switch-extension-source

Toggle a monorepo extension between npm (published) and local (working tree) source.

Why this exists

GUI equivalent: Settings → Packages exposes a per-row Reset to published version action (change: reset-override-to-npm) that resets a local/git-installed row back to its canonical npm:<name> — install-first / remove-second, confirm-gated. It is the one-click UI analog of switch <pkg> npm here; keep the two semantically aligned (both drop the local packages[] registration only, never the working-tree files).

On a dev machine you want extensions to load your live working tree so edits take effect. Distribution users consume the published npm package. Both can be wired at once across two config layers, and whichever pi resolves last wins — non-deterministic ("I edited it but nothing changed"). This skill enforces exactly one source per package.

  GLOBAL ~/.pi/agent/settings.json   "packages": [...]
    npm   -> "npm:<npmName>"
    local -> "<repoRoot>/packages/<dir>"      (dir path; pi resolves package.json "pi")

  PROJECT <repo>/.pi/settings.json   "packages":[{ source, extensions:["+packages/<dir>/<entry>"] }]
    local overlay -> only with --overlay; loads ONLY inside this repo; needs pi.extensions

local (default) = global dir path → loads in every session everywhere. local --overlay = project overlay → loads only when running pi inside this repo.

Commands

npx tsx ./scripts/switch-source.ts status               # where each installed pkg loads from
npx tsx ./scripts/switch-source.ts local <pkg>          # -> local working tree (global path)
npx tsx ./scripts/switch-source.ts local <pkg> --overlay# -> local, this-repo-only (extensions only)
npx tsx ./scripts/switch-source.ts npm   <pkg>          # -> published npm build

<pkg> = monorepo dir name (kb-extension) OR npm name (@blackbelt-technology/pi-dashboard-kb-extension).

Each switch removes all other representations of that package, timestamped-backs-up every file it edits (*.bak-switch-*), and re-validates JSON before writing.

Procedure

1. status — see current source per package.
2. local <pkg> or npm <pkg> — flip it. Script guarantees single-source.
3. Re-load: packages[] is read at session init, so the change takes effect on the next session start. Respawn sessions or npm run reload (reload alone may not re-resolve the package list in an already-running process — fresh session is the guaranteed path).

Pitfalls

• Bridge plugins (flows/goal/automation) are dashboard-managed via dashboardPluginBridges / _dashboardManagedPackages. This skill does NOT toggle those — leave them to the dashboard UI.
• npm copy is a frozen snapshot, not a symlink to your monorepo. After npm mode your working-tree edits do NOT load until you local again.
• --overlay needs pi.extensions — skill-only packages (pi.skills, no extensions) can't use the overlay form; use plain local (global dir path).
• Same package wired in both layers = non-deterministic load order. Always end with status showing one source.

Verification

• npx tsx ./scripts/switch-source.ts status shows the target package at exactly one source.
• python3 -c "import json; json.load(open('<file>'))" confirms both settings files are valid JSON.
• Respawn a session; the extension loads from the chosen source.
