Core harness library providing standardized self-verification, checkpoint management, drift detection, and audit logging utilities for all NeuroClaw skills. This is NOT directly called by users; instead, it is imported as a Python module by other skills for harness-compliant execution, validation, and reproducibility. Use this as a foundation/plugin SDK when building or enhancing other skills. Triggers: none (library import only). This skill provides: HarnessController class…

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Harness Core Library

## Overview

`harness-core` is the **base SDK / plugin library** for implementing NeuroClaw harness engineering standards across all skills.

Instead of reimplementing validation, checkpointing, logging, and drift detection in every skill, `harness-core` provides reusable, well-tested Python classes and utilities that all other skills can import and extend.

**Key design principle**: Harness-awareness is **not optional** — every data-processing, model-execution, and experiment-running skill should import from this library to achieve:
- Standardized self-verification across all skills
- Reproducible, hash-verified experiment logs
- Automatic checkpoint/resume capability
- Drift detection and anomaly alerts
- Privacy-preserving audit trails

### When to Use This Skill

**Directly**: Rarely — this is a library, not a user-facing skill.

**Indirectly (as a dependency)**: 
- When developing or modifying skills like `experiment-controller`, `run_models`, `fmri-skill`, `smri-skill`, etc.
- When using skills that have been enhanced to support harness engineering
- When integrating external tools or models into NeuroClaw (inherit harness patterns)

How to install

The exact contents, by fingerprint

mdr add cuhk-aim-group/neurodiscovery/harness-core@sha256:fe7831e467f722ca

The line at the top of this page pins the label git:20260506.86420c0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
