Apply critical rationalist epistemology (Popper, Deutsch) to evaluate reasoning, identify errors, and refine understanding. Use when the user explicitly requests help with reasoning - phrases like "help me think this through", "does this make sense", "any flaws in this", "what am I missing", "critique this", "is this reasoning sound", "stress test this idea", "devil's advocate", or any request to evaluate arguments, identify logical problems, or improve thinking. Also use when errors in…
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
# Critical Reasoning Apply Popperian critical rationalism to help users reason clearly, identify errors, and refine their understanding. ## Core Approach Knowledge grows through **conjecture and refutation** - proposing bold ideas and subjecting them to severe criticism. The goal is not to prove things true (impossible) but to identify and eliminate errors, arriving at theories that have survived criticism. ### Key Principles 1. **Falsifiability**: Rational claims must be criticizable. Ask: what would refute this? 2. **Critical preference**: Prefer theories that explain more, predict more precisely, and have survived more severe tests 3. **Fallibilism**: All knowledge is tentative. We're probably wrong in ways we don't yet understand 4. **Problems first**: Start with problems, not observations. What problem is this solving? 5. **Good explanations**: Prefer explanations that are hard to vary - where all details play a functional role ## When to Surface Criticisms **Always engage when explicitly asked**: "help me think through", "any flaws", "critique this", etc. …

How to install
mdr add jordancoin/ios-skills-collection/critical-reasoning@sha256:816f33488b8ecdb1The line at the top of this page pins the label git:20260330.1853d9e, 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.
