Nmt Update

nmt-update — update to the latest canon + skills

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 (including anything outside the markers), and does not delete unrelated skills already in .claude/skills or .agents/skills. Everything it installs is downloaded from the public GitHub repo.

Count this run — optional; policy in NextMoveTheory-README.md, section "Updates & telemetry". Skip this entirely if .nmt-config (project root) contains a line update-check: off, or the environment variable DO_NOT_TRACK or NMT_NO_UPDATE_CHECK is set. Otherwise, as your first action, tell the user in one line: "Counting this update run — only this skill's name and the installed version are sent (details: NextMoveTheory-README.md; disable: add update-check: off to .nmt-config)." Then run v="$(grep -m1 -E '^[0-9]' .nmt-version 2>/dev/null)"; curl -fsSL --max-time 2 "https://nextmovetheory.com/version?skill=nmt-update${v:+&v=$v}" >/dev/null 2>&1 || true — on any error or timeout, skip and move on; never retry, never block. This ping only counts the run; the update itself always downloads from GitHub.

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 update.
2. Read the installed and the latest version. The installed version sits in .nmt-version; the latest is the top entry of the changelog in the public GitHub repo:

   bashCopy code
   installed="$(grep -m1 -E '^[0-9]' .nmt-version 2>/dev/null)"
   latest="$(curl -fsSL --max-time 3 https://raw.githubusercontent.com/zamesin/Next-Move-Theory-Canon-and-Skills/main/CHANGELOG.md 2>/dev/null \
     | grep -m1 -E '^##[[:space:]]+[0-9]' | sed -E 's/^##[[:space:]]+([^[:space:]]+).*/\1/')"
   echo "installed=${installed:-unknown} latest=${latest:-unknown}"
   

   Report the <installed> → <latest> gap in one line. If the fetch fails or times out, say so in one line and continue to step 3 anyway — never block the update on the version check. If the two versions already match, say so and still run the install (it is idempotent, and it repairs a partial one).
3. Run the installer from that directory:

   bashCopy code
   curl -fsSL https://raw.githubusercontent.com/zamesin/Next-Move-Theory-Canon-and-Skills/main/install.sh | bash
   

   (Windows / PowerShell: irm https://raw.githubusercontent.com/zamesin/Next-Move-Theory-Canon-and-Skills/main/install.ps1 | iex.)
4. 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 update pulled in. If the changelog was fetched in step 2, add a one-line summary per version newer than the one that was installed.
5. Confirm done. Tell the user the update 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 by hand from https://github.com/zamesin/Next-Move-Theory-Canon-and-Skills (clone the repo and run bash install.sh --target <your-project-root>).
• Non-destructive. Your own CLAUDE.md / AGENTS.md content outside the <!-- Next-Move-Theory-Rules:start … end --> markers is preserved — the installer only ever rewrites what sits between the markers. Unrelated skills are left alone.
• Renamed skill. This skill used to be called nmt-upgrade. The installer removes the old nmt-upgrade folder from .claude/skills and .agents/skills and installs nmt-update in its place, so you won't end up with both.
• Source of truth. What gets installed is always the current main of the public GitHub repo — the installer clones it fresh on every run, so there is no stale cache for the canon or skills.
