Architecture and module structure of the CAPRI model (Common Agricultural Policy Regionalised Impact). Use this skill when the user asks about CAPRI structure, module relationships, data flow between modules, directory layout, key GDX files, or how CAPRI components fit together. Trigger on mentions of CAPRI modules such as COCO, CAPREG, CAPTRD, CAPMOD, CAPDIS, the supply module, market module, Armington trade model, iterative solving, or spatial disaggregation. Also trigger when the user needs to understand which CAPRI file to edit, where data flows, or how the simulation pipeline works.
Debug CAPRI model solve failures, infeasibilities, and convergence issues. Use this skill when the user encounters a solve failure, infeasibility, locally infeasible, model status error, solver status error, CONOPT failure, NLP error, unbounded variable, convergence failure, iteration divergence, bounds violation, solve error, or needs help debugging a GAMS model that won't solve. Also trigger when the user mentions market model infeasibility, supply-market iteration problems, Armington bound issues, TRQ switching failures, dampening parameters, or any CAPRI simulation that produces unexpected solver output.
Reference guide for CAPRI environmental indicators and emissions modeling. Use this skill when the user asks about GHG emissions, greenhouse gas, nutrient balances, NPK, nitrogen, phosphorus, potassium, energy use in agriculture, environmental indicators, IPCC methodology, manure management, fertilizer allocation, ammonia emissions, emission factors, carbon cycle, carbon balance, nitrate leaching, soil erosion, N2O, CH4, CO2 from agriculture, enteric fermentation, manure storage, manure application, over-fertilization, nutrient availability, atmospheric deposition, biological fixation, crop residues, emission intensity, tradable GHG permits, livestock density limits, nitrates directive, NEC directive, mitigation technologies, anaerobic digestion, feed additives, precision farming, or CAPDIS nitrogen disaggregation. Also trigger when exploring environmental data in CAPRI GDX files or writing scenario code that involves environmental constraints.
GAMS coding conventions for the CAPRI model (Common Agricultural Policy Regionalised Impact). Use this skill whenever the user asks to write, review, refactor, debug, or generate GAMS code for CAPRI — or any GAMS code that should follow CAPRI conventions. Also trigger when the user mentions CAPRI model development, CAPRI GAMS style, "red book" conventions, or asks for help with GAMS naming, set usage, indentation, comments, error trapping, meta data, or file structuring in a CAPRI context. Even if the user just says "write GAMS code" or "review my GAMS file" and CAPRI is part of the project, use this skill. This skill encodes the official "Red Book on CAPRI GAMS Coding" by Wolfgang Britz (Bonn University).
Comprehensive reference and workflow skill for the CAPRI market module (global partial equilibrium trade model). Trigger when the user asks about trade modeling, Armington assumption, CES functions, substitution elasticities, welfare analysis, market clearing, bilateral trade flows, import demand, export supply, price linkage equations, biofuel module, TRQ (tariff rate quota), tariff modeling, market model solving, global trade, Armington aggregator, price transmission, feed demand in market model, processing industry equations, oilseed crushing, dairy processing, intervention stocks, subsidised exports, market equilibrium, or debugging infeasibilities in the CAPRI market module.
Workflow skill for creating new CAPRI modules or extending the CAPRI model. Trigger when the user asks to create a new module, add a new product, add a new commodity, add a new activity, extend the model, scaffold a new GAMS file, create a new include file, build a model extension, add a feature to CAPRI, create a GAMS file for CAPRI, or register a new data source. Also trigger for requests involving new set elements, new equations, new variables, or any structural addition to the CAPRI modelling system.
Reference guide for CAPRI policy instruments and their implementation in GAMS. Use this skill when the user asks about CAP premiums, direct payments, subsidies, Pillar I, Pillar II, rural development, greening payments, coupled support, decoupled payments, Basic Payment Scheme (BPS), Single Payment Scheme (SPS), Single Area Payment Scheme (SAPS), voluntary coupled support (VCS), national ceilings, premium cuts, TRQs, tariff rate quotas, trade policy, flexible levies, minimum import prices, tariffs, ad-valorem tariffs, specific tariffs, quotas, milk quotas, sugar quotas, set-aside obligations, WTO boxes, green box, blue box, amber box, PSE classification, Producer Support Estimate, co-financing rates, agri-environmental schemes, LFA payments, Natura 2000, ecological set-aside, crop diversity, entitlement trade, or any question about how agricultural policy is modelled, parameterised or simulated in CAPRI.
Comprehensive guide for CAPRI scenario creation, simulation design, and result interpretation. Use this skill when the user asks about designing scenarios, running simulations, baseline generation, calibration, CAPTRD projections, counterfactual analysis, comparative static analysis, policy shocks, price changes, subsidy modifications, technology shifts, welfare analysis, result interpretation, dual value decomposition, baseline reproduction runs, or any question about how to set up and evaluate a CAPRI scenario. Also trigger when the user mentions DG-AGRI Outlook, Aglink-COSIMO projections, PMP calibration, scenario GDX files, or comparing baseline vs. scenario results.
