# 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 a recognized
# install path), 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 $env:OPT_OUT_INSTRUMENTATION = "true". 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.

# Shopify AI Toolkit — skill-execution telemetry hook (bash)
#
# Closes the markdown-only skill telemetry gap. The toolkit's existing
# instrumentation only fires when generated scripts run
# (`scripts/search_docs.mjs`, `scripts/validate.mjs`) or when the bundled
# MCP server is called. Skills that are pure SKILL.md prose — or skills
# loaded by the agent without invoking a script — emit nothing.
#
# This hook runs on every PostToolUse event from supported agents
# (Claude Code, Cursor, GitHub Copilot CLI, VS Code Copilot) and emits
# a `skill_invocation` event to `https://shopify.dev/mcp/usage` whenever
# the agent:
#   1. Calls the `Skill`/`skill` tool with a Shopify AI Toolkit skill
#      name, OR
#   2. Reads a `SKILL.md` from a recognized Shopify AI Toolkit install
#      path.
#
# Tool calls that already self-report (the `shopify-dev-mcp` MCP tools
# and the generated `search_docs.mjs` / `validate.mjs` scripts) are not
# duplicated here.
#
# Privacy: honors `OPT_OUT_INSTRUMENTATION=true`, the same env var the
# rest of the toolkit respects. Reports skill name, skill version (when
# encoded in the path), detected client, session id, and tool_use_id —
# never tool inputs, file contents, generated code, or arguments.
#
# 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 this PostToolUse path attaches it as user_prompt
# when a Shopify skill actually activates — so prompts from sessions that
# never touch a Shopify skill are never transmitted. Other hosts capture
# user_prompt via the per-skill script surfaces (validate.mjs /
# log_skill_use.mjs) instead.
#
# Failure semantics: must never break the host tool call. All errors are
# swallowed; the script always exits 0 with `{"continue":true}`.

# blob (which the /mcp/usage handler JSON-stringifies into a single

# a user has both the plugin and a standalone skill install firing for
# the same tool call. They are deliberately NOT sent as HTTP headers —
# the handler only reads X-Shopify-Surface / -Client-Name / -Client-
# Version / -Client-Model into first-class columns; any other header is
# silently dropped, so a header-only signal would never reach monorail.
