From 426e50602154b915a67ebe9fffcbdc6fe4eeb256 Mon Sep 17 00:00:00 2001 From: Y1fe1Zh0u Date: Fri, 24 Jul 2026 14:28:36 +0800 Subject: [PATCH 1/6] Let group runs reuse ordinary workspace tools Group workspace files now share the ordinary file-tool surface through an explicit workspace scope, while the four group business tools remain unchanged. Legacy group workspace names stay execution-compatible for in-flight checkpoints but are removed from new model contracts. Document reads reuse the existing binary parser and mutations retain durable fencing and reconciliation. Constraint: Group storage authorization and mutation receipts remain separate from private Agent Workspace storage. Rejected: Expose a second generation of group-specific file tools | it repeats the namespace-selection failure and still leaves write/edit parity unresolved. Confidence: high Scope-risk: moderate Reversibility: clean Directive: Do not add Group Workspace move_file until source deletion and target creation can be reconciled as one durable operation. Tested: 2057 backend tests; focused group runtime, model step, tool step, reconciler, builtin contract tests; Ruff; py_compile; diff check. Not-tested: Live 3010 group chat flow before deployment; real S3/Cloudflare document parsing path. --- .../agent_runtime/group_runtime_tools.py | 509 +++++++++++++++++- .../agent_runtime/model_step_service.py | 2 +- .../agent_runtime/product_reconciler.py | 22 +- .../agent_runtime/tool_step_service.py | 75 ++- backend/app/services/agent_tools.py | 46 ++ .../app/services/builtin_tool_definitions.py | 88 +-- .../tests/test_agent_runtime_group_tools.py | 326 ++++++++++- .../test_agent_runtime_model_step_service.py | 23 +- .../test_agent_runtime_product_reconciler.py | 8 + .../test_agent_runtime_tool_step_service.py | 102 ++++ backend/tests/test_builtin_tool_contracts.py | 16 +- 11 files changed, 1097 insertions(+), 120 deletions(-) diff --git a/backend/app/services/agent_runtime/group_runtime_tools.py b/backend/app/services/agent_runtime/group_runtime_tools.py index 43682a077..cd6e5cfe9 100644 --- a/backend/app/services/agent_runtime/group_runtime_tools.py +++ b/backend/app/services/agent_runtime/group_runtime_tools.py @@ -4,8 +4,11 @@ from collections.abc import Mapping, Sequence from copy import deepcopy +import fnmatch import hashlib import json +from pathlib import Path +import re import uuid from sqlalchemy import select @@ -16,6 +19,7 @@ from app.models.participant import Participant from app.models.user import User from app.services import group_chat_service, group_file_service +from app.services.agent_tools import _read_file_binary_error, read_document_bytes from app.services.agent_runtime.command_worker import RuntimeSessionFactory from app.services.agent_runtime.state import RuntimeContext, RuntimeGraphState from app.services.agent_runtime.tool_execution import ( @@ -37,44 +41,68 @@ GROUP_WRITE_WORKSPACE_FILE = "group_write_workspace_file" GROUP_DELETE_WORKSPACE_FILE = "group_delete_workspace_file" -GROUP_READ_TOOL_NAMES = frozenset( +GROUP_BUSINESS_READ_TOOL_NAMES = frozenset( { GROUP_QUERY_MEMBERS, GROUP_READ_ANNOUNCEMENT, GROUP_READ_MEMORY, - GROUP_LIST_WORKSPACE, - GROUP_READ_WORKSPACE_FILE, } ) -GROUP_WRITE_TOOL_NAMES = frozenset( +GROUP_BUSINESS_WRITE_TOOL_NAMES = frozenset({GROUP_WRITE_MEMORY}) +GROUP_BUSINESS_TOOL_NAMES = ( + GROUP_BUSINESS_READ_TOOL_NAMES | GROUP_BUSINESS_WRITE_TOOL_NAMES +) +GROUP_SCOPED_WORKSPACE_TOOL_NAMES = frozenset( { - GROUP_WRITE_MEMORY, + GROUP_LIST_WORKSPACE, + GROUP_READ_WORKSPACE_FILE, GROUP_WRITE_WORKSPACE_FILE, GROUP_DELETE_WORKSPACE_FILE, } ) +GROUP_READ_TOOL_NAMES = GROUP_BUSINESS_READ_TOOL_NAMES | frozenset( + {GROUP_LIST_WORKSPACE, GROUP_READ_WORKSPACE_FILE} +) +GROUP_WRITE_TOOL_NAMES = GROUP_BUSINESS_WRITE_TOOL_NAMES | frozenset( + {GROUP_WRITE_WORKSPACE_FILE, GROUP_DELETE_WORKSPACE_FILE} +) GROUP_WORKSPACE_MUTATION_TOOL_NAMES = frozenset( {GROUP_WRITE_WORKSPACE_FILE, GROUP_DELETE_WORKSPACE_FILE} ) GROUP_TOOL_NAMES = GROUP_READ_TOOL_NAMES | GROUP_WRITE_TOOL_NAMES -_AGENT_WORKSPACE_TOOL_NAMES = frozenset( +SCOPED_WORKSPACE_TOOL_NAMES = frozenset( { "list_files", "read_file", + "read_document", "search_files", "find_files", "write_file", "edit_file", - "move_file", "delete_file", } ) -_AGENT_WORKSPACE_GROUP_SCOPE_NOTE = ( - "Group scope note: this tool accesses the Agent's own Workspace, not the " - "current Group Workspace.

compound cursor, not bare timestamp The agent chat view derived its "before" pagination cursor from `messages[0].created_at` alone, dropping the `|id` component. The backend's `before` contract is `|`, and it already returns a ready-to-use `cursor` field per message. When a single turn persists a batch of messages that share one `created_at` (e.g. a burst of tool_call rows) and that batch is larger than HISTORY_PAGE_SIZE, the timestamp-only cursor never advances: the backend's legacy-cursor fallback pins the id to the max UUID, so every page re-returns the same equal-timestamp rows. Pagination loops, inflating the tool count on each scroll, and any message older than the batch (including the user's first message) can never be loaded. Round-trip the backend `cursor` field at all four cursor-set sites, falling back to `created_at` only when absent.

Shorten only the revision identifier before retrying the untouched migration.
