mathematical-problem-solving · Solving proof-based and computational math problems where Polya's phases and Schoenfeld's control prevent dead-end grinding.

metacognitive-monitoring · Preventing unproductive grinding by actively checking progress every 2-5 minutes and switching strategies when stalled.

the-fool · Stress-testing decisions via pre-mortems and red teams before committing when a single bad choice carries high cost.

env-handler · Securing API keys and secrets in .env.local while distributing safe templates in .env across the team.

problem-comprehension · Avoiding misinterpreted problems by systematically identifying knowns, unknowns, constraints, and problem type before solving.

strategy-selection · Matching well-understood problems to their natural solving strategy rather than brute-forcing with trial-and-error.

find-bug-root-cause · Isolating elusive bugs using binary search and hypothesis testing rather than random code inspection or blame.

behavioral-neuroscience · Understanding brain constraints on behavior, design decisions informed by neural limits, or psychopharmacology reasoning.

clinical-foundations · Clinical practice where empirical assessment beats intuition for reliability and ethical practice.

tables · Organizing structured data where tables provide clarity and queryability.

cognitive-psychology · Understanding decision-making biases, memory constraints, or attention bottlenecks in system design.

developmental-psychology · Designing age-appropriate experiences, understanding delays, or intervening during critical periods.

angle-generator · Marketing/comms where the same fact told through different angles reaches different segments.

research-methods-psych · Psychology research where internal/external validity and replicability are non-negotiable.

social-psychology · Diagnosing why teams conform to poor decisions or explaining how organizational pressure shapes individual behavior beyond rational choice.

blameless-postmortem · Converting incidents into organization-wide learning while protecting the psychological safety required for honest incident reporting, especially in distributed systems and on-call rotations.

ecosystem-alignment · Keeping a custom Claude Code setup in sync with upstream platform updates, preventing drift and discovering new capabilities to adopt.

rca-classical-methods · Linear, single-cause shop-floor incidents (5 Whys), or multi-pathway quality incidents (Fishbone), or safety-critical system design review (FTA/FMEA) where classical techniques have proven power.

rca-human-factors · Safety-critical industries (aviation, healthcare, emergency response, nuclear) where understanding why the operator's action was reasonable from their perspective reveals system design flaws to fix.
