feat(workflows): IDE-style reference viewer for workflows by waleedlatif1 · Pull Request #5854 · simstudioai/sim

waleedlatif1 · 2026-07-22T20:12:03Z

Supersedes #5852 — builds directly on @mzxchandra's branch (both original commits preserved) and layers a cleanup/alignment pass on top. Huge thanks to Chandra for the feature itself: the recursive caller/callee resolver, the cycle/diamond handling, and the modal UI all originate there.

What the feature does

Right-click a workflow in the sidebar → Show references opens a modal with two tabs: Used by (workflows that call it) and Uses (workflows it calls), each a recursive tree whose rows navigate to the referenced workflow. Resolution reads live editor state (draft workflow_blocks), resolves the ACTIVE canonical mode so a dormant basic/advanced value can't mask the live one, marks cycles as leaves, and bounds diamond re-expansion.

Changes on top of #5852

Coverage

Added the third call-edge shape: workflow_input tools inside tool-input sub-blocks (an agent invoking another workflow as a tool) now appear in both trees, with array and JSON-stringified values handled via the shared coerceObjectArray helper. Non-call selector shapes (workflowSelector, trigger workflowIds) are deliberately excluded and documented against remapWorkflowReferencesInSubBlocks.

Auth

The route now authorizes like its /api/workflows/[id]/* siblings via authorizeWorkflowByWorkspacePermission and derives the workspace server-side — proper 404/403 semantics, and the client-supplied workspaceId query param is gone from the contract, hook, and modal.

UX

Restored native cmd/ctrl+click open-in-new-tab on sidebar workflow rows; references stay one right-click away in the context menu.
ReferencesModal mounts on demand per row instead of always-mounted-per-row — removes N idle React Query observers in large workspaces and deletes the prevIsOpen reset machinery, the enabled knob, and the staleTime: 0 workaround (now a named 30s constant).

Design system

Tree rows land on the modal's px-4 text gutter, use --text-icon / --surface-hover tokens and the emcn Workflow icon instead of a hardcoded brand hex.

Hardening / hygiene

Escaped LIKE wildcards in the custom_block_ prefix match; imported MAX_CALL_CHAIN_DEPTH instead of mirroring it; un-exported the internal graph builder; removed dead fallbacks, a duplicate not-found scan, and a redundant row-narrowing map.
Route tests updated for the authz shape (401/404/403/200); resolver tests extended for tool-input edges (18 tests passing).

Verification

bunx vitest run on both test files: 18/18 passing
bun run check:api-validation and :strict: pass (baseline 966→967 for the new route)
biome check clean; tsc clean on all touched files

Adds a "Show references" viewer so you can see how workflows connect: which workflows call a given workflow ("Used by") and which workflows it calls ("Uses"), rendered as recursive, clickable trees. - Opened via Cmd/Ctrl+click on a sidebar workflow row and a "Show references" context-menu item. - Resolves references through both the workflow / workflow_input blocks (reusing isWorkflowBlockType) and published custom blocks (custom_block_* -> source workflow), scoped to the workspace. - Builds the whole workspace reference graph once from live workflow_blocks state; cycle-safe DFS marks A->B->A loops as (cycle) leaves. - Contract-bound GET /api/workflows/[id]/references with workspace-level authz; React Query hook gated to fetch only when the modal opens. - Unit tests for the pure graph/tree logic (cycles, self-refs, dangling drop, custom-block + workflow_input resolution) and route tests (401/400/403/200).

… cache, and graph size Addresses review findings on the reference viewer: - Resolve the workflow-block child via resolveActiveCanonicalValue (the shared SOT) instead of basic-first `||`, so an advanced-mode block whose old basic workflowId value lingers resolves to the active manual value. - Keep self-references (A -> A) and render them as a cycle leaf instead of dropping the edge, matching the cycle-safe viewer's purpose. - Set the references query staleTime to 0 so reopening the always-mounted modal refetches live editor state instead of serving a stale cached graph. - Bound converging paths: a node already expanded elsewhere in the tree is emitted once more as a plain leaf (edge stays visible) rather than re-expanded, so a densely reconverging graph can't grow exponentially.

