Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Marketplace registry writes take a lock and re-read before saving

Plugins

Two sessions editing plugin marketplaces at once no longer clobber each other's entries.

What

Changes to the list of installed plugin marketplaces (refresh times, installs, auto-update toggles) now take a lock file first and re-read the current file inside it, so two Claude Code sessions running at once no longer overwrite each other's entries.

Details
  • The helper acquires a .lock alongside known_marketplaces.json with retries, applies the mutation to freshly read state, and skips the write entirely when nothing changed.
  • If the lock cannot be taken or is compromised, it logs known_marketplaces.json lock compromised:, writes anyway, and reports tengu_known_marketplaces_fallback_write.
  • Marketplaces whose install location sits inside a bundled plugin directory return no write at all, so those entries are never rewritten.
Evidence

tengu_known_marketplaces_fallback_write, known_marketplaces.json lock compromised:

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
