- description:
- Identify and apply refactoring opportunities — supports full analysis, cleanup, simplify, structure, naming, and DRY focus modes.
- allowed-tools:
- Read, Glob, Grep, Edit, Write, Bash(git diff:*), Bash(git branch:*)
- argument-hint:
- [file/dir|staged] [full|cleanup|simplify|structure|naming|dry]
Context
- Branch: !
git branch --show-current - Changed files: !
git diff --name-only HEAD - Diff stats: !
git diff --stat HEAD
Task
Analyze code for refactoring opportunities, present findings, apply with user approval.
Parse Arguments
$ARGUMENTS may contain a target and/or focus mode.
- Target: file path, directory,
staged, or empty (defaults to changed files) - Mode:
full,cleanup,simplify,structure,naming,dry
If empty, ask which mode:
| Mode | What |
|------|------|
| full | All categories |
| cleanup | Dead code, unused imports, debug artifacts, commented-out code |
| simplify | Unnecessary indirection, premature abstractions, over-nested logic |
| structure | Extract/split large functions (>50 lines) and files (>300 lines), move misplaced code |
| naming | Inconsistent names, misleading names, missing is_/has_ prefixes on booleans |
| dry | Within-file and cross-file duplication, copy-pasted code with minor variations |
Step 1: Read
Read all target files + surrounding module context. Identify existing patterns and conventions.
Step 2: Analyze
Identify opportunities based on mode. Present findings only — no changes yet.
Step 3: Present
### Refactoring Opportunities
**Target:** [what was analyzed, which mode]
### Findings
1. src/auth.rs:L42: bug: `validate_and_process_token` is 80 lines. Extract `validate_token`, `process_token`, `log_auth_event`.
2. src/auth.rs:L15: nit: `fn helper` → `extract_bearer_token`.
3. src/utils.rs:L30: nit: unused import `std::collections::BTreeMap`. Remove.
### Verdict: [count] bug / [count] risk / [count] nit
Severity: bug (structural issues, large functions, significant duplication), risk (naming, minor duplication, verbose patterns), nit (unused imports, dead code, cosmetic).
Ask user which findings to apply.
Step 4: Apply
For each approved refactor: make edit, verify surrounding code (imports, callers).
Step 5: Verify
Spawn matching *-reviewer agent(s) on changed files. Fix trivial issues, flag the rest.
Rules
- Never refactor without presenting findings first
- Never change code user didn't approve
- Match existing project patterns
- Flag public API changes explicitly before applying
- Atomic refactors — one logical change at a time
