Single tool exposed to the main agent. The main agent passes a natural-language
`intent`; a focused drafter sub-LLM turns it into a full AutomationCreate JSON;
that JSON is surfaced via request_approval (action_type "automation_create") so
the user can edit/approve it on a frontend card; on approval the tool persists
via AutomationService. Three phases, one tool call.
Scope split:
- main agent sees only `intent: str` (no schema knowledge leaks into the calling
graph) — prompt fragments scoped accordingly.
- drafter sub-LLM owns the schema + few-shot intent→JSON examples — lives in
the generating graph's prompt (tools/automation/prompt.py).
Files:
- main_agent/tools/automation/{create.py, prompt.py, __init__.py}: new tool
+ drafter system prompt with two few-shot intent→JSON examples.
- system_prompt/prompts/tools/create_automation/{description.md, example.md}:
intent-only guidance for the main agent.
- main_agent/tools/index.py: add create_automation to the main-agent allowlist.
- new_chat/tools/registry.py: deferred-import factory to break the
multi_agent_chat ↔ registry cycle; one ToolDefinition entry.
- Added new environment variables for controlling task execution limits, including `SURFSENSE_SUBAGENT_INVOKE_TIMEOUT_SECONDS`, `SURFSENSE_TASK_BATCH_CONCURRENCY`, and `SURFSENSE_TASK_BATCH_MAX_SIZE`.
- Updated documentation to reflect new batch processing capabilities for `task` calls, allowing for concurrent execution of multiple subagent tasks.
- Improved error handling and receipt generation for deliverables, ensuring consistent feedback on task status.
- Refactored middleware to incorporate search space ID for better task management.
Resolves: surfsense_backend/app/agents/new_chat/middleware/memory_injection.py
- Took both imports: upstream moved MEMORY_HARD_LIMIT/SOFT_LIMIT to
app.services.memory; kept our perf-logger import for timing.
Pulls in upstream changes:
- Memory document feature (services/memory refactor, removal of
app.agents.new_chat.memory_extraction and background extraction in
stream_new_chat — agent now drives memory via update_memory tool).
- BACKEND_URL env refactor across web tool-ui/editor/chat/dashboard/lib.
- GitHub Actions backend test workflow + pre-commit biome bump.
- Token-display polish in MessageInfoDropdown; save_memory no-update
sentinel.
Verified: 1723 unit tests pass, ruff clean. No semantic regression in
stream_new_chat (their memory-extraction deletion and our preflight
removal touch different functions).
Collapse the invalidate + warmup pair into a single
refresh_mcp_tools_cache_for_connector(connector_id, search_space_id)
helper and scope live discovery to the one connector that changed
instead of the whole search space.
- new mcp_tool.discover_single_mcp_connector: load one connector,
refresh OAuth if needed, force live MCP discovery so its cached_tools
row is rewritten; returned wrappers are discarded since the in-process
LRU is rebuilt lazily on the next user query
- mcp_tools_cache.refresh_mcp_tools_cache_for_connector: synchronously
evicts the per-space LRU (LRU keys cannot scope finer) and schedules
the per-connector prefetch via loop.create_task
- routes (OAuth callback, MCP POST, MCP PUT) collapse their two
back-to-back calls into a single refresh call; DELETE handlers keep
using bare invalidate_mcp_tools_cache (nothing to prefetch)
No new automated tests: the new functions are I/O glue (DB + network)
where mocked unit tests would test implementation rather than behavior.
The existing 9 unit tests for the cached_tools data shape are unchanged.
Skip the ~1-3s MCP initialize + list_tools handshake on every cache miss
by reading tool definitions from the connector row we already load. Lazy
populate on first miss, self-heal on corrupt cache, zero schema migration.
The FE permission card needs mcp_connector_id, mcp_server, and
tool_description in the interrupt context to render "Always Allow"
against the right connected account. Thread the tool through the
ask pipeline:
- pack_subagent → build_permission_mw(tools=...) → PermissionMiddleware
(tools_by_name) → request_permission_decision(tool=...) →
build_permission_ask_payload(tool=...) projects card fields out of
BaseTool.
- mcp_tool.py: stdio path now stashes mcp_connector_id in metadata for
parity with the HTTP path.
- Updated the `_forced_rewrite` function to strip whitespace from the extracted text and added a warning log if the response is empty, preventing potential issues with empty rewrites.

- Added a new function `_warm_agent_jit_caches` to pre-warm agent caches at startup, reducing cold invocation costs.
- Updated the `SurfSenseContextSchema` to include per-invocation fields for better state management during agent execution.
- Introduced caching mechanisms in various tools to ensure fresh database sessions are used, improving performance and reliability.
- Enhanced middleware to support new context features and improve error handling during connector and document type discovery.
