The library

environmental-geography · Identifying which environmental changes (climate vs. land use vs. water stress) dominate risk in a specific region for a specific stakeholder.

fieldwork-methods · Ground-truthing remote sensing, collecting data on unmeasured phenomena (social practice, soil chemistry), or understanding local context that maps cannot capture.

geopolitics · Understanding why territorial disputes persist or how borders structure economic/security interests when geographic location is strategically binding.

human-geography · Explaining why cities cluster where they do, why migration follows particular routes, or why cultural traits concentrate in certain regions.

stop-slop · Cleaning published or client-facing prose when writer defaults to AI-like patterns (em-dashes, vague declaratives, binary contrasts, narrator voice).

physical-geography · Forecasting how landscapes respond to tectonic uplift or climate change when physical processes (erosion, isostasy, ocean circulation) dominate.

batch-rewrite-pattern · Refactoring identical symbols across 10+ files when manual diff review would be error-prone.

decision-framework-invoker · Forcing explicit trade-off when intuitive preference conflicts with measurable outcomes (e.g., safety vs. cost vs. timeline).

portable-schema-generator · Bootstrapping validation or documentation when schema does not yet exist but examples exist.

fork · Parallel processing when branch logic is independent and thread/process overhead acceptable.

session-observatory-live · Debugging production or long-running sessions when reproducing locally is infeasible.

ui-a11y · Meeting regulatory requirement (ADA, EN 301 549) or ensuring product serves disabled users reliably.

unocss · Reducing CSS bundle size when utility-first design adopted and no dynamic styling needed.

gsd-onboard · Reducing time-to-first-contribution and catching setup failures before developer time is wasted.

gsd-preflight · Preventing mergeable but broken code from reaching CI/production.

gsd-trace · Recovering decision history and requirement evolution when project docs are scattered.

gsd-workflow · Disambiguating natural-language project requests and routing to the right GSD command.

garbage-collection · Identifying highest-leverage tech-debt cleanups with mechanical scoring rather than ad-hoc judgment.

causation-consequence · Separating immediate triggers from underlying structural causes in historical analysis.

continuity-change · Assessing whether a historical moment represents genuine transformation or surface disruption.

historical-perspectives · Reconstructing how historical actors understood their own world without imposing modern bias.

KILN_AGENT_SKILL · Deploying Tezos contracts with validation, audit, and simulation gates before mainnet.

historiography · Evaluating why different historians reach different conclusions about the same events.

oral-history · Constructing evidence-based historical arguments with explicit thesis, evidence, and counterargument.

source-analysis · Interrogating a document's authorship, purpose, and reliability before deploying it as evidence.

johnny-decimal-source-evolution · Interrogating a document's authorship, purpose, and reliability before deploying it as evidence.

food-technique-fundamentals · Substituting and improvising techniques rather than following recipes rigidly.

household-economics-and-budgeting · Automating or structuring a commonly needed workflow.

BLL.skill · Automating or structuring a commonly needed workflow.

household-systems-design · Automating or structuring a commonly needed workflow.

update-docs · Automating or structuring a commonly needed workflow.

nutrition-and-meal-planning · Automating or structuring a commonly needed workflow.

github · Automating or structuring a commonly needed workflow.

sustainable-household-pedagogy · Automating or structuring a commonly needed workflow.

time-and-motion-in-the-home · Automating or structuring a commonly needed workflow.

grammar-syntax · Comparing grammar systems across languages, diagnosing learner errors rooted in L1 transfer, teaching grammatical concepts via typological contrast

braintrust-analyze · Retrospective productivity review and loop-detection when debugging why a session got stuck or repeating the same tool calls

language-learning-strategies · Designing self-directed language programs from scratch or rescuing stuck learners by repositioning strategy selection based on their actual phase

realtime-dashboard-automation · Continuously monitoring forex swing-point signals on a public dashboard, pushing alerts to Notion, and refreshing data every 15 minutes without manual intervention

phonetics-phonology · Teaching pronunciation at the system level, debugging intelligibility problems rooted in phonetic misconfiguration, or designing ear training that targets language-specific phoneme contrasts

pragmatics-communication · Building conversational fluency beyond grammar by teaching learners to decode hidden meanings, adjust formality, and navigate face-saving in their target culture

Playwright_Web_Navigator · Extracting content from React/Vue/Angular single-page applications where static HTTP requests return empty or skeleton HTML

translation-interpretation · High-stakes translation (legal, literary, technical) where equivalence theory discipline prevents the 'invisible translator' problem of over-domestication

reloop-skill.mdx · Agents that need to send bulk outreach emails reliably without manual SMTP configuration, with built-in retry and duplicate prevention

vocabulary-acquisition · Building efficient vocabulary progressions for any language by frequency-banding the 2,000-5,000 core word families that unlock independent reading

bloom-taxonomy-and-mastery · Curriculum design where instructional clarity and testable outcomes prevent fuzzy lessons and hidden assumptions about what students should learn

constructivism-and-schema · Diagnosing why a learner is stuck (schema mismatch vs. developmental impossibility) and engineering learning situations where disequilibrium prompts productive restructuring

estate-analyze-flip · When using estate analyze flip in skill contexts.

deliberate-practice-design · When coaching skill development through structured repetition and feedback cycles.

prs · When developing command-line tools in Rust with clean architecture.
