# Changes

## [0.2.3] — 2026-02-20

### Added

- `score` command: rate skills 0–100 against a best-practices checklist
  (structural 60pts + quality 40pts)
- `test` command: simulate skill activation with query matching
- `upgrade` command: detect and apply missing best-practice fields
  (`compatibility`, `metadata.version`, `metadata.author`, trigger phrases)
- `doc` command: generate skill catalogs with diff-aware output
- `init` command: scaffold new skill directories from templates
- `lint` subcommand and `--lint` flag for semantic quality checks (I001–I005)
- `--structure` flag for directory structure validation (S001–S004)
- Cross-skill conflict detection (name, description, tool overlap)
- Watch mode (`--features watch`) for live re-validation on file changes
- JSON output format (`--format json`) for CI integration
- Claude Code plugin skill: `aigent-scorer`
- Comprehensive README with command examples and scoring documentation

### Changed

- Multi-skill prompt generation with `to-prompt` accepting multiple directories
- Builder supports building from existing SKILL.md files

### Fixed

- Jaccard similarity now case-insensitive (matching doc comment contract)
- `doc` catalog resolves `entry.location` to parent directory correctly
- `upgrade --apply` handles partial metadata blocks (inserts missing keys
  under existing `metadata:` rather than skipping)
- Windows CI: platform-specific script permission checks (`#[cfg(unix)]`)

## [0.1.0] — 2026-02-20

### Added

- Core library: error types (`AigentError`), data model (`SkillProperties`),
  YAML frontmatter parser, skill directory validator, XML prompt generator,
  and skill builder
- CLI tool with subcommands: `validate`, `read-properties`, `to-prompt`,
  `build`, `init`
- Full compliance with the
  [Anthropic agent skill specification](https://platform.claude.com/docs/en/agents-and-tools/agent-skills/best-practices):
  name/description validation, XML tag rejection, reserved word checks,
  Unicode NFKC normalization, body-length warnings
- Dual-mode skill builder: deterministic (zero-config) and LLM-enhanced
  (Anthropic, OpenAI, Google, Ollama) with per-function graceful fallback
- Claude Code plugin with two skills (`aigent-builder`, `aigent-validator`)
  operating in hybrid CLI/prompt-only mode
- Install script (`install.sh`) for non-Rust users
- `--about` flag displaying project info from compile-time metadata
- Cross-platform support: Linux (x86_64, aarch64), macOS (x86_64, aarch64),
  Windows (x86_64)
- CI pipeline: formatting, linting, testing, release builds on all platforms
- Release workflow: automated GitHub Releases and crates.io publishing on tag push
