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.

Materiality for macro factors: regulation passed or credibly proposed, macro indicators

crossing thresholds your baseline named, technology maturation with adoption evidence, social
signals with data behind them. "No material movement" per factor is a valid and common result —
a quiet quarter reported honestly keeps the radar trusted.

Broken assumptions are the headline. A baseline entry now contradicted by evidence outranks

ten new observations, because strategy was built on it. The diff exists to find these.

Assumptions vs. furniture. Entries that never move and touch no decision were furniture —

flag them for retirement at the next baseline refresh rather than re-scanning them forever.

Scope changes break diffs. New market, pivot, fundamentally different business context → redo

the full PESTEL; never diff across a scope change.

Do-not-invent list: regulations, statistics, dates, events. Real URLs and dates on everything —

invented regulation is this domain's signature fabrication risk.

Application

Check the prerequisite. No prior PESTEL → recommend pestel-analysis

and stop. Scope changed since the baseline → recommend a fresh full analysis and stop.

Credit inline context, then ask only the unanswered questions (max 2):

1. Prior PESTEL to paste?
2. Any events since then you already suspect matter?

Read the prior analysis fully; diff factor by factor — the baseline document is the diff

target, not your general knowledge of the macro environment.

Show the 3-bullet search plan — which factor categories get active searching this cycle

(suspected events first), source types (government and regulatory sources, central-bank and
statistical data, credible news, industry bodies, standards organizations), fact/inference
separation. Continue unless revised.

Emit the schema below exactly.

Output schema (do not reorder)

PESTEL Delta Report

1. Run Header

Scope (from prior analysis): | Prior analysis date: | This run date:

2. Factor-by-Factor Delta

For each of P / E / S / T / E / L:

[Factor]: [moved / no material movement]

What moved: [1-2 bullets, labeled, cited — only if moved]

Prior assumption affected: [which entry from the baseline]

Reading: [Inference — implication for the product scope]

Keep "no material movement" factors to a single line each.

3. Broken Assumptions

[Baseline entries now contradicted by evidence — the run's most important section; cited]

4. New to the Frame

[Factors absent from the baseline that now warrant a slot]

5. So What?

3 implications for strategy or roadmap

2 factors to watch closely next cycle

3 assumptions to validate

Each bullet: label, confidence, URL where relevant.

A copy/paste fill-in version of this schema, with quality checks, lives in template.md.

Final Step (offer exactly 4 options)

Update the baseline PESTEL with these deltas (new baseline)

Deep-dive the most consequential moved factor

Trace the broken assumptions into roadmap or OKR impact

Set next cycle's watch priorities

Accept 1, 2, 3, 4, 1 and 2, Verbose Mode, or a custom path.

Examples

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.

See examples/sample.md for a complete worked delta run (fictional
trades-software scope) with two broken assumptions traced to their baseline entries and furniture
flagged for retirement. examples/sample-industrial.md runs the
industrial scope, where the hot factors swap — tariffs, energy, disclosure rules — and threshold
crossings are distinguished from broken assumptions.

Common Pitfalls

Re-debating the unmoved. Rewriting all six factors every quarter turns the radar back into

the workshop it was meant to replace. One line per quiet factor — the discipline is the product.

Materiality inflation. Promoting think-pieces and proposals-going-nowhere into "movement."

The bar is passed/credibly-proposed regulation, crossed thresholds, adoption evidence — not
discourse.

Burying broken assumptions. Listing deltas without connecting them to the baseline entries

they contradict. The "prior assumption affected" line is what makes a delta actionable.

Diffing across a pivot. The business entered a new market and the monitor keeps diffing the

old scope's factors. Scope change = new baseline, always.

Invented specificity. A regulation name, effective date, or statistic that doesn't check out.

In this domain a fabricated citation isn't just wrong, it's a compliance risk for the reader —
the do-not-invent list is load-bearing.
