Overview

/do-in-steps

Execute complex tasks through sequential sub-agent orchestration with intelligent model selection, meta-judge → LLM-as-a-judge verification.

Purpose - Execute dependent tasks sequentially where each step builds on previous outputs
Pattern - Supervisor/Orchestrator with sequential dispatch, parallel meta-judge + implementation, judge verification, and iteration loop
Output - Comprehensive report with all step results, judge scores, and integration summary
Key Benefit - Prevents context pollution while ensuring quality through independent, specification-driven verification

Quality Assurance

Three-layer verification: self-critique (internal) + meta-judge evaluation spec (per step) + LLM-as-a-judge (external) with iteration until passing

Pattern: Sequential Orchestration with Meta-Judge and Judge Verification

Phase 1: Task Analysis and Decomposition
         Task → Identify Dependencies → Define Step Boundaries
                     │
Phase 2: Model Selection
         For each step: Assess Complexity + Scope + Risk → Select Model
                     │
Phase 3: Sequential Execution with Parallel Meta-Judge + Judge Verification

Phase 4: Final Summary and Report
         Aggregate results, judge scores, meta-judge specs, files modified, decisions made

Usage

# Interface change with consumer updates
/do-in-steps "Change return type of UserService.getUser() from User to UserDTO and update all consumers"

# Feature addition across layers
/do-in-steps "Add email notification capability to the order processing system"

# Multi-file refactoring with breaking changes
/do-in-steps "Rename 'userId' to 'accountId' across the codebase - affects interfaces, implementations, and callers"

When to Use

Good use cases:

Changes that cascade through multiple files/layers
Interface modifications with consumers to update
Feature additions spanning multiple components
Refactoring with dependency chains
Any task where "Step N depends on Step N-1"

Do NOT use when:

Independent tasks that could run in parallel → use /do-in-parallel
Single-step tasks → use /launch-sub-agent
Tasks needing exploration before commitment → use /tree-of-thoughts
High-stakes tasks needing multiple approaches → use /do-competitively

Quality Enhancement Techniques

Phase	Technique	Benefit
Phase 3	Self-Critique	Implementation agents verify own work before submission, catching 40-60% of issues
Phase 3	Meta-Judge (`sadd:meta-judge`)	Generates step-specific evaluation rubrics, checklists, and scoring criteria in parallel with implementation
Phase 3	LLM-as-a-Judge (`sadd:judge`)	Independent judge evaluates each step against meta-judge specification; `CLAUDE_PLUGIN_ROOT` passed to both agents
Phase 3	Iteration Loop	Failed steps retry with judge feedback until passing (max 3 retries) or escalate; retries reuse same meta-judge spec
Phase 3	Context Passing	Previous step summaries (files modified, key changes, decisions) flow to next step's implementation agent; max ~200 words per step
