Greptile Summary

This PR adds a copilot revert-to-deployment-version tool (executeRevertToVersion) that delegates to the new shared performRevertToVersion orchestration helper, alongside a new set_environment_variables server tool and a companion HTTP route at /api/workflows/[id]/deployments/[version]/revert. It also consolidates the old tool-display-registry.ts display logic into store-utils.ts and ships tests for both new tools.

Confidence Score: 5/5

Safe to merge; all findings are style/guideline violations with no runtime impact.

The core logic — shared performRevertToVersion helper, the new HTTP route, and the set_environment_variables tool — is functionally correct and well-tested. All remaining findings are P2: two crypto.randomUUID() calls that violate the ID utility rule, any types in the env-vars tool, and a vi.importActual() in a test. None of these affect production behavior.

apps/sim/lib/copilot/chat/persisted-message.ts (crypto.randomUUID), apps/sim/lib/copilot/tools/server/user/set-environment-variables.ts (any types)

Important Files Changed

Filename	Overview
apps/sim/app/api/workflows/[id]/deployments/[version]/revert/route.ts	New HTTP POST route for reverting a workflow to a deployment version; correctly handles 'active' and numeric version params and delegates to the shared orchestration helper.
apps/sim/lib/copilot/tools/handlers/deployment/manage.ts	Adds executeRevertToVersion copilot tool handler that delegates to performRevertToVersion; clean implementation with proper access checks.
apps/sim/lib/copilot/tools/server/user/set-environment-variables.ts	New server tool for setting env vars via Mothership; uses any in interface and return type, violating the no-any TypeScript rule.
apps/sim/lib/copilot/chat/persisted-message.ts	Adds normalization and mapping helpers for chat messages; two usages of crypto.randomUUID() violate the project ID generation rule.
apps/sim/lib/copilot/tools/handlers/deployment/manage.test.ts	Tests for executeRevertToVersion; uses vi.importActual() for drizzle-orm, which is forbidden by testing guidelines.
apps/sim/lib/copilot/tools/client/store-utils.ts	Consolidates old tool-display-registry.ts display logic; clean rename with correct imports and tests.
apps/sim/lib/workflows/orchestration/deploy.ts	Adds performRevertToVersion shared helper used by both the HTTP route and the copilot tool; logic is correct and includes audit logging.
apps/sim/lib/environment/utils.ts	Adds upsertPersonalEnvVars and upsertWorkspaceEnvVars helpers with proper encryption, merging, and credential sync.

1. apps/sim/lib/copilot/chat/persisted-message.ts, line 174 (link)

   crypto.randomUUID() instead of generateId()

   The project rule (CLAUDE.md / global.md) prohibits direct use of crypto.randomUUID() and requires generateId() from @/lib/core/utils/uuid — which uses crypto.getRandomValues() and works in non-HTTPS contexts where crypto.randomUUID may be unavailable. The same pattern appears on line 460 as well.

   Add the import at the top of the file: import { generateId } from '@/lib/core/utils/uuid'

2. apps/sim/lib/copilot/chat/persisted-message.ts, line 460 (link)

   Second crypto.randomUUID() usage

   Same rule violation as line 174 — use generateId() instead.
