devils-advocate
Overview
The Devil's Advocate is an intellectually rigorous stress-test designed to dismantle arguments, expose blind spots, and "steel man" opposing viewpoints. This skill replaces vague skepticism with structured adversarial analysis—using inversion, fragility detection, and probabilistic auditing to ensure a proposal can survive an unforgiving market.
Guiding Principles
Principle 1: Invert, Always Invert (Source: Munger, Poor Charlie's Almanack)
To solve a problem or test a plan, think about what would cause the opposite of the desired result. Listing all the ways a plan could fail is more effective than listing why it will succeed. (Source: Farnam Street, "Inversion")
Principle 2: Anti-Resulting (Source: Duke, Thinking in Bets)
Never judge a decision solely by its outcome. A "good" result can come from a "bad" process due to luck. The Devil's Advocate must audit the decision process, not just the projected result.
Principle 3: Fragility Detection (Source: Taleb, Antifragile)
Any proposal that relies on things "staying the same" or has non-linear downside and capped upside is fragile. Strategy should aim for "Optionality"—the ability to benefit from volatility.
Principle 4: Steel-Manning (Source: Paul Graham, "How to Think for Yourself")
Do not create a "straw man" of the opposition. Instead, build the absolute strongest version of the counter-argument. If the original proposal can't survive the "Steel Man," it is fundamentally weak.
Principle 5: The Certainty Audit (Source: Duke, How to Decide)

problem-framing
Use when beginning analytical or strategic tasks, facing undefined problems, or facing analysis paralysis—requires explicit problem definition before proceeding.
3prd-writing
Use when translating a product vision into engineering requirements—enforces the Working Backwards PR/FAQ method, requiring a customer-facing press release before any technical spec.
1executive-briefing
Crafts senior leadership communications that deliver judgment rather than activity reports, connecting directly to organizational strategy and driving clear decisions. Use when presenting to board members, C-suite executives, or senior leadership — including status updates, recommendations, and escalations.
1copy-editor
Performs line-level prose editing — pruning adverbs, activating voice, cutting redundancy, and enforcing parallel structure for concision and readability. Use when revising any written content, even if the request is just 'make this better,' 'tighten this up,' or 'clean up the writing.'
1market-context
Use when validating market timing, structural forces, or distribution moats before committing strategic resources—focuses on macro context, not individual competitor teardowns.
1business-case
Use when justifying investment, resource allocation, or strategic decisions with financial and logical reasoning to ensure positive ROI and alignment with long-term goals.
