ApprovabilityVerdict: Not approved Macroscope's review found this PR not approvable — This PR adds a new reasoning-cycle capability while changing composer prompt/model state, shared keyboard matching, and Claude Ultrathink behavior across existing paths. It also changes the shipped default keybindings, so the resulting product-wide shortcut behavior merits human review. No code changes detected at You can add or adjust custom eligibility rules.

One finding: the reasoning-cycle shortcuts are routed through the stash-only guards in ChatComposer, so alt+, / alt+. can open the stash picker instead of changing reasoning.

Reviewed the web-side changes for UI/interaction consistency. One new finding on the keyboard reasoning-cycle path in ChatComposer.tsx (caret position lost when the Ultrathink prefix is added/removed).
The previously reported issue — reasoning shortcuts falling through the stash-specific guards (pendingUserInputs opens the stash picker, approval/project-selection/pending-progress silently swallows the command) — still applies at ChatComposer.tsx lines 2567-2573 and is not re-posted here.

One concrete issue: the new reasoning shortcut path mutates the draft prompt and the shared composer cursor even when the editor is not bound to the draft prompt (pending provider answer / approval state). Details inline.

Reviewed the composer/traits reasoning-cycle changes for interaction consistency with the existing traits-menu path. Two findings in apps/web/src/components/chat/ChatComposer.tsx; the TraitsPicker refactor itself looks behavior-preserving (the blocked case is still communicated in-menu by the inline notice plus disabled radio items).

One consistency finding in apps/web/src/components/chat/TraitsPicker.tsx: the traits menu's blocked-state UI no longer agrees with the shared reasoning transition it now delegates to, so some clicks are silently discarded.

One finding on the new reasoning-cycle shortcuts. The prior rounds' findings (stash-guard fall-through, caret preservation, draft-vs-pending-answer targeting, event.repeat, and the traits-menu blocked-state mismatch) all look resolved at this head.

Recompute the composer cursor and trigger from the restored draft when a pending question closes, so a menu opened from the custom answer does not stay open against the draft. Persist prompt-backed reasoning transitions and report blocked ones even while an approval or pending question hides the editor.
Extract the reasoning cycle into a callback so the window shortcut listener no longer re-binds on every caret move, drop an unused effect dependency, collapse the model option branching in the shared transition, fold the two programmer-error statuses into unsupported, reword the unsupported toast, and document the shortcuts.

A reasoning shortcut during an approval updates the draft while the editor is hidden. Flag the draft for the same cursor and trigger rebuild that pending answers already use, and drop the render-time cursor ref.

Main added its own optional getModifierState declaration and an AltGraph guard that rejects punctuation keys. The branch already keeps only the layout key during AltGraph input, which covers the same case, so drop the duplicate declaration and the redundant guard.

Note This comment is posted by Julius' dot Closing for missing prior product approval. This ships new default reasoning shortcuts and changes how keyboard and existing traits selections update Claude prompts and saved options. Those default and workflow choices go beyond an optional binding for an established action. The PR and discussion contain no maintainer approval of that direction or scope. Discuss the proposed defaults and prompt behavior with maintainers and link their approval before requesting reconsideration. |

Users can choose reasoning levels from the traits picker, but could not configure shortcuts to move through the selected model reasoning levels.
This adds
reasoning.decreaseandreasoning.increasewithCmd+Alt+,andCmd+Alt+.defaults. A shared pure transition owns advertised-order wraparound, provider option preservation, and Claude Ultrathink prompt entry and exit, so mouse and keyboard behavior stay aligned. The web keybinding layer handles macOS physical punctuation, Settings records the portable chords, and the composer applies changes to the next draft while consuming guarded or unsupported shortcuts safely.Surfaces: web implements the behavior; desktop inherits web; mobile remains unchanged; no provider RPC or wire capability changes.

Ultrathink:\nprefix, but nothing removes that prefix if the user then types a slash command. The resulting prompt isUltrathink:\n/compactrather than beginning with/, so it is sent as prose and the command does not run (the existingapplyClaudePromptEffortPrefixcomment explicitly identifies this failure). The slash-command guard only handles a command that was already present when the transition ran. [ Already posted ]Note
Medium Risk
Touches composer draft state, model option persistence, and global keybinding resolution (including AltGraph and macOS punctuation), where regressions could mis-cycle reasoning or steal keystrokes.
Overview
Adds
reasoning.decreaseandreasoning.increasedefault shortcuts (mod+alt+,/mod+alt+., disabled while the terminal is focused) and wires them in the chat composer to cycle the current model’s reasoning level, update persisted provider options, and adjust the Claude Ultrathink prompt prefix when applicable.Introduces shared
resolveReasoningTransition(plusresolveTraitsSelectChangein the traits picker) so keyboard and mouse reasoning changes share the same wraparound, option preservation, ultrathink add/remove/body-conflict rules, and explicit blocked/unsupported outcomes; the composer shows toasts for blocked or unsupported cases and keeps the caret stable viamapComposerCursorAcrossLeadingPromptChange.Keybinding matching and settings recording now treat macOS Option+comma/period as portable
,/.(physicalComma/Periodaliases), and non-macOS AltGraph events match layout keys only so typed punctuation is not mistaken for shortcuts. Also defers overwritingpromptRefwhile a pending progress question is active.Reviewed by Cursor Bugbot for commit 29afea0. Bugbot is set up for automated code reviews on this repo. Configure here.
