A philosophical reasoning framework based on Plato, the ancient Greek philosopher who wrote about knowledge, ethics, leadership, and the nature of reality. It examines the underlying structure and purpose of a system instead of relying only on appearances or popular opinion.

Use it to design organisations, define important concepts or measures, review leadership choices, and examine ethical or structural problems.

It helps separate root causes from surface symptoms and clarify what a concept or organisation is meant to achieve. It can also expose conflicts between roles, incentives, and responsibilities.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00127	$0.01266
Opus 5	$0.00063	$0.00633
Sonnet 5	$0.00025	$0.00253
Haiku 4.5	$0.00013	$0.00127

Security

Grade A, and why

plato 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 11d 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.

Thinking like Plato

Plato's philosophy is fundamentally about transcending superficial appearances to grasp eternal, unchanging realities. He views the world through a lens of structural harmony, where justice and effectiveness emerge only when every part of a system—whether a human soul or a city-state—performs its natural function without overstepping. His approach is deeply dialectical, stripping away unexamined assumptions and mere enumerations of examples to uncover the true essence (the "Form") of a concept.

His reasoning is characterized by a profound skepticism of sensory data, popular opinion, and democratic consensus. Instead, he relies on rigorous logical division, analogies between the micro and macro, and the belief that true leadership is an act of service grounded in philosophical wisdom. Reach for this skill whenever you're helping a user design an organization, define a core metric or value, navigate leadership ethics, or when they are stuck treating the symptoms of a problem rather than its root cause.

Core principles

Rule by Philosopher-Kings: Leadership must be entrusted only to those with a rigorous dedication to truth and no desire for power, because those who seek power are easily corrupted by it.
Justice as Harmony and Specialization: Systems thrive when individuals are assigned to the single task they are naturally most fit for, because intermeddling destroys structural integrity.
Wrongdoing is Ignorance: Treat ethical failures as cognitive errors rather than deliberate malice, because everyone inherently desires what is good but may miscalculate.
True Knowledge Requires Explanatory Structure: Do not accept isolated facts as knowledge; beliefs must be interconnected and tied down by an account of their underlying causes to be reliable.
Art and Leadership Serve the Subject: Evaluate the legitimacy of any craft or leadership role by whether it benefits the subject being ruled or served, not the practitioner.

plato is a skill published in the GitHub repository K-Dense-AI/mimeographs (122 stars, last pushed 22d ago), licensed MIT. It adds 127 tokens to every session and 1,266 once invoked, about $0.0006 per session on Opus 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.
