Summary

Removes the standalone "Agent Evaluations" list page and its rail nav entry. The per-job detail view stays (it's the target for job links from the agent-detail Evaluations tab), with its breadcrumb repointed off the deleted list route.

Related Issue

Linear ASTD-439 (epic ASTD-360, "Agent evals to experiments").

Changes

  • Delete AgentEvaluationsListRoute.tsx + its test, and the barrel export.
  • Remove the agentEvaluationsList route object (groups/agentRoutes.tsx), the ROUTES.workspace.agentEvaluationsList path (constants/routes.ts), and the getAgentEvaluationsListRoute builder (routes/utils.ts).
  • Remove the rail nav sub-entry Agent Evaluations and the 'agent-evaluations' assistant nav suggestion (+ its test). Drop the now-unused Form icon import and the dead agent_evaluations assistant link template.
  • Keep agentEvaluationDetail + AgentEvaluationDetailRoute; repoint its "Evaluations" breadcrumb from the deleted list route to the agent-detail Evaluations tab (getAgentEvaluationsTabRoute, resolved from the job's agent).
  • WorkspaceSideNav: keep the Agents rail group as a link to the agents list even with no sub-items. Previously it only rendered when it had children, so removing the sole "Agent Evaluations" sub-entry would have dropped the whole Agents entry from the rail when Monitor is disabled. Mirrors the Models group.

Type of Change

  • Code change (feature, bug fix, or refactor)
  • Code change with documentation updates
  • Documentation only
  • Contributor tooling or automation
  • CI, build, or test infrastructure

Quality Gates

  • Existing tests cover changed behavior — justification: removal is covered by the existing nav-suggestion and eval-route suites; the deleted list page's own test is removed with it. No new observable contract is added.
  • Documentation not applicable — justification: no user-facing docs describe this page or the rail entry.

Verification

  • Pull request title follows the repository's Conventional Commit format
  • Every commit includes an appropriate Signed-off-by: trailer
  • uv run pre-commit run -a passes, or any blocked checks are identified below
  • Targeted tests pass, or tests are marked not applicable above
  • No secrets, API keys, or credentials are included

Targeted validation:

  • pnpm --filter nemo-studio-ui run check — lint 0 warnings, tsc --noEmit clean, full Studio suite 2880/2880.
  • Grep confirms no remaining references to getAgentEvaluationsListRoute / ROUTES.workspace.agentEvaluationsList / AgentEvaluationsListRoute.
  • Live against a running platform: the rail no longer shows "Agent Evaluations"; the "Agents" rail link is preserved; the kept job-detail route renders with a breadcrumb that no longer points at the removed list route.
  • uv run pre-commit run -a not run (frontend-only; DCO + merge-conflict + UI typecheck hooks passed on push).

Summary by CodeRabbit

  • Changes
    • Removed the agent evaluation jobs list page and related navigation links.
    • Agent evaluation detail pages remain available.
    • Agents navigation now appears when the feature is installed or still loading.
    • Updated evaluation detail breadcrumbs to link to the relevant agent’s evaluations section when available.

ASTD-439. Delete AgentEvaluationsListRoute + test; remove the
agentEvaluationsList route, its ROUTES path, the getAgentEvaluationsListRoute
builder, the rail nav sub-entry, the 'agent-evaluations' assistant nav
suggestion, and the dead agent_evaluations link template. Keep the per-job
AgentEvaluationDetailRoute and repoint its breadcrumb off the deleted list
route to the agent-detail Evaluations tab.

Also keep the Agents rail group as a link to the agents list even when it has
no sub-items (previously it only rendered when it had children, so removing the
sole 'Agent Evaluations' sub-entry would have dropped the whole Agents entry
from the rail when Monitor is disabled).

📝 Walkthrough

Walkthrough

Studio removes the standalone agent-evaluations list route and navigation entries. The detail breadcrumb now links to the agent-specific evaluations tab when the job includes an agent name. The Agents sidebar link uses plugin visibility.

The removed getAgentEvaluationsListRoute import left a multiline import that
Prettier collapses to one line. Fixes the Web format check.

Addresses CodeRabbit on #1391. useBreadcrumbs({ items }) runs its effect once
on mount, so the 'Evaluations' crumb captured agentName===null and stayed
non-clickable after the job query resolved. Set breadcrumbs from an effect keyed
on [setBreadcrumbs, workspace, agentName, jobName] instead — the codebase's
established pattern for dynamic breadcrumbs (see IntakeDetail Trace/Session
detail views).
