nmt-upgrade — update to the latest canon + skills

Installed-suite Canon anchor. When this Skill is installed with the full suite, the bundled Canon is available at ../nmt-chat/references/Next-Move-Theory-Canon/. This packaging pointer does not change the Legacy updater's project-root target.

Re-runs the official Next Move Theory installer from the project root. The installer clones the public repo (zamesin/Next-Move-Theory-Canon-and-Skills, branch main) and refreshes, in place:

• Next-Move-Theory-Canon/ — the canon
• .claude/skills/nmt-* — Claude skills (invoke with /nmt-…)
• .agents/skills/nmt-* — Codex skills (invoke with $nmt-…)
• the <!-- Next-Move-Theory-Rules:start … end --> block in CLAUDE.md and AGENTS.md
• NextMoveTheory-README.md

It is idempotent and safe — it replaces the canon, skills, marked rules block, and README in place, leaves your own files untouched, and does not delete unrelated skills already in .claude/skills or .agents/skills.

Count this run (best-effort, ≤2s, never blocks). Unlike the other skills, nmt-upgrade has no end-of-run version check — that would be circular, since it is the updater — so without this it isn't counted in the anonymous launch analytics. As your first action, fire a one-off registration ping so the run is counted, then continue with the steps below (on any error or timeout, ignore it):
v="$(cat .nmt-version 2>/dev/null)"; curl -fsSL --max-time 2 "https://nextmovetheory.com/version?skill=nmt-upgrade${v:+&v=$v}"; >/dev/null 2>&1 || true

Steps

1. Locate the project root — the folder that contains Next-Move-Theory-Canon/

and/or .claude/skills/. That is where the canon + skills must be refreshed. If the current directory is not it, ask the user which directory to upgrade.

1. Run the installer from that directory:

``bash curl -fsSL https://nextmovetheory.com/install.sh | bash ` (Windows / PowerShell: irm https://nextmovetheory.com/install.ps1 | iex`.)

1. Report what changed. Show the installer's final summary. If the project is

a git repo, run git status --short and list which canon files / skill folders were added or modified so the user sees exactly what the upgrade pulled in.

1. Confirm done. Tell the user the upgrade is complete and that any

new/updated skills are available immediately (e.g. /nmt-diagnose, /nmt-chat). No restart is needed.

Notes

• Best-effort. The installer needs curl and git. If either is missing,

tell the user to install it, or to install manually from https://nextmovetheory.com.

• Non-destructive. Your own CLAUDE.md / AGENTS.md content outside the

marked rules block is preserved; unrelated skills are left alone.

• Source of truth. What gets installed is always the current main of the

public repo — the installer clones it fresh on every run, so there is no stale cache for the canon or skills.
