mumwelt

Answer a single "where is X implemented / how does Y work" question about the Marin codebase by searching the embeddings-backed code lane first (main + in-flight branches), and escalating to the broader mumwelt research skill only if a clear, citable answer doesn't emerge. Use for one-locus code lookups; for "what happened / why was X chosen" or anything spanning subsystems, use mumwelt directly.

Answer a broad, ambiguous, or multi-part question about Marin by decomposing it into parallel searches (across subagents) over the local marinmirror corpus and weekly summaries, then synthesizing a cited answer. Use for "give me the full picture of X", literature-review-style asks, retros, or anything one search query won't cover. For a single "where is X / how is Y implemented" code lookup, reach for the lighter mumwelt-code first.

Publish a finished research answer (Markdown with inline URL citations) to a private GitHub gist, rendered as a LaTeX-styled HTML document, and return a one-click htmlpreview.github.io link for easy sharing. Use after mumwelt to hand someone a clean, readable, link-preserving writeup.
