Orchestrate Batch Refactor

Selective Reading Rule

Start with:

• references/usage-routing.md
• references/quality-checklist.md

Then load only the inherited docs, scripts, assets, or examples that match the user's actual task.

Selective Reading Rule

Start with:

• references/senior-master-standard.md

Then load only the references, scripts, assets, or examples needed for the user's actual task.

Overview

Use this skill to run high-throughput refactors safely. Analyze scope in parallel, synthesize a single plan, then execute independent work packets with sub-agents.

When to Use

• When a refactor spans many files or subsystems and needs clear work partitioning.
• When you need dependency-aware planning before parallel implementation.

Inputs

• Repo path and target scope (paths, modules, or feature area)
• Goal type: refactor, rewrite, or hybrid
• Constraints: behavior parity, API stability, deadlines, test requirements

When to Use Parallelization

• Use this skill for medium/large scope touching many files or subsystems.
• Skip multi-agent execution for tiny edits or highly coupled single-file work.

Core Workflow

1. Define scope and success criteria.
   • List target paths/modules and non-goals.
   • State behavior constraints (for example: preserve external behavior).
2. Run parallel analysis first.
   • Split target scope into analysis lanes.
   • Spawn explorer sub-agents in parallel to analyze each lane.
   • Ask each agent for: intent map, coupling risks, candidate work packets, required validations.
3. Build one dependency-aware plan.
   • Merge explorer output into a single work graph.
   • Create work packets with clear file ownership and validation commands.
   • Sequence packets by dependency level; run only independent packets in parallel.
4. Execute with worker agents.
   • Spawn one worker per independent packet.
   • Assign explicit ownership (files/responsibility).
   • Instruct every worker that they are not alone in the codebase and must ignore unrelated edits.
5. Integrate and verify.
   • Review packet outputs, resolve overlaps, and run validation gates.
   • Run targeted tests per packet, then broader suite for integrated scope.
6. Report and close.
   • Summarize packet outcomes, key refactors, conflicts resolved, and residual risks.

Work Packet Rules

• One owner per file per execution wave.
• No parallel edits on overlapping file sets.
• Keep packet goals narrow and measurable.
• Include explicit done criteria and required checks.
• Prefer behavior-preserving refactors unless user explicitly requests behavior change.

Planning Contract

Every packet must include:

1. Packet ID and objective.
2. Owned files.
3. Dependencies (none or packet IDs).
4. Risks and invariants to preserve.
5. Required checks.
6. Integration notes for main thread.

Use references/work-packet-template.md for the exact shape.

Agent Prompting Contract

• Use the prompt templates in references/agent-prompt-templates.md.
• Explorer prompts focus on analysis and decomposition.
• Worker prompts focus on implementation and validation with strict ownership boundaries.

Safety Guardrails

• Do not start worker execution before plan synthesis is complete.
• Do not parallelize across unresolved dependencies.
• Do not claim completion if any required packet check fails.
• Stop and re-plan when packet boundaries cause repeated merge conflicts.

Validation Strategy

Run in this order:

1. Packet-level checks (fast and scoped).
2. Cross-packet integration checks.
3. Full project safety checks when scope is broad.

Prefer fast feedback loops, but never skip required behavior checks.

Limitations

• Use this skill only when the task clearly matches the scope described above.
• Do not treat the output as a substitute for environment-specific validation, testing, or expert review.
• Stop and ask for clarification if required inputs, permissions, safety boundaries, or success criteria are missing.
