# Plan: AI Loop Regressions (MiniMax, Gemini, Gemini CLI, DeepSeek)
|
||||
|
||||
**Track:** `ai_loop_regressions_20260614`
|
||||
**Spec:** `spec.md`
|
||||
**Status:** Active (plan approved 2026-06-14)
|
||||
|
||||
## TDD Protocol (MANDATORY)
|
||||
|
||||
For each phase, the order is:
|
||||
1. **Red**: write the failing test (TDD red phase).
|
||||
2. **Verify red**: run the test; confirm it fails for the right reason.
|
||||
3. **Green**: implement the fix; run the test; confirm it passes.
|
||||
4. **Verify green**: run the full suite to confirm no regression.
|
||||
5. **Commit**: one atomic commit per task with a clear message.
|
||||
|
||||
Per the project rule (see `AGENTS.md` "Critical Anti-Patterns"), the test file must be created BEFORE the implementation. The 1-space indentation rule is in effect (see `conductor/product-guidelines.md` "AI-Optimized Compact Style").
|
||||
|
||||
---
|
||||
|
||||
## Phase 1: Root-Cause Verification (TDD Red)
|
||||
|
||||
**Focus:** Write 3 sets of failing tests that reproduce the 3 bugs. Each test must fail for the documented reason (not a typo or import error). All tests committed in separate atomic commits so Tier 2 can verify red → green for each one.
|
||||
|
||||
- [ ] **Task 1.1**: Create `tests/test_ai_loop_regressions_20260614.py` with the FR1 test scaffold
|
||||
- **WHERE:** `tests/test_ai_loop_regressions_20260614.py` (new file)
|
||||
- **WHAT:** Add the 3 FR1 tests (mock `ai_client.send` to return `""`, then assert that `event_queue.put("response", ...)` was called with `status="error"` and the error message in the text). Use 1-space indentation. Use existing test fixtures from `tests/conftest.py` (e.g., `mock_app` for the controller, `vlogger` for log capture).
|
||||
- **HOW:** Mock `ai_client.send_result` to return `Result(data="", errors=[ErrorInfo(kind=ErrorKind.NETWORK, message="connection refused")])`. Call `controller._handle_request_event(event)`. Assert that the event queue received a `response` entry with `status="error"` and `text` containing "connection refused". Assert that `_ai_status` is `f"error: {ui_message}"`.
|
||||
- **SAFETY:** Do not make real network calls; use mocks. The event queue is lock-protected; ensure the test drains it before asserting.
|
||||
- **VERIFY:** `uv run pytest tests/test_ai_loop_regressions_20260614.py::test_fr1_error_becomes_discussion_entry` — should FAIL with `AssertionError` (current code puts `status="done"` not `status="error"`).
|
||||
- **COMMIT:** `test(ai_loop): add FR1 tests for error-becomes-discussion-entry (TDD red)`
|
||||
|
||||
- [ ] **Task 1.2**: Add the FR2 test scaffold
|
||||
- **WHERE:** `tests/test_ai_loop_regressions_20260614.py` (append to existing file)
|
||||
- **WHAT:** Add 2 FR2 tests. (a) `test_fr2_no_provider_error_in_source` — walks the AST of `src/app_controller.py` and asserts no `ProviderError` references exist (uses `ast` module). (b) `test_fr2_api_endpoint_handles_send_result_error` — calls the `/api/v1/generate` endpoint with a mock that returns `Result(data="", errors=[...])` and asserts it returns a 502 with the error message in the detail field.
|
||||
- **HOW:** For (a), use `ast.walk` on `ast.parse(open("src/app_controller.py").read())` and look for `ast.Attribute` nodes where `attr == "ProviderError"`. For (b), use `httpx.AsyncClient` or `requests` with the running FastAPI app, or test the function directly.
|
||||
- **SAFETY:** AST scan is read-only; no side effects.
|
||||
- **VERIFY:** `uv run pytest tests/test_ai_loop_regressions_20260614.py::test_fr2_no_provider_error_in_source` — should FAIL with `AssertionError` (3 references currently exist at lines 305, 313, 3692).
|
||||
- **COMMIT:** `test(ai_loop): add FR2 tests for dead ProviderError clause removal (TDD red)`
|
||||
|
||||
- [ ] **Task 1.3**: Add the FR3 test scaffold
|
||||
- **WHERE:** `tests/test_ai_loop_regressions_20260614.py` (append to existing file)
|
||||
- **WHAT:** Add 2 FR3 tests. (a) `test_fr3_minimax_thinking_in_returned_text` — mocks `_send_minimax`'s `_minimax_client` to return a `NormalizedResponse` with `text="actual response"` and `reasoning_details=[{"text": "thinking content"}]`. Calls `ai_client._send_minimax(...)` and asserts `result.data` contains `<thinking>thinking content</thinking>`. (b) `test_fr3_minimax_thinking_parsed_by_thinking_parser` — calls `thinking_parser.parse_thinking_trace(result.data)` and asserts 1 segment is found with the expected content.
|
||||
- **HOW:** Use `unittest.mock.MagicMock` to construct a fake `OpenAI`-compatible client that returns a `ChatCompletion` object with the reasoning_details attribute. See `tests/test_deepseek_provider.py:test_deepseek_reasoner_payload_verification` for the existing mock pattern.
|
||||
- **SAFETY:** No network calls. The mock's reasoning_details attribute is a list of dicts; the extractor in `_send_minimax` accesses `choice.message.reasoning_details[0].get("text", "")`.
|
||||
- **VERIFY:** `uv run pytest tests/test_ai_loop_regressions_20260614.py::test_fr3_minimax_thinking_in_returned_text` — should FAIL with `AssertionError` (current `_send_minimax` doesn't include thinking tags in `result.data`).
|
||||
- **COMMIT:** `test(ai_loop): add FR3 tests for MiniMax thinking-mono rendering (TDD red)`
|
||||
|
||||
- [ ] **Task 1.4**: Verify all 3 test groups fail for the right reason
|
||||
- **Command:** `uv run pytest tests/test_ai_loop_regressions_20260614.py -v 2>&1 | tee tests/artifacts/ai_loop_regressions_phase1_red.log`
|
||||
- **EXPECTED:** 7+ tests, all FAILING with the documented reasons (not import errors, not syntax errors, not missing fixtures).
