# install-paliadin-skill — copy the Paliadin skill into the local Claude
# Code config so the long-lived `claude` pane on this host picks it up.
#
# Run on every host that hosts a Paliadin tmux session — that means:
#   - mRiver (m's laptop, the prod target reached via SSH from paliad.de)
#   - any laptop running paliad's LocalPaliadinService directly
#
# The skill at ~/.claude/skills/paliadin/SKILL.md is what teaches Claude
# to react to `[PALIADIN:<uuid>]` envelopes by writing the response to
# /tmp/paliadin/<uuid>.txt. It survives /clear and fresh sessions because
# Claude's skill router auto-matches by description, not by an in-memory
# system prompt.
#
# Idempotent — re-running after a repo update is the supported way to
# refresh the skill on a host.
