Add autonomous agent infrastructure (M1, M3, M5) by kovtcharov · Pull Request #517 · amd/gaia

kovtcharov · 2026-03-13T22:31:31Z

Summary

M1 Persistent Memory: SharedAgentState singleton with MemoryDB (session-scoped working memory + FTS5) and KnowledgeDB (cross-session insights, credentials, preferences). MemoryMixin provides 8 agent tools and automatic fact extraction after each query. FTS5 uses AND semantics with bm25 ranking and OR fallback. Insight deduplication at >80% word overlap. Confidence decay for stale insights.
M3 Service Integration & Computer Use: WebSearchMixin (Perplexity API + WebClient), ComputerUseMixin (PlaywrightBridge abstraction for learn/replay/list/test browser workflows with self-healing selectors and screenshot capture), ServiceIntegrationMixin (API discovery, encrypted credential management, preference learning via explicit correction and implicit confirmation, decision workflow executor).
M5 Scheduled Autonomy: Async timer-based Scheduler with SQLite persistence, natural language interval parsing ("every 6h", "daily", "30m"), full task lifecycle (create/pause/resume/cancel/delete), REST API at /api/schedules/*, and FastAPI server integration with startup/shutdown lifecycle.

Test plan

274 unit tests passing across 9 test files
Integration tests for live Playwright browser workflows
Integration tests for live Perplexity API (requires API key)
Integration tests for cross-session memory persistence
M2 (Agent UI MCP Server) integration for scheduler MCP tools

- Fix claude.yml release notes job: use direct_prompt instead of prompt for workflow_run event compatibility - Simplify settings.local.json: replace verbose permission allowlist with wildcard mcp__* and switch MCP server to playwright Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…s/webui Move backend and frontend out of the chat-specific namespace to reflect that the UI serves as a general-purpose agent interface, not just chat. Backend: - src/gaia/chat/ui/ → src/gaia/ui/ (server, database, models, sse_handler, tunnel) - Update setup.py package declaration - Update cli.py import and log messages ("Chat UI" → "Agent UI") Frontend: - src/gaia/apps/chat/webui/ → src/gaia/apps/webui/ - Rename bin/gaia-chat.mjs → bin/gaia-ui.mjs Update all references across: - Unit tests, integration tests, Electron tests - Documentation (guides, SDK docs, specs, deployment) - Build scripts (build-chat-installer, release-chat, bump-version) - CI workflows Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Update all user-facing strings, install scripts, test assertions, and frontend components to reflect the GAIA Agent UI identity. Fixes SettingsModal CLI command (gaia chat ui → gaia chat --ui), updates npm package references to @amd-gaia/agent-ui, CLI binary to gaia-ui, and fixes Electron test path for version.py. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Rename scripts: build-chat-installer → build-ui-installer, install-chat → install-ui, bump-chat-version → bump-ui-version, release-chat → release-ui, publish-npm-chat → publish-npm-ui - Update all self-references and docs to use new script names - Fix critical bug: rag.index_file() → rag.index_document() - Fix document IDs not passed to ChatAgent (rag_documents config) - Regenerate root package-lock.json (remove stale @amd-gaia/chat) - Update remaining @amd-gaia/chat → @amd-gaia/agent-ui in docs Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Critical fixes: - build-ui-installer.ps1: Fix path apps/chat/webui → apps/webui - tunnel.py: Make httpx import lazy to prevent ImportError - release-ui.mjs: Fix tag format chat-v* → v* to match CI trigger - publish-npm-ui.yml: Fix concurrency group npm-publish-chat → ui Documentation fixes: - Update all gaia-chat CLI refs → gaia-ui in docs - Update src/gaia/chat/ui/ paths → src/gaia/ui/ in docs + CLAUDE.md - Fix service name gaia-chat-ui → gaia-agent-ui in SDK docs - Fix CORS description to match actual allowlist implementation - Add sse_handler.py and tunnel.py to module structure listing Code improvements: - models.py: Use gaia.version for SystemStatus.version instead of hardcoded 0.1.0 - MessageBubble.tsx: Fix error detection string to match actual backend error messages - Update tests to use dynamic version from gaia.version Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Adds fastapi, uvicorn, httpx, and psutil as installable via pip install -e ".[ui]" so the server can run without manually installing individual packages. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Security: - Fix path prefix attack in PathValidator (project-secrets matched project) API/Server: - Fix SSEOutputHandler missing model_id and streaming parameters (TypeError crash) - Fix missing f-string prefix in app.py stop_server message - Fix None content crash in openai_server.py message preview - Fix Claude provider missing max_tokens default (API requirement) Agents: - Fix rebuild_system_prompt() dropping mixin prompts (use _compose_system_prompt) - Fix progress spinner not stopped on LLM errors (ConnectionError + Exception) - Fix os.makedirs("") crash on bare filenames in file_io.py - Fix update_gaia_md always reporting "updated" (check existence before write) Infrastructure: - Fix truncated Blender MCP responses (single recv → loop) - Fix np.concatenate crash on empty TTS input - Fix double None sentinel in TTS streaming error path - Fix division by zero in eval generators on empty results Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

The streaming test was failing because max_tokens=20 is insufficient when Qwen3 models use thinking/reasoning tokens before producing visible content. Increased token budget to 200, relaxed time assertions for slow CI runners, and made the chunk count assertion handle the case where all tokens are consumed by reasoning.

- Remove unused imports (json in tunnel.py, asyncio in test_tunnel.py) - Add check=False to subprocess.run calls in tunnel.py (pylint W1510) - Apply black formatting to server.py and tunnel.py - Add asyncio_mode="auto" to pyproject.toml for pytest-asyncio support - Update Electron tests to expect 'agent-ui' instead of 'chat' (renamed) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

…arkers The tunnel unit tests used @pytest.mark.asyncio decorators which required pytest-asyncio to be properly configured. CI environments may not have the right asyncio mode configuration. Using asyncio.run() directly makes the tests work without any pytest plugin dependency. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

RAG: - Fix _llm_based_chunking missing f-string prefix (literal {chunk_size} sent to LLM) - Fix nonexistent llm_client.completions() call (should be generate()) Eval: - Fix np.min/np.max crash on empty similarity arrays in eval.py (2 locations) CLI: - Fix 3 division-by-zero bugs in transcript/email/document cost averages - Fix unclosed log_handle in MCP bridge background mode Agents: - Replace deprecated datetime.utcnow() with time.monotonic() in shell_tools.py - Replace deprecated datetime.utcnow() with time.monotonic() in testing.py - Guard rich import in SilentConsole.display_stats() with RICH_AVAILABLE check Infrastructure: - Fix resource leak: store and close log_file in lemonade_client.py terminate_server - Fix SQL injection in database/agent.py db_schema tool (validate table name) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Database: - Fix 4 cursor access outside context manager scope in ui/database.py (delete_session, add_message, delete_document, detach_document) Store rowcount/lastrowid inside the with block before exiting Routing: - Fix unsafe [1] index on ROUTING_ANALYSIS_PROMPT.split() — use [-1] to prevent IndexError if prompt template is modified MCP Bridge: - Fix boundary type confusion: was decoded to str then checked as bytes Simplified to single decode→encode chain Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

- Apply Black formatting to test_chat_sdk.py and security.py - Remove unused pytest import from test_tunnel.py - Suppress pylint unused-argument warning on SSE handler's print_final_answer (parameter is part of interface contract) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
