Activate when: seller is asking way more than buyers will pay; a founder or homeowner insists their asset is worth far more than market comps; a team refuses to cut a feature they built; a free-trial cancellation flow has more friction than signup; someone says 'I've put too much into this to sell for that.' Do NOT activate when: the valuation gap is explained by genuine information asymmetry the seller actually has; the asset is a pure commodity with a transparent live market price…
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.

How to install
mdr add deciqai/knowledge-skills/endowment-effect@sha256:57e8702023d88737The line at the top of this page pins the label git:20261025.cb4e537, 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.
