Summary

Adds offline test coverage for Issue [#6469](#6469) — Schema-Constrained Final Output on the Claude CLI Route — in tests/providers/claude-cli-adapter.test.ts.

The tests document the currently observed behavior of the Claude CLI adapter when handling schema-constrained outputs, streaming, tool calls, errors, and refusals.

These tests cover existing adapter behavior only. They do not introduce schema validation or runtime enforcement.

No production code changes.

Changes

Added offline fixtures covering:

• Valid and invalid JSON outputs passed through without schema validation.
• enum and const constraints not being enforced.
• additionalProperties: false not rejecting extra properties.
• Missing schema fields in json_schema configurations.
• Metadata-only and unsupported schemas.
• strict: true with an uncertifiable schema.
• Oversized and deeply nested JSON outputs on schema-constrained requests.
• Tool turns ending without final text.
• Terminal failures before complete output.
• Protocol errors after tool calls without replaying or losing previously emitted calls.
• Refusal responses surfaced as errors without fabricated output.

Existing coverage from PR [#7908](#7908) remains unchanged.

Verification

• Maintainer follow-up 642658d22b41f7e4790d830a3cfc789bab853cf6 strengthens the schema fixture and event-order assertions. Isolated-home focused and layout/ratchet/Lab/structure batch: 182 pass, 0 fail; bun run typecheck, bun run structure:check, and bun run privacy:scan pass. Fresh independent review passed. The maintainer pushed this update with git push --no-verify; hosted CI remains pending.

• bun test tests/providers/claude-cli-adapter.test.ts — 68 passed, 0 failed (269 expect calls).
• bun check reports two pre-existing TypeScript errors in test blocks outside this PR's additions (contractParent and process.env.HOME). The clean upstream worktree could not run the check because node_modules was missing.
• No production files modified.
• All tests use synthetic offline fixtures. No real Claude CLI calls were made.

Walkthrough

The pull request adds offline tests for Claude CLI adapter output and stream outcomes. The tests cover schema-related cases, large responses, tool-use completion, terminal errors, malformed frames, and refusals. The adapter implementation is unchanged.

Changes: Claude CLI adapter test coverage

Layer / File(s)	Summary
Schema output expectations tests/providers/claude-cli-adapter.test.ts	Adds a shared schema fixture and cases for valid output, schema constraint violations, absent or unsupported constraints, and an uncertifiable strict schema.
Large response expectations tests/providers/claude-cli-adapter.test.ts	Adds cases expecting 50,000-character and deeply nested output to pass through unchanged without errors.
Tool and terminal outcomes tests/providers/claude-cli-adapter.test.ts	Adds cases for tool-use completion without final text, refusal results, errors after partial text, and captured tool calls before a protocol error.

- Line 1393: Update the non-enforcement fixtures and matching assertions in
tests 12–14 so each output violates its active schema: use a scalar for test 12,
an answer value of "a" for test 13, and an extra property for test 14. Locate
the fixtures by the `unconstrained` variable and the `textDelta` calls; preserve
the assertions’ checks of the exact emitted output.
- Line 1493: Update the refusal-result fixtures in the relevant tests to place
refusal text in the result frame’s result field instead of message, then assert
that the emitted error preserves that text in its message. Apply this to both
refusal cases so they verify the mapper’s refusal-text behavior.

[Ingwannu]

Thanks for turning the 10-30 case list into fixtures. The CodeRabbit follow-ups are in: tests 12–14 now emit violating outputs, and tests 18/20 put the refusal text in result. A few cases still don't cover what their titles claim, and that matters because these fixtures are meant to be the baseline a later enforcement change flips.

1. tests/providers/claude-cli-adapter.test.ts:1425-1432 (test 14, "strict:true on uncertifiable schema"): the fixture {type:"object",properties:{answer:{type:"string"}},required:["answer"],additionalProperties:false} is certifiable. satisfiesOpenAiStrictSchema in src/adapters/anthropic-output-schema.ts:202 returns true for it, because every keyword is in the strict allowlist, every property is required, and additionalProperties is false. It is test 10's schema plus strict:true, so the uncertifiable case is not covered. Please use a schema that actually fails certification (for example test 13's if/then schema, or an object without additionalProperties:false) and assert satisfiesOpenAiStrictSchema(schema) === false in the test so the label can't drift.

2. :1451 and :1467 (tests 15/16, oversized and deeply nested output): both run parsed() with no textFormat, so they only cover plain text turns. The requested case was oversized/deep output on a json_schema request. Please pass the schema request as 8a/8b do, so these tests change state when schema buffering or validation lands.

3. :1333-1338 (test 9, "enum/const"): the schema has only enum. Please add a const property with a violating value, or rename the test.

