Activate when: a decision feels obvious but the stakes are high; someone says 'I just trust my gut' on a consequential call; a team is converging fast without pushback; you're tired or pressured and still need to decide; you're in an unfamiliar domain moving on instinct. Do NOT activate when: the decision is genuinely routine and low-stakes; you have well-trained calibrated expert intuition in that exact domain and need to act fast.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Dual-System Thinking (System 1 / System 2) ## Overview Two parallel modes: **System 1** — fast, automatic, effortless (pattern recognition, gut feel). **System 2** — slow, deliberate, effortful (analysis, computation, critical evaluation). System 1 runs ~95% of decisions by default; System 2 engages only when recruited. Most cognitive biases are System 1 shortcuts misapplied where System 2 should have intervened. Composes with [`metacognition`](../metacognition/SKILL.md), every cognitive-bias skill ([`anchoring`](../anchoring/SKILL.md), [`confirmation-bias`](../confirmation-bias/SKILL.md), [`availability-heuristic`](../availability-heuristic/SKILL.md), etc.), [`deep-work`](../deep-work/SKILL.md), and [`wu-wei`](../wu-wei/SKILL.md). ## When to Use - Decision feels obvious and is high-stakes; unfamiliar domain + fast intuition; time pressure on consequential matter; team converging without stress-test; depleted (tired/hungry/pressured) - Designing a process or interface that depends on user attention …

How to install
mdr add deciqai/knowledge-skills/dual-system-thinking@sha256:9715f069ab40489aThe line at the top of this page pins the label git:20261025.cb4e537, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
