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.

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.
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.)

A factor that moved, traced to its assumption (fictional):
> ### Legal: moved
> - What moved: the data-residency provision cleared committee with an 18-month compliance
> window — Fact ([legislature record, URL, date])
> - Prior assumption affected: baseline entry L2 assumed "no residency mandate before 2028,"
> which justified deferring the regional storage architecture
> - Reading: the deferral logic is dead — Inference: the architecture decision moves from
> someday to next two roadmap quarters, and compliance becomes a sales asset in regulated verticals
> before it's a legal obligation.
A quiet quarter reported honestly: five factors show "no material movement" at one line each;
one Economic entry moved (a rate-path shift crossing the baseline's stated budget-gate threshold).
The report is half a page. That brevity *is* the radar working — the reader spends two minutes and
knows the strategy's macro floor held except where it didn't.
