Harness Explorer v0.5.0 Major release renaming the project from 'Instruction Hierarchy Explorer' (ihe) to 'Harness Explorer' (he), reflecting industry terminology convergence (Microsoft VS Code, promptfoo, PrimeIntellect). BREAKING CHANGES: - Binary: ihe → he - Go module: gitlab.com/andunn/ihe → gitlab.com/andunn/he - Container: ENTRYPOINT changed to 'he' - Update any scripts or aliases referencing the old name NEW METRICS (research-backed, all local/offline): 1. Position Importance Score - Measures instruction density in first/last 10% vs middle 80% - Based on 'Lost in the Middle' (arXiv:2307.03172) - Score >2.0 indicates good structure; ~1.0 means flat distribution 2. Negative Constraint Ratio - Ratio of NEVER/AVOID/PROHIBITED vs MUST/ALWAYS/SHOULD - Based on Claude's Character research - Balanced ratio (~0.3-0.5) suggests healthy constraint mix 3. Hedging Density - Frequency of hedging words (might, could, perhaps, generally) - Based on RLHF Length Bias research (arXiv:2310.03716) - Lower = more direct, actionable instructions 4. Specificity Gradient - Positive reframe of inheritance_violation (1 - score) - Higher = children differentiate well from parents 5. Boilerplate Lead Score - Detects files starting with generic intros vs substance - Based on Attention Sinks research (arXiv:2410.13835) - Higher = more files lead with important content UI IMPROVEMENTS: - Three-column metrics dashboard with logical groupings - Color-coded quality indicators (green/amber/red dots) - Progress bars showing relative metric values - Hover tooltips explaining each metric's meaning OTHER CHANGES: - Auto-detect .gitlab/duo/skills directory (GitLab Duo) - Auto-detect .cursor/rules directory (Cursor IDE) - CI creates proper GitLab Release with binary download links - Project logo added (assets/he.png, LFS tracked) - Unit tests for new metric functions INSTALLATION: curl -L https://gitlab.com/andunn/he/-/releases/v0.5.0/downloads/he-darwin-arm64 -o he chmod +x he CONTAINER: docker run --rm -v $(pwd):/work -p 8765:8765 registry.gitlab.com/andunn/he:v0.5.0
