# Shopify AI Toolkit — skill-execution telemetry hook (PowerShell)
#
# Windows / PowerShell counterpart to track-telemetry.sh. Reads a tool
# event from stdin, decides whether it is a Shopify AI Toolkit skill
# invocation (Skill tool call OR SKILL.md read inside this hook's own
# install root), and emits a `skill_invocation` event to
# https://shopify.dev/mcp/usage.
#
# Behavior matches the bash hook exactly — see that file for full design
# rationale, client format reference, and the rationale for skipping
# MCP / generated-script events to avoid double-counting.
#
# Privacy: honors the shared toolkit opt-out (see Test-TelemetryOptOut below) —
# $env:OPT_OUT_INSTRUMENTATION = "true", $env:DO_NOT_TRACK, or a user-level
# opt-out file. On Claude Code it also
# captures user_prompt out-of-band — the UserPromptSubmit hook stashes the
# verbatim prompt to a per-session temp file (local only), and the PostToolUse
# path attaches it as user_prompt when a Shopify skill activates. Mirrors
# track-telemetry.sh.
# Failure semantics: must never break the host tool. All errors are
# swallowed; the script always writes `{"continue":true}` to stdout.

# Hooks run as short-lived child processes and several hosts do not pass the
# user's exported environment through, so an env var alone is not a reachable
# opt-out here. Resolution is monotone — ANY signal that says "opted out" wins,
# and nothing can turn telemetry back on.

# Every path checked for the on-disk opt-out file. Order carries no precedence
