Use when the user mentions a .twbx or .twb file, a Tableau workbook or dashboard, or asks what a calculated field depends on, what would break if a field changed, which fields are unused or duplicated, why a workbook is slow, what SQL a workbook runs, or how two versions of a workbook differ.
Use this skill when a source schema change has broken, or is about to break, a downstream transformation and the user wants a fix they can merge — not a summary. Triggers on: "a column was renamed, fix the dbt model", "this field is gone downstream", "schema drift", "our model still selects the old column", "generate…
Use this skill for data incidents and for DataHub questions large enough that loading the metadata would flood the context window. It does two things: myceliumtriage produces a complete on-call report for an alert — cause, severity with its inputs, blast radius, owner, next actions, and what could not be determined…
Verify and rights-safely project LiquiLens Evidence Carrier or Fleet Brief JSON in local files.

Traces the downstream blast radius across all lineage hops, resolves owners, ranks by criticality, writes a structured incident report, and records the incident back into the catalog (tag + runbook document + native incident). Use when a table, view, dashboard, or…
