CARGO-NIX RESOLVER EXPOSES TEST TARGETS, PLUGIN ECOSYSTEM EXPANDS

The cargo-nix plugin now surfaces integration-test targets for workspace members, eliminating the sandbox workaround nextest needed to discover builds.

The cargo-nix resolver gained API_LEVEL 3 support for reporting integration-test targets across workspace members, matching how cargo autodiscovers `tests/*.rs`, `tests/<dir>/main.rs`, and `[[test]]` overrides [1]. This unblocks nextest's reuse-build optimization path and cuts the friction for consumers who previously had to run `cargo metadata` in isolation just to learn target names. Meanwhile, the plugin ecosystem is consolidating: Claude's community plugin registry is absorbing batches of validated integrations, with 5 plugins added across the rudder suite [2] and content-intelligence plus five others re-batched after review [3]. Official plugins expanded to include Shippo, PayPal, and mattpocock-skills [4] [5] [6]. Knowledge-work-plugins is cycling through automated SHA bumps across Carta, Wix, and Langfuse with pre-validated binaries [7] [8] [9], keeping the dependency graph tight. Across all four desks: 9 commits, 73 PRs merged in the last 24 hours.

Action items

→ Review and merge the cargo-nix test-targets PR if you depend on nextest reuse-build anthropics/cargo-nix-plugin [plan]
→ Monitor knowledge-work-plugins SHA bump PRs and approve scans before merging anthropics/knowledge-work-plugins [monitor]
→ Add any required plugins from the official registry batches to your configuration anthropics/claude-plugins-official [plan]