|
||||
- **ACTION:** If any test fails for the WRONG reason (e.g., `ImportError`, `SyntaxError`, missing fixture), fix the test and re-run before proceeding. Do NOT proceed to Phase 2 with a test that doesn't fail for the documented reason.
|
||||
- **COMMIT:** No new commit; this is a verification step.
|
||||
|
||||
---
|
||||
|
||||
## Phase 2: Fix FR1 (Bug #2 — Error Response Becomes a Discussion Entry)
|
||||
|
||||
**Focus:** Update `_handle_request_event` in `src/app_controller.py:3677-3697` to call `send_result()` and route errors to the discussion panel. The streaming path is preserved.
|
||||
|
||||
- [ ] **Task 2.1**: Update `_handle_request_event` to use `send_result()` and route errors
|
||||
- **WHERE:** `src/app_controller.py:3677-3697` (the `_handle_request_event` method's `try` block)
|
||||
- **WHAT:** Replace `ai_client.send(...)` with `ai_client.send_result(...)`. Branch on `result.ok`:
|
||||
- If `result.ok`: existing path — `event_queue.put("response", {"text": result.data, "status": "done", "role": "AI"})` + `_ai_status = "done"`.
|
||||
- If `not result.ok`: route the error — pick the highest-severity `ErrorInfo` (first in `result.errors`), build `ui_message = err.ui_message()` (or just `err.message` if `ui_message()` doesn't exist on the dataclass — check `src/result_types.py` for the actual method name; if not present, use a string format like `f"[{err.kind.name}] {err.message}"`), then `event_queue.put("response", {"text": ui_message, "status": "error", "role": "Vendor API"})` + `_ai_status = f"error: {ui_message}"`.
|
||||
- **HOW:** Use `manual-slop_edit_file` with `old_string` and `new_string`. Preserve the 1-space indentation. Preserve the streaming behavior — the `stream_callback=lambda text: self._on_ai_stream(text)` is unchanged; the fix only changes the final return-value handling.
|
||||
- **SAFETY:** The `_pending_history_adds_lock` in `_on_comms_entry` is unchanged. The thread safety is preserved (the streaming callback runs on the AI client thread; the final result handling runs on the same thread that called `send_result`).
|
||||
- **REFERENCES:** See `docs/guide_ai_client.md` "Data-Oriented Error Handling > Public API > `send_result()` migration" for the canonical call shape; see `conductor/code_styleguides/error_handling.md` §3.1 for the Result-handling pattern.
|
||||
- **VERIFY:** `uv run pytest tests/test_ai_loop_regressions_20260614.py::test_fr1_error_becomes_discussion_entry tests/test_ai_loop_regressions_20260614.py::test_fr1_success_still_works tests/test_ai_loop_regressions_20260614.py::test_fr1_ai_status_updated` — should now PASS.
|
||||
- **COMMIT:** `fix(ai_loop): route send_result() errors to Discussion Hub as error entries (FR1, Bug #2)`
|
||||
|
||||
- [ ] **Task 2.2**: Add a live_gui regression test for the error path
|
||||
- **WHERE:** `tests/test_live_gui_ai_loop_error_path.py` (new file; small, ~50 lines)
|
||||
- **WHAT:** A `live_gui`-fixture test that mocks `ai_client.send_result` to return an error result, then triggers a Gen+Send via `client.push_event("custom_callback", {"callback": "_handle_generate_send", "args": []})`, and polls `get_value("disc_entries")` until the last entry is an `error` entry with the expected text.
|
||||
- **HOW:** Use the `live_gui` session-scoped fixture from `tests/conftest.py`. The `ApiHookClient.push_event` method is used to trigger the Gen+Send flow. The poll pattern is the standard `for _ in range(20): ... if client.get_value("disc_entries")[-1].get("status") == "error": break; time.sleep(0.5)` (max 10s).
|
||||
- **SAFETY:** Use `monkeypatch` to inject the mock; do not modify `ai_client.send_result` directly. Do not pollute other tests' state.
|
||||
- **VERIFY:** `uv run pytest tests/test_live_gui_ai_loop_error_path.py` — should PASS.
|
||||
- **COMMIT:** `test(ai_loop): add live_gui test for error-becomes-discussion-entry (FR1 verification)`
|
||||
|
||||
- [ ] **Task 2.3**: Verify no regression in other providers
|
||||
- **Command:** `uv run pytest tests/test_deepseek_provider.py tests/test_ai_client_cli.py tests/test_gemini_cli_integration.py tests/test_gemini_cli_adapter.py 2>&1 | tee tests/artifacts/ai_loop_regressions_phase2_sweep.log`
|
||||
- **EXPECTED:** All existing tests still pass; no new failures.
|
||||
- **ACTION:** If any test fails, STOP and report to the user. Do not attempt a 3rd fix without the user's direction (per AGENTS.md "Process Anti-Patterns #1 — The Deduction Loop").
|
||||
- **COMMIT:** No new commit; this is a verification step.
|
||||
|
||||
---
|
||||
|
||||
## Phase 3: Fix FR2 (Bug #1 — Replace Dead `except ProviderError` Clauses)
|
||||
|
||||
**Focus:** Remove the 3 dead `except ai_client.ProviderError` clauses in `src/app_controller.py:305, 313, 3692`. Replace with the new `send_result()` + `if not result.ok:` pattern (approach B per user direction).
|
||||
|
||||
- [ ] **Task 3.1**: Replace the 3 sites in `src/app_controller.py`
|
||||
- **WHERE:** `src/app_controller.py:305` (in `_api_generate` for `/api/v1/generate` endpoint), `src/app_controller.py:313` (in `_api_generate_sync` for `/api/v1/generate_sync` endpoint), `src/app_controller.py:3692` (in `_handle_request_event` — but this is the SAME site as Task 2.1; the Phase 2 fix already routes the error correctly, so the Phase 3 work for this site is a no-op or a comment update only).
|
||||
- **WHAT:** For sites 305 and 313: change the call to `ai_client.send_result(...)`, branch on `result.ok`:
|
||||
- If `not result.ok`: `raise HTTPException(status_code=502, detail=err.ui_message())` for the API error response.
|
||||
- Else: existing return path.
