source-command-latch-gate

source-command-latch-gate

Use this skill when the user explicitly asks to run latch gate as a manual second opinion on a request or implementation plan.

Command Template

If the user did not provide a request, ask for the request to gate. Prefer the Codex MCP latch_gate/kb_gate tool when it is available. If you use the shell fallback, explicitly substitute the user's request text; Codex does not populate Claude slash-command argument placeholders.

latch_home="${LATCH_HOME:-}"
if [ -z "$latch_home" ] && [ -n "${CLAUDE_KB_HOME:-}" ]; then
  latch_home="$CLAUDE_KB_HOME"
fi
if [ -z "$latch_home" ]; then
  search_dir="$PWD"
  while [ "$search_dir" != "/" ]; do
    if [ -f "$search_dir/AGENTS.md" ]; then
      latch_home="$(sed -n 's|.*Follow `\([^`]*\)/README\.md` per-user setup.*|\1|p' "$search_dir/AGENTS.md" | head -n 1)"
      [ -n "$latch_home" ] && break
    fi
    search_dir="$(dirname "$search_dir")"
  done
fi
if [ -z "$latch_home" ]; then
  candidate="$(git rev-parse --show-toplevel 2>/dev/null || pwd)"
  if [ -f "$candidate/src/mcp_server.py" ] && [ -d "$candidate/commands" ]; then
    latch_home="$candidate"
  fi
fi
if [ -z "$latch_home" ] || [ ! -f "$latch_home/src/mcp_server.py" ]; then
  echo "Could not find latch checkout; set LATCH_HOME to your latch install." >&2
  exit 1
fi
request="$(cat <<'EOF'
<exact user-provided request to gate>
EOF
)"
if [ -z "${LATCH_GATE_BACKEND:-}" ] && [ -z "${CLAUDE_KB_GATE_BACKEND:-}" ] && [ -z "${LATCH_MODEL_BACKEND:-}" ]; then
  export LATCH_GATE_BACKEND=codex
fi
bash "$latch_home/bin/run_latch_gate.sh" "$request"

After the command returns, show an explicit Latch gate block. Prefer the returned findings object when present. If the result says latch is UNLATCHED, report that latch gate was skipped, do not claim KB evidence was read, and tell the user to run /unlatch to re-latch. Otherwise, lead with provenance, then include the recommendation, summary/rationale, receipt or source basis, cited evidence nodes with status/current authority, any better next action, and uncovered claims.
