/**
 * Cross-skill dependency detection
 *
 * SKILL_CROSS_SKILL_AUTH_UNDECLARED — fires when SKILL.md body prose declares
 * a dependency on a sibling skill (backtick-wrapped `plugin:skill`) or on an
 * `ANTHROPIC_*_API_KEY` / `ANTHROPIC_*_KEY` environment variable but the
 * frontmatter `description` field does not name that dependency.
 *
 * Agents that load a skill by description alone must be able to see its
 * auth/pre-flight requirements without reading the body. When the dependency
 * is silent in the description, a sibling skill can be loaded in isolation
 * and fail mysteriously at runtime.
 *
 * The detector is narrow on purpose: false positives cost author attention,
 * so we only match the two explicit patterns where the author has already
 * stated the dependency in the body.