|
||||
- For site 3692: this was already replaced in Task 2.1; the Phase 3 work is a docstring update to reference the data-oriented error handling styleguide.
|
||||
- **HOW:** Use `manual-slop_edit_file` with `old_string` and `new_string`. For each of the 3 sites, replace the `try: ... except ai_client.ProviderError as e: ... except Exception as e: ...` block with `result = ai_client.send_result(...); if not result.ok: err = result.errors[0]; raise HTTPException(status_code=502, detail=err.ui_message())`.
|
||||
- **SAFETY:** HTTP sites return HTTPException; this is the standard pattern. The `_handle_request_event` site (3692) was already changed in Phase 2.
|
||||
- **REFERENCES:** See `docs/guide_app_controller.md` for the API endpoint pattern; see `conductor/code_styleguides/error_handling.md` §3.1 for the Result-handling pattern.
|
||||
- **VERIFY:** `uv run pytest tests/test_ai_loop_regressions_20260614.py::test_fr2_no_provider_error_in_source tests/test_ai_loop_regressions_20260614.py::test_fr2_api_endpoint_handles_send_result_error` — should now PASS.
|
||||
- **VERIFY (AST scan):** `grep -n "ProviderError" src/app_controller.py` — should return no matches.
|
||||
- **COMMIT:** `fix(ai_loop): replace dead ProviderError except clauses with send_result() pattern (FR2, Bug #1)`
|
||||
|
||||
- [ ] **Task 3.2**: Add a comment / docstring to the `_handle_request_event` site referencing the styleguide
|
||||
- **WHERE:** `src/app_controller.py:_handle_request_event` (the function docstring or a comment at the FR1-fix site)
|
||||
- **WHAT:** Add a one-line reference to the data-oriented error handling styleguide, e.g.:
|
||||
```python
|
||||
# FR2 / Bug #1: per conductor/code_styleguides/error_handling.md §3.1 (AND over OR),
|
||||
# we check result.ok instead of catching a ProviderError exception.
|
||||
```
|
||||
- **HOW:** Use `manual-slop_edit_file` to add the comment after the `result = ai_client.send_result(...)` line.
|
||||
- **SAFETY:** Comments are minimal per the project's no-comments rule (see `conductor/product-guidelines.md`); this one is justified because it documents a non-obvious architectural decision.
|
||||
- **VERIFY:** `grep -n "AND over OR" src/app_controller.py` — should return 1 match.
|
||||
- **COMMIT:** Same commit as 3.1; no new commit.
|
||||
|
||||
- [ ] **Task 3.3**: Verify all FR2 tests pass and no other tests regress

|
||||
- **EXPECTED:** All FR2 tests PASS; existing `test_ai_client_result.py` and `test_deprecation_warnings.py` still pass (they were already updated for the Result API).
|
||||
- **COMMIT:** No new commit; this is a verification step.

|
||||
|
||||
## Phase 4: Fix FR3 (Bug #3 — MiniMax Thinking Mono Rendering)
|
||||
|
||||
**Focus:** Wrap `reasoning_content` in `<thinking>...</thinking>` tags in the returned text, mirroring DeepSeek's pattern at `src/ai_client.py:2117-2118`.
|
||||
|
||||
- [ ] **Task 4.1**: Implement the thinking-wrap in `run_with_tool_loop` (preferred) or `_send_minimax`
|
||||
- **WHERE:** `src/ai_client.py:797-836` (`run_with_tool_loop` body) — preferred location because it's a shared helper and the fix benefits any provider that uses `reasoning_extractor` (currently MiniMax and Llama `llama-3.1-405b-reasoning`). Alternative: `src/ai_client.py:2418-2443` (`_send_minimax` body) — only fixes MiniMax.
|
||||
- **WHAT:** In `run_with_tool_loop`, after the `for _round_idx in range(MAX_TOOL_ROUNDS + 2):` loop, BEFORE returning `response_text`, check if `reasoning_content` is non-empty. If yes, wrap it in `<thinking>...</thinking>` tags and prepend to `response_text`. Alternatively, set `response_text = f"<thinking>\n{reasoning_content}\n</thinking>\n\n{response_text}"` at the END of each round.
|
||||
- **HOW:** Use `manual-slop_edit_file` with `old_string` and `new_string`. The change is ~3 lines.
|
||||
- **SAFETY:** DeepSeek ALREADY does this wrap inline (at lines 2117-2118). The fix here is for the OTHER providers that use `reasoning_extractor` (MiniMax, Llama). The fix must be conditional — it should NOT overwrite DeepSeek's existing wrap (which is already there). Check the existing code: DeepSeek's `full_assistant_text = thinking_tags + assistant_text` is set BEFORE the response is added to history. The `run_with_tool_loop` does NOT know about this; it only sees `response.text`. So the fix needs to be in the `run_with_tool_loop`'s `response_text` return — but only for providers that haven't already wrapped.
|
||||
- **CLEANEST APPROACH:** Add a new keyword argument `wrap_reasoning_in_text: bool = False` to `run_with_tool_loop` (default False to preserve existing behavior for providers that wrap inline). In `_send_minimax`, pass `wrap_reasoning_in_text=caps.reasoning` (True when reasoning is enabled). In `run_with_tool_loop`, when `wrap_reasoning_in_text` and `reasoning_content`, prepend `f"<thinking>\n{reasoning_content}\n</thinking>\n\n"` to `response_text` at the end of each round.
|
||||
- **REFERENCES:** See `src/ai_client.py:2117-2118` for DeepSeek's pattern. See `src/thinking_parser.py:9` for the regex that will match the `<thinking>` tag.
|
||||
- **VERIFY:** `uv run pytest tests/test_ai_loop_regressions_20260614.py::test_fr3_minimax_thinking_in_returned_text tests/test_ai_loop_regressions_20260614.py::test_fr3_minimax_thinking_parsed_by_thinking_parser` — should now PASS.
|
||||
- **VERIFY (DeepSeek not regressed):** `uv run pytest tests/test_deepseek_provider.py` — all tests should still pass (DeepSeek's inline wrap happens BEFORE the `run_with_tool_loop` sees the response, so the new `wrap_reasoning_in_text` is unused).
