From 3bae87901127f21fe0a3391b950ab402ab631bc5 Mon Sep 17 00:00:00 2001 From: Jianyu Lin Date: Fri, 3 Apr 2026 12:18:45 +0800 Subject: [PATCH 1/2] fix: auto-configure sub-agent permissions for parallel research Claude Code sub-agents don't inherit session-level permissions from settings.local.json (anthropics/claude-code#18950), causing parallel research tasks to fail when sub-agents try to use Bash (CDP curl), WebSearch, or WebFetch. This adds an `ensurePermissions()` step to `check-deps.mjs` that automatically writes the required permissions to `~/.claude/settings.json` (global scope, inherited by all agents including sub-agents). The function is idempotent, non-blocking on failure, and handles fresh installs.

PreToolUse hooks are the only permission mechanism that works for sub-agents (highest priority in the permission evaluation flow). This commit: - Adds approve-tools-hook.mjs: auto-approves CDP curl (localhost only), skill scripts, WebSearch, and Jina WebFetch - Replaces ensurePermissions() with ensureHooks() in check-deps.mjs: installs the hook to ~/.claude/hooks/ and registers it in settings.json - Hook is idempotent, non-blocking on failure, auto-refreshes on update Tested with 45 E2E tests covering: all CDP endpoints, dangerous command rejection, WebSearch/WebFetch conditional approval, edge cases, idempotency, existing config preservation, and auto-refresh.
