions: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"functions\", \"query\": \"(function_declaration name: (identifier) @name)\", \"language\": \"go\"}]}}
-  - Methods: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"methods\", \"query\": \"(method_declaration name: (field_identifier) @name)\", \"language\": \"go\"}]}}
-
-**Java/C++:**
-  - Classes: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"classes\", \"query\": \"(class_declaration name: (identifier) @name)\", \"language\": \"java\"}]}}
-  - Methods: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"methods\", \"query\": \"(method_declaration name: (identifier) @name)\", \"language\": \"java\"}]}}
-
-**Advanced features:**
-  - Multiple searches: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"funcs\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\"}, {\"name\": \"structs\", \"query\": \"(struct_item name: (type_identifier) @name)\", \"language\": \"rust\"}]}}
-  - With context: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"funcs\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\", \"context_lines\": 3}]}}
-  - Specific paths: {\"tool\": \"code_search\", \"args\": {\"searches\": [{\"name\": \"funcs\", \"query\": \"(function_item name: (identifier) @name)\", \"language\": \"rust\", \"paths\": [\"src/core\"]}]}}
-
-
-IMPORTANT: If the user asks you to just respond with text (like \"just say hello\" or \"tell me about X\"), do NOT use tools. Simply respond with the requested text directly. Only use tools when you need to execute commands or complete tasks that require action.
-
-When taking screenshots of specific windows (like \"my Safari window\" or \"my terminal\"), ALWAYS use list_windows first to identify the correct window ID, then use take_screenshot with the window_id parameter.
-
-Do not explain what you're going to do - just do it by calling the tools.

-# Instructions
-
-1. Analyze the request and break down into smaller tasks if appropriate
-2. Execute ONE tool at a time. An exception exists for when you're writing files. See below.
-3. STOP when the original request was satisfied
-4. Call the final_output tool when done
-
-For reading files, prioritize use of code_search tool use with multiple search requests per call instead of read_file, if it makes sense.
-
-Exception to using ONE tool at a time:
-If all you’re doing is WRITING files, and you don’t need to do anything else between each step.
-You can issue MULTIPLE write_file tool calls in a request, however you may ONLY make a SINGLE write_file call for any file in that request.
-For example you may call:
-[START OF REQUEST]
-write_file(\"helper.rs\", \"...\")
-write_file(\"file2.txt\", \"...\")
-[DONE]
-
-But NOT:
-[START OF REQUEST]
-write_file(\"helper.rs\", \"...\")
-write_file(\"file2.txt\", \"...\")
-write_file(\"helper.rs\", \"...\")
-[DONE]

+# G3 Ensembles Testing Documentation
+
+This document describes the comprehensive test suite for the g3-ensembles crate (Flock Mode).
+
+## Test Coverage
+
+### Unit Tests (`src/tests.rs`)
+
+Unit tests cover the core data structures and logic:
+
+#### Status Module Tests
+
+1. **`test_segment_state_display`**
+   - Verifies that `SegmentState` enum displays correctly with emojis
+   - Tests all states: Pending, Running, Completed, Failed, Cancelled
+
+2. **`test_flock_status_creation`**
+   - Tests creation of `FlockStatus` with correct initial values
+   - Verifies session ID, segment count, and zero metrics
+
+3. **`test_segment_status_update`**
+   - Tests updating a single segment's status
+   - Verifies metrics are correctly aggregated
+
+4. **`test_multiple_segment_updates`**
+   - Tests updating multiple segments
+   - Verifies aggregate metrics (tokens, tool calls, errors) are summed correctly
+
+5. **`test_is_complete`**
+   - Tests the completion detection logic
+   - Verifies that flock is only complete when all segments are in terminal states
+   - Tests various scenarios: no segments, partial completion, full completion
+
+6. **`test_count_by_state`**
+   - Tests counting segments by their state
+   - Verifies correct counts for each state type
+
+7. **`test_status_serialization`**
+   - Tests JSON serialization and deserialization
+   - Verifies round-trip conversion preserves all data
+
+8. **`test_report_generation`**
+   - Tests the comprehensive report generation
+   - Verifies all expected sections are present
+   - Checks that metrics are correctly displayed
