# Install Anthropic-style skills (each a directory with SKILL.md, optionally a
# references/ subfolder) into EVERY agent's workspace on a board.
#
# Why per-agent workspace and not a shared bundle: ZeroClaw's `read_skill`
# returns only SKILL.md; a skill's `references/*.md` are read via the general
# `file_read` tool, which is workspace-sandboxed. So references are only
# reachable when the skill lives under an agent's own workspace
# (`~/.zeroclaw/agents/<alias>/workspace/skills/<name>/`). A shared/skills bundle
# surfaces the skill but its references get blocked by the file_read sandbox.
#
# The skill NAME is the directory name (not the frontmatter `name`).
#
#   ./push-skill.sh <adb-serial> [path]
#     path with a SKILL.md            → install that one skill
#     path that CONTAINS skill dirs   → install every skill under it
#     (default: this script's skills/ directory — all bundled skills)
