skilldrop 0.11.9

Released 2026-09-25 · npx skilldrop-cli@0.11.9

Every primitive now has a closed, machine-readable contract in contracts/ — skills, packs, loops, agents, and guides. validate.py checks each instance against its schema, so a typo'd manifest key fails instead of being ignored, and "tier": "claude-opus-5" is finally rejected by the lint rather than only by the style guide. Checked by a ~50-line stdlib JSON Schema subset: skilldrop still has zero runtime dependencies.
New ARCHITECTURE.md — the four primitives, why a loop is not just a long skill, why the loops are separated by reversibility, the copy-never-transform install contract and its one exception, and the five invariants worth protecting.
The README is 714 → 522 lines. Per-IDE install steps, hooks, catalogue publishing, script-shipping skills, and the authoring paths moved into guides/, split by Diátaxis kind declared in frontmatter rather than by directory. A guide that is not linked from guides/README.md fails the lint, because an unindexed guide is unfindable.
New guides for authoring: Author a new loop and Why loops, which explains why sequencing is its own primitive and why there are four lifecycle loops rather than three.
Fixed a blank line that made the reviewer-agents table render as two broken tables on GitHub.
