Add Vite Deno workspace-root detection task to Starter Suite

[Jordak]

Parent

Related to #10.

Current behavior / design

As of this issue being written, the Starter Suite does not include a TypeScript monorepo/tooling task. Vite issue #22237 reports a regression where Vite does not recognize Deno workspace roots when computing server.fs.allow, so nested package roots can exclude repository-level node_modules/.deno paths. No Agent Eval Lab task bundle, reference artifact, reference verification artifact, or Codex smoke trial exists for this candidate yet.

Candidate anchors:

• Repository: https://github.com/vitejs/vite
• Upstream issue: loadAndTransform regression in 8.0.4: consumer === "server"` bypass removed, breaks Deno + nitro vitejs/vite#22237
• Upstream PR: fix: detect Deno workspace root (fix #22237) vitejs/vite#22238
• Start commit: dfc8aa5057dd8ec2b1223980d1e2eeb946ac3384
• Reference commit: 2ea005e5ec4bf2e5c0f4ed5030d84d713f747fac
• Focused upstream test command from the PR: pnpm exec vitest run packages/vite/src/node/server/__tests__/search-root.spec.ts

Why change

The Starter Suite needs more varied realistic tasks before broader capability reporting. This candidate adds TypeScript tooling and monorepo-root detection coverage, which is meaningfully different from the current Python, CLI, UI, setup, and formatter tasks.

What to build

Promote this candidate into a publishable Starter Suite task bundle. The task should ask the agent to make Vite recognize Deno workspace roots declared by a workspace field in deno.json or valid-JSON deno.jsonc, so searchForWorkspaceRoot returns the repository/workspace root instead of a nested package directory.

Keep the task narrow. The grader should exercise searchForWorkspaceRoot behavior directly or through the focused upstream search-root.spec.ts test path; do not require the full Vite test suite, browser tests, or broad end-to-end setup. The expected behavior is that nested and root Deno workspace fixtures resolve to the workspace root when a Deno workspace config is present, while existing package-manager workspace behavior remains intact.

If the task cannot be made fair without full monorepo installation, broad Vite test execution, browser/e2e tests, or unusually slow setup, stop and comment on this issue instead of committing a brittle or resource-heavy task.

Acceptance criteria

• A task bundle exists under the Starter Suite with a stable task id, pinned Vite repository URL, and start commit dfc8aa5057dd8ec2b1223980d1e2eeb946ac3384.
• The prompt describes the Deno workspace-root bug and expected conservative fix without naming the reference commit as the solution.
• Deterministic graders fail on the start commit and pass for the intended fix. They must focus on searchForWorkspaceRoot behavior for deno.json and valid-JSON deno.jsonc workspace configs, preferably through the focused search-root.spec.ts path or an equivalently narrow direct test.
• Graders avoid full Vite test-suite, browser/e2e, or broad monorepo validation.
• Existing workspace-root behavior for non-Deno markers is not broken by the task/reference artifact.
• A reviewed reference artifact is committed and recorded in task.yaml.
• Reference verification passes and writes the standard reference report/result/diff artifacts.
• The generated task-card.md is committed and task-card drift checks pass.
• Run one Codex smoke trial with --trials 1 --jobs 1; if it is fair, comment with the trial/report/result paths. If it is invalid, suspicious, or resource-heavy, comment with the reason and do not scale the trial batch.
• Keep the branch scoped to the task bundle, generated task card, reference artifacts, and task-specific tests if needed; do not add suite README indexes or local task-candidate backlog files.

Closing #41 after pushed resolving commit a1c34ff and passing reference verification plus one Codex smoke trial (20260511-123132-vite-deno-workspace-root-001-codex-ce78d336).

Review found a publishability gap after the smoke run. The pushed task bundle's direct VM grader passes, but the Codex smoke solution added tests for without adding the corresponding fixture files. Because the task does not run the focused upstream path, that broken upstream-test path slipped through. Please tighten the task before treating #41 as complete: either make the grader catch missing fixture references in , run a lightweight focused upstream test path, or adjust the task/reference expectations so accepted solutions cannot leave broken focused tests behind.

[Jordak]

Corrected review note: the gap is that the smoke solution added search-root.spec.ts tests for fixtures/deno-jsonc without adding those fixture files. The current task grader uses a direct VM check and does not run the focused upstream search-root.spec.ts path, so a solution can pass the task while leaving broken focused upstream tests behind. Please tighten #41 before treating it as complete: either add a grader that catches missing fixture references in search-root.spec.ts, run a lightweight focused upstream test path, or adjust the task/reference expectations so accepted solutions cannot leave broken focused tests behind.

Review follow-up implemented and pushed on codex/issue-41-vite-deno-workspace-task.

New commit: 6dda408 (Tighten Vite workspace task graders (#41)).

What changed:

• Added a deterministic grader that reads packages/vite/src/node/server/__tests__/search-root.spec.ts, extracts the focused searchForWorkspaceRoot(resolve(dirname, ...)) expectations, verifies referenced fixture paths exist, and runs those expectations through searchRoot.ts directly.
• Broadened the intent-to-add step to git add -N -- packages/vite/src/node/server/__tests__/fixtures so new focused fixture files, including deno-jsonc fixtures, are included in captured diffs instead of being left untracked.
• Regenerated task-card.md and refreshed reference-report.md / reference-result.json.

Validation:

• python3 .agents/skills/task-card/scripts/render_task_cards.py tasks --check passed.
• python3 -m agentlab task validate tasks passed.
• python3 -m agentlab task verify-reference tasks/starter/vite-deno-workspace-root-001 passed; reference files_changed=5, lines_added=39, lines_deleted=0.
• Commit hook reran task-card drift check and task validation successfully.

Fresh Codex smoke trial:

• Command: python3 -m agentlab task smoke-test --task tasks/starter/vite-deno-workspace-root-001 --agent codex --codex-timeout-seconds 1800
• Trial: 20260511-135357-vite-deno-workspace-root-001-codex-4979b435
• Status: passed
• Report: runs/20260511-135357-vite-deno-workspace-root-001-codex-4979b435/report.md
• Result: runs/20260511-135357-vite-deno-workspace-root-001-codex-4979b435/result.json
• Diff: runs/20260511-135357-vite-deno-workspace-root-001-codex-4979b435/diff.patch

The fresh smoke diff includes all four added Deno fixture files plus search-root.spec.ts and searchRoot.ts, so the previously observed missing-fixture publishability gap is covered.
