grafana-billing
Query Prometheus and Loki billing metrics from Grafana. Use when discussing observability costs, active series, ingestion rates, storage usage, or cardinality analysis.
julia-numerical
Execute numerical calculations and mathematical computations using Julia. Use this skill for matrix operations, linear algebra, numerical integration, optimization, statistics, and scientific computing tasks.
event-detection-temporal-intelligence-expert
Expert in temporal event detection, spatio-temporal clustering (ST-DBSCAN), and photo context understanding. Use for detecting photo events, clustering by time/location, shareability prediction, place recognition, event significance scoring, and life event detection. Activate on 'event detection', 'temporal clustering', 'ST-DBSCAN', 'spatio-temporal', 'shareability prediction', 'place recognition', 'life events', 'photo events', 'temporal diversity'. NOT for individual photo aesthetic quality (use photo-composition-critic), color palette analysis (use color-theory-palette-harmony-expert), face recognition implementation (use photo-content-recognition-curation-expert), or basic EXIF timestamp extraction.
geospatial-data-pipeline
Process, analyze, and visualize geospatial data at scale. Handles drone imagery, GPS tracks, GeoJSON optimization, coordinate transformations, and tile generation. Use for mapping apps, drone data processing, location-based services. Activate on "geospatial", "GIS", "PostGIS", "GeoJSON", "map tiles", "coordinate systems". NOT for simple address validation, basic distance calculations, or static map embeds.
drone-site-survey
Process drone survey data for construction sites. Generate orthomosaics, DEMs, point clouds, calculate volumes, track progress, and integrate with BIM models for comparison.
isru-assessment
Perform In-Situ Resource Utilization (ISRU) sizing and feasibility analysis. Use this skill to evaluate resource extraction from planetary regolith, propellant production from local materials, water ice mining, and closed-loop resource economics. Trigger for "ISRU," "in-situ resources," "regolith processing," "propellant production," "water ice extraction," "lunar mining," "Mars ISRU," "Sabatier reactor," or "oxygen from regolith."
cost-modeling
Perform parametric cost estimation and ROM (Rough Order of Magnitude) costing for space missions. Use this skill to generate lifecycle cost estimates using CERs, compare launch costs, estimate operations budgets, and support cost-driven trade studies. Trigger this for "cost estimate," "ROM cost," "mission cost," "launch cost," "cost model," "lifecycle cost," "operations cost," or whenever a trade study needs cost as a Figure of Merit.
pywayne-ahrs-tools
AHRS quaternion decomposition and roll/pitch compensation utilities. Use when working with pywayne.ahrs.tools module for quaternion to Euler angle decomposition, or compensating orientation to zero pitch and roll using roll-pitch compensation method.
cost-estimation
Perform parametric cost estimation and cost-risk analysis for space missions. Use this skill to generate ROM (Rough Order of Magnitude) costs, build Cost Estimating Relationships (CERs), produce cost breakdowns by subsystem and WBS element, and generate cost S-curves for risk assessment. Trigger this for "mission cost," "cost estimate," "ROM cost," "cost model," "cost-to-complete," "budget estimate," "proposal cost," "cost breakdown," or "cost risk."
constellation-design
Design and analyze satellite constellations and distributed space architectures. Use this skill for Walker constellation patterns, coverage analysis, inter-satellite links, orbital shell design, collision avoidance, spectrum coordination, and deorbit compliance. Trigger for "constellation," "Walker pattern," "coverage analysis," "orbital shell," "inter-satellite link," "ISL," "revisit time," "ground coverage," "mega-constellation," or "distributed architecture."
