#!/usr/bin/env bash
# Install the DeepSeek Harness side of claude-harness.
#
# This script never installs the Cordis bundle into a profile: the Desktop
# profile is Electron-managed, so the bundle goes through the GUI Plugins page
# or the model-facing `plugin_manager` tool. The script prepares the global
# instructions, the user skill root, and the role files, then prints the bundle
# path.
#
# Usage:
#   bash dsh/install.sh --check
#   bash dsh/install.sh --global
#   bash dsh/install.sh --skills [--superpowers-from <dir>]
#   bash dsh/install.sh --roles
#   bash dsh/install.sh --all
#   bash dsh/install.sh --openspec
#
# Run it from a terminal, not from inside a DSH session: --global, --skills and
# --roles write outside the session workspace and would require approval.

Usage: bash dsh/install.sh [--check] [--global] [--skills] [--roles] [--all] [--openspec]
       bash dsh/install.sh --skills --superpowers-from <dir>

  --check                 verify python3, git, node, hooks, bundle, skills, and roles (offline)
  --global                back up and write \$DSH_HOME/AGENTS.md from global/CLAUDE.md
  --skills                sync + verify + copy superpowers and local dsh/skills into \$DSH_HOME/skills
  --roles                 copy roles/ into \$DSH_HOME/roles
  --all                   --check + --global + --skills + --roles, then print the bundle step
  --openspec              add the agents skill adapter to the current OpenSpec project
  --superpowers-from DIR  sync superpowers skills from DIR (the repo root or its skills/)

Superpowers source, first match wins:
  1. --superpowers-from DIR
  2. \$DSH_SUPERPOWERS_SOURCE
  3. the pinned clone \$DSH_HOME/superpowers at \$DSH_SUPERPOWERS_REF
     (default v7.0.1), cloned or updated from \$DSH_SUPERPOWERS_REPO
     (default https://github.com/obra/superpowers); offline it is reused
     only when already on the ref
  4. legacy: the Claude Code plugin cache, then ~/.claude/skills
     (raw copy, warns; removal is #66)

Explicit sources are synced in place (no network, no pin enforcement); the
synced tree is verified before anything is copied. Get the default source
once: $CLONE_HINT

Bundle installation itself is done in DSH:
  Plugins -> install a bundle from $BUNDLE
or ask the agent to call plugin_manager install_bundle with that target.

Install it in the current DSH profile (the Desktop profile is Electron-managed):

  - or ask the agent to call plugin_manager install_bundle with target "$BUNDLE".
Do not edit \$DSH_HOME/profiles/desktop/package.json or cordis.patch.yml by hand.

Optional: add CodeGraph as an MCP server from dsh/mcp.codegraph.yml.
