If your day involves switching between AI chat, notes, documents and planning, pewdiepie-archdaemon/odysseus is the obvious first click. It is a self-hosted workspace that puts all of those in one application, which matters if you keep losing context every time you copy a model answer into a separate note app. A sensible first experiment: move one real recurring task, like a weekly research summary, into it for a few days and see whether having the chat, sources and plan side by side actually saves you the usual round trips. Check feature maturity against the specific jobs you need, since a combined tool is only a win if each piece is good enough for your case.
For coding work, the choice is between structure and review. obra/superpowers is a skill collection that walks an assistant through requirements, planning, implementation, tests and review, which helps on longer features where you want a checkpoint before a big pile of edits lands. alibaba/open-code-review does something different: it has an AI review your diff and places comments on the relevant lines, with file selection and positioning handled by ordinary program logic. If your agent tends to sprint ahead, start with superpowers and adapt its checkpoints; if your problem is verifying a large diff quickly, run open-code-review on one recent pull request and see whether its line-anchored comments are easier to check than a wall of prose.
