Analyze SEM images for periodicity and particle sizing using micro.sem_fft. Use when user uploads an SEM image or asks about nanostructures, LIPSS, ripples, gratings, FFT analysis, periodicity, spatial frequency, particle size, grain size, or diameter distribution. Covers magnification reading, file identification, parameter selection, and result presentation.
Use when the user wants to maintain daily Bilibili creator digests through the external PulseDeck repository and a local Obsidian bilibili vault.
This skill covers causal inference methods in observational and quasi-experimental settings. Use when the user is implementing, choosing between, or debugging causal identification strategies — including instrumental variables, difference-in-differences, regression discontinuity, synthetic control, or matching estimators. Triggers on "causal effect", "identification strategy", "instrumental variable", "2SLS", "GMM", "difference-in-differences", "DiD", "staggered treatment", "regression discontinuity", "RDD", "synthetic control", "matching", "propensity score", "IPW", "AIPW", "doubly robust", "LATE", "ATT", "ATE", "parallel trends", "exclusion restriction", "first stage", "weak instruments", or "endogeneity".
Orchestrator checklist to verify worker outputs against the approved plan before accepting artifacts. Phase 2 of orchestrator/worker context enforcement (#2020).
Implements snapshot/golden file tests with temporal normalization so tests don't break daily. Use when implementing tests that compare output against expected snapshots.
Collect volatile forensic evidence from a compromised system following order of volatility, preserving memory, network connections, processes, and system state before they are lost.
Self-improving review loop for Ralph Wiggum skills. Reviews skills against best practices, implements improvements, and continues until two consecutive clean reviews. Use when validating or improving the ralph-prompt-* skill suite.
Use when a PR/MR already exists and needs to be driven to merge — monitors CI/CD, handles multi-round code review, responds to and resolves reviewer comments, and loops until all merge requirements are met.
Moves an object to one of two destination containers based on a numeric threshold check. Trigger after a measurement (e.g., temperature) is taken. Place object in 'green' box if value > threshold, or 'blue' box if value < threshold.
Audit logging for compliance and security. Structured audit events, immutable logs, user action tracking, database change tracking, and regulatory compliance (SOC2, HIPAA, GDPR). USE WHEN: user mentions "audit log", "audit trail", "activity log", "change tracking", "compliance logging", "who changed what", "SOC2 logging" DO NOT USE FOR: application logging - use logging skills; error tracking - use observability skills
Extracts learnings from completed work, feedback, or failures. Updates a persistent learnings file with capped entries. Use after receiving feedback, fixing bugs, or completing complex tasks.
Schirmer tear test values and interpretation, fluorescein staining, tonometry with normal IOP ranges, common conditions by species (KCS, glaucoma, cataracts, ulcers, entropion, cherry eye), breed predispositions.
Archive a completed change in the experimental workflow. Use when the user wants to finalize and archive a change after implementation is complete.
Acquire and analyze mobile device data using Cellebrite UFED and open-source tools to extract communications, location data, and application artifacts.
Check for meaning firewall violations - kernel crates must never import domain crates
Implement NextDNS as a zero trust DNS filtering layer with encrypted resolution, threat intelligence blocking, privacy protection, and organizational policy enforcement across all endpoints.
