 | Swival | `.swival/skills/`, `AGENTS.md` | `swival skills add https://github.com/DietrichGebert/ponytail` installs the six skills straight into `.swival/skills/`. Add `--global` to stage them in the library (`~/.config/swival/library`) first, then `swival skills add ponytail` (or `--global ponytail`) to activate per-project or everywhere. Also reads `AGENTS.md` from the repo root and `~/.config/swival/AGENTS.md` globally as instruction-tier fallback. |
 | VS Code + Codex extension | `AGENTS.md` | The Codex extension reads `AGENTS.md` (repo root, or `~/.codex/AGENTS.md` globally). Instruction-tier; the full Codex plugin row above adds `/ponytail` levels and hooks. |
 | Kiro | `.kiro/steering/ponytail.md` | Steering rule; copy globally or into a project. |
+| Zed | `AGENTS.md` | Auto-includes `AGENTS.md` from the worktree root as one of its default rule files for the Agent Panel. Instruction-tier. |
 | Generic agents | `AGENTS.md` or `skills/*/SKILL.md` | Copy the compact rule file or load the skill files directly. |
