After the binary swap succeeds, zot update now walks
$ZOT_HOME/extensions/ and runs git pull --ff-only on every
extension that is a git checkout.
Per-extension behaviour:
- disabled extensions: skipped
- no .git/ directory: skipped (no remote to pull from)
- dirty worktree: stashed (--include-untracked) before the pull,
popped after; conflict on pop leaves markers in place with a
warning rather than discarding the runtime state
- diverged / offline / any git failure: reported as failed and the
next extension is processed
- timeout per extension: 60s
- no build step is ever executed; authors commit the runnable
artifact, or the user rebuilds manually and /reload-ext
zot update itself never aborts because of an extension. The
binary swap is the source of truth for success.
Implementation in packages/agent/extupdate.go (~150 LoC), 13 unit
tests covering each branch including stash+pop with untracked
runtime files, diverged history, unreachable remote, and the
mixed-state scenario. README's Extensions section documents the
new behaviour.
Single Go module, four top-level packages under packages/. Import
paths become github.com/patriceckhart/zot/packages/<name>; downstream
consumers can depend on individual packages without pulling the rest.
Layout:
packages/provider/ LLM clients + catalog
packages/provider/auth/ credential store + OAuth + login server
packages/core/ agent loop, sessions, cost
packages/tui/ terminal toolkit + chat view
packages/agent/ CLI wiring, system prompt
extensions/ extproto/ modes/ tools/ skills/ swarm/
sdk/ (was pkg/zotcore, package renamed zotcore -> sdk)
ext/ (was pkg/zotext, package renamed zotext -> ext)
internal/ and pkg/ removed. The internal/assets logo moved into
packages/provider/auth/assets.
Public Go SDK identifiers renamed:
pkg/zotcore (package zotcore) -> packages/agent/sdk (package sdk)
pkg/zotext (package zotext) -> packages/agent/ext (package ext)
This breaks Go-based extensions and embedders; the JSON wire protocol
for extensions and RPC is unchanged, so non-Go extensions, already-
built extension binaries, and zot rpc consumers are unaffected.
Docs, examples, and the built-in write-zot-extension skill updated
for the new paths and identifiers. Shadow-bug fixes in code samples
(ext := ext.New -> e := ext.New).