|
||||
- **COMMIT:** `fix(ai_loop): wrap MiniMax reasoning in <thinking> tags for parse_thinking_trace (FR3, Bug #3)`
|
||||
|
||||
- [ ] **Task 4.2**: Verify MiniMax wrap is conditional and other providers unaffected
|
||||
- **Command:** `uv run pytest tests/test_deepseek_provider.py tests/test_llama_provider.py tests/test_grok_provider.py tests/test_qwen_provider.py tests/test_anthropic_provider.py 2>&1 | tee tests/artifacts/ai_loop_regressions_phase4_sweep.log`
|
||||
- **EXPECTED:** All existing tests pass. The 13 regressions from the parent track's `public_api_migration_20260606` may still be present (out of scope; deferred to that track).
|
||||
- **COMMIT:** No new commit; this is a verification step.
|
||||
|
||||
- [ ] **Task 4.3**: Add a `live_gui` regression test for MiniMax thinking-mono rendering
|
||||
- **WHERE:** `tests/test_live_gui_minimax_thinking.py` (new file; small, ~60 lines)
|
||||
- **WHAT:** A `live_gui`-fixture test that mocks the MiniMax client to return reasoning content, triggers a Gen+Send, and polls `get_value("disc_entries")` for an entry with a non-empty `thinking_segments` field.
|
||||
- **HOW:** Use the same pattern as `tests/test_live_gui_ai_loop_error_path.py` (Task 2.2). The poll target is the last `disc_entries` entry's `thinking_segments` list (not `status`).
|
||||
- **SAFETY:** Mock injection via `monkeypatch`.
|
||||
- **VERIFY:** `uv run pytest tests/test_live_gui_minimax_thinking.py` — should PASS.
|
||||
- **COMMIT:** `test(ai_loop): add live_gui test for MiniMax thinking-mono rendering (FR3 verification)`
|
||||
|
||||
---
|
||||
|
||||
## Phase 5: Regression Sweep + Documentation
|
||||
|
||||
**Focus:** Full test suite sweep, doc note for the 2 deferred follow-ups.
|
||||
|
||||
- [ ] **Task 5.1**: Run the full test suite
|
||||
- **Command:** `uv run pytest tests/ 2>&1 | tee tests/artifacts/ai_loop_regressions_phase5_full_suite.log`
|
||||
- **EXPECTED:** All tests pass. The 13 pre-existing regressions from `data_oriented_error_handling_20260606` (`test_llama_provider.py: 3`, `test_llama_ollama_native.py: 4`, `test_grok_provider.py: 3`, `test_minimax_provider.py: 2`, `test_live_gui_integration_v2.py: 1`) may still be present — these are the planned work of `public_api_migration_20260606`, not this track.
|
||||
- **ACTION:** If NEW failures appear (not in the 13 pre-existing), STOP and report to the user. Do not attempt a fix without the user's direction.
|
||||
- **COMMIT:** No new commit; this is a verification step.
|
||||
|
||||
- [ ] **Task 5.2**: Add the 2 follow-up notes to `docs/guide_ai_client.md`
|
||||
- **WHERE:** `docs/guide_ai_client.md` "See Also" section (or the equivalent end-of-doc section)
|
||||
- **WHAT:** Add 3 new bullets:
|
||||
1. **Gemini / Gemini CLI thinking-format compatibility (deferred from `ai_loop_regressions_20260614`)** — the user's complaint included Gemini; the likely cause is a format mismatch between the Gemini SDK output and `parse_thinking_trace`. Empirically investigate by running a Gemini request that produces reasoning and inspecting the raw `resp.text`. See `conductor/tracks/ai_loop_regressions_20260614/spec.md` §13.1.
|
||||
2. **`<think>` (half-width) marker support in thinking_parser (deferred from `ai_loop_regressions_20260614`)** — user screenshot showed `<think>...</think>` format; current `parse_thinking_trace` requires `<thinking>`. The change is small (~3 lines in `src/thinking_parser.py:9`). See `conductor/tracks/ai_loop_regressions_20260614/spec.md` §13.2.
|
||||
3. **Public API Result Migration (planned, separate track `public_api_migration_20260606`)** — the 5 production + 63 test call sites not migrated in this track.
|
||||
- **HOW:** Use `manual-slop_edit_file` with the existing "See Also" section as the anchor.
|
||||
- **COMMIT:** `docs(ai_client): add 2 follow-up notes for ai_loop_regressions_20260614 (Gemini thinking, <think> marker)`
|
||||
|
||||
- [ ] **Task 5.3**: Update `metadata.json` to mark the track complete
|
||||
- **WHERE:** `conductor/tracks/ai_loop_regressions_20260614/metadata.json`
|
||||
- **WHAT:** Change `"status": "active"` to `"status": "completed"`. Update `verification_criteria` to reflect what was actually verified.
|
||||
- **HOW:** Direct file edit.
|
||||
- **COMMIT:** `conductor(track): mark ai_loop_regressions_20260614 as completed`
|
||||
|
||||
- [ ] **Task 5.4**: Conductor — User Manual Verification (Protocol in workflow.md)
|
||||
- **Action:** Announce the track is complete. Provide the user with the acceptance test from `spec.md` §12. Briefly summarize the 3 fixes and the 2 deferred follow-ups.

# Track: AI Loop Regressions (MiniMax, Gemini, Gemini CLI, DeepSeek)
|
||||
|
||||
**Status:** Active (spec approved 2026-06-14)
|
||||
**Initialized:** 2026-06-14
|
||||
**Owner:** Tier 2 Tech Lead
|
||||
**Priority:** High (4 providers broken in production; user-facing symptom)
|
||||
|
||||
---
|
||||
|
||||
## 1. Overview
|
||||
|
||||
This track diagnoses and fixes 4 user-visible regressions in the AI loop that surfaced after the `data_oriented_error_handling_20260606` track shipped (2026-06-12) and the subsequent `ai client pass` commit `5030bd84` (2026-06-13, 503-line `src/ai_client.py` refactor in the Gemini region). The regressions affect **MiniMax (M2.x), Gemini, Gemini CLI, and DeepSeek** — the 4 providers most heavily touched by the refactor.
|
||||
|
||||
The reported symptoms (per user 2026-06-14):
|
||||
1. **Thinking monologues no longer render** in the Discussion Hub.
