pestel-delta-monitor
Quarterly re-scan of a prior PESTEL analysis. Use when checking which macro factors moved, which assumptions broke, and what's new — turning PESTEL from a workshop artifact into a radar.
Why this skill is useful
Provides a structured workflow for refreshing PESTEL analysis, identifying material changes and broken assumptions that the AI wouldn't reliably generate on its own.

What this skill does
PESTEL Delta Monitor Purpose Refresh a PESTEL analysis by diffing each factor — Political, Economic, Social, Technological, Environmental, Legal — against the prior run and reporting material movement only: search plan → factor-by-factor diff → broken assumptions → new entrants to the frame → next-step options. Macro factors move slowly, which is exactly why teams stop looking; the value of a cadence is catching the two factors that moved, not re-debating the twenty that didn't. Diffing also reveals which baseline entries were live assumptions versus furniture — broken assumptions are the real output. Input Works best with: the prior PESTEL analysis (pasted or attached) and the product/market scope it covered — this skill requires a baseline to diff against. Also useful: any events since the last run you already suspect matter — they get checked first. Input supplied inline with the invocation — text after the skill name, a pasted context dump, or an appended ARGUMENTS: line — counts as answers already given. Use it against the question budget; don't re-ask. Arriving empty-handed? This is the one investigation skill with a hard prerequisite: with no baseline, it recommends running pestel-analysis first and stops — there is nothing to diff. (That referral is the empty-handed path: you leave knowing exactly what to do first.) Example invocation: PESTEL delta against the attached Q1 analysis — scope is our EU payments product; I suspect the new AI liability directive matters. Key Concepts Governing protocol: honors the autonomous-investigation contract — question budget of 2, search-plan gate, Fact/Inference/Assumption labels, Just Enough Mode, stable schema, 4-option Final Step. Disciplines: GEOINT/DEMOINT statistics plus FININT regulatory sources (see intelligence-collection-disciplines); this is the annual/quarterly layer of the fusion cadence. …
