think-stocks-and-flows-reasoning — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited think-stocks-and-flows-reasoning (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

People systematically misjudge accumulations. They confuse a stock (a quantity that builds up: cash, debt, a customer base, a backlog, technical debt) with the flows that change it, and infer the stock's direction from a flow's direction. The classic error: "the inflow is falling, so the stock is falling." It is not - the stock keeps rising while inflow exceeds outflow. This skill makes the structure explicit: name the stock, name its inflows and outflows separately, and reason about its trajectory from the net flow. The output is a stock-flow map. It corrects a specific, well-evidenced accumulation error; it does not claim to teach systems thinking wholesale.
When asked to reason about an accumulating quantity, follow these steps:

Before finalizing, verify:
evidence/dossier.md).Tier S. The underlying failure is robustly demonstrated: across repeated experiments, including with highly educated subjects, people misread stock/flow relationships and infer stock direction from flow direction (Sterman's accumulation experiments; Cronin, Gonzalez & Sterman 2009; Meadows, Thinking in Systems). The strong evidence is that the error is real and that making the structure explicit removes it on a given problem; it is not a claim of broad systems-thinking transfer. Evidence is from human reasoners, transferred to AI use, not AI-validated. Full grading: evidence/dossier.md.
