# Loop Agent > Execute workflow agents iteratively for refinement and progressive improvement until quality criteria are met. Use when tasks require repetitive refinement, multi-iteration improvements, progressive optimization, or feedback loops until convergence. Use when this capability is needed. - Skill: `tomevault-io/loop-agent` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/loop-agent` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/loop-agent/raw - Safety review: pending - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/loop-agent --- # Loop Agent Skill Execute workflow agents iteratively for refinement and progressive improvement until quality criteria are met. ## Quick Reference - **[Modes](modes.md)** - Loop termination modes (fixed, criteria, convergence, hybrid) - **[Patterns](patterns.md)** - Common loop patterns (refinement, test-fix, optimization) - **[Configuration](configuration.md)** - Loop setup and templates - **[Examples](examples.md)** - Complete loop examples ## When to Use - Code needs iterative refinement until quality standards met - Tests need repeated fix-validate cycles - Performance requires progressive optimization - Quality improvements need multiple passes - Feedback loops necessary for convergence ## NOT Appropriate For - Single-pass tasks (use specialized agent) - Purely parallel work (use parallel-execution) - Simple linear workflows (use sequential) - One-time analysis ## Core Concepts ### Loop Termination Modes | Mode | Description | Use When | |------|-------------|----------| | **Fixed** | Run exactly N iterations | Known number of passes needed | | **Criteria** | Until success criteria met | Specific quality/performance targets | | **Convergence** | Stop at diminishing returns | Optimal result unknown | | **Hybrid** | Combine multiple conditions | Complex requirements | See **[modes.md](modes.md)** for detailed mode documentation and **[patterns.md](patterns.md)** for common loop patterns. --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/d-o-hub) — claim your Tome and manage your conversions.