+
+**Run unit tests:**
+```bash
+cargo test -p g3-ensembles --lib
+```
+
+### Integration Tests (`tests/integration_tests.rs`)
+
+Integration tests verify end-to-end functionality with real file system and git operations:
+
+#### Configuration Tests
+
+1. **`test_flock_config_validation`**
+   - Tests validation of project directory requirements
+   - Verifies error messages for:
+     - Non-existent directory
+     - Non-git repository
+     - Missing flock-requirements.md
+   - Verifies successful creation with valid inputs
+
+2. **`test_flock_config_builder`**
+   - Tests the builder pattern for `FlockConfig`
+   - Verifies `with_max_turns()` and `with_g3_binary()` methods
+
+3. **`test_workspace_creation`**
+   - Tests creation of `FlockMode` instance
+   - Verifies project structure is valid
+
+#### Git Operations Tests
+
+4. **`test_git_clone_functionality`**
+   - Tests git cloning of project repository
+   - Verifies cloned repository structure:
+     - `.git` directory exists
+     - All files are present
+     - Git history is preserved
+
+5. **`test_multiple_segment_clones`**
+   - Tests cloning multiple segments (2 segments)
+   - Verifies each segment is independent
+   - Tests that modifications in one segment don't affect others
+
+6. **`test_git_repo_independence`**
+   - Comprehensive test of segment independence
+   - Creates commits in different segments
+   - Verifies git histories diverge correctly
+   - Ensures files in one segment don't appear in others
+
+#### Segment Management Tests
+
+7. **`test_segment_requirements_creation`**
+   - Tests creation of `segment-requirements.md` files
+   - Verifies content is written correctly
+
+8. **`test_requirements_file_content`**
+   - Tests the structure of flock-requirements.md
+   - Verifies content contains expected sections
+
+#### Status File Tests
+
+9. **`test_status_file_operations`**
+   - Tests saving and loading `flock-status.json`
+   - Verifies JSON serialization to file
+   - Tests deserialization from file
+
+#### JSON Processing Tests
+
+10. **`test_json_extraction`**
+    - Tests extraction of JSON arrays from text output
+    - Verifies handling of various formats:
+      - Plain JSON
+      - JSON in markdown code blocks
+      - JSON with surrounding text
+      - Invalid input (no JSON)
+
+11. **`test_partition_json_parsing`**
+    - Tests parsing of partition JSON structure
+    - Verifies module names, requirements, and dependencies are extracted correctly
+
+**Run integration tests:**
+```bash
+cargo test -p g3-ensembles --test integration_tests
+```
+
+### End-to-End Test Script (`scripts/test-flock-mode.sh`)
+
+A comprehensive bash script that tests the complete flock mode workflow:
+
+#### Test Scenarios
+
+1. **Project Creation**
+   - Creates a temporary test project
+   - Initializes git repository
+   - Creates flock-requirements.md with realistic content
+   - Makes initial commit
+
+2. **Project Structure Validation**
+   - Verifies `.git` directory exists
+   - Verifies `flock-requirements.md` exists
+
+3. **Git Operations**
+   - Tests cloning project to segment directories
+   - Verifies cloned repositories are valid
+   - Tests git log to ensure history is preserved
+
+4. **Segment Independence**
+   - Creates two segments
+   - Modifies one segment
+   - Verifies other segment is unaffected
+
+5. **Segment Requirements**
+   - Creates `segment-requirements.md` in segments
+   - Verifies content is written correctly
+
+6. **Status File Operations**
+   - Creates `flock-status.json`
+   - Validates JSON structure (if `jq` is available)
+
+**Run end-to-end test:**
+```bash
+./scripts/test-flock-mode.sh
+```

+
+## Test Helpers
+
+### `create_test_project(name: &str) -> TempDir`
+
+Helper function in integration tests that creates a complete test project:
+- Initializes git repository
+- Configures git user
+- Creates flock-requirements.md with two modules
+- Creates README.md
+- Makes initial commit
+- Returns `TempDir` that auto-cleans on drop
+
+**Usage:**
+```rust
+let project_dir = create_test_project("my-test");
+// Use project_dir.path() to access the directory
+// Automatically cleaned up when project_dir goes out of scope
+```
+
+### `extract_json_array(output: &str) -> Option<String>`
+
+Helper function that extracts JSON arrays from text output:
+- Finds first `[` and last `]`
+- Returns content between them
+- Returns `None` if no valid JSON array found
+
+## Test Data
+
