nanoclaw/setup/probe.sh

#!/bin/bash
# Setup step: probe — single upfront parallel-ish scan that snapshots every
# prerequisite and dependency for /new-setup's dynamic context injection.
# Rendered into the SKILL.md prompt via `!bash setup/probe.sh` so Claude sees
# the current system state before generating its first response.
#
# Pure bash by design: this runs BEFORE setup.sh has installed Node, pnpm, and
# node_modules, so it cannot rely on any Node-based tooling. Every field below
# is computed from POSIX utilities + grep/awk/curl.
#
# This is a routing aid, NOT a replacement for per-step idempotency checks.
# Each step keeps its own checks; probe tells the skill which steps to skip.
#
# Keep fast (<2s total). All probes swallow their own errors and report a
# neutral state rather than failing the whole scan.
