simplify-code
Review a diff for clarity and safe simplifications, then optionally apply low-risk fixes.
Simplify Code
Review changed code for reuse, quality, efficiency, and clarity issues. Use Codex sub-agents to review in parallel, then optionally apply only high-confidence, behavior-preserving fixes.
When to Use
- When the user asks to simplify, clean up, refactor, or review changed code.
- When you want high-confidence, behavior-preserving improvements on a scoped diff.
Modes
Choose the mode from the user's request:
review-only: user asks to review, audit, or check the changessafe-fixes: user asks to simplify, clean up, or refactor the changesfix-and-validate: same assafe-fixes, but also run the smallest relevant validation after edits
If the user does not specify, default to:
review-onlyfor "review", "audit", or "check"safe-fixesfor "simplify", "clean up", or "refactor"
Step 1: Determine the Scope and Diff Command
Prefer this scope order:
- Files or paths explicitly named by the user
- Current git changes
- Files edited earlier in the current Codex turn
- Most recently modified tracked files, only if the user asked for a review but there is no diff
If there is no clear scope, stop and say so briefly.
When using git changes, determine the smallest correct diff command based on the repo state:
- unstaged work:
git diff - staged work:
git diff --cached - branch or commit comparison explicitly requested by the user: us

accesslint-diff
Diff a live page's accessibility violations against a baseline — by default compares uncommitted changes (stash-based), or pass --branch [<name>] to diff against a branch. Reports only new violations introduced, violations fixed, and pre-existing count. Use `scan` for a full audit with no diffing.
accesslint-scan
Audit a live page for accessibility issues, locate each WCAG violation precisely, and return a selector-grounded fix worklist without editing.
accint-commitments
Triage acc's open promises and close them with honest real-world verdicts via acc_act(runtime="outcome").
accint-frames
Drain acc's deliberation queue — open/waiting brain_frames checkpointed by headless runs — via acc_act(runtime="continue").
accint-solve
Route a goal through acc's scored-memory loop via acc_act(runtime="solve"); deliberate any returned brain_frame and submit via continue.
