Pestel Delta Monitor Agent Skill

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):
• Prior PESTEL to paste?
• 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.

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.

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.
