The design gate checked the 21st CLI with command -v only, so an installed-but-signed-out CLI read as READY and every 21st step failed downstream. tool_active now probes 21st whoami through a three-state function: signed in (TWENTYFIRST_TOKEN or API_KEY_21ST set, or 'Logged in as'), signed out (exact 'Not logged in'), unknown (rc != 0, timeout, unexpected output). Signed out is a new verdict, SIGN-IN REQUIRED, exit 12: design-gate.md tells the orchestrator to ask the user to run ! 21st login, end the turn, re-run the gate on their reply, and to skip 21st only on an explicit 'proceed without 21st', never silently. Unknown surfaces as exit 11 with the whoami diagnostic and a CLI-runtime remedy, so a node/PATH failure can never loop on a sign-in prompt. INCOMPLETE still wins. Hermetic suite lib/tests/design-tool-gate.test.sh (stub CLI, fixture repo through DESIGN_GATE_REPO_OVERRIDE) covers every state.

# lib/design-tool-gate.sh — Deterministic design-toolchain state check.
|
||
#
|
||
# Answers ONE question for the design gate (design-gate.md §DECISION):
|
||
# "Is the design toolchain active enough to proceed?"
|
||
#
|
||
# Source of truth = the profile system. The gate never activates a single
|
||
# tool atomically; it checks whether a profile's DESIGN-CORE tools (default
|
||
# profile: `design`) are active and, if not, points at `/profile <name>`.
|
||
#
|
||
# Two inputs from the profile, both claude-free:
|
||
# - structure: profile.sh show <profile> --plain -> "<type>\t<name>"
|
||
# - gate scope: the "# GATE-BLOCK:" line(s) in <profile>.profile — the
|
||
# allowlist of tools the gate trips on. A comment, so
|
||
# read_profile strips it and --plain never shows it. Absent
|
||
# -> fall back to every skill/plugin/mcp entry (coarse).
|
||
#
|
||
# State (active or not) is checked per channel, by type. These per-type
|
||
# checks MIRROR profile.sh:skill_status() — change one, sync the other,
|
||
# except the 21st auth state: gate-only, no skill_status counterpart.
|
||
#
|
||
# type channel class
|
||
# gstack|external|personal skill symlink in skills/ blocking
|
||
# plugin `claude plugin list` -> enabled blocking
|
||
# mcp | cli `claude mcp list` / command -v required-manual
|
||
#
|
||
# Class:
|
||
# blocking required + `/profile design` activates it directly.
|
||
# required-manual required but the profile can't flip it silently (API
|
||
# key / external install) — the gate STILL trips, names
|
||
# it, and the remedy is `/profile design` + a manual step.
|
||
# This is where the `21st` CLI lands: required, never
|
||
# silent (npm i -g @21st-dev/cli, then 21st login).
|
||
# 21st's sign-in state is three-valued: in (active),
|
||
# out (exit 12, ask to sign in), unknown (exit 11).
|
||
# Both classes trip the gate. Tools NOT on the GATE-BLOCK allowlist are
|
||
# ignored entirely (browser/plan/shotgun tooling, graphify).
|
||
#
|
||
# disabledMcpServers is NEVER read — unreliable for bi-modal servers
|
||
# (context7 can appear there yet be active via another channel).
|
||
#
|
||
# Exit: 0 = ready · 11 = ready-but-unverified (proceed, say so) ·
|
||
# 10 = incomplete (trips) · 12 = sign-in required (21st) · 2 = error.
|
||
# Usage: design-tool-gate.sh [profile] (default profile: design)