|
||||
2. **AI turns do not get entries** in the Discussion Hub; the user must manually add them via the `History` button.
|
||||
|
||||
The 2 symptoms are the visible result of **3 distinct bugs** interacting. Bug #2 is the primary culprit for the "no entries" symptom; Bug #3 is the primary culprit for the "no thinking" symptom on MiniMax; Bug #1 is dead code that breaks the error-reporting path. The user-supplied screenshots show entries in the Operations Hub `Comms History` and in the `Comms History` panel — confirming the requests reach the AI client and responses are emitted, but the response doesn't propagate to the discussion panel.
|
||||
|
||||
## 2. Goals (Priority Order)
|
||||
|
||||
| Priority | Goal | Rationale |
|
||||
|---|---|---|
|
||||
| **A (primary value)** | Fix Bug #2: `_handle_request_event` (the live AI send path) routes `send_result()` errors back into the Discussion Hub as error entries, restoring the pre-refactor UX. | The "no entries" symptom is the user-blocking bug. Fixing it makes the AI loop immediately usable again. |
|
||||
| **A (primary value)** | Fix Bug #3: MiniMax thinking content (`reasoning_details[0].text`) is wrapped in `<thinking>...</thinking>` tags in the returned text, so `thinking_parser.parse_thinking_trace` can extract it and the discussion entry shows the thinking segment. | MiniMax is the user's current provider; thinking monologues are a core feature. Without this fix the user cannot see the AI's reasoning. |
|
||||
| **B (architectural)** | Fix Bug #1: replace the 3 dead `except ai_client.ProviderError as e:` clauses in `src/app_controller.py` with the equivalent `send_result()` + `if not result.ok: ...` pattern. | The dead clauses silently swallow the `AttributeError` that arises when Python tries to evaluate `ai_client.ProviderError` to compare against the in-flight exception. The replacement aligns with the data-oriented error handling convention and gives Tier 2 a clean reference for the planned `public_api_migration_20260606` follow-up. |
|
||||
| **C (diagnostic)** | Root-cause verification: each of the 3 fixes is preceded by a failing TDD test that reproduces the bug, and a commit history audit is documented in the spec. | The user explicitly asked for an investigation track. The diagnostic tests are the empirical evidence for each root cause. |
|
||||
| **D (forward-looking)** | Document the deferred Gemini / Gemini CLI thinking-format investigation as a follow-up note in `docs/guide_ai_client.md` "See Also" section. | The user's complaint includes Gemini, but the format-compatibility issue is plausibly a pre-existing limitation, not a new regression. Documented as a follow-up to avoid scope creep. |
|
||||
|
||||
### 2.1 Non-Goals (this track)
|
||||
|
||||
- **Not** migrating the 5 remaining production call sites or 63 test call sites to `send_result()`. The planned `public_api_migration_20260606` follow-up track handles that. This track only migrates the 3 sites that are actively broken (the dead `except` clauses in `app_controller.py:305, 313, 3692`) — the minimum needed to make the live path work.
|
||||
- **Not** expanding the `thinking_parser.py` contract to support new marker formats. The `<thinking>`, `<thought>`, and `Thinking:` markers are the canonical set; the MiniMax fix uses the existing `<thinking>` format (matches DeepSeek's pattern).
|
||||
- **Not** investigating or fixing the Gemini / Gemini CLI thinking-format compatibility (deferred; see §13.1).
|
||||
- **Not** changing the `ProviderError` removal (it was correctly removed in commit `64b787b8`); we only fix the dead except clauses.
|
||||
- **Not** adding a new `thinking_parser` format; we work within the existing 3-marker contract.
|
||||
|
||||
## 3. Current State Audit (as of commit `5030bd84`)
|
||||
|
||||
### 3.1 Already Implemented (DO NOT re-implement)
|
||||
|
||||
- **`src/result_types.py`**: `Result[T]`, `ErrorInfo`, `ErrorKind` dataclasses exist; `Result.data: T` + `Result.errors: list[ErrorInfo]` is the canonical pattern.
|
||||
- **`src/ai_client.py:send_result()`** (lines 2970-3092): the new public entry point, returns `Result[str]`. Routes to `_send_<vendor>_result()` per provider.
|
||||
- **`src/ai_client.py:send()`** (lines 2907-2968): the `@deprecated` shim, calls `send_result()` and returns `result.data`. **Never raises on error** — returns `""` instead.
|
||||
- **`src/ai_client.py:_send_*_result()`** (lines 1291-3082): all 9 vendors (`anthropic`, `gemini`, `gemini_cli`, `deepseek`, `minimax`, `qwen`, `grok`, `llama`, `llama_native`) return `Result[str]` with `ErrorInfo` on failure.
|
||||
- **`src/ai_client.py:run_with_tool_loop()`** (lines 734-836): already extracts reasoning via `reasoning_extractor` and stores it in `history[].reasoning_content`. The reasoning content is in the history but **NOT** in the returned text.
|
||||
- **`src/thinking_parser.py:parse_thinking_trace()`** (lines 8-54): already extracts `<thinking>`, `<thought>`, and `Thinking:` prefix segments.
|
||||
- **`src/app_controller.py:_on_comms_entry()`** (lines 3749-3840): already routes `response` comms entries to `_pending_history_adds` if `text_content.strip()` is truthy and `parse_thinking_trace` finds segments.
|
||||
- **DeepSeek's reasoning wrap pattern** (`src/ai_client.py:2117-2118`): DeepSeek wraps `reasoning_content` in `<thinking>...</thinking>` tags in the final text before returning. This is the reference pattern for the MiniMax fix.
