# downloaded directly, checked against the SHA-256 gradle.org publishes,

# REA, "Reverse Engineer Anything" (https://github.com/morluto/rea), from the
# rea-agents npm package. The tarball is checked against the integrity hash
# the npm registry lists for it; its dependencies are locked by the
# npm-shrinkwrap.json it ships. npm blocks dependency install scripts by
# default, so frida (optional, runtime instrumentation) stays unbuilt.
# REA runs in its own container (see run.sh), not next to Claude Desktop,
# because some of its tools run the target. It finds Ghidra through
# GHIDRA_INSTALL_DIR and needs procps' ps (installed above).