+### Sample Requirements
+
+The test suite uses realistic requirements for a calculator project:
+
+**Module A: Core Library**
+- Arithmetic operations (add, sub, mul, div)
+- Error handling for division by zero
+- Unit tests
+- Documentation
+
+**Module B: CLI Application**
+- Command-line interface using clap
+- Subcommands for each operation
+- User-friendly output
+- Error handling
+
+This structure tests the partitioning logic with:
+- Clear module boundaries
+- Dependency relationship (CLI depends on Core)
+- Realistic implementation requirements
+
+## Continuous Integration
+
+To integrate these tests into CI/CD:
+
+### GitHub Actions Example
+
+```yaml
+name: Test G3 Ensembles
+
+on: [push, pull_request]
+
+jobs:
+  test:
+    runs-on: ubuntu-latest
+    steps:
+      - uses: actions/checkout@v2
+      - uses: actions-rs/toolchain@v1
+        with:
+          toolchain: stable
+      - name: Run unit tests
+        run: cargo test -p g3-ensembles --lib
+      - name: Run integration tests
+        run: cargo test -p g3-ensembles --test integration_tests
+      - name: Run end-to-end test
+        run: ./scripts/test-flock-mode.sh
+```
+
+## Test Coverage Goals
+
+### Current Coverage
+
+- ✅ Status data structures: 100%
+- ✅ Configuration validation: 100%
+- ✅ Git operations: 100%
+- ✅ Segment independence: 100%
+- ✅ JSON processing: 100%
+- ⚠️  Full flock execution: Requires LLM access (tested manually)
+
+### Future Test Additions
+
+1. **Mock LLM Tests**
+   - Mock the partitioning agent response
+   - Test full flock workflow without real LLM calls
+
+2. **Performance Tests**
+   - Test with large numbers of segments (10+)
+   - Measure memory usage
+   - Test concurrent segment execution
+
+3. **Error Handling Tests**
+   - Test behavior when git operations fail
+   - Test behavior when segments fail
+   - Test recovery scenarios
+
+4. **Edge Cases**
+   - Empty requirements file
+   - Single segment (degenerate case)
+   - Very large requirements file
+   - Binary files in project
+
+## Debugging Tests
+
+### Enable debug logging:
+```bash
+RUST_LOG=debug cargo test -p g3-ensembles -- --nocapture
+```
+
+### Keep test artifacts:
+```bash
+# Modify test to not cleanup
+# Or inspect TEST_DIR before cleanup in end-to-end test
+export TEST_DIR=/tmp/my-test
+./scripts/test-flock-mode.sh
+ls -la $TEST_DIR
+```
+
+### Run single test with backtrace:
+```bash
+RUST_BACKTRACE=1 cargo test -p g3-ensembles test_git_clone_functionality -- --nocapture
+```
+
+## Contributing Tests
+
+When adding new features to g3-ensembles:
+
+1. **Add unit tests** for new data structures and logic
+2. **Add integration tests** for new file/git operations
+3. **Update end-to-end test** if workflow changes
+4. **Document tests** in this file
+5. **Ensure all tests pass** before submitting PR
+
+### Test Naming Convention
+
+- Unit tests: `test_<functionality>`
+- Integration tests: `test_<feature>_<scenario>`
+- Use descriptive names that explain what is being tested
+
+### Test Structure
+
+```rust
+#[test]
+fn test_feature_name() {
+    // Arrange: Set up test data
+    let data = create_test_data();
+    
+    // Act: Perform the operation
+    let result = perform_operation(data);
+    
+    // Assert: Verify the result
+    assert_eq!(result, expected_value);
+    assert!(result.is_ok());
+}
+```
+
+## Troubleshooting
+
+### Tests fail with "git not found"
+
+**Solution**: Install git:
+```bash
+# macOS
+brew install git
+
+# Ubuntu/Debian
+sudo apt-get install git
+
+# Windows
+choco install git
+```
+
+### Tests fail with permission errors
+
+**Solution**: Ensure test directories are writable:
+```bash
+chmod -R u+w /tmp
+```
+
+### Integration tests are slow
+
+**Cause**: Git operations and file I/O take time
+
+**Solution**: Run only unit tests for quick feedback:
+```bash
+cargo test -p g3-ensembles --lib
+```
+
+### Test artifacts not cleaned up
+
+**Cause**: Test panicked before cleanup
+
+**Solution**: Manually clean temp directories:
+```bash
+rm -rf /tmp/tmp.*
+```
+
+## Summary
+
+The g3-ensembles test suite provides comprehensive coverage of:
+- ✅ Core data structures and logic
+- ✅ Configuration validation
+- ✅ Git repository operations
+- ✅ Segment independence
+- ✅ Status tracking and reporting
+- ✅ JSON processing
+- ✅ End-to-end workflow
+
+All tests are automated, fast, and reliable. The test suite ensures that flock mode works correctly across different scenarios and edge cases.

