A structured toolkit of thinking skills for Claude Code — covering logic, ethics, creativity, decision-making, systems thinking, communication, and more. Each skill is an invokable command that applies a specific reasoning framework to any situation.
Instructions for human-avatar/skills-for-humanity, covering skills-for-humanity, structure, naming convention, skill.md format and category command format.
Tests whether the parts of something form a unified whole — finding the jarring inconsistencies that accumulate when different contributors work without a shared vision. TRIGGERS: 'coherence check', 'does this feel unified', 'something feels off', 'inconsistent', 'check the whole', 'does this hang together'.
Tests whether a solution is more complex than it needs to be — distinguishing necessary complexity from accidental complexity that accreted over time. TRIGGERS: 'elegance test', 'is this too complex', 'over-engineered', 'is there a simpler way', 'does this feel right'.
Identifies the underlying formal pattern at work — because most successful designs, arguments, and solutions share deep structural patterns, and naming the pattern unlocks the playbook. TRIGGERS: 'what pattern is this', 'pattern recognition', 'why does this work', 'identify the form', 'what structure is at play'…
Finds the simpler version while preserving what matters — not arbitrary reduction, but finding the core and discarding what is not it. TRIGGERS: 'find the simple version', 'simplify this', 'what's the essence', 'less but better', 'strip it back', 'what could we remove'.
Entry point for the aesthetic toolkit. Routes to the right aesthetic skill based on your situation. Use when you say 'aesthetic', 'check the design', 'does this feel right', 'is this elegant', 'is this too complex', 'what pattern is this', 'find the simpler version', or want an aesthetic lens applied without knowing…
Finds where an analogy breaks down before it's relied upon. Analogies fail silently — the damage happens when decisions are made on a mapping that doesn't hold in the relevant dimension. Triggers: 'stress-test this analogy', 'where does this comparison break', 'does this really apply', 'test the metaphor', 'where is…
Imports solutions from unrelated domains by finding structural similarities between your problem and solved problems elsewhere. Triggers: 'cross-domain analogy', 'what solves this elsewhere', 'find a parallel problem', 'look outside this field', 'borrow a solution'.
Approaches a problem from completely different fields to break the assumption blindness that comes from domain expertise. Triggers: 'fresh eyes', 'outside perspective', 'what would a [different expert] say', 'beginner's mind', 'approach from another field'.
Identifies the deep structural correspondence between two situations — genuine isomorphism vs superficial similarity. Triggers: 'does this analogy hold', 'map the structure', 'is this really like that', 'structural similarity', 'test the comparison'.
Entry point for the analogy toolkit. Routes to the right analogy skill based on your situation. Use when you say 'analogy', 'is this like that', 'find a comparison', 'import a solution from elsewhere', 'fresh eyes on this', 'where does this metaphor break', or want analogical reasoning applied without knowing which…
Maps the attention economy of a mind or situation — what captures it, what depletes it, and how to protect it. Use when asked 'why can't I focus', 'attention keeps getting pulled away', 'how do I protect deep work', 'what's stealing my focus', 'I keep getting distracted', or when designing environments, workflows, or…
Manages the limits of working memory — chunking, offloading, and reducing unnecessary complexity to free capacity for what matters. Use when asked 'this is too complex to hold in my head', 'I keep losing track of where I am', 'how do I make this simpler to think about', 'the design is overwhelming', 'people aren't…
Surfaces and audits the internal representations that drive perception and decision-making. Use when asked 'what assumptions am I making', 'why do I keep seeing this the same way', 'what model is driving this decision', 'I think I'm missing something about how this works', 'what's my mental model here', or when a…
Applies thinking-about-thinking as a practical tool — monitoring comprehension, calibrating confidence, and knowing what you do not know. Use when asked 'how confident should I be about this', 'am I actually understanding this or just recognising it', 'what do I not know that I should know', 'I think I understand this…
Entry point for the cognition toolkit. Routes to the right cognition skill based on your situation. Use when you say 'cognition', 'how am I thinking about this', 'why can't I focus', 'what mental model is driving this', 'am I thinking clearly', 'this is too complex to hold in my head', 'what do I actually know here'…
Maps what the audience currently believes, actually cares about, and fears before communicating — because communication fails at the receiver, not the sender. Triggers: 'model the audience', 'audience analysis', 'who am I talking to', 'what do they care about', 'why aren't they getting it'.
Audits a communication for places where the message will be lost, misread, or misunderstood — before it's sent. Triggers: 'clarity audit', 'will this be understood', 'check my message', 'edit for clarity', 'where will this be misread'.
Matches the message to the right channel and format — the same content in the wrong medium loses most of its effect. Triggers: 'which channel', 'email vs meeting', 'should this be async or sync', 'medium fit', 'how should I deliver this'.
Maps likely objections before delivering a proposal — objections that are anticipated feel addressed; objections that land as surprises derail. Triggers: 'anticipate objections', 'what will they push back on', 'steelman the opposition', 'prepare for resistance', 'objection mapping'.
Entry point for the communication toolkit. Routes to the right communication skill based on your situation. Use when you say 'communication', 'how do I say this', 'will this land', 'which channel', 'what will they push back on', 'does this make sense', or want communication help without knowing which specific tool…
Tests whether a stated constraint is real — distinguishing genuine limits from assumptions, habits, or politics dressed as facts. Triggers: 'is this really a constraint', 'challenge the assumption', 'who says we can't', 'is this actually fixed', 'test the constraint'.
