Greptile Summary

This PR replaces a call to the shared isToolHiddenInUi helper (from lib/copilot/tools/client/hidden-tools.ts) with an inlined HIDDEN_TOOL_NAMES Set and a local isHiddenToolCall function inside message-content.tsx.

• The hidden-tools.ts module is retained and still consumed by four other files (use-chat.ts, store-utils.ts, tool.ts, display-message.ts), creating two independent copies of the same tool-name list.
• Functionally the sets are identical today, but any future update to the shared module won't be reflected in message-content.tsx without a separate manual edit, risking silent leakage of internal tool calls into the rendered UI.

Confidence Score: 3/5

The change introduces a duplicate copy of the hidden-tool list that is no longer tied to the authoritative source, which could cause internal tool calls to appear in the UI if the shared list is updated without a matching edit here.

The inlined HIDDEN_TOOL_NAMES set matches hidden-tools.ts today, but the two lists are now independently maintained. Since hidden-tools.ts is still the active source for four other consumers, a future addition there won't filter in message-content.tsx, silently surfacing implementation-level tool calls in the rendered message UI.

apps/sim/app/workspace/[workspaceId]/home/components/message-content/message-content.tsx — the inlined tool-name set needs to be reconciled with the shared source in lib/copilot/tools/client/hidden-tools.ts.

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/home/components/message-content/message-content.tsx	Removes import of shared isToolHiddenInUi and inlines a duplicate HIDDEN_TOOL_NAMES Set — the shared source in hidden-tools.ts is still used by four other modules, so the two lists can silently diverge.

Duplicated hidden-tool list will silently diverge

hidden-tools.ts still exists and is the authoritative source consumed by use-chat.ts, store-utils.ts, tool.ts, and display-message.ts. By inlining a second copy of HIDDEN_TOOL_NAMES here, any future addition to the shared set (e.g. a new internal tool) won't be picked up by parseBlocks, so those tool calls will leak into the rendered UI while every other consumer filters them correctly. The simpler fix is to restore the import of isToolHiddenInUi from @/lib/copilot/tools/client/hidden-tools.
