# test-skills-fresh.sh
#
# Generic sandbox for the `test/skills-fresh` branch — fully simulates a real
# user's `npx` install, with BOTH channels coming from the working tree:
#   • skills → installed from skills/ via `npx skills add <repo>` (exactly what
#             `npx skills add heygen-com/hyperframes` does for a real user)
#   • CLI    → wired via a `file:` dep so `npx hyperframes` resolves to the LOCAL
#             build, which carries this branch's packages/cli/src/capture changes.
# It adds NO CLAUDE.md / AGENTS.md — it mirrors the plain install, nothing more.
# You then launch your agent in the sandbox and type whatever request you want.
#
# Agents: works for Claude Code (default) and Codex. `--agent` is passed straight
# to `skills add`, so the skills land in that agent's project dir:
#   • claude-code → .claude/skills/   (launch: claude --dangerously-skip-permissions)
#   • codex       → .agents/skills/   (launch: codex --dangerously-bypass-approvals-and-sandbox)
#                   ← both launch fully auto (no approval prompts); codex stays
#                   project-local and does NOT touch your global ~/.codex/skills.
#
# Why a sandbox (and not `npx skills add heygen-com/hyperframes#test/skills-fresh`):
#   `skills add` only copies skills/. The capture tool you changed lives in
#   packages/cli (the @hyperframes/cli package), so an online skills-only install
#   would pull this branch's skills but the PUBLISHED CLI's old capture. This
#   script builds + file:-links the local CLI so capture comes from the branch too.
#
# Usage:
#   bash scripts/test-skills-fresh.sh                    # Claude Code (default)
#   bash scripts/test-skills-fresh.sh --agent codex      # Codex
#   bash scripts/test-skills-fresh.sh --rebuild          # force a CLI rebuild
#   bash scripts/test-skills-fresh.sh --no-build         # skip the build step
#   bash scripts/test-skills-fresh.sh -h                 # help
#
# What it does:
#   1. Verifies prerequisites (bun, npm, the chosen agent, optionally Chrome).
#   2. Builds the local CLI if dist/cli.js is missing OR any packages/cli source
#      is newer than the built bundle (so your capture edits are never tested stale).
#   3. Creates a fresh WORKSPACE ROOT under /tmp/skills-fresh-<timestamp>/ with a
#      package.json (`file:` CLI dep). It does NOT init a hyperframes project here
#      — the video workflows run `npx hyperframes init` inside their own subdirs.
#   4. Runs npm install so `npx hyperframes` resolves to the local CLI build.
#   5. Installs the full skills tree from the LOCAL repo via `npx skills add
#      --agent <agent>`, then prunes the internal _meta/ authoring skills so the
#      installed set matches what an end user gets.
#   6. Verifies the router + 10 workflows + 6 domain skills landed.
#   7. Prints the command to start the agent + example prompts to try.
#
# Iterate after editing:
#   • skills  → re-run this script (fresh dir), or in the existing test dir:
#                 rm -rf <skills-dir>/<name> && npx --yes skills add <repo> \
#                   --skill <name> --agent <agent> --yes
#   • capture / CLI → just re-run this script; step 2's staleness check rebuilds.
