Reverts the LOW-severity dead-import removal (require('fs')/require('path'))
that changed the file hash and broke 9 golden-install-parity fixtures. The
golden test computes per-runtime hashes of installed hook files; regenerating
all 9 fixtures for a cosmetic cleanup is disproportionate. Dead imports are
harmless (Node caches built-in requires) — noted as a follow-up nit.

// gsd-hook-version: {{GSD_VERSION}}

|
// gsd-cursor-pre-tool.js — Cursor preToolUse hook (ADR-1239 / #2089)
|
|
//
|
|
// Cursor invokes this script before each tool call executes.
|
|
// Protocol: JSON from Cursor on stdin; JSON response on stdout.
|
|
//
|
|
// Input schema (cursor preToolUse):
|
|
// { tool_name, tool_input, conversation_id, generation_id, model,
|
|
// hook_event_name, cursor_version, workspace_roots, user_email,
|
|
// transcript_path }
|
|
//
|
|
// Output schema (cursor preToolUse):
|
|
// { additional_context?: string, block?: boolean, reason?: string }
|
|
//
|
|
// Behaviour:
|
|
// - If a write-class tool targets .planning/, reminds the agent to keep
|
|
// STATE.md current before the write proceeds.
|
|
// - Fails open: any error silently exits 0 so a hook bug never wedges Cursor.
|
|
//
