# analyze-image — describe an image via Qwen3.6-Flash for text-only models.
# Usage: analyze-image <path-or-url> [focus prompt]
#   <path-or-url> is either a local file path or an http(s) URL.
# Requires: DASHSCOPE_API_KEY in env or shell rc. Returns plaintext on stdout.
#
# For inline-attached / pasted / clipboard images in Cowork or Claude Desktop,
# use dsvision-mcp instead — it auto-finds Claude Code's image-cache and
# bypasses Cowork's egress sandbox.
