+## [0.1.1] - 2026-02-13
+
+### Added
+
+- **Agent Skills Installation**: New `--ai-skills` CLI option to install Prompt.MD templates as agent skills following [agentskills.io specification](https://agentskills.io/specification)
+  - Skills are installed to agent-specific directories (e.g., `.claude/skills/`, `.gemini/skills/`, `.github/skills/`)
+  - Codex uses `.agents/skills/` following Codex agent directory conventions
+  - Default fallback directory is `.agents/skills/` for agents without a specific mapping
+  - Requires `--ai` flag to be specified
+  - Converts all 9 spec-kit command templates (specify, plan, tasks, implement, analyze, clarify, constitution, checklist, taskstoissues) to properly formatted SKILL.md files
+  - **New projects**: command files are not installed when `--ai-skills` is used (skills replace commands)
+  - **Existing repos** (`--here`): pre-existing command files are preserved — no breaking changes
+  - `pyyaml` dependency (already present) used for YAML frontmatter parsing
+- **Unit tests** for `install_ai_skills`, `_get_skills_dir`, and `--ai-skills` CLI validation (51 test cases covering all 18 supported agents)
