saperlipopette turned Git disasters into practice exercises, then passed peer review
saperlipopette creates disposable Git repositories in a temporary path, each staged into a specific broken or interesting state so users can practice recovering from it. Three releases span October 2025 to May 2026, ending with a 1.0.0 that reflects completed rOpenSci-style peer review — reviewers and editors are named in the release notes.
WorkOS is building the identity layer for agents while quietly making it easy to switch to it.
WorkOS sells enterprise-readiness infrastructure — SSO, SCIM directory sync, and AuthKit — to application developers. The recent work runs on two tracks. One is a fast-moving agent stack: agent identities registering through an open protocol, a proxy that calls third-party APIs so applications never hold user tokens, and Atlas, an AI coworker that is an end-user product rather than a developer primitive. The other is adoption and developer experience, including a local API for CI/CD testing and a reversible SCIM migration bridge.

The package grew its exercise catalogue and then stopped to be reviewed. 0.1.1 added five exercises covering git blame, finding deleted files and lines via git log, ancestry parsing with rev-parse, and worktrees, and added switch/restore instructions alongside the checkout equivalents. 1.0.0 adds no exercises at all: it is interface polish, clarified use cases, documented workflows on every manual page, and internal renaming to align scripts with the functions they contain. Internationalisation was in from 0.1.0, with Spanish and French translations of both messages and commit messages.
With review complete and the structure documented, adding exercises is the cheap next move — the 0.1.1 batch shows the pattern. Whether more translations follow depends on contributors the entries do not name.

The other is adoption and developer experience, including a local API for CI/CD testing and a reversible SCIM migration bridge.
The agent releases fit together as one bet: if agents are going to act on users' accounts, someone has to issue their identities and hold their credentials, and WorkOS is positioning to be that party in both cases. What is notable is the pairing with go-to-market plumbing. A reversible SCIM proxy with zero downtime and safe rollbacks is not a capability story, it is a switching-cost story, and shipping it alongside the agent work suggests confidence that the platform is worth migrating onto.
Expect the agent identity and token custody pieces to converge into a single documented stack, since Pipes and Agent Registration currently solve adjacent halves of the same problem. Atlas remains the thinnest-described release and the least clear in intent.
