Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00146 | $0.01794 |
| Opus 5.5 | $0.00058 | $0.00718 |
| Sonnet 5.5 | $0.00029 | $0.00359 |
| Haiku 4.5 | $0.00015 | $0.00179 |
Grade A, and why
negentropy-lens 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 2mo 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.
How it starts
The opening of the file, as written. The whole thing — 174 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

negentropy-lens is a skill published in the GitHub repository bencium/bencium-marketplace (484 stars, last pushed 1mo ago), licensed MIT. It adds 146 tokens to every session and 1,794 once invoked, about $0.0006 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