|
||||
|
||||
### 3.2 Gaps to Fill (This Track's Scope)
|
||||
|
||||
| # | File:line | Gap | Symptom |
|
||||
|---|---|---|---|
|
||||
| **G1** | `src/app_controller.py:3677-3697` | `_handle_request_event` calls deprecated `ai_client.send()` and discards the result. On error, `result.data == ""` is queued as a `response` comms entry, but `_on_comms_entry` at line 3801 filters it out via `if text_content.strip():`. No discussion entry is added. | "AI turns are not getting proper entries" |
|
||||
| **G2** | `src/app_controller.py:305, 313, 3692` | Three `except ai_client.ProviderError as e:` clauses reference a class that was removed in commit `64b787b8`. Python evaluates the class on every raised exception; on missing class, the except clause itself raises `AttributeError`. The error path is broken. | Silently dropped error messages (compounding G1) |
|
||||
| **G3** | `src/ai_client.py:797-836, 2418-2443` | `_send_minimax()` uses `reasoning_extractor` to extract reasoning into `history[].reasoning_content`, but the returned `response_text` (and thus `Result.data`) does not include the thinking tags. `parse_thinking_trace` finds no `<thinking>` blocks, so no thinking segments are added to the discussion entry. | "Thinking monologues no longer rendering" (MiniMax) |
|
||||
| **G4** | (deferred) `src/ai_client.py:_send_gemini`, `_send_gemini_cli` | Gemini SDK output may include thinking in a format that `parse_thinking_trace` doesn't match. Empirical verification needed. | "Thinking monologues no longer rendering" (Gemini) |
|
||||
|
||||
## 4. Functional Requirements
|
||||
|
||||
### FR1: Error response becomes a discussion entry (Bug #2 / G1)
|
||||
|
||||
`_handle_request_event` in `src/app_controller.py:3677-3697` must:
|
||||
|
||||
1. Call `ai_client.send_result()` instead of `ai_client.send()`.
|
||||
2. On `result.ok == False`: queue a `response` comms entry with `text=ui_error_message()`, `status="error"`, `role="Vendor API"` so the user sees the error in both the AI response panel AND as a discussion entry.
|
||||
3. On `result.ok == True`: queue a `response` comms entry with `text=result.data`, `status="done"`, `role="AI"` (preserves current behavior).
|
||||
4. Update `_ai_status` to `f"error: {ui_error_message()}"` on failure (preserves the visible status indicator).
|
||||
5. Preserve the existing streaming path (`_on_ai_stream` continues to receive chunks during `stream=True` execution).
|
||||
|
||||
### FR2: Replace dead `except ai_client.ProviderError` clauses (Bug #1 / G2)
|
||||
|
||||
All 3 sites in `src/app_controller.py` (`305, 313, 3692`) must:
|
||||
|
||||
1. Remove the `except ai_client.ProviderError` clause.
|
||||
2. Replace with either:
|
||||
- **For sites that call `ai_client.send()`**: call `ai_client.send_result()` instead; if `not result.ok`, route the error to the API response (HTTPException for the API sites, comms queue for the live site).
|
||||
- **For sites that call other `ai_client` methods that raise**: use a generic `except Exception` and convert to a structured response (HTTPException for API sites, error entry for the live site).
|
||||
3. Reference the data-oriented error handling styleguide (`conductor/code_styleguides/error_handling.md` §3.1) in the resulting code's docstring (so future migrations follow the same pattern).
|
||||
|
||||
### FR3: MiniMax thinking content reaches `parse_thinking_trace` (Bug #3 / G3)
|
||||
|
||||
`_send_minimax` in `src/ai_client.py:2418-2443` (or `run_with_tool_loop` at lines 797-836) must:
|
||||
|
||||
1. When `caps.reasoning` is True AND the previous round extracted non-empty `reasoning_content`, the NEXT round's `response_text` (and `Result.data`) must include the reasoning wrapped in `<thinking>...</thinking>` tags (matching DeepSeek's pattern at `src/ai_client.py:2117-2118`).
|
||||
2. The `run_with_tool_loop` history write at line 808 must continue to store the raw `reasoning_content` (so subsequent API calls can use it for the next turn's reasoning). The thinking tag wrapping is additive: the raw reasoning is in the history, the tagged reasoning is in the visible text.
|
||||
3. The `<think>...</think>` format used by some MiniMax models (visible in the user-supplied screenshot 1) must continue to work — `parse_thinking_trace` already supports it (the regex at `src/thinking_parser.py:22` matches `<thinking>` and `<thought>`; the screenshot shows the `<think>` format which is **not** currently supported — this is a separate bug and is deferred to the follow-up).
|
||||
|
||||
**Important scope clarification**: The user's screenshot shows `<think>This is DWARF debug info...</think>` style — using the half-width `<think>` (no closing match for the regex). The MiniMax fix in this track wraps the reasoning in `<thinking>` (the supported form), not `<think>`. This is a temporary scope reduction: the fix restores thinking-mono rendering for the common case (DeepSeek-style `<thinking>` tags), and the half-width `<think>` format is a known gap that's documented as a follow-up.
|
||||
|
||||
### FR4: No new files in `src/`
|
||||
|
||||
Per the project's hard rule (see `AGENTS.md` "File Size and Naming Convention"), no new `src/<thing>.py` files. All fixes go in:
|
||||
- `src/app_controller.py` (FR1, FR2)
|
||||
- `src/ai_client.py` (FR3)
|
||||
|
||||
### FR5: Tests cover all 3 fixes
|
||||
|
||||
- `tests/test_ai_loop_regressions_20260614.py` (new file): TDD tests for FR1, FR2, FR3.
|
||||
- **FR1 tests** (3+ tests): (a) successful response becomes a discussion entry; (b) error response becomes a discussion entry with `status="error"`; (c) `_ai_status` is updated correctly on both paths.
|
||||
- **FR2 tests** (2+ tests): (a) the dead `except ProviderError` clause is removed (assert no longer present via AST scan); (b) the replaced code path correctly raises HTTPException for the API sites.
|
||||
- **FR3 tests** (2+ tests): (a) `_send_minimax` returns `Result.data` that contains `<thinking>` tags when reasoning is extracted; (b) the discussion entry's `thinking_segments` field is populated when `parse_thinking_trace` is run on the result.
|
||||
|
||||
## 5. Non-Functional Requirements
|
||||
|
||||
- **NFR1 (Atomic per-task commits)**: each plan task is one commit; no batching.
|
||||
- **NFR2 (1-space indentation)**: enforced by the project's AI-Optimized Python style.
|
||||
- **NFR3 (No diagnostic noise in production)**: no `sys.stderr.write("[XYZ_DIAG] ...")` lines in the committed code. If instrumentation is needed for the TDD test, it goes to `tests/artifacts/<test_name>.diag.log` (not in the test file itself).
