tiger-js-cli

Three commands for a Tiger project: two read-only diagnostics, no build, no browser, just the files already on disk, and one that installs the Tiger Skill for Claude Code.

npm install -g tiger-js-cli

tiger check

The same diagnostics the VS Code extension gives a human ("no cell named taks, did you mean task?"), as a command instead of a squiggle only an editor can show:

$ tiger check
pages/tasks.html:22:14  warning  Tiger: no cell named "newTag". Did you mean "newtag"?

0 error(s), 1 warning(s)

Exits with a non-zero code on any diagnostic, error or warning, so it works as a pass/fail gate in a script or an agent loop. Add --json for structured output.

tiger map

The whole shape of the app, read once instead of pieced together file by file: every route, every component (straight from components.json), every cell and its shape, every action, every machine.

$ tiger map
routes:     home, settings, task
components: task-item, empty-state, t-tabs, t-chips, …
cells:      left, filter, search, tasks, task, draft, theme, …
actions:    addTask

--json gives the full structured version, including each cell's declared shape (task becomes { id, text, done, priority, tags }).

tiger skill install

Writes the Tiger Skill, a SKILL.md file Claude Code loads on its own once it recognizes a Tiger project (a <cells> block, a pages/ folder, a components.json), no copy, paste, or prompt engineering needed.

tiger skill install

Installs to ~/.claude/skills/tiger/SKILL.md by default, so it's available in every Tiger project you open from then on, not just the one you ran it from. Pass --project to install it into just the current project instead (.claude/skills/tiger/SKILL.md):

tiger skill install --project

Safe to run again any time: it reports installed, updated, or unchanged and only writes when something actually changed. This is Claude Code specific, it does nothing for other AI coding tools; for those, see AGENTS.md (seeded into every scaffold) or primer.md (paste into any chat).

Usage

tiger check [dir] [--json]
tiger map [dir] [--json]
tiger skill install [--project]

dir defaults to the current folder. check and map expect the usual Tiger project shape: app.html, shared.cells, pages/*.html, components/*.html, components.json, the same convention the router already uses.