+            REQUIREMENTS:\n{}\n\n\
+            INSTRUCTIONS:\n\
+            1. Analyze the requirements carefully\n\
+            2. Identify {} distinct architectural modules that:\n\
+               - Have minimal overlap and dependencies\n\
+               - Can be developed largely independently\n\
+               - Represent logical architectural boundaries\n\
+               - Could eventually become separate crates or services\n\
+            3. For each module, provide:\n\
+               - A clear module name\n\
+               - The specific requirements that belong to this module\n\
+               - Any dependencies on other modules\n\n\
+            4. Use the final_output tool to provide your partitioning as a JSON array of objects, where each object has:\n\
+               - \"module_name\": string\n\
+               - \"requirements\": string (the requirements text for this module)\n\
+               - \"dependencies\": array of strings (names of other modules this depends on)\n\n\
+            Example format:\n\
+            ```json\n\
+            [\n\
+              {{\n\
+                \"module_name\": \"core-engine\",\n\

-# Anthropic max_tokens Error Fix - Test Plan
-
-## Changes Made
-
-### 1. Fixed Context Window Size Detection
-- **Problem**: Code used hardcoded 200k limit for Anthropic instead of configured max_tokens
-- **Fix**: Modified `determine_context_length()` to check configured max_tokens first before falling back to defaults
-- **Files**: `crates/g3-core/src/lib.rs` lines 923-945, 967-985
-
-### 2. Added Thinning Before Summarization
-- **Problem**: Code attempted summarization even when context window was nearly full
-- **Fix**: Added logic to try thinning first when context usage is between 80-90%
-- **Files**: `crates/g3-core/src/lib.rs` lines 2415-2439
-
-### 3. Added Capacity Checks Before Summarization
-- **Problem**: No validation that sufficient tokens remained for summarization
-- **Fix**: Added capacity checks for all provider types with helpful error messages
-- **Files**: `crates/g3-core/src/lib.rs` lines 2480-2520
-
-### 4. Improved Error Messages
-- **Problem**: Generic errors when summarization failed
-- **Fix**: Specific error messages suggesting `/thinnify` and `/compact` commands
-- **Files**: Multiple locations in summarization logic
-
-### 5. Dynamic Buffer Calculation
-- **Problem**: Fixed 5k buffer regardless of model size
-- **Fix**: Proportional buffer (2.5% of model limit, min 1k, max 10k)
-- **Files**: `crates/g3-core/src/lib.rs` line 2487
-
-## Test Cases
-
-### Test 1: Configured max_tokens Respected
-```toml
-# In g3.toml
-[providers.anthropic]
-api_key = "your-key"
-model = "claude-3-5-sonnet-20241022"
-max_tokens = 50000  # Should use this instead of 200k default
-```
-
-### Test 2: Thinning Before Summarization
-- Fill context to 85% capacity
-- Verify thinning is attempted before summarization
-- Check that summarization is skipped if thinning resolves the issue
-
-### Test 3: Capacity Error Handling
-- Fill context to 98% capacity
-- Verify helpful error message is shown instead of API error
-- Check that `/thinnify` and `/compact` commands are suggested
-
-### Test 4: Provider-Specific Handling
-- Test with different providers (anthropic, databricks, embedded)
-- Verify each uses appropriate capacity checks and buffers
-
-## Expected Behavior
-
-1. **No more max_tokens API errors** from Anthropic when context window is full
-2. **Automatic thinning** when approaching capacity (80-90%)
-3. **Clear error messages** with actionable suggestions when at capacity
-4. **Respect configured limits** instead of hardcoded defaults
-5. **Graceful degradation** with helpful user guidance
-
-## Manual Testing Commands
-
-```bash
-# Test with small max_tokens to trigger the issue quickly
-g3 --chat
-# Then paste large amounts of text to fill context window
-# Verify thinning and error handling work correctly
-```
