Skill Claude CodeCodex
Use this skill when building, running, calibrating, validating, or diagnosing SWAT+ hydrological models. Triggers include SWAT+, watershed modeling, streamflow simulation, hydrograph calibration, USGS discharge matching, routing failures, and outlet selection debugging.
Agent
When an AI agent operates swatplus-builder, it works under an explicit division of authority. This contract is what makes agent-operated runs trustworthy: the agent's capabilities are real, but bounded.
Agent
AI-Hydro is a VS Code–integrated agentic hydrology platform. swatplus-builder integrates with AI-Hydro as both an MCP server (13 tools available to the agent) and a registered skill (the agent loads SKILL.md to understand the system before touching tools).
Agent
Agent "mcp-server" from AI-Hydro/swatplus-builder, covering mcp server, start the server, register it with an agent client, tool input shape (req wrapper) and teach the agent the system: skill.md.
Agent
The MCP server exposes 13 typed tools in three tiers. The names below are the exact tool names registered in src/swatplusbuilder/mcp/server.py.
Skill Claude CodeCodex
Separate baseflow from total streamflow using digital filter and recession analysis methods.
Skill Claude CodeCodex
Parallelizes analysis across multiple USGS gauges or sites using sub-agent delegation. Orchestrates data fetching, signature extraction, and summary synthesis for a list of sites. Use when the researcher asks to "analyze all these gauges", "run this on the whole list", or "batch process these sites".
Skill Claude CodeCodex
Diagnose hydrological model calibration quality using NSE, KGE, FDC matching, and residual analysis; identify structural deficiencies.
Skill Claude CodeCodex
End-to-end workflow for authoring a multi-module AI-Hydro course: interview the user for audience and goals, propose a module breakdown with an explicit prerequisite graph, scaffold the files via the coursescaffold tool, then author each module's body. Use when the user asks to "build a course", "create a curriculum"…
Skill Claude CodeCodex
Computes standardized drought indices (SPI, SPEI) from forcing data. Identifies drought onset, severity, and duration for impact assessment.
Skill Claude CodeCodex
Fit flood frequency distributions and compute return-period quantiles from annual maximum series.
Skill Claude CodeCodex
Create interactive HTML playgrounds for exploring hydrological data — parameter sensitivity explorers, gauge comparison dashboards, return-period calculators, and catchment signature browsers. Use when the user asks for an interactive explorer, dashboard, playground, or visual tool to explore hydrological data or…
Skill Claude CodeCodex
Guide the agent to create new AI-Hydro MCP tools — Python @mcp.tool() functions that extend the platform's hydrological analysis capabilities. Use when the user wants to add a new tool, wrap a hydrology library, expose a new data source, or build a custom analysis function for the AI-Hydro MCP server.
Skill Claude CodeCodex
Create new AI-Hydro workflow skills and iteratively improve them. Use when the user wants to capture a hydrological workflow as a reusable skill, turn a completed analysis into a SKILL.md, author a new skill from scratch, or improve an existing skill's instructions or triggering accuracy.
Skill Claude CodeCodex
Create publication-quality hydrological figures — hydrographs, flow duration curves, Budyko plots, exceedance probability charts, spatial maps, and multi-panel diagnostic displays. Use when the user asks for a plot, chart, figure, visualization, or wants to create a visual for a report, paper, or presentation. Applies…
Skill Claude CodeCodex
Create production-grade AI-Hydro interactive learning modules — self-contained HTML files with executable Python cells, sliders, quizzes, scrollytelling, real AI-Hydro branding (animated gradient droplet logo, dark theme, cyan accent, Poppins/Nunito/Quicksand fonts), peer-reviewed citations, full provenance footer…
Skill Claude CodeCodex
Guide the selection of the appropriate hydrological model (conceptual vs neural) based on catchment type, data availability, and modelling purpose.
Skill Claude CodeCodex
Interpret hydrological signatures extracted from streamflow to characterise catchment behaviour and diagnose anomalies.
Skill Claude CodeCodex
Analyzes snowpack and snowmelt dynamics using SNOTEL or gridMET data. Computes Snow Water Equivalent (SWE) trends, melt timing (center of mass), and rain-on-snow event frequency.
Skill Claude CodeCodex
Use this skill when building, running, calibrating, validating, or diagnosing SWAT+ hydrological models. Triggers include SWAT+, watershed modeling, streamflow simulation, hydrograph calibration, USGS discharge matching, routing failures, and outlet selection debugging.
Skill Claude CodeCodex
Estimates streamflow for ungauged sites by transcribing data from hydro-chemically or geomorphically similar donor basins (Regionalization).
Skill Claude CodeCodex
End-to-end watershed characterisation — delineation, terrain analysis, land cover, soils, hydrological signatures, and CAMELS attributes.
