# OpenClaw Traffic Guardian

This is a baseline specification skill. It intentionally does not ship a proxy or runtime implementation yet.

## Vercel Skills Installation

Install with the Vercel Skills CLI for this harness:

```bash
npx skills add prompt-security/clawsec --skill openclaw-traffic-guardian -a openclaw -y
```

## 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

Only install or extract the archive after this verification succeeds.

## Scope

Builders should use this skill as the OpenClaw landing zone for runtime traffic monitoring:

- operator-scoped HTTP proxy inspection
- optional HTTPS inspection with per-process CA trust
- outbound exfiltration detection
- inbound injection detection
- approval-sensitive social-account mutation review
- redacted local threat logs
- optional OpenClaw hook/status integration

Do not merge this capability into `clawsec-scanner`, `openclaw-audit-watchdog`, or `soul-guardian`. Those skills have different trust boundaries and safety contracts.

## Safety Contract

- Opt-in only.
- Detect-and-log by default.
- No automatic system CA installation.
- No global `HTTP_PROXY` or `HTTPS_PROXY` changes.
- No blocking in the first implementation.
- Redact secrets before logs or conversation alerts.
- Keep all state under `OPENCLAW_TRAFFIC_GUARDIAN_HOME` or `~/.openclaw/security/clawsec/traffic-guardian`.

## Builder Entry Points

Read `SPEC.md` before implementing. Use the placeholder folders as follows:

From prompt-security/clawsec, AGPL-3.0.
