# Install kilroy skills and binary symlinks for local agent discovery.
#
# Idempotent: safe to re-run after every `go build`. All links point back to
# this checkout so edits flow directly from the repo to installed locations.
#
# What this installs:
#
#   Binary:
#     ~/.local/bin/kilroy                         -> <repo>/kilroy
#
#   Workflow package root (stable path for --package):
#     ~/.local/share/kilroy/workflows             -> <repo>/workflows
#
#   Claude Code skills:
#     ~/.claude/skills/using-kilroy               -> <repo>/skills/using-kilroy
#
#   Codex skills (codex discovers from ~/.agents/skills/, not ~/.codex/skills/):
#     ~/.agents/skills/using-kilroy               -> <repo>/skills/using-kilroy
#
#   Opencode skills (user-level opencode config dir):
#     ~/.config/opencode/skills/using-kilroy      -> <repo>/skills/using-kilroy
#
# The `quick-launch` and `pr-review` skills (and their workflow packages) now
# live in the gf-software-factory repo at sibling location
# `gf-software-factory/skills/{quick-launch,pr-review}` and
# `gf-software-factory/workflows/{quick-launch,pr-review}`. Install those via
# `gf-software-factory/scripts/install-kilroy-host.sh`.
