# ClawSec ClawHub Checker Adds a reputation gate on top of the `clawsec-suite` guarded installer. ## Vercel Skills Installation Install with the Vercel Skills CLI for this harness: ```bash npx skills add prompt-security/clawsec --skill clawsec-clawhub-checker -a openclaw -y ``` ## Operational Notes - Required runtime: `node`, `clawhub`, `openclaw` - Depends on: installed `clawsec-suite` - Side effects: none on other skills; this package does not rewrite installed suite files - Advisory-hook wiring is optional and manual in this release - Network behavior: reputation checks call ClawHub inspect/search endpoints - Trust model: scores are heuristic and confirmation-gated ## What It Does 1. Reads skill metadata from ClawHub (`inspect --json`) 2. Evaluates scanner status (including VirusTotal summary when present) 3. Applies additional reputation heuristics (age, updates, author history, downloads) 4. Requires explicit `--confirm-reputation` when score is below threshold ## Installation Install after `clawsec-suite`: ```bash npx clawhub@latest install clawsec-suite npx clawhub@latest install clawsec-clawhub-checker ``` Optional preflight check (validates local paths and prints recommended command): ```bash node ~/.openclaw/skills/clawsec-clawhub-checker/scripts/setup_reputation_hook.mjs ``` ## Release Artifact Verification For standalone installs, verify the signed release manifest before trusting `SKILL.md`, `skill.json`, or the archive. 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="clawsec-clawhub-checker" VERSION="0.0.8" 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="711424e4535f84093fefb024cd1ca4ec87439e53907b305b79a631d5befba9c8" 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. ## Usage Run the enhanced installer directly from this skill: ```bash node ~/.openclaw/skills/clawsec-clawhub-checker/scripts/enhanced_guarded_install.mjs \ --skill some-skill \ --version 1.0.0 ``` If a skill is below threshold, rerun only with explicit approval: ```bash node ~/.openclaw/skills/clawsec-clawhub-checker/scripts/enhanced_guarded_install.mjs \ --skill some-skill \ --version 1.0.0 \ --confirm-reputation ``` ## Optional Advisory-Hook Wiring (Manual) This release does not auto-patch `clawsec-suite` hook files. If you rely on advisory alerts that include `reputationWarning` / `reputationWarnings`, wire the checker module manually: - Source module: `~/.openclaw/skills/clawsec-clawhub-checker/hooks/clawsec-advisory-guardian/lib/reputation.mjs` - Target hook file: `~/.openclaw/skills/clawsec-suite/hooks/clawsec-advisory-guardian/handler.ts` Treat that wiring as a deliberate local customization and review it before enabling. ## Exit Codes - `0` safe to install - `42` advisory confirmation required (from clawsec-suite) - `43` reputation confirmation required - `1` error ## Configuration Environment variables: - `CLAWHUB_REPUTATION_THRESHOLD` - Minimum score (0-100, default: 70) ## Safety Notes - This is defense-in-depth, not a replacement for advisory matching - Scanner outputs can produce false positives and false negatives - Always review skill code before overriding warnings ## Development Key files: - `scripts/enhanced_guarded_install.mjs` - `scripts/check_clawhub_reputation.mjs` - `scripts/setup_reputation_hook.mjs` - `hooks/clawsec-advisory-guardian/lib/reputation.mjs` ## License GNU AGPL v3.0 or later - Part of the ClawSec security suite