… with platform conventions - authorize via authorizeWorkflowByWorkspacePermission and derive the workspace server-side (404/403 semantics; drops the client-supplied workspaceId query param from the contract, hook, and modal) - add workflow-tool call edges: workflow_input tools inside tool-input sub-blocks now appear in both trees; non-call selector shapes stay deliberately excluded (documented against remap-internal-ids) - restore native cmd/ctrl+click open-in-new-tab on sidebar workflow rows; references stay reachable from the context menu - mount ReferencesModal on demand per row, deleting the prevIsOpen reset, the enabled knob, and the staleTime-0 workaround (now 30s) - align the tree with design tokens (--text-icon, --surface-hover, px-4 text gutter) and drop the hardcoded brand hex - escape LIKE wildcards in the custom_block_ prefix match; import MAX_CALL_CHAIN_DEPTH instead of mirroring it; remove dead fallbacks, the duplicate not-found scan, and the redundant custom-block row map

- drop the vestigial isOpen prop (conditional mount owns visibility) - unify on the emcn Workflow icon in tree rows - inline the static className and derive nodes without an annotation - remove one restating test comment

PR Summary

Medium Risk
New read API exposes workspace call graphs from draft block data; auth follows existing workflow read checks, but resolver complexity and SQL over subBlocks/tool-input JSON warrant careful review.

Overview
Adds an IDE-style workflow references flow: sidebar context menu Show references opens a modal with Used by and Uses tabs, each a recursive tree; rows navigate to the target workflow. The modal loads via useWorkflowReferences and mounts on demand per row.

Introduces GET /api/workflows/[id]/references with session checks and authorizeWorkflowByWorkspacePermission (read); workspace is derived server-side and getWorkflowReferences returns scoped callers / callees trees. Shared Zod contract (ReferenceNode, recursive schema) wires the route and client.

New resolveWorkflowReferences / getWorkflowReferences build call edges from draft workflow_blocks: workflow / workflow_input blocks (active basic vs advanced workflowId), custom blocks, and agent tool-input workflow tools (including JSON-stringified values and per-tool canonical modes). Trees mark cycles, collapse diamond re-expansion, and cap depth at MAX_CALL_CHAIN_DEPTH. Route and resolver tests cover auth and edge cases; API validation baseline bumps 966→967.

Greptile Summary

This PR adds an IDE-style reference viewer for workflows. The main changes are:

Adds an authenticated API for workspace-scoped workflow references.
Resolves recursive caller and callee trees from live workflow blocks.
Supports direct, custom-block, and tool-input workflow calls.
Adds an on-demand sidebar modal with reference navigation.
Refetches cached reference data whenever the modal reopens.

Confidence Score: 5/5

This looks safe to merge.

The reference query now becomes stale immediately and refetches whenever the modal reopens.
The API applies the established workflow authorization path and server-side workspace scope.
No blocking issues remain in the changed code.

Important Files Changed

…keep the reference cache live - workflow_input tools inside tool-input now resolve basic/advanced via the index-scoped canonicalModes override, mirroring execution (Cursor finding) - staleTime back to 0: no mutation invalidates this key, so a reopen must background-refetch; on-demand mounting keeps the cached tree painting instantly (Greptile P1) - modal header uses the em-dash label-entity convention; tree items carry aria-level instead of a static aria-selected

…ncated expansions - toolInputCallees matches both workflow tool type spellings via isWorkflowBlockType and passes the tool's own type as the legacy canonicalModes fallback, matching providers/utils resolution - a depth-capped expansion no longer poisons the expanded set, so a shallower path re-expands the node in full (Cursor finding) - the allowed-but-workspaceless auth branch now returns 403, not the authz result's 200 - tests: legacy tool type + per-tool index-scope isolation, diamond re-expansion with a real subtree, depth ceiling, shallow-path retry
