What this skill does

# ClawSec Suite

## 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 consolidated advisory feed seed file: `advisories/feed.json`
- 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:

```bash
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)

```bash
npx clawhub@latest install clawsec-suite
```

### Option B: Manual download with signature + checksum verification

```bash
set -euo pipefail

## OpenClaw Automation (Hook + Optional Cron)

After installing the suite, enable the advisory guardian hook:

```bash
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:

```bash
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:

```bash
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`:

```bash
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`
- Feed contents: NVD CVEs, approved community advisories, and provisional GHSA-without-CVE advisories.
- Remote feed signature URL: `${CLAWSEC_FEED_URL}.sig` (override with `CLAWSEC_FEED_SIG_URL`)
- Remote checksums manifest URL: sibling `checksums.json` (override with `CLAWSEC_FEED_CHECKSUMS_URL`)
- Local seed fallback: `~/.openclaw/ski
