pareto-principle

pareto-principle is a skill for Claude Code, Codex from ConrayGambit/Strategy-Consultant-5-Consulting-Frameworks. It costs 73 tokens per session (1,028 once invoked), scanned A, original, MIT.

A prioritisation method that identifies the small share of inputs responsible for most results, often called the 80/20 rule.

In plain words
What is it for?
Choosing the most important customers, products, causes, or tasks to focus on when time or resources are limited.
Why use it?
It helps decide what deserves attention first and explicitly sets lower-impact work aside.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

pareto-principle scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Pareto Principle (80/20)

Concept

In most systems, ~80% of the outcome comes from ~20% of the inputs. Strategy consultants use this constantly: figure out which 20% of customers, products, channels, or root causes drive the lion's share of impact, and ignore the rest until later.

The discipline isn't naming the vital 20%. It's having the spine to explicitly deprioritize the 80%. If everything is important, nothing is.

Required output format

Two parts, in this order:

  1. A Markdown blockquote naming the vital 20%.
  2. A bulleted list under "Actively deprioritized (the 80%):" naming what's being set aside.
> **The vital 20%:** [Specific factors/segments/causes that drive the majority of impact.]

**Actively deprioritized (the 80%):**
- Item 1
- Item 2

Defaults & flex points

Default When to flex
1–4 items in the vital 20% If the 80/20 genuinely points to one thing, use one. Don't pad.
5–10 items in the deprioritized list List enough to make the deprioritization visible — but if there are only 3 real alternatives, list 3.
Specificity in the vital 20% Don't flex — "our top customers" is too vague. Name them.
Explicit deprioritization Don't flex — implicit deprioritization is no deprioritization.

The hardest discipline: writing down something that genuinely matters into the deprioritized list. If your 80% list is full of things that don't matter, you haven't really prioritized. Real Pareto says: "Yes, X matters. We're not doing X this quarter."

Example — engineering tech debt

Problem: A mid-stage SaaS engineering team has 47 tracked tech-debt items. Leadership wants a focused six-month plan.

The vital 20%: Three items account for ~80% of incident pain and velocity drag: (1) the legacy auth middleware causing 60% of P2 tickets and forcing every new feature to add custom session handling, (2) the deploy pipeline averaging 47 minutes (preventing the team's stated daily-deploy cadence), and (3) the absence of integration tests on the billing module (the source of 4 of the last 6 customer-impacting incidents).
