-
trecek Skill Make Experiment DiagInteractive selection of experimental design lens for visualizing experiment methodology. Routes to the appropriate exp-lens-* skill.
-
trecek Skill Exp Lens Fair ComparisonCreate a comparison fairness matrix assessing whether alternatives are evaluated under symmetric constraints. Fairness lens answering "Are alternatives compared under symmetric constraints?"
-
trecek Skill Exp Lens Estimand ClarityCreate Estimand Clarity experimental design analysis decomposing the implicit estimand from code vs. explicit claims from prose. Evidential lens answering "What exactly is the claim?"
-
trecek Skill Exp Lens Severity TestingAnalyze severity of experimental tests — adversarial cases, negative controls, falsification tests, easy-pass detection, and confirmatory theater. Falsificationist lens answering "Would this design have caught the error?"
-
trecek Skill Exp Lens Unit InterferenceCreate Unit Interference experimental design diagram showing unit hierarchy, cluster structure, shared resources, and SUTVA violation pathways. Causal-Structural lens answering "What is the unit, and can treatments spill over?"

-
trecek Skill Exp Lens Measurement ValidityAnalyze measurement validity for experimental design — auditing metric-construct alignment, proxy validity, reliability, sensitivity, and consequential validity. Argumentative lens answering "Do measurements justify the interpretation?"
-
aeyeops Bundle Cowork MigrateUse when moving, importing, copying, or migrating a Claude Cowork session, conversation, or project from one Windows machine to another, or when troubleshooting symptoms of a broken import like "session shows blank", "only the latest messages show", "scratchpad files don't open", "can't scroll past the last compaction", or "Loaded N messages (truncated via tail/compaction)" in the Cowork log. Delivers full history, working file links, and no truncated-transcript rendering bug, handling the undocumented two-layer compact_boundary truncation filter in app.asar that silently clips imported transcripts. Covers orphan sessions on Windows to Windows under the same Cowork account. Does not handle Cowork Spaces/Projects, Linux/macOS, or cross-account migration.
-
aeyeops Skill Ultrareview FixUse when working through the findings of a preceding ultrareview validation — systematically addressing the reported errors, alignment issues, gaps, and improvements by priority and applying each fix to the plan or the code. Trigger phrases include "ultrareview-fix", "fix the review findings", "address the ultrareview", and "apply those fixes". Expects an ultrareview summary in the conversation; the `ultrareview` skill produces it.
-
aeyeops Bundle Ultrareview LoopUse when a plan or a code change should go through a code review loop that keeps reviewing and fixing until no actionable findings remain: PR review before merge, plan review before implementation, or validation after a refactor. Runs /ultrareview, applies /ultrareview-fix to the findings, and re-reviews until the review passes or the iteration cap is reached. Unlike a single-pass reviewer, the loop closes its own findings. Usage: /ultrareview-loop [focus_area] [--max-iterations N].
-
