# Self-test for the typescript-ops skill.
#
# Offline-deterministic (no network, no TypeScript compiler required). Asserts
# structural integrity (frontmatter, references present + linked) and — the
# load-bearing check — the staleness verifier contract (SKILL-RESOURCE-PROTOCOL
# §7, §10): the catalogued version-bearing facts (TypeScript major, zod,
# valibot) stay named in the prose and the dated currency note stays present.
# Resolves paths relative to itself so it works in the repo and once installed
# to ~/.claude/skills/typescript-ops/.
#
# Usage:   bash tests/run.sh
# Exit:    0 all pass, 1 one or more failures
