Index of the amarbaro Mojo libraries. Each one is its own repository with tests against an oracle,
a CI badge, docs/api.md, docs/design.md and an agent skill in skills/.
Every library is a conda package on prefix.dev/amarbaro/amarbaro, named mojo-<name>; the import name is in each README.

Toolchains: Mojo 1.2 stable; the weekly matrix also builds every library on the current nightly, and reports the ones whose scripts/ci.sh cannot select one (xmojo pins 1.2.0).

Tools (command-line programs, not libraries): mojo-ablate, behavior steering for local models in Mojo: directions, rank-1 edit, TPE, BF16 bake.
The table is generated from each library's pyproject.toml by tools/gen.mojo; scripts/check.sh
fails when it is stale, and scripts/check.sh --write refreshes it. Toolchain is the pin the
library builds with; "our deps" are other libraries from this table.
Every library follows one checklist from plan to publish: file layout, memory-capped builds,
docs and skill, stable and nightly Mojo, review. Its mechanical half is mojo-lib-audit.
