📝 WalkthroughWalkthroughThe Responses parser now uses dedicated modules for content, tool, and text-format parsing. The new helpers validate unknown inputs, normalize API-specific shapes, preserve special content, and support independent leaf-module testing. ChangesResponses parser helper extraction
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The parser refactor is mergeable with low risk, but its new tests should more directly pin tool-parameter normalization and supported text-format behavior to prevent future regressions. 🚥 Pre-merge checks | ✅ 4 | ❌ 1❌ Failed checks (1 warning)

📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win
Assert the extracted logic, not only the trivial paths.
The test name promises that the leaf seams "preserve tool and format contracts", but both assertions stop short of the behavior that was extracted.
Line 860 builds a function tool with no parameters. That input exists to exercise normalizeParameters in src/responses/parser-tools.ts (lines 44-47 and 61), which must turn a missing parameters into { type: "object" }. Line 861 asserts only name. If normalizeParameters regressed to return undefined or {}, this test would still pass, because the tool name is unaffected.
Line 862 covers only the !isObj(text) early return at src/responses/parser-text-format.ts line 11. The extracted logic — the json_object branch at line 15 and the json_schema field whitelist at lines 17-23 — has no assertion here.
Add the two assertions that pin the extracted behavior.
💚 Proposed test strengthening
const tools = buildTools([{ type: "function", name: "missing_parameters" }]);
expect(tools?.[0]?.name).toBe("missing_parameters");
+ expect(tools?.[0]?.parameters).toEqual({ type: "object" });
expect(parseTextFormat(undefined)).toBeUndefined();
+ expect(parseTextFormat({ format: { type: "json_object" } })).toEqual({ type: "json_object" });
+ expect(parseTextFormat({ format: { type: "json_schema", name: "s", schema: { type: "object" }, strict: true } }))
+ .toEqual({ type: "json_schema", name: "s", schema: { type: "object" }, strict: true });As per path instructions: "A behavior change in src/ should come with a focused regression test near the existing tests for that subsystem."

Approved for the exact head 3793fb032.
I compared all eleven extracted functions against origin/dev (a594a7f21) with a brace-aware textual check; every body is identical after accounting only for the new export modifier. The public parseRequest import path stays unchanged, the leaves do not import ./parser, the focused parser suite passes 47/47, and TypeScript tsc --noEmit passes under an isolated HOME.
The CodeRabbit test-strengthening comment is non-blocking here: the same test file already has behavior-level coverage for missing-parameter normalization and both json_schema and json_object parsing. This seam test adds the architectural import boundary. Please still wait for the remaining exact-head macOS/keyring checks to finish green before merge; any head change needs incremental review.

Superseded by aggregate PR #3668, admin-merged into dev as 6585e6a after exact-head CI and tested-tree verification. This original PR was not individually merged; its rebased content and historical records were consolidated in #3668. The original branch is preserved. Further unimplemented debt layers remain deferred. |

Summary
src/responses/parser.ts(883 lines) sheds three private helper groups into sibling leaves —parser-content.ts(127: input/output block typing and image-detail normalization),parser-tools.ts(188: tool-choice mapping, tool building, custom namespaces),parser-text-format.ts(24) — leavingparseRequestbyte-identical at its original path (the only export; 560 lines). All 49 importers keep theirresponses/parserpath.parseRequestalone is 464 lines; splitting that function is a behavior-preserving extraction, not a move, and is deliberately out of scope here (recorded asRESOLVABLE_AFTER(design:L1-parse-request-extraction)in the devlog ledger per003_parent_decisions.mdRESIDUAL-FN-01).devlog/_plan/260905_now_split_train/210_responses_parser.md.Stack (S07 responses; merge bottom-up):
