The `skill.json` file is the package metadata/SBOM source, and the release pipeline signs `checksums.json` with the ClawSec release key. ```bash set -euo pipefail SKILL_NAME="picoclaw-self-pen-testing" VERSION="0.0.2" REPO="prompt-security/clawsec" TAG="${SKILL_NAME}-v${VERSION}" BASE="https://github.com/${REPO}/releases/download/${TAG}" ZIP_NAME="${SKILL_NAME}-v${VERSION}.zip" TMP_DIR="$(mktemp -d)" trap 'rm -rf "$TMP_DIR"' EXIT RELEASE_PUBKEY_SHA256=[REDACTED_SECRET] curl -fsSL "$BASE/checksums.json" -o "$TMP_DIR/checksums.json" curl -fsSL "$BASE/checksums.sig" -o "$TMP_DIR/checksums.sig" curl -fsSL "$BASE/signing-public.pem" -o "$TMP_DIR/signing-public.pem" curl -fsSL "$BASE/$ZIP_NAME" -o "$TMP_DIR/$ZIP_NAME" curl -fsSL "$BASE/SKILL.md" -o "$TMP_DIR/SKILL.md" curl -fsSL "$BASE/skill.json" -o "$TMP_DIR/skill.json" ACTUAL_PUBKEY_SHA256="$(openssl pkey -pubin -in "$TMP_DIR/signing-public.pem" -outform DER | shasum -a 256 | awk '{print $1}')" if [ "$ACTUAL_PUBKEY_SHA256" != "$RELEASE_PUBKEY_SHA256" ]; then echo "ERROR: signing-public.pem fingerprint mismatch" >&2 exit 1 fi openssl base64 -d -A -in "$TMP_DIR/checksums.sig" -out "$TMP_DIR/checksums.sig.bin" openssl pkeyutl -verify -rawin -pubin \ -inkey "$TMP_DIR/signing-public.pem" \ -sigfile "$TMP_DIR/checksums.sig.bin" \ -in "$TMP_DIR/checksums.json" >/dev/null hash_file() { if command -v shasum >/dev/null 2>&1; then shasum -a 256 "$1" | awk '{print $1}' else sha256sum "$1" | awk '{print $1}' fi } verify_manifest_file() { asset="$1" path="$2" expected="$(jq -r --arg asset "$asset" '.files[$asset].sha256 // empty' "$TMP_DIR/checksums.json")" if [ -z "$expected" ]; then echo "ERROR: checksums.json missing $asset" >&2 exit 1 fi actual="$(hash_file "$path")" if [ "$actual" != "$expected" ]; then echo "ERROR: checksum mismatch for $asset" >&2 exit 1 fi } expected_archive="$(jq -r '.archive.sha256 // empty' "$TMP_DIR/checksums.json")" if [ -z "$expected_archive" ]; then echo "ERROR: checksums.json missing archive.sha256" >&2 exit 1 fi actual_archive="$(hash_file "$TMP_DIR/$ZIP_NAME")" if [ "$actual_archive" != "$expected_archive" ]; then echo "ERROR: archive checksum mismatch" >&2 exit 1 fi verify_manifest_file "SKILL.md" "$TMP_DIR/SKILL.md" verify_manifest_file "skill.json" "$TMP_DIR/skill.json" echo "Signed release manifest, archive, SKILL.md, and skill.json verified." ``` Only install or extract the archive after this verification succeeds. ## Scope This skill only performs local, read-only posture-review analysis against an existing Picoclaw posture profile. It flags: - public Web UI exposure - disabled UI auth - unrestricted workspace/tooling - unsigned verification mode - MCP trust-boundary review needs - scheduler persistence review - plaintext secret markers - multi-channel auth review ## Usage ```bash node scripts/self_pen_test.mjs --profile ~/.picoclaw/security/clawsec/current-profile.json ``` ## Validation ```bash python utils/validate_skill.py skills/picoclaw-self-pen-testing node skills/picoclaw-self-pen-testing/test/self_pen_test.test.mjs ```