|
||||
- **NFR4 (Backward compatibility)**: the deprecated `ai_client.send()` shim remains working (the `public_api_migration_20260606` track is responsible for removal; this track only fixes the 3 broken except clauses).
|
||||
- **NFR5 (No regression in other providers)**: the 5 unaffected providers (Anthropic, Qwen, Grok, Llama, Llama native) must continue to pass their existing tests.
|
||||
- **NFR6 (Thread safety)**: all fixes preserve the existing `_send_lock` and per-provider history locks; the fix for FR1 must not introduce a new race between the streaming `_on_ai_stream` callback and the final `result.data` write.
|
||||
|
||||
## 6. Architecture Reference
|
||||
|
||||
For implementation details, consult:
|
||||
|
||||
- **`docs/guide_ai_client.md`**: the canonical guide for `src/ai_client.py`; the new `send_result()` API is documented in the "Data-Oriented Error Handling (Fleury Pattern) > Public API" section. FR1 and FR3 should follow the patterns shown there.
|
||||
- **`docs/guide_app_controller.md`**: the canonical guide for `src/app_controller.py`; the `_handle_request_event` and `_on_comms_entry` flows are described in §"AI Loop Lifecycle". FR1 and FR2 changes are in this subsystem.
|
||||
- **`docs/guide_thinking.md`** (if it exists; otherwise `docs/guide_discussions.md`): the canonical guide for thinking-mono rendering; the `parse_thinking_trace` markers are documented in §"Thinking Markers".
|
||||
- **`conductor/code_styleguides/error_handling.md`**: the canonical reference for the Result/ErrorInfo pattern; the new FR2 code paths should follow §3.1 "AND over OR (Result struct with side-channel errors)".
|
||||
- **`docs/reports/data_oriented_error_handling_phase3_20260612.md`** (if it exists; otherwise the metadata.json `deprecation_strategy` section of the parent track): documents the `send_result()` deprecation strategy and the planned `public_api_migration_20260606` follow-up.
|
||||
|
||||
## 7. Out of Scope
|
||||
|
||||
- **Gemini / Gemini CLI thinking-format compatibility investigation** (Bug #4 / G4). The user's complaint includes Gemini, but the format may be a pre-existing limitation. Documented as a follow-up in §13.1.
|
||||
- **Migrating the remaining 5 production call sites + 63 test call sites to `send_result()`**. The planned `public_api_migration_20260606` track handles this.
|
||||
- **Expanding `thinking_parser.py` to support new marker formats** (e.g., `<think>` without closing `</think>`).
|
||||
- **Restructuring `_handle_request_event` to be testable in isolation** (a follow-up; this track's tests use mocks for the AI client, not the controller).
|
||||
- **Any changes to the `multi_agent_conductor.py` MMA worker interface** (it still uses `send()`; will migrate in the public_api track).
|
||||
- **Restoring the `<think>` (half-width) marker support**. The user's screenshot shows this format; the current `parse_thinking_trace` regex requires `<thinking>` (full-width). This is a separate gap documented in §13.2.
|
||||
|
||||
## 8. Phases (Summary)
|
||||
|
||||
| Phase | Name | Tasks | Verification |
|
||||
|---|---|---|---|
|
||||
| **Phase 1** | **Root-cause verification** (TDD red) | 3 tasks: write 3+ failing tests for FR1, FR2, FR3; commit each as a separate test | `pytest tests/test_ai_loop_regressions_20260614.py` shows red |
|
||||
| **Phase 2** | **Fix FR1 (Bug #2): error response becomes a discussion entry** | 3 tasks: implement the fix in `_handle_request_event`; run the FR1 tests; commit | `pytest tests/test_ai_loop_regressions_20260614.py::test_*fr1*` shows green |
|
||||
| **Phase 3** | **Fix FR2 (Bug #1): replace dead `except ProviderError` clauses** | 3 tasks: replace 3 sites; run the FR2 tests; commit | `pytest tests/test_ai_loop_regressions_20260614.py::test_*fr2*` shows green; AST scan shows no `ProviderError` references |
|
||||
| **Phase 4** | **Fix FR3 (Bug #3): MiniMax thinking mono rendering** | 3 tasks: wrap reasoning in `<thinking>` tags in `_send_minimax` (or in `run_with_tool_loop`); run the FR3 tests; commit | `pytest tests/test_ai_loop_regressions_20260614.py::test_*fr3*` shows green |
|
||||
| **Phase 5** | **Regression sweep + docs** | 3 tasks: run full `pytest tests/`; add follow-up note to `docs/guide_ai_client.md` "See Also" section; commit | Full suite green; doc note present |
|
||||
|
||||
## 9. Risk Analysis
|
||||
|
||||
| Risk | Likelihood | Impact | Mitigation |
|
||||
|---|---|---|---|
|
||||
| **R1**: The Phase 4 fix (MiniMax thinking wrap) breaks the existing DeepSeek tests because both use `run_with_tool_loop`. | Medium | High | Apply the wrap only when `reasoning_extractor` is set AND returns non-empty; preserve the DeepSeek-specific path (which already wraps). The fix is conditional on `caps.reasoning`, not universal. |
|
||||
| **R2**: The FR1 fix changes the streaming behavior — the streaming chunks go through `_on_ai_stream` (via `stream_callback`), and the final `result.data` is set after streaming completes. The fix must not break the existing streaming contract. | Medium | High | The FR1 fix only changes the FINAL response comms entry (after `send_result()` returns). The streaming path is unchanged. Phase 2's test must include a streaming test to lock this. |
|
||||
| **R3**: The 3 sites in `app_controller.py` that have `except ProviderError` may have other callers depending on the exception behavior. | Low | Medium | All 3 sites are in `_handle_request_event` (1 site) and 2 API hook endpoints (`/api/v1/generate`, `/api/v1/generate_sync`). The fix routes errors the same way the original code intended, just via `Result.ok` instead of `ProviderError`. |
|
||||
| **R4**: The `parse_thinking_trace` regex is greedy; wrapping thinking in `<thinking>` tags and then parsing it may produce nested segments. | Low | Low | The regex at `src/thinking_parser.py:9` is `re.DOTALL \| re.IGNORECASE` and uses `.*?` (non-greedy). Nested `<thinking>` blocks would not match because the outer block consumes the inner; this is the same behavior DeepSeek has, and the existing tests pass for DeepSeek. |
|
||||
| **R5**: The user is wrong about Gemini / Gemini CLI — those may not actually be broken. | Medium | Low | The deferred Phase-5-style follow-up will investigate empirically. The user's primary report was MiniMax; the other 3 are mentioned as "all regressed" but the fix for Bug #1 (dead except clauses) and Bug #2 (empty data) restores them all to working order. The thinking-mono issue is MiniMax-specific. |
|
||||
|
||||
## 10. Coordination with Pending Tracks
|
||||
|
||||
This track is **independent** (no `blocked_by` and no `blocks` in `metadata.json`). It does not depend on or block any active track.
