The workflow runner exposed provider adoption, configuration updates, and bulk provider deletion even though runnable workflows reference providers owned by OpenShell/platform bootstrap. Remove that management path as the first reduction toward portable, skill-controlled PR review.

  • Make provider declarations reference-only; reject management: managed, adopt, and provider config before gateway access. Existing management: referenced remains supported.
  • Remove provider reconciliation, ownership labels, SDK update/delete adapters, and obsolete tests. Preserve provider reads, sandbox attachment, direct OIDC, and inference reconciliation for current callers.
  • Remove delete --providers and delete --all. Keep named sandbox deletion and --sandboxes, propagate failures, and continue remaining named deletions after an error.
  • Add command/function/integration dependency audits and a concrete migration order in docs/code-audit.md. Implementation, tests, and fixtures shrink by 1,354 lines net; audit documentation is additional.

Migration: configure and delete providers through upstream OpenShell/bootstrap, then reference their names. Use harness delete NAME, or --sandboxes for a dedicated workspace. This PR does not migrate the reviewer's GitHub credential wiring or remove inference setup; the audit identifies those follow-ups.

Validation:

  • PASS: build, vet, unit tests, golangci-lint (0 issues), actionlint, shell syntax, and diff checks. Static checks refreshed before commit using Go 1.26.7.
  • PASS: offline suite 14/14; local live suite 19/19; Kind integration 11/11 with the expected CI-mode provider-capability skip. Temporary Kind cluster removed and gateway selection restored.
  • Existing local test-driver failure: 9/10 passed; provisioning discovery rejects a registered localhost endpoint because it searches for 127.0.0.1. Its executed sandbox lifecycle checks passed.
  • SKIP: OCP and HyperShell live checks (no KUBECONFIG / HYPERSHELL_SA_ENV supplied), provider-capability checks and live review publication. No review comments posted during validation.

Summary by CodeRabbit

  • New Features

    • Added bulk sandbox deletion with --sandboxes; targeted sandbox deletion remains supported.
    • Added reusable GitHub Actions support for labeled pull-request reviews with isolated execution and uploaded artifacts.
    • Pull-request reviews now run when requests are opened and automatically receive the review label.
  • Changes

    • Provider creation, updates, adoption, and deletion are no longer handled by the application.
    • CLI descriptions and documentation now reflect gateway-managed providers and sandbox-only deletion.
    • Review locations are validated against the current diff before comments are posted.

Reviews paused

It looks like this branch is under active development. To avoid overwhelming you with review comments due to an influx of new commits, CodeRabbit has automatically paused this review. You can configure this behavior by changing the reviews.auto_review.auto_pause_after_reviewed_commits setting.

Use the following commands to manage reviews:

Walkthrough

Harness now treats providers as referenced gateway-owned data. It removes provider reconciliation and provider deletion. Apply verifies provider references, and delete now handles sandbox cleanup only.

Changes

Provider and sandbox workflow

Layer / File(s) Summary
Provider contracts and planning
internal/config/..., internal/plan/..., cmd/plan_test.go, internal/openshell/types.go, internal/openshell/client.go
Provider config and planning now use referenced providers only. Planning reports present and missing providers, and the related API and test fixtures match that model.
OpenShell provider API removal
internal/openshell/sdkclient/..., internal/reconcile/...
Provider update, delete, and reconcile APIs are removed. SDK conversion now exposes identity only, and the provider reconciliation tests are deleted.
Apply provider verification
cmd/apply.go, cmd/apply_service.go, cmd/workflow_apply.go, cmd/workflow_apply_test.go
Apply verifies declared providers, removes provider reconciliation, and rejects unsupported provider-management fields before gateway access.
Sandbox deletion flow
cmd/delete.go, cmd/delete_test.go
Delete now accepts named sandboxes or --sandboxes, deletes sandboxes only, and aggregates failures. Provider deletion paths are removed.
Docs and review automation
README.md, main.go, docs/README.md, .github/workflows/*.yml, scripts/pr-review.sh, examples/github-pr-reviewer/..., internal/status/status.go, test/pr_review_test.go
Docs, CLI text, workflow files, review scripts, and examples now reflect referenced providers, sandbox cleanup, and label-driven PR review setup.

Mark provider creation and deletion as pre-change inventory.

docs/audit-integrations.md presents cleanup_runtime, run_review, and the Vertex test flow as runner-owned provider lifecycle steps. This conflicts with the reference-only contract, which assigns provider provisioning and deletion to upstream bootstrap. Label these passages as historical, or describe named-provider attachment and sandbox-only cleanup instead.

This change replaces the previous behavior of erroring out on a missing referenced provider with silently reporting it as ActionMissing. The previous hard-fail was a critical safety measure, preventing workflows from starting with a misconfigured or incomplete environment. This change regresses that safety, potentially allowing dependent operations to proceed when they should fail fast.

Verified. Missing referenced providers still fail fast during apply: rejects before sandbox creation, and the sandbox verification path checks the references again. is only the read-only plan representation.

This change weakens the agent output validation. A tool call can have a completed status but still have failed (e.g., with a non-zero exit code). The previous check for metadata.exit == 0 was a stronger guarantee of success. Was the removal of this check intentional?

Agreed that non-zero exits must not be ignored generally. The change was intended to tolerate a recoverable GitHub inline-comment location rejection after the agent continues, but the current predicate is too broad. I’m narrowing this to an explicit recoverable marker and adding regression coverage before merge.

This change weakens the test validation by allowing the agent to fail (exit 1) with a "422 Unprocessable Entity" error when posting comments. While this may make the current test pass, it masks an underlying issue and could allow future regressions to go unnoticed. The test should be made more robust, or the underlying issue causing the 422 error should be investigated, rather than weakening the check.

Addressed in 42d1dc1. Ordinary non-zero tool exits remain failures; only an explicit completed GitHub location rejection carrying the 422/location marker is tolerated. Added regression coverage for ordinary failed and missing-exit tool events.

In validate_agent_output, changing the default for a missing exit code from -1 to 0 in the jq filter causes a missing exit code to be treated as a success. This could mask tool execution failures. It would be safer to treat a missing exit code as an error, as the previous // -1 did.

Addressed in 42d1dc1. Missing metadata.exit now defaults to -1 and fails validation; only an explicit zero exit or narrowly identified recoverable 422 location error is accepted.
