From 2b76b7ca8ce987486657bc891b1ee3e4dccfe65a Mon Sep 17 00:00:00 2001 From: Kalin Ovtcharov Date: Wed, 11 Mar 2026 13:22:23 -0700 Subject: [PATCH 01/45] Add chat agent file navigation, write guardrails, and browser tools - Enhanced PathValidator with write guardrails: blocked system directories, sensitive file protection (.env, credentials, keys), size limits (10 MB), overwrite confirmation prompts, timestamped backups, and audit logging - Fixed ChatAgent write_file (had zero security checks) and added edit_file tool - Fixed CodeAgent generic write_file and edit_file (missing PathValidator) - Added FileSystemToolsMixin: browse_directory, tree, find_files, file_info, read_file with smart type detection, bookmarks - Added BrowserToolsMixin: fetch_page, search_web, download_file - Added ScratchpadToolsMixin: SQLite-backed data analysis tables - Added FileSystemIndexService: persistent file index with FTS5 full-text search - Added WebClient: HTTP client with rate limiting and content extraction - Integrated all new tools into ChatAgent with config toggles - 95 unit tests for write guardrails (all passing) --- .github/workflows/test_unit.yml | 14 +- docs/spec/browser-tools.md | 657 ++++++ docs/spec/file-system-agent.md | 2307 +++++++++++++++++++++ setup.py | 4 + src/gaia/agents/chat/agent.py | 200 +- src/gaia/agents/code/tools/file_io.py | 90 +- src/gaia/agents/tools/__init__.py | 10 +- src/gaia/agents/tools/browser_tools.py | 295 +++ src/gaia/agents/tools/file_tools.py | 243 ++- src/gaia/agents/tools/filesystem_tools.py | 1433 +++++++++++++ src/gaia/agents/tools/scratchpad_tools.py | 261 +++ src/gaia/filesystem/__init__.py | 9 + src/gaia/filesystem/categorizer.py | 245 +++ src/gaia/filesystem/index.py | 937 +++++++++ src/gaia/scratchpad/__init__.py | 8 + src/gaia/scratchpad/service.py | 313 +++ src/gaia/security.py | 350 +++- src/gaia/web/__init__.py | 8 + src/gaia/web/client.py | 603 ++++++ tests/unit/test_browser_tools.py | 998 +++++++++ tests/unit/test_categorizer.py | 165 ++ tests/unit/test_chat_agent_integration.py | 291 +++ tests/unit/test_file_write_guardrails.py | 1217 +++++++++++ tests/unit/test_filesystem_index.py | 463 +++++ tests/unit/test_filesystem_tools_mixin.py | 1695 +++++++++++++++ tests/unit/test_scratchpad_service.py | 434 ++++ tests/unit/test_scratchpad_tools_mixin.py | 775 +++++++ tests/unit/test_security_edge_cases.py | 518 +++++ tests/unit/test_service_edge_cases.py | 718 +++++++ tests/unit/test_web_client_edge_cases.py | 718 +++++++ uv.lock | 2 +- 31 files changed, 15913 insertions(+), 68 deletions(-) create mode 100644 docs/spec/browser-tools.md create mode 100644 docs/spec/file-system-agent.md create mode 100644 src/gaia/agents/tools/browser_tools.py create mode 100644 src/gaia/agents/tools/filesystem_tools.py create mode 100644 src/gaia/agents/tools/scratchpad_tools.py create mode 100644 src/gaia/filesystem/__init__.py create mode 100644 src/gaia/filesystem/categorizer.py create mode 100644 src/gaia/filesystem/index.py create mode 100644 src/gaia/scratchpad/__init__.py create mode 100644 src/gaia/scratchpad/service.py create mode 100644 src/gaia/web/__init__.py create mode 100644 src/gaia/web/client.py create mode 100644 tests/unit/test_browser_tools.py create mode 100644 tests/unit/test_categorizer.py create mode 100644 tests/unit/test_chat_agent_integration.py create mode 100644 tests/unit/test_file_write_guardrails.py create mode 100644 tests/unit/test_filesystem_index.py create mode 100644 tests/unit/test_filesystem_tools_mixin.py create mode 100644 tests/unit/test_scratchpad_service.py create mode 100644 tests/unit/test_scratchpad_tools_mixin.py create mode 100644 tests/unit/test_security_edge_cases.py create mode 100644 tests/unit/test_service_edge_cases.py create mode 100644 tests/unit/test_web_client_edge_cases.py diff --git a/.github/workflows/test_unit.yml b/.github/workflows/test_unit.yml index 864ef4300..4b546e9c7 100644 --- a/.github/workflows/test_unit.yml +++ b/.github/workflows/test_unit.yml @@ -43,7 +43,8 @@ jobs: -

Address all 17 open CodeQL code scanning alerts: Python: Add path traversal validation with realpath/symlink checks (EMR server), sanitize API responses to strip stack traces, restrict returned fields from clear_database endpoint, redact URLs in Jira agent logs. JavaScript: Add final path validation in eval webapp server, sanitize redirect URLs to reject protocol-relative paths, add in-memory rate limiters to docs server and dev server, remove identity replacement no-op, add crossorigin attributes to CDN scripts, add HTML sanitizer for XSS prevention in Jira webui, replace innerHTML with safe DOM APIs for user messages.

charset=UTF-8 Content-Transfer-Encoding: 8bit Security fixes: - scratchpad: block multi-statement injection in create_table columns (executescript() DDL path). Validate identifier/type, ban ; -- /* */, require balanced parens. - scratchpad: tokenize keyword filter with word boundaries and strip SQL string literals so SELECTs with columns like email_insert_ts or literals like 'UPDATE PENDING' stop being false-positives. - security.py: apply /private/ macOS symlink normalization to is_write_blocked so /etc/* is actually blocked on Darwin. - security.py: auto-deny allowlist prompt + auto-approve overwrite in non-TTY contexts so the Agent UI / API server don't hang on input(). - security.py: replace bare `except OSError: pass` with log.debug per CLAUDE.md no-silent-fallback rule. - chat-ui.js: expand URL scheme denylist to cover data:/vbscript: and check all URL-bearing attributes (src/action/formaction/xlink:href). Correctness fixes: - filesystem_tools.tree: distinct connector for last vs. intermediate entries so the ASCII tree actually has a shape. - file_tools.edit_file + file_io.edit_file: pass the real size of new_content to validate_write so MAX_WRITE_SIZE_BYTES is enforced. - scratchpad: use its own DB path (~/.gaia/scratchpad.db) instead of colliding with ~/.gaia/file_index.db. - chat/agent.py: gate filesystem/scratchpad/browser prompt blocks by the config flags that already gate their mixin registration. - chat/agent.py: drop stale "web browsing not supported" line and the fetch_webpage typo — the real tools are fetch_page/search_web/ download_file. - chat/agent.py __del__: close FileSystemIndexService and ScratchpadService SQLite connections alongside the web client. - web/client.py: read Content-Type before close(); harden path- traversal guard with os.sep boundary. Tests: - test_yyyy_mm_format: pin mtime to 2026-03-15 via os.utime (was date-sensitive, failed outside March 2026). - Cover _prompt_user_for_access / _prompt_overwrite with _is_interactive patch; add non-interactive regression tests.
