Detects flooding events at USGS streamgages by fetching instantaneous (15-min) gage height data, computing daily maximums, and comparing against NWS flood stage thresholds from the official NWS All Gauges Report. Outputs a CSV of stations with flood days.
Skill Claude CodeCodex
Detects flooding events at USGS streamgages by comparing daily streamflow against historical 90th percentile thresholds using the dataretrieval package. Use when analyzing flood occurrences over a date range for a list of USGS station IDs.
Skill Claude CodeCodex
Fetches pull request and issue data from a GitHub repository using the GitHub REST API via curl/subprocess. Handles JSON output parsing, pagination, date range filtering, and error handling. Use when you need to retrieve structured PR or issue data from GitHub for analysis.
Skill Claude CodeCodex
Computes community pulse metrics from raw PR and issue data and writes a structured report.json file. Calculates PR counts by state, average time-to-merge, top contributor, bug issue counts, and resolved bugs. Use when you need to generate GitHub repository health metrics reports.

Run the General Lake Model (GLM v3) for Lake Mendota — edit glm3.nml, execute the GLM binary, parse NetCDF output (depth = zsurface - zlayer), match to field observations, compute RMSE, and iteratively calibrate Kw, swfactor, windfactor, coefmixhyp to achieve RMSE < 2°C.
Skill Claude CodeCodex
Orchestrates mass parameter grid search across approximants for GW matched filtering, tracks best SNR per approximant, handles errors gracefully, manages memory, and writes final CSV output.
Skill Claude CodeCodex
Core utility for reading GWF frame files, conditioning gravitational wave detector data (highpass filtering, resampling, cropping, PSD estimation), generating waveform templates, and performing matched filtering to extract peak SNR values using PyCBC.
Skill Claude CodeCodex
End-to-end DC Optimal Power Flow with spinning reserve co-optimization. Parses MATPOWER JSON network data, builds DC power flow model with bus voltage angles, formulates and solves the DCOPF+reserve QP/LP via cvxpy (CLARABEL solver), computes line loading and operating margins, and produces a structured report.json.
