Source-grounded answer to a question via shape-aware retrieval against the dist-only corpus: classifies the query as a named lookup, a diagnostic, or a synthesis, then runs the right protocol (direct route via slug, task-index → distillations, or three-pass index → distillations). Stops on sub-claim coverage, not on counts.
Projects one existing verified reference onto one existing task axis, gated by a per-distillation applicability check. Produces one distillation file at `corpus.commons/{corpus}/distillations/{task}/{slug}-{task}.md`, optionally with lens-applied sections or per-lens variants. Invoked by `ingesting-resources` Pass G during new-source ingestion and by `creating-applications` during per-distillation orchestration when assembling a new application.
Identifies sources in the corpus that match a query topic, situation, or concept. Returns a list with one-line justifications for each candidate, with paths to the relevant distillations.
Run a 10–15 minute structured interview with the operator that surfaces register, current circumstance, working style, relational stance, and values, then write a self-lens spec at `{corpus}/lenses/{operator-slug}-self.md`. The lens is a named-real-person lens (per `creating-lenses`) where the named person is the operator. Delta-mode by default: skips territory already covered by global or project CLAUDE.md. Voice-mode auto-detected when the `voicemode` skill is available. The lens spec is ready for `creating-distillations` Pass G.
Runs the 9-pass ingestion protocol against a single source dropped in {corpus-root}/sources/ingest/, producing a .source.md sidecar, the converted markdown, a deep reference, a light reference, one distillation per applicable task axis, and index and image updates. On success, the input source is removed from sources/ingest/.
Audit an essay or draft for under-attribution against the library's curated corpus: surfaces the one or two closest neighbours whose work overlaps with the author's distinctive synthesis, classifies the overlap, and recommends specific provenance fixes. Not a fact-check; a build/contribute-boundary check.
Design a lens: the per-distillation modifier described in `docs/reference/vocabulary.md` that shapes a distillation through a perspective, role, or methodology stance. The skill is a single-process dialogue; the output is a lens spec at `corpus.commons/{corpus}/lenses/{lens-slug}.md`, ready to feed Pass G of `creating-distillations` when the operator decides which distillations the lens applies to.
Discovers and triages candidate sources before ingestion. Produces a triage report with licence, distribution scope, format, viability verdict, and gap-fit notes: three buckets (proceed, sample first, skip). Each `proceed` entry is shaped as ready input for `ingesting-resources`.
