It also adds bounded LLM retries and transactional commit recovery for API and tool-loop failures. ChangesDraft persistence and retry flow
Estimated code review effort: 4 (Complex) | ~45 minutes Merge Risk: 🔵 Low · up to The PR adds staged-message persistence, interrupt handling, and retry behavior. A post-commit interruption may display misleading recovery guidance, an invalid editor configuration may eventually terminate the interactive session, and permanent API errors may incur unnecessary retry delays. The PR is mergeable with explicit owner awareness and follow-up on these bounded interaction and runtime issues. Sequence Diagram(s)sequenceDiagram

572-583: 🗄️ Data Integrity & Integration | 🔵 Trivial | ⚡ Quick winVerify the assistant message before you pop it.
Line 578 pops the preceding assistant message after it removes the
tool_resultmessage. It only checks the role. Todaystep()always appends atool_resultmessage directly after an assistanttool_usemessage, so the pop is correct. If that ordering ever changes, this code silently deletes a valid assistant reply.MyAgent._msg_ends_with_tool_usealready exists insrc/core/agent.pyand handles both dict blocks and SDK objects. Reuse it.♻️ Proposed precise pop
if isinstance(tail, list) and tail and tail[0].get("type") == "tool_result": hist.pop() - if hist and hist[-1]["role"] == "assistant": + # Only the paired tool_use turn may be dropped; a plain-text + # assistant reply must survive. + if hist and MyAgent._msg_ends_with_tool_use(hist[-1]): hist.pop() # End-if # End-ifThis needs
MyAgentin scope. If importing it here creates a cycle, call the helper through the agent instance instead.🤖 Prompt for AI Agents

499-509: 🩺 Stability & Availability | 🔵 Trivial | ⚡ Quick winConsider a cap on the tool-loop iterations.
_run_agent_loopcontinues whilestep()reportscont=True. A model that repeatedly requests tools keeps the loop running with no bound. Each iteration is a paid API call, and the bounded retries added insrc/core/agent.pymake each failing iteration take up to 14 seconds of backoff. This mirrors the previous loop behavior, so it is not a regression, but the extraction is a good place to add the bound.♻️ Proposed iteration cap
- def _run_agent_loop(self): + def _run_agent_loop(self, max_turns=100): while True: + if max_turns <= 0: + return False, "Tool loop exceeded the maximum number of turns." + # End-if + max_turns -= 1 cont, err = self.agent.step() if err is not None: return False, err # End-if if not cont: return True, None # End-if # End-whileNote: the caller at line 440 discards the first return value, so the cap surfaces through the
errchannel and reuses the existing message path.🤖 Prompt for AI Agents

50-55: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick winConsider excluding non-retryable errors and deriving the retry count from the backoff tuple.
Two points on this policy:
- A uniform policy retries permanent failures. A 400 (malformed payload) or a 401 (bad API key) never recovers. The user then waits 14 seconds of backoff before seeing the error. If
SafeLLMClientexposes the status code or a classifiable error, skip the retries for permanent failures._LLM_RETRY_COUNTand_LLM_RETRY_BACKOFFmust stay in sync. Line 758 indexes_LLM_RETRY_BACKOFF[attempt - 1]for attempts1.._LLM_RETRY_COUNT. If a later change raises the count to 4 and leaves the tuple at three entries, that line raisesIndexError. Derive the count from the tuple instead.♻️ Proposed decoupling of the count and the backoff schedule
-_LLM_RETRY_COUNT = 3 -_LLM_RETRY_BACKOFF = (2, 4, 8) +_LLM_RETRY_BACKOFF = (2, 4, 8) +# Retry count is derived so the two constants can never drift apart. +_LLM_RETRY_COUNT = len(_LLM_RETRY_BACKOFF)🤖 Prompt for AI Agents

In `@src/utils/cli/interactive_cli.py`:
- Around line 483-488: Update the interrupt handling around _run_agent_loop so
it distinguishes interrupts during Phase 1 from those during Phase 2: after the
draft has been cleared and the user message committed, report that sending was
aborted without claiming the draft was preserved; retain the existing rollback
and draft-preserved message only for interrupts occurring before acceptance.
- Around line 300-309: Handle FileNotFoundError locally around subprocess.call
in the editor flow, report that the configured editor could not be launched, and
preserve the existing staged draft without allowing the exception to propagate
to run(). Keep the normal load_staged and buffer-update behavior unchanged when
the editor starts successfully.
