SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Automated fix loops. Each harness runs a make target, spawns sub-agents to fix failures, commits on success, reverts on exhaustion.

Pattern: .claude/harness/<name>/run + fix.prompt.md

Escalation: sonnet:think → opus:think → opus:ultrathink

History: Each harness maintains history.md for cross-attempt learning. Truncated per-file, accumulates across escalation. Agents append summaries after each attempt so higher-level models can avoid repeating failed approaches.

Core Features & Use Cases

The Harness supports running structured quality checks, linking to fix scripts, and maintaining a centralized history to guide future attempts.

Quick Start

Run a harness to execute quality checks and spawn fix sub-agents automatically.

FAQPage Schema
How do I automate software quality checks with fix sub-agents?▼

You automate quality checks by running a harness that executes a make target and spawns fix sub-agents to address failures, committing on success and reverting on exhaustion.

How does escalation work when automated fix loops fail?▼

Escalation progresses from sonnet:think to opus:think to opus:ultrathink, allowing higher-level models to leverage historical learning from history.md to avoid repeating failed approaches.

What is the pattern for structuring quality check pipelines and fix scripts?▼

The pattern uses .claude/harness/<name>/run paired with fix.prompt.md to enable reproducible quality gates by linking structured command patterns with versioned run scripts.

Can I use this automated fix loop for projects requiring structured check pipelines?▼

Yes, it applies directly to software projects requiring structured check pipelines, escalation pathways, and historical learning, satisfying metadata frontmatter and versioned run scripts for reproducible quality gates.

How do sub-agents learn from previous failed quality check attempts?▼

Each harness maintains a truncated per-file history.md for cross-attempt learning, where agents append summaries after each attempt so higher-level escalation models avoid repeating failed approaches.
