plan-harder skill is blocked

On codex cli 0.101.0

The agent cannot complete all phases.

In code mode it stops at phase 3 as request_user_input tool available in not possible in code mode:

TL;DR: I completed a partial plan-harder flow focused on research + planning, then stopped because your request was planning/
investigation only and did not ask for implementation or subagent review.

Phases I actually ran:

1. Phase 0 (Research)
   I inspected the lifecycle and reliability code paths (BackgroundRefreshManager, PrayerTimesViewModel,
   NotificationSchedulingService, PrayerNotifications, Info.plist, tests/docs) to map rare-launch risks.
2. Phase 2 (Create Plan)
   I authored docs/plan/rare_launch_background_implications.md with phased, testable tasks, acceptance criteria, risks, and
   constraints.
3. Phase 3 (Save)
   I saved the plan file on branch plan/background-reliability-implications.

What I did not run:

• Phase 1 (Clarify via request_user_input): unavailable in Default collaboration mode.
• Phase 4 (post-save gotchas with request_user_input): same reason.
• Phase 5 (subagent review): I did not invoke it; I stopped after delivering the plan because your request was to “plan harder /
  investigate implications,” not to implement or run review loops.

If you want, I can run a strict Phase 5-style review now by invoking a reviewer subagent on that plan.

In plan mode, it cannot write files and stops before phase 3:

TL;DR: I completed planning-oriented phases only and stopped because of Plan Mode constraints plus your request sequence.

Phases I went through:

1. Phase 0 (research/discovery)
   I scanned the repo for lifecycle, background refresh, notification scheduling, localization UX, and existing rare-launch docs.
2. Phase 1/2 (intent + implementation chat in Plan Mode)
   I iterated on assumptions using request_user_input until the UX became decision-complete:

• 3-day core notification window
• W1/W2/W3 warnings
• exactly one actively scheduled event gap between warnings
• one-shot W3

3. Plan finalization
   I produced the finalized <proposed_plan> block.

Why I stopped at this point:

• In this session, we are explicitly in Plan Mode, which forbids mutating repo-tracked files.
• So when you asked to copy the plan into docs/plan, I had to stop and report that file writes are blocked until Plan Mode is exited.
• I also did not run plan-harder Phase 5 reviewer-subagent loop, because we stayed in conversational Plan Mode flow and focused on finalizing the plan content directly.

Yeah @nenovil what you have to do is press ESC at the end, and shift+tab out of it, and then ask it to write the plan to a file. I am asking them to update plan mode accordingly but unfortunately this is the way to get around it. it's easy, but a little annoying. I hope they change it soon!