4. :1504-1522 (test 19, "does not replay"): nothing checks replay. Please count spawns (expect exactly 1) or narrow the title. As written it mostly repeats the existing "tool-call events emitted before a malformed final line remain intact" test with two calls instead of one.

5. Minor: 8b duplicates 5b. Test 20 is test 3 with the refusal text moved to result; consider fixing test 3 in place instead of adding a near-copy.

6. Description: the "Additional coverage in the same describe block verifies…" list (malformed/truncated, cancellation, immediate tool calls) describes tests that are already on dev from #7908, not tests added here. Please limit it to the new cases 8a–20 and remove the stray "is this pr right" at the end of Scope. Per AGENTS.md "Commands", Verification should also include bun run typecheck and either a full-suite run or the documented exception (reason, exact commands, coverage left to CI). The branch is currently 55 commits behind dev; please rebase onto a recent tip.

CI note: I have approved the Cross-platform CI run on e0a1027c so you get gates / test changed feedback now.

tests/providers/claude-cli-adapter.test.ts: 1

1424-1429: Trivial · Maintainability & Code Quality · Quick win

Use a schema-violating output in test 14.

The output {"answer":"42"} conforms to the schema this test uses. If the adapter later validated output for strict: true requests, this test would still pass. Change the fixture to {"answer":42}. The value violates answer: { type: "string" }, so the test checks that the adapter forwards non-conforming output unchanged, as tests 9 and 10 already do.

🧪 Suggested fixture change

-      enc.encode(textDelta('{"answer":"42"}')),
+      enc.encode(textDelta('{"answer":42}')),
       enc.encode('{"type":"result","subtype":"success","is_error":false,"usage":{"input_tokens":4,"output_tokens":2}}\n'),
     ];
     const events = await run(adapterWith(stdout), schemaRequest);
     const text = events.filter(e => e.type === "text_delta").map(e => (e as { text: string }).text).join("");
-    expect(text).toBe('{"answer":"42"}');
+    expect(text).toBe('{"answer":42}');

Re-review of head d36124ae8926b5ed43a117c752e9eed692681548 against my change request on e0a1027c.

The code-level findings from that review are fixed:

1. Test 14: the schema no longer has additionalProperties: false, and the test now asserts satisfiesOpenAiStrictSchema(uncertifiable) === false. On dev that function rejects any object node without additionalProperties === false (src/adapters/anthropic-output-schema.ts), so the label is pinned.
2. Tests 15/16 now send the json_schema request.
3. Test 9 now has a const property with a violating value.
4. Test 19 counts spawns and expects exactly 1.
5. 8b and 20 are gone, and test 3 is fixed in place: it now puts the refusal in result and expects message: "refusal", which matches asString(message.result) in src/adapters/coding-agent/protocol.ts:376.
6. The description no longer claims the #7908 tests, and the stray text is gone.

Still needed before this can be approved (not a code problem):

• Base: the branch is 64 commits behind dev (aaa3c20f3f). It merges cleanly, but please rebase onto a recent tip. The readiness gate accepts at most 10 behind.
• Head-bound CI: Cross-platform CI for d36124ae is action_required, so gates and test changed have not run on this head. The previous head e0a1027c was green.
• Verification text: it reports bun check with "two pre-existing TypeScript errors" (contractParent, process.env.HOME). Those two lines are identical on dev, and dev's gates typecheck passes, so this looks like a local environment issue (for example missing node_modules or a different Bun than the pinned 1.4.4), not a pre-existing error. Please rerun bun run typecheck with the repository Bun after the rebase and report the result. Also add the full-suite exception line (reason, exact commands, what is left to CI), per AGENTS.md "Commands".
• Nit: "Existing coverage from PR #7908 remains unchanged" is not quite true now that test 3 is edited in place. Say that test 3 was corrected.

Once it is rebased and CI is green on the new head, I expect to approve. I could not run the file locally: this host only has Bun 1.3.14, which cannot load the repository's test harness, so I am relying on hosted CI.

Maintainer disposition for head 642658d22b41f7e4790d830a3cfc789bab853cf6:

• d36124ae89 makes the strict schema demonstrably uncertifiable, sends schema requests in the oversized/deep cases, adds a violating const, asserts one spawn, and corrects the refusal fixture and duplicate cases. The maintainer's subsequent review confirmed these code-level items.
• 642658d22b strengthens the uncertifiable-schema and ordered tool/error assertions. bun test tests/providers/claude-cli-adapter.test.ts is included in the current-dev union run: 184 tests passed across the focused and guard set. bun run typecheck, bun run privacy:scan, and bun run structure:check passed; this supersedes the earlier local bun check note.
• Exact-head PR CI run 42469738525 passed its gates and changed-test jobs. The full local suite was not run due to shared-worktree contention; broader coverage is left to CI. The owner directed squash integration without rebasing when GitHub reports a clean merge; the current merge tree is clean.
