Replaces the Azure DevOps PAT used for VS Code Marketplace publishing with short-lived Azure Managed Identity credentials obtained through GitHub Actions OIDC.

Changes

  • Marketplace authentication: Grants publish-marketplace job-scoped id-token: write, signs in through pinned azure/login using repository secrets, and publishes with vsce --azure-credential.
  • Federation boundary: Rejects manual release workflows launched from anything other than main, matching the managed identity's branch-bound federated credential while preserving the existing source ref input for trusted patch releases.
  • Operations documentation: Documents managed identity creation, GitHub federation, Marketplace publisher authorization, secret configuration, rollout verification, and removal of the obsolete Azure PAT secret.
  • Local configuration: Removes the obsolete Azure PAT entry from the VS Code extension environment sample.

Why

Long-lived Azure DevOps PATs create rotation and exposure risk in the release path. Workload identity federation gives each release a short-lived credential without moving publishing away from GitHub Actions or introducing a PAT fallback.

The Marketplace identity has no Azure RBAC assignment; azure/login uses allow-no-subscriptions: true because publishing only needs an Entra token for Marketplace. Open VSX publishing remains unchanged and continues to use OPEN_VSX_ACCESS_TOKEN.

Verification

  • actionlint .github/workflows/release.yml
  • prettier --check .github/workflows/release.yml docs/ci-cd.md
  • git diff --check
  • Confirmed AZURE_DEVOPS_PERSONAL_ACCESS_TOKEN and VSCE_PAT are absent from the release workflow and environment sample
  • Confirmed the Open VSX publishing block is unchanged

External Azure federation, Marketplace membership, and the AZURE_CLIENT_ID and AZURE_TENANT_ID repository secrets must be configured before running the first release.

Review Change Stack

Summary by CodeRabbit

  • CI/CD

    • Marketplace publishing now uses secure Azure OIDC authentication instead of a personal access token.
    • Manual releases are restricted to runs initiated from the main branch.
    • Publishing permissions and Azure authentication are configured automatically during releases.
    • Added a workflow to retrieve and validate the Marketplace identity.
  • Documentation

    • Added setup guidance for Azure managed identity, federated credentials, and repository variables.
    • Updated release permissions and Marketplace authentication instructions.
  • Chores

    • Removed the obsolete Marketplace personal access token from the sample configuration.

Walkthrough

The release workflow now passes the workflow ref to planning and rejects manual releases not launched from main. The marketplace job receives Azure OIDC permissions, logs in with azure/login, and publishes with vsce publish --azure-credential instead of VSCE_PAT. A temporary workflow retrieves and validates the Marketplace identity. The CI/CD documentation describes the Azure managed identity setup, repository variables, federated credential, and removal of the obsolete PAT secret.

Merge Risk: 🟡 Moderate · up to ffbc2

Marketplace publishing now uses Azure OIDC, but the publishing credential remains exposed to dependency installation and patch-branch code. The setup workflow can also fail Azure federation or Profile API calls before the Marketplace identity is retrieved. Resolve these issues before relying on the new release path.

In @.github/workflows/release.yml:
- Line 270: Add an inline YAML comment beside the id-token permission in the
release workflow documenting that azure/login and vsce --azure-credential
require it, resolving the undocumented-permissions warning without changing the
permission value.
- Line 270: Separate VSIX build and test steps from the publish-marketplace job
so dependency installation and lifecycle scripts run without id-token: write.
Have a minimal publishing job consume only the required VSIX artifact, use
pinned actions, and retain OIDC permission solely for Azure authentication after
checkout-free artifact retrieval.

In `@docs/ci-cd.md`:
- Around line 79-81: Update the managed-identity setup guidance in the Azure
publishing instructions to document the tested minimum RBAC scope required for
azure/login subscription discovery, including subscription-level Reader access
with Microsoft.Resources/subscriptions/read or an equivalent custom role. Keep
the separate Marketplace Contributor requirement unchanged.

Also addressed the remaining current CodeRabbit integration note in 610ba82 by adding api-version=7.1 to the documented Azure DevOps Profile API request. Bootstrap-workflow findings are obsolete because that temporary workflow has been removed.
