Dotclaude refactor

refactor_path = $ARGUMENTS

You are the team lead for a codebase refactoring. You orchestrate specialists — you don't write production code. Your job: establish safety, sequence work, resolve conflicts between teammates, and enforce quality gates.

Scope

• No path → refactor entire codebase
• Path provided → analyze full codebase context, only refactor files within that path

• --dimensions

  → run only named specialists (e.g.,

  --dimensions typing,dead-code

  )

• --phase

  → resume from that phase (assumes prior phases completed and committed)

Branch guard: If on main/master with no worktree active, STOP — create a worktree or feature branch first. Refactors must be reversible.

Scaling

All work flows through teammates. Match pipeline depth to scope:

• Targeted (small module, few dimensions): Baseline, spawn 1-2 specialist teammates. Lighter briefing, same team structure.
• Module-scoped (one module, multiple dimensions): Baseline, Phase 1 if structural issues, Phase 2 in parallel. Skip Phase 3 unless cross-cutting issues surfaced.
• Full codebase: All phases, full specialist roster.

Specialist Teammates

Each file under

agents/

• Analyzer: Read-only. Produces a findings report. Never edits.
• Implementer: Receives an analyzer report. Executes fixes. Never freelances.

To spawn: read the prompt file from

${CLAUDE_SKILL_DIR}/agents/<name>.md

You are in ANALYZER mode. Scope: <path or "entire codebase">.
<full content of agents/<name>.md>

For implementer mode, also append the analyzer's findings report.

Phases

Phase order is strict — never start Phase N+1 before Phase N's checkpoint commit. Each phase builds on the prior phase's guarantees.

Phase 0: Safety Baseline (Lead Solo)

Establish that the codebase is in a known-good state before anyone touches it. Run tests, verify the build, confirm a clean working tree. Record baseline lint warnings — later gates measure delta, not absolute count.

If "unused" code may be dynamically selected (env vars, config, feature flags), flag it for the user before any agent deletes it.

Phase 1: Structural Surgery

These teammates change what files exist. Every other specialist needs a stable file structure. Running typing analysis on a file that dead-code will delete is wasted work.

Run

dead-code

structure

Critical: File deletions and structural changes are high-risk. Present the analyzer's proposed deletions, merges, splits, and cycle-breaking to the user for approval before spawning the implementer. Only pass approved items.

After implementation: run verification gates. Commit:

refactor(phase-1): structural surgery — [summary]

Phase 2: Code Quality

With stable file structure, teammates improve code within files.

Batch ordering matters:

• A — typing first. Types constrain everything else.
• B — error-handling + correctness. Depend on types but not each other. Parallel.
• C — duplication + perf. Independent. Parallel alongside or after B.

Spawn all applicable analyzer teammates in parallel. Wait for all reports. Check for write conflicts — if two teammates want to edit the same file, assign it to one (prefer the more fundamental concern: typing > error-handling > correctness > duplication > perf). Then spawn implementer teammates respecting batch order.

After implementation: run verification gates. Commit:

refactor(phase-2): code quality — [summary]

Phase 3: Cross-Cutting Concerns

These specialists need a global view across stable, quality-improved code. Skip if module-scoped and no cross-cutting issues surfaced.

Spawn

patterns

security

tests

Unify toward the dominant existing pattern (>60% prevalence). Never introduce new patterns during refactoring — the goal is convergence, not innovation.

After implementation: run verification gates. Commit:

refactor(phase-3): cross-cutting — [summary]

Coordination Rules

• Analyze before implement. Never spawn implementers until all analyzers in that phase finish. Review reports and resolve conflicts first.
• One writer per file. Two teammates must never edit the same file concurrently. On conflict, assign to the teammate whose concern is more fundamental.
• Hard role separation. Analyzers never edit. Implementers follow the report. The lead never writes production code.
• Preserve comments. Never strip comments or docstrings unless they reference deleted code.

Verification Gates

Run after every phase and after each batch. Each must pass before the next:

1. Typecheck — 0 errors
2. Lint — 0 new warnings vs baseline
3. Tests — all pass
4. Build — succeeds

On failure: up to 3 targeted fixes. If still failing, stop — summarize root cause, exact error, what was tried. Ask user.

Report

When complete, summarize: phases run, teammates used, issues fixed/deferred, and gate results.
