Clawsec Suite

ClawSec Suite

Vercel Skills Installation

Install with the Vercel Skills CLI for this harness:

npx skills add prompt-security/clawsec --skill clawsec-suite -a openclaw -y

Operational Notes

• Required runtime: node, npx, openclaw, curl, jq, shasum, openssl, unzip
• Side effects: setup scripts install an advisory hook under ~/.openclaw/hooks, optionally create an unattended openclaw cron job, and use npx clawhub@latest install for guarded installs
• Network behavior: fetches signed advisory feed artifacts and remote catalog metadata unless you pin local paths
• Trust model: the suite can recommend removal or block risky installs, but removal/install overrides stay approval-gated

This means clawsec-suite can:

• monitor the ClawSec advisory feed,
• track which advisories are new since last check,
• cross-reference advisories against locally installed skills,
• recommend removal for malicious-skill advisories and require explicit user approval first,
• and still act as the setup/management entrypoint for other ClawSec protections.

Included vs Optional Protections

Built into clawsec-suite

• Embedded signed advisory trust set: advisories/feed.json, feed.json.sig, checksums.json, checksums.json.sig, and feed-signing-public.pem
• Portable heartbeat workflow in HEARTBEAT.md
• Advisory polling + state tracking + affected-skill checks
• OpenClaw advisory guardian hook package: hooks/clawsec-advisory-guardian/
• Setup scripts for hook and optional cron scheduling: scripts/
• Guarded installer: scripts/guarded_skill_install.mjs
• Dynamic catalog discovery for installable skills: scripts/discover_skill_catalog.mjs

Installed separately (dynamic catalog)

clawsec-suite does not hard-code add-on skill names in this document.

Discover the current catalog from the authoritative index (https://clawsec.prompt.security/skills/index.json) at runtime:

SUITE_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-suite"
node "$SUITE_DIR/scripts/discover_skill_catalog.mjs"

Fallback behavior:

• If the remote catalog index is reachable and valid, the suite uses it.
• If the remote index is unavailable or malformed, the script falls back to suite-local catalog metadata in skill.json.

Installation

Cross-shell path note

• In bash/zsh, keep path variables expandable (for example, INSTALL_ROOT="$HOME/.openclaw/skills").
• Do not single-quote home-variable paths (avoid '$HOME/.openclaw/skills').
• In PowerShell, set an explicit path:
• $env:INSTALL_ROOT = Join-Path $HOME ".openclaw\\skills"
• If a path is passed with unresolved tokens (like \$HOME/...), suite scripts now fail fast with a clear error.

Option A: Via clawhub (recommended)

npx clawhub@latest install clawsec-suite

Option B: Manual download with signature + checksum verification

OpenClaw Automation (Hook + Optional Cron)

After installing the suite, enable the advisory guardian hook:

SUITE_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-suite"
node "$SUITE_DIR/scripts/setup_advisory_hook.mjs"

The setup script prints a preflight review before it installs and enables the persistent hook.

Optional: create/update a periodic cron nudge (default every 6h) that triggers a main-session advisory scan:

SUITE_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-suite"
node "$SUITE_DIR/scripts/setup_advisory_cron.mjs"

The cron setup script prints a preflight review before it creates or updates the unattended job.

What this adds:

• scan on agent:bootstrap and /new (command:new),
• compare advisory affected entries against installed skills,
• consider advisories with application: "openclaw" (and legacy entries without application for backward compatibility),
• notify when new matches appear,
• and ask for explicit user approval before any removal flow.

Restart the OpenClaw gateway after enabling the hook. Then run /new once to force an immediate scan in the next session context.

Guarded Skill Install Flow (Double Confirmation)

When the user asks to install a skill, treat that as the first request and run a guarded install check:

SUITE_DIR="${INSTALL_ROOT:-$HOME/.openclaw/skills}/clawsec-suite"
node "$SUITE_DIR/scripts/guarded_skill_install.mjs" --skill helper-plus --version 1.0.1

Behavior:

• If no advisory match is found, install proceeds.
• If --version is omitted, matching is conservative: any advisory that references the skill name is treated as a match.
• If advisory match is found, the script prints advisory context and exits with code 42.
• Then require an explicit second confirmation from the user and rerun with --confirm-advisory:

node "$SUITE_DIR/scripts/guarded_skill_install.mjs" --skill helper-plus --version 1.0.1 --confirm-advisory

This enforces:

1. First confirmation: user asked to install.
2. Second confirmation: user explicitly approves install after seeing advisory details.

Embedded Advisory Feed Behavior

The embedded feed logic uses these defaults:

• Remote consolidated feed URL: https://clawsec.prompt.security/advisories/feed.json
