description	Review changed code for bugs and quality, then simplify. Takes a PR number, file paths, or no args for local changes.

Review workflow: get the diff, spawn a code-reviewer agent, then run /simplify on the changed files. Don't narrate each step — just run the tools silently and report findings at the end.

Step 1: Get the diff

Parse $ARGUMENTS to determine the diff source:

• Number (e.g., 123): GitHub PR. Use gh pr diff $NUM for the diff.
• jj revset (prefixed with rev, e.g., rev @-, rev trunk()..@): Use jj diff --git -r <revset> for single revisions or jj diff --git --from <from> --to <to> for ranges.
• File paths: Local changes scoped to those files. Use jj diff --from 'trunk()' --git -- <paths>.
• Natural language or empty: Infer what to review from the conversation context. Identify which files were recently changed in this session and use jj diff --git scoped to those files. If no conversation context exists, fall back to all local changes via jj diff --from 'trunk()' --git.

Step 2: Detect authorship (PR reviews only)

For PR reviews, run gh pr view $NUM --json author --jq .author.login and compare against the current user (gh api user --jq .login). Pass this context to the agent:

• Same user → "This is a self-review of your own code."
• Different user → "This is a review of someone else's code."

Step 3: Review

Spawn a my-code-reviewer agent with the diff and authorship context. Let it produce its full report.

Step 4: Simplify

Skip this step for non-self-authored GitHub PRs (not our code to simplify).

For local changes and self-authored PRs, determine which files were changed from the diff or args, then run /simplify on those files.
