fix(agent): scope nested tool canonical-mode overrides by instance, not type

[waleedlatif1]

Summary

• Fixes a bug where two tool entries of the same type in an Agent block's tool-input array (e.g. two Table tools) shared one canonical-mode override, so switching basic/advanced mode on a field in one instance silently switched it for every other instance of the same tool type
• The override key was ${toolType}:${canonicalId} (shared across every instance of a type); it's now ${toolIndex}:${canonicalId}, scoped to the tool's position in its own tool-input array
• Threaded the tool's array index through every consumer of this key: the editor (tool-input.tsx read + write), execution (agent-handler.ts / providers/utils.ts transformBlockTool), the search index (search-replace/indexer.ts), and fork/promote remapping (dependent-reconfigs.ts)
• This was also a correctness bug at execution time, not just the editor UI — the wrong basic/advanced value could be resolved for the second tool instance when running the workflow

Type of Change

• Bug fix

Testing

• Added a dedicated scopeCanonicalModesForTool test suite in visibility.test.ts covering the instance-scoping behavior directly
• Added a regression test in providers/utils.test.ts with two Table tool instances resolving independent canonical modes
• Added a regression test in dependent-reconfigs.test.ts covering two same-type nested tools in the fork/promote remap path
• Updated existing tests that referenced the old ${toolType}:${canonicalId} key format to the new ${toolIndex}:${canonicalId} format
• Full repo test suite (2864 tests, 175 files) passes; bun run type-check, bun run lint, and bun run check:api-validation all pass

PR Summary

Medium Risk
Changes how canonical modes are keyed and resolved at execution, in realtime persistence, and during fork copy; regression risk is mitigated by broad tests and legacy key fallback.

Overview
Fixes nested tool-input basic/advanced overrides so each tool instance has its own mode instead of sharing one key per tool type.

Override keys move from ${toolType}:${canonicalId} to ${toolIndex}:${canonicalId}. That index is threaded through the editor, transformBlockTool / agent execution, search indexing, and fork/promote remapping. Legacy ${toolType}: keys still work until the user toggles again.

Reindexing keeps overrides aligned when the tools array changes: remove, drag-reorder, and MCP bulk add in tool-input; dropping unresolved custom/MCP tools during fork copy. New helpers reindexToolCanonicalModes / reindexCanonicalModesByPosition produce a full replacement map.

Collaboration adds REPLACE_CANONICAL_MODES (store, socket persistence, permissions) so reindex can atomically replace canonicalModes without stale keys or swap clobbering from per-key merges.

Greptile Summary

This PR scopes nested tool canonical-mode overrides to each tool instance. The main changes are:

• Index-based canonical-mode keys for Agent tool-input entries.
• Reindexing when tools are removed, reordered, or filtered during editor and fork flows.
• Whole-map canonicalModes replacement for collaborative updates.
• Updated execution, search, and fork/remap consumers to pass tool indexes.
• Regression tests for same-type tools, legacy fallback, and stale-key removal.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.

Important Files Changed

Filename	Overview
apps/sim/app/workspace/[workspaceId]/w/[workflowId]/components/panel/components/editor/components/sub-block/components/tool-input/tool-input.tsx	Rekeys tool canonical-mode reads and writes by tool index and reindexes overrides for editor mutations that change tool order or length.
apps/sim/lib/workflows/subblocks/visibility.ts	Adds index-scoped override extraction, legacy fallback handling, and helpers for reindexing or dropping stale tool override keys.
apps/sim/hooks/use-collaborative-workflow.ts	Adds a collaborative operation that replaces the full canonicalModes map instead of merging individual keys.
apps/sim/ee/workspace-forking/lib/remap/remap-references.ts	Threads tool indexes through fork and promote remapping and carries reindexed canonicalModes after dropped nested tools.
apps/sim/executor/handlers/agent/agent-handler.ts	Preserves original tool-input positions across filtering before formatting non-MCP tools for execution.
apps/sim/providers/utils.ts	Resolves canonical resource params from the scoped tool-instance override map.
apps/realtime/src/database/operations.ts	Persists the replace-canonical-modes block operation while preserving other block data.
packages/realtime-protocol/src/constants.ts	Adds the replace-canonical-modes operation constant.
packages/realtime-protocol/src/schemas.ts	Allows the new replace-canonical-modes operation through protocol validation.

Addressed both findings — thanks Greptile and Bugbot, these were real:

1. Legacy ${toolType}: keys silently ignored — scopeCanonicalModesForTool now falls back to the legacy type-scoped prefix when no index-scoped key matches, so an override saved before this fix keeps applying (shared across same-type tools, the old behavior) until the user explicitly re-toggles that specific instance, at which point it's rewritten under the new index-scoped key. No more silent data loss.

2. Index instability on reorder/delete — added reindexToolCanonicalModes (in tool-input/utils.ts, unit tested) and wired it into every mutation site that changes tool order/length in the editor (remove, remove-all-from-server, delete custom tool, drag-reorder, "use all MCP tools"). Diffs old vs. new tool arrays by object identity and re-emits each surviving tool's overrides under its new index before the array mutation is committed.

Pushed as a new commit (rebased + amended). Re-triggering review.
