The test suite was counting shared test support as its own suite and had a couple of narrow unit files that duplicated stronger behavior-level coverage. This cleanup renames the shared config helper out of the *.test.ts glob, removes the redundant catalog and request-metadata suites, and trims presentation assertions to the cases that still add signal.

The catalog defaults and malformed session-metadata cases are preserved at the MCP boundary in the existing open_workspace tests, so the cleanup reduces maintenance without dropping meaningful behavior coverage. There are no production-code changes.

Summary by CodeRabbit

  • Tests
    • Expanded checks for provider availability and configured agent models and effort settings.
    • Added coverage confirming that empty or invalid session metadata does not reuse a workspace.
    • Updated test setup to use shared configuration support across CLI, server, workspace, and package-install tests.
    • Revised local-agent presentation checks and removed several previous catalog and request-metadata test cases.

📝 Walkthrough

Walkthrough

Test files now import the shared configuration helper from config.js, and the build configuration excludes src/test-support files. Server tests expand provider and session assertions. Local-agent presentation tests revise fixtures and assertions. Catalog and request-metadata test coverage is removed.

Changes

Test suite updates

Layer / File(s) Summary
Test support imports and build exclusion
src/bin-launcher.test.ts, src/cli*.test.ts, src/local-agent-profiles.test.ts, src/server-oauth.test.ts, src/skills.test.ts, src/workspace-conversation.test.ts, src/workspaces.test.ts, test/package-install-smoke.test.ts, tsconfig.build.json
These tests now import writeTestDevspaceConfig from config.js instead of config.test.js. The build configuration excludes src/test-support/**/*.
Server provider and session assertions
src/server.test.ts
The provider test checks configured Codex model and effort values, and checks the default and custom Codex agents while excluding the Claude-backed agent. Session tests check workspace separation for empty-string, numeric, and object values. The callOpen helper accepts unknown session values and includes metadata when the value is not undefined.
Local-agent and request-metadata tests
src/local-agent-catalog.test.ts, src/local-agent-presentation.test.ts, src/request-meta.test.ts
Catalog and request-metadata tests are removed. Presentation tests revise receipt and failed-observation assertions, remove summary and completed-observation assertions, and omit the unavailable provider's reason field.

407-418: 🎯 Functional Correctness | 🔵 Trivial | ⚡ Quick win

Cover explicit profile model overrides through open_workspace.

The current test covers only inheritance because reviewer has no model. Add a profile with model: "gpt-custom" and assert that MCP returns that value. Otherwise, replacing an explicit profile model with the provider default would pass this test while returning the wrong catalog data to MCP clients.

Addressed the model-override coverage gap in 67ec898. The open_workspace catalog test now covers both provider-default inheritance and an explicit profile model override, so deleting the narrow catalog unit no longer drops that behavior.

RetriggerConfidence Score: 4/5

[Low risk] Reorganizes test files and removes redundant test cases.

There are no blocking findings; the remaining concerns are unused published test code and three lost regression checks.

Findings

  1. P2 Profile override check disappears ▶
  2. P2 Starting status check disappears ▶
  3. P2 Malformed session checks miss reuse ▶

Summary

Renames the shared config helper out of test discovery, removes two unit suites, and trims presentation tests. No production implementation changes.

  • Adds boundary assertions for catalog defaults and malformed session metadata.
  • The renamed helper now enters production builds and published packages unless its directory is excluded. Building and packing both revisions confirmed the new package content.
  • Three removed checks are not fully replaced: profile model overrides, starting receipts, and malformed-session non-reuse. Controlled changes to these behaviors passed the surviving relevant tests but failed the removed assertions.

These are non-blocking package-content and test-coverage concerns. No current production behavior regression was demonstrated, and there are no blocking findings.

These findings could not be posted inline.

  • P2 Test helper enters published packages src/test-support/config.ts:23 ▶

    Renaming the helper to config.ts also puts it in the production build: tsconfig.build.json excludes *.test.ts, but not src/test-support, and the package publishes dist. Building and packing both revisions confirmed that the helper is absent at base but shipped at head. This is a non-blocking package-content concern: consumers receive unused test-only code. Add src/test-support/**/* to the build exclusions so the helper stays out of published packages.

    Note: If this suggestion doesn't match your team's coding style, reply to this and let me know. I'll remember it for next time!

Cover mixed-provider profile filtering in open_workspace.

The test defines profiles only for codex. A regression that includes profiles from an unavailable configured provider would still pass. Add an unavailable provider with a profile, then assert that agents contains only profiles whose providers are usable.

Restore the focused presentation assertions.

The removed assertions cover distinct outputs used by reachable CLI commands. Restore them to protect receipt normalization, completed summary targets, and completed observation response text from regressions.

Addressed the remaining valid catalog gap in bd743dbf: open_workspace now has a configured-but-unavailable Claude provider/profile and asserts that only usable-provider profiles are advertised.

I did not restore the two completed presentation assertions. Those exact reachable behaviors are already covered at the stronger CLI boundary: agents ls exercises idle → completed plus the profile target, and agents show exercises idle → completed plus latestResponse rendering. The unique starting → running receipt mapping is still covered directly in local-agent-presentation.test.ts.
