Activate when: user asks about starting early vs. later for savings/investing, wonders if small consistent gains add up, wants to know how long to double money, is evaluating long-term wealth or skill-building decisions, mentions 'Rule of 72' or 'exponential growth.' Do NOT activate when: the time horizon is short (under 3 years) and compounding is negligible; the underlying process is genuinely linear with no reinvestment or accumulation.

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
# Compound Interest ## Overview Compound interest: a quantity grows at a rate proportional to its current size — growth itself grows — producing exponential accumulation. Formula: A = P × (1 + r)^t. Humans underestimate long-horizon outcomes because cognition extrapolates linearly. Two consequences: **Rule of 72** (doubles in ≈ 72/r periods); **late-period dominance** (most final value comes from the last few periods). Composes with [`lindy-effect`](../lindy-effect/SKILL.md), [`hyperbolic-discounting`](../hyperbolic-discounting/SKILL.md), [`expected-value-and-kelly`](../expected-value-and-kelly/SKILL.md), [`network-effects`](../network-effects/SKILL.md), [`deep-work`](../deep-work/SKILL.md). ## When to Use - Evaluating any long-horizon investment, savings, or wealth decision - Deciding between starting earlier vs. starting later; intensity vs. duration paths - Evaluating compound advantages in business (data, brand, switching cost) - Weighing AI capex, AI adoption timing, or defending against AI-native competition — where data flywheels, ecosystem lock-in, and eval/technical debt compound over years …

How to install
mdr add deciqai/knowledge-skills/compound-interest@sha256:96580d0d71557b09The 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.
