# install-skill.sh — stamp the peltier Agent Skill into a consumer repo.

#   sh scripts/install-skill.sh <target-repo> [--layout claude|agents|both]
#   sh scripts/install-skill.sh --zeroclaw-variant <out-dir>
#
# The skill is one directory (SKILL.md + references/ + scripts/ + assets/),
# already in the Agent Skills format (agentskills.io) that Claude Code, Codex,
# Copilot, VS Code, Cursor, Gemini CLI, opencode, Goose, Amp, Zed and others
# load natively. All this script does is copy that one canonical directory to
# the discovery path(s) a harness actually reads:
#
#   .claude/skills/peltier/   Claude Code (also read by Copilot, VS Code,
#                             opencode, Amp, and Cursor in compat mode)
#   .agents/skills/peltier/   the cross-tool convergence path (Codex, Zed,
#                             Cursor, Copilot, VS Code, Gemini CLI, opencode,
#                             Goose, Amp)
#
# --layout both (the default) writes both. That is two copies in YOUR repo;
# keep them identical (re-run this script to update both; peltier's own CI
# shows the diff -r pattern for enforcing it).
#
# --zeroclaw-variant writes a copy WITHOUT scripts/ to <out-dir>: ZeroClaw's
# skill security policy blocks script files by default (skills.allow_scripts
# is off), so its variant runs preflight from the peltier checkout instead —
# the skill's SKILL.md already explains that path. Then install it with:
#   zeroclaw skills install <out-dir>
#
# The skill still needs a peltier checkout at runtime (bench-runner lives
# there). Set PELTIER_HOME in the environment your agent runs in.
