Verify a cozy build by running `cozy verify` against a target you name — a locally-built docker container (default), a running sbx sandbox, or a host checkout. The checks live in cozy-module/verify.nu. Use when you say "verify the build", "build-check", "smoke test the sandbox", "is everything wired up", "/verify-cozy docker", after building the image, or after creating a sandbox.
This skill should be used when working alongside a user in a shared Nushell terminal (e.g. the cozy sandbox) — coaching Nushell in everyday tasks and practicing literate programming with numd (executable markdown), dotnu (.nu scripts that embed their own output as `# =>` comments), REPL capture, and claude-nu session archiving. It governs interaction style: build a common space where the user runs Nushell themselves and grows fluency, instead of the agent executing everything for them. Relevant when the user says "numd," "dotnu," "teach me," "show me how," "let me run it," "literate programming," "run the code blocks in this markdown," "update the embeds," "capture this session," "keep this doc in sync," "export this claude session," "self-updating README," or asks how to document, share, practice, or verify Nushell work.
Turn the current chat into a gi canvas, or open an existing one. Use when the user says "gi canvas", "start a canvas", "переведи в канвас", "продолжим в канвасе", "open the canvas", or asks to move this conversation into a canvas document.
Reduce a canvas document to its current-state meaning, letting spent rejected paths and process scaffolding fall into git history (recoverable via `git log -p -- <doc>`). Use when the user says "distill", "git-intent-distill", or "reduce the canvas".
This skill should be used when inspecting, querying, or rewriting the user's Nushell command history. Relevant when the user asks "what did I run", "show my recent commands", "what was I trying", "find commands I ran in <dir>", "remove these history entries", "move/retag these history entries to <path>", "fix the cwd on these rows", or when you need to understand what the user has been doing in a directory by looking at their shell history.
Cut a new release for the cozy project: finalize CHANGELOG.md, create a git tag, and summarize what to do next. Use when the user says "make a release", "cut a release", "release", "bump version", "tag a release", or "prepare release".
Re-vendor modules from upstream into cozy/vendor/ and prepare atomic commits grouped by repo. Use when the user says "vendor updated versions", "I vendored, commit", "nu toolkit/vendor.nu then commit", "refresh vendor", "bump vendored modules", or "vendor the latest, commit by groups".
Create a jj (Jujutsu) commit. Use only when the user explicitly asks for a jj commit — git is the default workflow. Trigger on "jj commit", "commit with jj", "/jj-commit".
