think-reference-class-forecasting — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited think-reference-class-forecasting (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 forecast from the inside view, building an estimate from their own plan's details, which invites optimism and the planning fallacy. This skill replaces that with the outside view: find a reference class of similar past cases, take the base-rate distribution of how they actually turned out, and anchor the forecast on that, adjusting only cautiously for genuine specifics. The output is a reference-class estimate. The honest constraint: it requires real base-rate data; inventing a distribution is worse than admitting uncertainty.
When asked to forecast with the outside view, follow these steps:
references/TEMPLATE.md.Use the template in references/TEMPLATE.md. The deliverable is the reference class, base rates, and the outside-anchored estimate as a range, not a single optimistic number.
Before finalizing, verify:
Tier S. The planning fallacy is robustly demonstrated and the outside view measurably reduces forecast error (Kahneman & Lovallo 1993; Kahneman 2011). Bent Flyvbjerg's reference class forecasting for infrastructure documented systematic overruns and has been adopted by institutions (e.g. UK guidance) - real-world validation, not only lab results. The strong evidence is from human forecasting; the AI use transfers the method, with the firm constraint that base rates must be real, not invented. Full grading: evidence/dossier.md.
