# negentropy-lens

Evaluates systems, architectures, and engineering choices through the lens of entropy versus negentropy. It uncovers tacit knowledge gaps and technical debt before you commit to a design.

## What it does

This skill guides the agent through five phases: mapping system boundaries, diagnosing decay versus growth, surfacing unspoken assumptions, rating compounding value, and challenging weak trade-offs. It treats inaction and unrecorded workarounds as continuous decay.

The framework explicitly pushes back against cosmetic fixes. Adding alerts to an unstable service counts as merely slowing entropy, not creating compounding order. Because of this, the assistant questions whether proposed designs fix root causes or just patch symptoms while relying on undocumented tribal knowledge.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add bencium/bencium-marketplace --skill negentropy-lens -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/negentropy-lens/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/negentropy-lens/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add bencium/bencium-marketplace --skill negentropy-lens -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/negentropy-lens/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add bencium/bencium-marketplace --skill negentropy-lens -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/negentropy-lens/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install bencium/bencium-marketplace negentropy-lens
```

2. **Manually: put the files in place**
- File: `.github/skills/negentropy-lens/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add bencium/bencium-marketplace --skill negentropy-lens -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/bencium/bencium-marketplace --path negentropy-lens/skills/negentropy-lens
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/negentropy-lens/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add bencium/bencium-marketplace --skill negentropy-lens -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/bencium/bencium-marketplace/tree/HEAD/negentropy-lens/skills/negentropy-lens/SKILL.md

## When to use it
- audit architecture proposals for hidden operational assumptions
- identify unwritten workarounds and single points of failure in team workflows
- evaluate technical trade-offs between competing infrastructure designs
- distinguish between genuine system growth and temporary decay-slowing patches

## Example prompts
- Apply the negentropy lens to our plan for splitting this monolith
- Review this service architecture and identify any tacit knowledge gaps
- Evaluate our data ingestion pipeline: where is entropy accumulating?

description: >
  A decision-support framework that evaluates systems, architectures, and strategies through the
  entropy (decay) vs negentropy (growth) lens, while surfacing tacit knowledge gaps. Use this skill
  whenever the user is making architecture decisions, evaluating system designs, reviewing technical
  approaches, choosing between options, auditing existing systems, or planning strategies. Also
  trigger when the user explicitly asks to "apply the negentropy lens", mentions "entropy",
  "negentropy", "tacit knowledge", "knowledge engine", or "flip the switch". Nudge activation
  when you detect the user is at a decision point — even if they haven't asked for this lens —
  by briefly noting the entropic/negentropic dimension before proceeding.

# Negentropy Lens

A thinking framework for evaluating decisions, systems, and architectures through two fundamental
system states: **entropy** (decay, disorder, complexity debt) and **negentropy** (growth,
compounding value, increasing order).

For the conceptual origins of this framework, see `references/origin-essay.md`.

## Core Principle

Every system exists in one of two states. Every decision either accelerates entropy or drives
negentropy. There is no neutral. Inaction is entropic. The goal is not to eliminate entropy — it
is to recognize which state a system is in, surface what is hidden, and make deliberate choices
about direction.

## Term Definitions

On first use in every output, define these three terms inline using parentheses:

- **Entropy** (the natural tendency of systems toward decay, disorder, and complexity without value)
- **Negentropy** (the deliberate reversal of decay — growth, compounding value, increasing order)
- **Tacit knowledge** (the unwritten, unspoken knowledge of how things actually work — assumptions,
  workarounds, and institutional memory that never make it into documentation)

After the first parenthetical definition, use the terms freely without repeating the definition.

## The Two States

### Entropy (Decay)
Signs of entropy in a system:
- Complexity increases without corresponding capability gain
- Knowledge lives in people's heads, not in the system
- Workarounds accumulate; the handbook diverges from reality
- Decisions optimize for slowing decline rather than enabling growth
- "Not invented here" blocks adoption of better approaches
- Technical debt compounds silently
- Integration points multiply without clear ownership

### Negentropy (Growth)
Signs of negentropy in a system:
- Each component makes adjacent components better
- Knowledge compounds — today's output improves tomorrow's input
- Quality improves through engineering discipline, not heroics
- Decisions create upward spirals: better decisions → better data → better decisions
- The system reflects how the organization actually operates
- Complexity serves capability; unnecessary complexity is actively removed
