- Updated import paths for EditToolDetails across core modules.
- Enhanced patch parsing with unified diff and Codex-style patch support.
- Improved fuzzy matching algorithms for more robust text location.
- Converted SettingsManager.create(), loadSettings(), discoverSkills(), loadSlashCommands(), buildSystemPrompt(), loadSkills(), loadProjectContextFiles(), and getShellConfig() from synchronous to asynchronous APIs.
- Changed capability provider load() method from supporting both sync and async to async-only by removing loadSync().
- Removed fs property from LoadContext interface in capability types.
- Added new fs.ts module with caching layer for filesystem operations using readFile, readDirEntries, readDir, walkUp, and cache management functions.
- Refactored all discovery providers (builtin, claude, cline, codex, cursor, gemini, github, mcp-json, ssh, vscode, windsurf) to use async file operations with Promise.all for parallel loading.
- Removed rulebook tool and migrated rules loading to use read tool instead.
- Reorganized prompt files into subdirectories: agents/, compaction/, and system/.
- Added Handlebars helpers for template rendering including list, join, table, codeblock, xml, when, pluralize, and arithmetic operations.
- Migrated prompt template rendering from simple string replacement to Handlebars-style templating with structured data objects.
- Refactored system prompt generation to pass structured data instead of pre-formatted strings.
- Removed rulebookRules property from ToolSession interface and updated all test files accordingly.
- Added in-memory session storage abstraction with SessionStorage interface and MemorySessionStorage implementation.
- Added configurable bash interceptor rules with pattern-based command interception settings.
- Added AbortSignal support to 80+ web scrapers for request cancellation.
- Changed task tool to require explicit task `id` field and single `agent` parameter at top level.
- Removed `submit_review` tool - reviewers now use `complete` tool with structured output.
- Replaced Date.now() and crypto.randomUUID() with nanoid() for unique ID generation throughout codebase.
- Added `all` parameter to edit tool for replacing all occurrences with fuzzy matching support.
- Added OpenRouter provider support for image generation when `OPENROUTER_API_KEY` is set.
- Renamed image tool from `gemini_image` to `generate_image` with updated default model.
- Added test cases for edit tool's `all: true` option covering multiple scenarios.
Add grep, find, and ls tools for safe code exploration without modification risk.
These tools are available via the new --tools CLI flag.
- grep: Uses ripgrep (auto-downloaded) for fast regex searching. Respects .gitignore,
supports glob filtering, context lines, and hidden files.
- find: Uses fd (auto-downloaded) for fast file finding. Respects .gitignore, supports
glob patterns, and hidden files.
- ls: Lists directory contents with proper sorting and directory indicators.
- --tools flag: Specify available tools (e.g., --tools read,grep,find,ls for read-only mode)
- Dynamic system prompt adapts to selected tools with relevant guidelines
Closes#74
- Add generateDiffString() function in edit tool to create unified diffs with line numbers and 4 lines of context
- Store only the formatted diff string in tool result details instead of full file contents
- Update tool-execution renderer to parse and colorize the diff string
- Filter out message_update events from session saving to prevent verbose session files
- Add markdown nested list and table rendering tests
**Improved output messages:**
1. File fits within limits: Just outputs content (no notices)
2. Lines get truncated: Shows "Some lines were truncated to 2000 characters for display"
3. File doesn't fit limit: Shows "N more lines not shown. Use offset=X to continue reading"
4. Offset beyond file: Shows "Error: Offset X is beyond end of file (N lines total)"
5. Both truncations: Combines both notices with ". " separator
**Comprehensive test coverage:**
- Files within limits (no notices)
- Large files (line truncation)
- Long lines (character truncation)
- Offset parameter
- Limit parameter
- Offset + limit together
- Invalid offset (out of bounds)
- Combined truncations (both notices)
All 17 tests passing ✓
Tool results now use content blocks and can include both text and images.
All providers (Anthropic, Google, OpenAI Completions, OpenAI Responses)
correctly pass images from tool results to LLMs.
- Update ToolResultMessage type to use content blocks
- Add placeholder text for image-only tool results in Google/Anthropic
- OpenAI providers send tool result + follow-up user message with images
- Fix Anthropic JSON parsing for empty tool arguments
- Add comprehensive tests for image-only and text+image tool results
- Update README with tool result content blocks API
