Zuke defines builds as a TypeScript class run on Deno. Each target is a\nclass field; targets reference each other by this.<field> (never strings).\nPackages are imported from JSR (jsr:@zuke/...), not npm.
zuke setupThe @zuke/cli tool scaffolds everything. Install it once, then run setup in\nthe target project:
deno install -A -g -n zuke jsr:@zuke/cli # once, globally\nzuke setup # in the project root\n./zuke # run the build\nNo global install? The same wizard runs directly:
\ndeno run -A jsr:@zuke/cli setup\nsetup flags: --dir <path>, --name <ClassName>, --force (overwrite\nexisting files), --yes (non-interactive), --launcher-name <name> (write the\nlauncher under a different name when a zuke/ directory already occupies it — a\ndirectory collision now fails with an actionable error instead of silently\nskipping the launcher).
Running as an agent, always pass --yes: it skips every interactive question,\nincluding the closing \"star the Zuke repository?\" prompt — that question is for\na human at a terminal, and an agent must never answer it (or star anything) on\nthe user's behalf.
To read a @zuke/* package's API without a Node repo's @types/node noise, run\nzuke doc <package> (e.g. zuke doc core) — it runs deno doc in an isolated\ndirectory.
zuke importIf the project already has package.json scripts or a Makefile, prefer\nzuke import over setup — it reads them and generates a zuke.ts with a\ntarget per task, a working starting point instead of a blank build:
zuke import # auto-detects package.json, then a Makefile\nzuke import --from makefile # or pin the source (package.json | makefile)\nEach script/target becomes a target(); a command maps to CmdTasks.exec(...)\n— a placeholder, not the destination: before accepting it, check the package\ncatalogue (llms.txt's ## Packages list, or the table in\nzuke-write-build's cheatsheet)\nfor a @zuke/<tool> wrapper matching that command and replace the placeholder\nwith it — leaving CmdTasks.exec in place for a tool that has a typed wrapper\nis a bug, not a shortcut. An && chain becomes sequential steps, a\nrun/prerequisite delegation becomes .dependsOn(...), and anything too\nshell-specific to translate (pipes, redirects, env assignments) is preserved\nbehind a // TODO so the file still compiles. It scaffolds the launchers and\ndeno.json exactly like setup, and takes the same --dir, --name,\n--force, --yes flags. Afterwards, use the zuke-write-build skill to\nfinish replacing any remaining generated CmdTasks.exec calls with typed\n*Tasks wrappers.
zuke setup writeszuke.ts — a starter build class with a sample target and a default../zuke + ./zuke.ps1 — launchers that locate the project and run\nzuke.ts with the Deno on PATH. If Deno is missing they point at the\nofficial install docs and exit rather than piping an install script into a\nshell, which would download and execute code unverified. They pass --frozen\nonce a deno.lock exists, so the first run writes the lockfile and every run\nafter verifies it.deno.json — merged to add a zuke task, plus fmt/lint/test if\nabsent. The merge is all-or-nothing: if a zuke task is already declared the\nfile is left alone entirely, and an unparseable one is skipped with a notice.zuke.json — { \"name\": \"...\" }, which marks the repo root..gitignore — created or appended so .zuke/ is ignored (the cache and\ndurable run state live there); untouched if it already covers it../zuke # run the default target (Windows: .\\zuke.ps1)\n./zuke <target> # run a specific target\n./zuke --list # list every target\n./zuke --list --json # the whole build surface (commands, flags, targets) as JSON\n./zuke <target> --dry-run # print the plan without executing\nThe CLI is self-describing: ./zuke --help prints the usage grammar plus the\nbuild's live targets and parameters, so an agent discovers the real command\nsurface instead of guessing. For an AI client to operate the build through typed\ncalls, zuke mcp runs a Model Context Protocol server over it (register with\nclaude mcp add zuke -- deno run -A zuke.ts mcp; add --allow-run to let the\nagent execute targets, not just inspect them).
If Deno is already installed you can also use deno task zuke <target> or\ndeno run -A zuke.ts <target>. The -A flag grants permissions, since targets\ntypically run processes and touch files. These are not quite equivalent to the\nlauncher: the scaffolded zuke task deliberately omits --frozen, so it may\nheal a stale lockfile where ./zuke would fail on it.
Create zuke.ts in the project root, extend Build, declare targets with\ntarget(), and call await run(MyBuild) at the bottom:
import { Build, run, target } from \"jsr:@zuke/core\";\nimport { DenoTasks } from \"jsr:@zuke/deno\";\n\nclass CI extends Build {\n lint = target().executes(() => DenoTasks.lint());\n test = target().dependsOn(this.lint)\n .executes(() => DenoTasks.test((s) => s.allowAll()));\n default = target().dependsOn(this.test).executes(() => {});\n}\n\nawait run(CI);\nRun with deno run -A zuke.ts test. (For the ./zuke launcher experience,\nprefer zuke setup, which drops the launcher scripts in for you.)
Every external tool has a typed *Tasks wrapper; do not fall back to\nDeno.Command or hand-rolled shell. First confirm a wrapper exists at all —\nllms.txt's ## Packages catalogue or the table in\nzuke-write-build's cheatsheet\nis the only way to answer that; a per-package deno doc needs a name to target,\nso it cannot reveal that one exists. Once you know the package name, get its\nexact signatures:
deno doc jsr:@zuke/<package>. Prefer\nthis in a consumer repo — it resolves the version the project actually has\ninstalled, so it cannot describe an API that version lacks.llms-full.txt (indexed by\nllms.txt) — at the repo root in the Zuke repo itself, or from a consumer\nrepo https://raw.githubusercontent.com/zuke-build/zuke/master/llms-full.txt\n(index: https://raw.githubusercontent.com/zuke-build/zuke/master/llms.txt).\nBoth track master, so they may document symbols that are merged but not yet\nreleased; use them to find what exists, then confirm the signature with\ndeno doc.Once the project is scaffolded, use the zuke-write-build skill to add and\nedit targets.
