design-tool-gate.sh: deterministic design-toolchain state check. Reads the
design-core tools from design.profile's `# GATE-BLOCK:` allowlist + their
types via `profile.sh show design --plain` (claude-free parse contract),
checks each on its own channel (skill symlink / claude plugin list / claude
mcp list / command -v). Never reads disabledMcpServers. Exit 0 ready · 10
incomplete · 2 error.
Remedy is always a profile (/profile design), never an atomic tool toggle —
the profile system stays the single source of truth for activation. magic is
required-but-manual: it TRIPS the gate (not advisory) and the output names
the MAGIC_API_KEY step. Non-design tools bundled in the profile (browse,
plan-*, design-shotgun, graphify) are excluded from the trip via GATE-BLOCK,
so the gate fires only on real design tools.
design-gate.md: §DECISION rewritten profile-based (tier → run script → branch
on 3 groups), replacing the old atomic "ask user to activate ui-ux-pro-max".
§DETECTION unchanged. design.profile: add the `# GATE-BLOCK:` allowlist
(8 design-core tools); it is a comment, so read_profile/--plain are unaffected.
Verified: shellcheck clean; magic-off (real design profile) → exit 10 +
API-key line; all active → exit 0; browse-off (non-GATE-BLOCK) → exit 0,
no trip.
