Bulk rotate photos in an Immich library — by album or asset IDs. Non-destructive, original files are never modified. Supports undo/revert. Use when the user says "rotate photos", "rotate album", "fix rotation", "photos are sideways", "rotate 90", "rotate clockwise", "rotate counterclockwise", "upside down photos", "wrong orientation", "bulk rotate", "rotate multiple", or any variation of wanting to rotate one or more photos.

Scan for and fix broken or missing photo metadata — dates, GPS coordinates, timezone offsets, and camera info. Detects suspicious patterns (midnight/noon timestamps, missing GPS on geotagged trips) and proposes corrections using folder structure, neighboring photos, and EXIF inference. Use when the user says "fix metadata", "fix dates", "wrong dates", "missing GPS", "metadata repair", "exif fix", "photos have wrong time", "noon dates", "midnight timestamps", "fix my photo dates", "metadata fixer", or any variation of wanting to repair photo metadata.

Analyze the photo timeline to find suspicious gaps — months or years with zero or very few photos. Helps identify failed imports, missing backups, or periods where photos exist in only one ecosystem. Use when the user says "timeline gaps", "missing months", "missing photos", "are there gaps", "what months am I missing", "photo timeline", "coverage check", "find missing periods", "when am I missing photos", or any variation of wanting to find holes in their photo timeline.

Detect and remove screenshots, duplicates, and low-quality photos from an Immich library. Use when the user says "clean up my photos", "remove screenshots", "find duplicates", "deduplicate", "photo cleanup", "library cleanup", "how many screenshots do I have", "free up space", "remove junk photos", or any variation of cleaning, deduplicating, or optimizing a photo library.

Design and execute insect population surveys covering survey design, sampling methods, field execution, specimen identification, diversity index calculation including Shannon-Wiener and Simpson indices, statistical analysis, and reporting. Covers defining survey objectives, selecting study sites, determining sampling intensity and replication, choosing sampling methods appropriate to target taxa, standardizing collection effort, recording environmental covariates, identifying specimens to the lowest practical taxonomic level, calculating species richness, Shannon-Wiener diversity (H'), Simpson diversity (1-D), evenness, rarefaction curves, multivariate ordination, and producing survey reports with species lists and conservation implications. Use when conducting baseline biodiversity assessments, monitoring insect populations over time, comparing insect communities across habitats or treatments, assessing environmental impact, or supporting conservation planning with quantitative ecological data.

Fit cognitive drift-diffusion models (Ratcliff DDM) to reaction time and accuracy data with parameter estimation (drift rate, boundary separation, non-decision time), model comparison, and parameter recovery validation. Use when modeling binary decision-making with reaction time data, estimating cognitive parameters from experimental data, comparing sequential sampling model variants, or decomposing speed-accuracy tradeoff effects into latent cognitive components.
