0.1.0 - 2026-06-12

Added

• Initial release of skillscore.
• 24 scoring rules across 7 rubric categories (A frontmatter, B description, C conciseness, D structure, E instruction quality, F hygiene, G safety penalty), each citing its source authoring guide (Anthropic, Antigravity, Codex, Flutter).
• Target profiles: --target claude | antigravity | codex | universal implemented as data (per-target rule activation + severity overrides).
• Name-agnostic, case-insensitive skill discovery for single manifests, skill folders, and whole directory trees; BOM/CRLF tolerance; graceful handling of malformed frontmatter, binary files, and symlinks.
• Reporters: pretty (colored, per-category bars), json (stable CI shape), and sarif (valid SARIF 2.1.0).
• CI gating via --min-score and --strict; exit codes 0/1/2.
• skillscore rules and skillscore explain <rule-id> with rationale, fix, and source citations.
