#!/usr/bin/env bash
#
# Install coding-spec as an agent skill so it can be triggered with /coding-spec.
#
# Usage:
#   ./install.sh [claude|antigravity|codex|all] [--dir TARGET_PROJECT]
#
# Run it from inside a clone of the repo, or pipe it straight from GitHub:
#   curl -fsSL https://raw.githubusercontent.com/notEhEnG/coding-spec/main/install.sh | bash -s -- claude
#
# It copies the whole repository (SKILL.md + toolkit CLI + auditor) into the
# tool's skill directory under the target project, so /coding-spec can drive
# both the toolkit and the auditor.

Done. Trigger it with:
  /coding-spec init
  /coding-spec spec "Your Feature"
  /coding-spec audit docs/specs/your-feature.md

Or just ask your agent: "install this skill https://github.com/notEhEnG/coding-spec"