|
||||
|
||||
However, it interacts with:
|
||||
- **`public_api_migration_20260606`** (planned, not yet specced): this track's FR1 fix to `_handle_request_event` is a partial migration. The full migration (5 production + 63 test sites) is out of scope here; the follow-up track picks up where this leaves off. The two tracks share the same destination but this track fixes the user-blocking regressions first.
|
||||
- **`data_oriented_error_handling_20260606`** (shipped 2026-06-12): this track is the user-facing bug-fix for the issues introduced by the parent track. It does not modify any of the 3 files the parent track touched (`mcp_client.py`, `ai_client.py`, `rag_engine.py`); it only modifies `app_controller.py` (the 1 file the parent track did NOT touch). The MiniMax fix touches `ai_client.py` for FR3 (1 file the parent touched).
|
||||
- **`qwen_llama_grok_followup_20260611`** (archived 2026-06-11): no direct interaction, but the MiniMax fix in FR3 follows the same reasoning-extraction pattern that track introduced for the OpenAI-compatible providers.
|
||||
|
||||
## 11. Verification Criteria (definition of "done")
|
||||
|
||||
The track is complete when ALL of the following are true:
|
||||
|
||||
- [ ] All 3 phase 1-4 tests pass (`pytest tests/test_ai_loop_regressions_20260614.py` shows green).
|
||||
- [ ] Full test suite passes (`uv run pytest tests/` shows green; no new failures).
|
||||
- [ ] `grep -rn "ProviderError" src/` returns no matches.
|
||||
- [ ] `grep -rn "ai_client\.ProviderError" src/` returns no matches.
|
||||
- [ ] Live GUI test: a MiniMax `M2.7` request with reasoning returns a discussion entry that includes a `thinking_segments` field (use the `live_gui` fixture + `ApiHookClient.get_value("disc_entries")`).
|
||||
- [ ] Live GUI test: a MiniMax request that fails (e.g., invalid API key) returns a discussion entry with `status="error"` and the error message in the `content` field.
|
||||
- [ ] Live GUI test: a Gemini request that succeeds returns a discussion entry (verifies the FR1 fix doesn't break Gemini).
|
||||
- [ ] `docs/guide_ai_client.md` "See Also" section includes the 2 follow-up notes (§13.1 Gemini thinking investigation, §13.2 `<think>` half-width marker support).
|
||||
- [ ] `metadata.json` `verification_criteria` field is updated to reflect completion.
|
||||
|
||||
## 12. Acceptance Test (the user can verify this themselves)
|
||||
|
||||
After this track ships, the user should be able to:
|
||||
|
||||
1. Open Manual Slop with MiniMax as the active provider.
|
||||
2. Send a message that requires the AI to reason (e.g., "explain the structure of this function").
|
||||
3. Verify: the AI's response appears in the Discussion Hub **without** manually pressing the `History` button.
|
||||
4. Verify: the response has a `Monologue` collapsible section showing the AI's thinking.
|
||||
5. Trigger a failure (e.g., switch to an invalid MiniMax API key, then send a message).
|
||||
6. Verify: an error entry appears in the Discussion Hub with the error message.
|
||||
|
||||
Before this track ships, steps 3 and 4 fail (for MiniMax); step 6 fails (for all 4 affected providers).
|
||||
|
||||
## 13. See Also — Follow-up Notes
|
||||
|
||||
### 13.1 Gemini / Gemini CLI thinking-format compatibility (deferred)
|
||||
|
||||
The user's complaint includes Gemini and Gemini CLI. The likely cause is a format mismatch between what the Gemini SDK outputs and what `parse_thinking_trace` recognizes:
|
||||
|
||||
- `parse_thinking_trace` (`src/thinking_parser.py:9`) matches `<thinking>`, `<thought>`, and `Thinking:` prefix.
|
||||
- The Gemini SDK's `resp.text` may include thinking as plain prose or as `*thinking aloud*` markdown, depending on the SDK version and the model's prompt formatting.
|
||||
|
||||
This track fixes Bugs #1, #2, #3. The Gemini / Gemini CLI thinking-format issue is plausibly a pre-existing limitation (the existing tests for `parse_thinking_trace` show it doesn't match all Gemini output formats) rather than a new regression from the recent refactor.
|
||||
|
||||
**Follow-up track** (to be specced): investigate empirically by running a Gemini request that produces reasoning and inspecting the raw `resp.text`; add a normalization pass in `_send_gemini*` if needed.
|
||||
|
||||
### 13.2 `<think>` (half-width) marker support (deferred)
|
||||
|
||||
The user's screenshot 1 shows a discussion entry containing `<think>This is DWARF debug info, not the actual disassembly...</think>` — the half-width `<think>` form (no closing `</think>` in the regex). The current `parse_thinking_trace` regex (`src/thinking_parser.py:9`) requires the full `<thinking>` form. Some models (notably certain DeepSeek-R1 outputs and possibly the MiniMax M2.7 output) use the half-width `<think>` form.
|
||||
|
||||
**Follow-up track** (to be specced): extend `parse_thinking_trace` to support the half-width `<think>...</think>` form (the closing tag is the same). The change is small (~3 lines in `src/thinking_parser.py:9`); the test file is `tests/test_thinking_trace.py` (5+ existing tests for the full-width form).
|
||||
|
||||
### 13.3 Public API Result Migration (planned, separate)
|
||||
|
||||
The `public_api_migration_20260606` follow-up (planned, not yet specced) will migrate the 5 remaining production call sites and 63 test call sites to `send_result()`. This track fixes the 3 sites in `app_controller.py` that are actively broken; the public_api track picks up from there.
