-
glebis Bundle AuditRun a corpus-scale, STATS-ONLY PII audit over a folder of session transcripts LOCALLY and produce an aggregate report — counts by type and by layer, the per-session redaction-rate distribution, document lengths, and a coarse residual proxy. Use when the user says "audit my sessions", "scan folder for PII", "how much PII across these transcripts", "PII stats for my corpus", "is my redaction holding at scale", or points at a directory of transcripts and asks how much personal data it contains. Fully local — raw text never leaves the machine; the report carries ZERO PII values, transcript substrings, or filenames (only anonymized own-NN ids and counts), so the aggregates are safe to surface. Run it on a RED (raw) corpus to size the PII, or on a GREEN (already-redacted) corpus to check residual leakage.
-
glebis Bundle Elimination ResearchThis skill should be used for elimination-style research where the user wants to choose from a shortlist of products, tools, services, vendors, or other options using explicit criteria, numeric evidence, tournament-style comparison, source/domain classification, image-supported consumer reports, raw data tables, and ownership-cost estimates for replaceable parts. Use this skill whenever the user asks to compare options, buy something, shortlist candidates, rank alternatives, generate a "don't make me think" report, or produce a full audit report with raw numeric data.
-

-
julianobarbosa Bundle PremortemRun a premortem on any plan, launch, product, hire, pricing change, strategy, or high-stakes decision. Uses Gary Klein's prospective-hindsight method — assume it already failed at a future date and work backward to surface every plan-specific cause, then produce a revised plan, mitigations, early-warning signals, and a pre-launch checklist. USE WHEN premortem this, run a premortem, what could kill this, future-proof this, stress test this plan, what am I missing here, find the blind spots, what could go wrong, am I missing anything, poke holes in this, where will this break, before I commit to this. NOT FOR adversarial attack on an arbitrary idea or argument (use RedTeam), current-state multi-perspective debate (use Council), network/system vulnerability testing (use Security), or simple feedback/factual questions. DO trigger when someone has a concrete plan or commitment where the cost of being wrong is high and the decision is still changeable.
