After the main agent moved to its own build_main_agent_tools, nothing calls
the shared registry's builders. Delete the dead functions (build_tools,
build_tools_async, get_tool_by_name, get_all_tool_names,
get_default_enabled_tools) plus the now-orphaned load_mcp_tools import and the
stale __init__ re-exports.
BUILTIN_TOOLS, ToolDefinition, and get_connector_gated_tools are retained:
the catalog is still consumed for tool *metadata* (action_log revert/dedup
resolvers and the /agent/tools listing). Also drop stale references to the
deleted chat_deepagent.py within the agents module.
Verified: full unit suite green (2431 passed, 1 skipped); lints clean.
These two tools were "shared-by-folder, not shared-by-use": the only live
consumer of shared/tools/{scrape_webpage,update_memory} was the main agent
(the research/memory subagents carry their own local copies; web_search,
by contrast, is genuinely shared with anonymous_chat and stays put).
Move both into main_agent/tools/ (their sole owner). The shared BUILTIN_TOOLS
catalog still lists them for action_log/revert + /agent/tools, now via
deferred-import factories (_build_scrape_webpage_tool, _build_update_memory_tool)
mirroring the create_automation precedent to avoid a multi_agent_chat import
cycle. Removed the now-dead re-exports from shared/tools/__init__.py.
Verified: full unit suite green (2431 passed, 1 skipped).
After deleting app/agents/new_chat/, several shared-kernel comments still cited
new_chat paths/cycles. Update the two lazy-import comments in middleware to state
the real reason (tools.registry <-> shared.middleware cycle), and repoint dangling
``new_chat/tools/hitl.py`` / ``chat_deepagent`` doc references to their shared
locations. Comment-only; suite unaffected.
Relocate the entire new_chat/tools/ package (62 files incl. registry, hitl, MCP
cluster, and all connector subpackages: gmail/slack/discord/teams/drive/etc.)
to the shared kernel. The package turned out to be a clean cohesive cluster:
its only references to non-tools new_chat modules were comments, and its
middleware deps were already flipped to shared in slice 5c.
Flip 33 live importers (multi-agent, flows, routes, services, anonymous_agent,
tests). Re-export shims remain for the frozen single-agent stack: a package
__init__ mirroring the public surface (new_chat.__init__ imports it) plus
invalid_tool + registry submodule shims (chat_deepagent imports those).
Resolves slice 5c's two transient back-edges: shared/middleware/action_log
(TYPE_CHECKING ToolDefinition) and tool_call_repair (local INVALID_TOOL_NAME)
now point at app.agents.shared.tools.
