Use when ESG ratings for the same issuer disagree across MSCI, Sustainalytics and LSEG, producing a consensus score plus an explicit dispersion measure of how much the vendors disagree.
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
## When to Use
Use this skill in sustainable quantitative investing, multi-factor portfolio construction, and ESG risk overlays, when you hold ESG assessments from more than one vendor for the same issuer and need a single defensible number plus an explicit measure of how much the vendors disagree.
ESG ratings from different providers measure different things. Berg, Kölbel & Rigobon (2022, *Review of Finance* 26(6), 1315–1344) report pairwise correlations between six major raters ranging from **0.38 to 0.71**, and decompose the divergence into measurement (56%), scope (38%) and weight (6%). Because scope alone accounts for well over a third of it, the disagreement between vendors is itself information — a name the vendors cannot agree on is a name whose ESG score should not carry conviction in either direction.
This module normalizes each vendor's native scale to $[0.0, 1.0]$ using that vendor's own published band structure, computes the consensus $\bar{S}$ and the dispersion $\sigma_{\text{esg}}$, gates directional signals on both vendor coverage and vendor agreement, and carries rule-based exclusion flags through to the audit report.

How to install
mdr add himanshuj16/algo-trading-skills/esg-data-signal-research-and-vendor-comparison@sha256:ba354cd800b42b5aThe line at the top of this page pins the label v2.0.0, 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.
