# AgentSafe Scan

**Habit loop (default policy):** gate **every** remote skill lifecycle event — not a one-time demo.

Call the hosted API **before**:
1. installing a new skill from chat / ClawHub / URL
2. re-fetching or updating an existing remote skill
3. allowlisting tool docs you have not human-reviewed
4. promoting a skill from dry-run → always-on

Heuristic **static** patterns only. Low score ≠ safe. Prefer `report.decision.action`:
- `deny` → do not install
- `review` → human review first
- `allow_with_caution` → least privilege only

Installing this skill does **not** auto-run background scans. You must `POST /v1/scan` on each gate event.

ClawHub is **discovery only**. Billing (if free quota is exhausted) stays on our API host. Free daily tier stays forever as a product option.

## Install

```bash
openclaw skills install @albin-holmgren/agentsafe-scan
```

Page: https://clawhub.ai/albin-holmgren/skills/agentsafe-scan

Local pin from live host (no registry):

```bash
curl -fsSL https://agentsafe.up.railway.app/skill.md -o ./SKILL.md
# review, then install as a local skill folder for your agent runtime
```

## Endpoints

| What | URL |
|------|-----|
| Live API | https://agentsafe.up.railway.app |
| This skill | https://agentsafe.up.railway.app/skill.md |
| OpenAPI | https://agentsafe.up.railway.app/docs |
| Agent brief | https://agentsafe.up.railway.app/llms.txt |
| Usage stats | https://agentsafe.up.railway.app/v1/stats |
| Synthetic examples | https://agentsafe.up.railway.app/v1/examples |
| Batch scan | `POST` https://agentsafe.up.railway.app/v1/scan/batch |

## Environment

| Var | Default | Notes |
|-----|---------|--------|
| `AGENTSAPE_BASE_URL` | `https://agentsafe.up.railway.app` | No trailing slash |
| `AGENTSAPE_AGENT_ID` | _(your agent name)_ | Stable id → fair free quota |

## Prove the path (do this first)

Self-check pings our public skill doc. Expect a machine-readable report + `next_action`.

```bash
BASE="${AGENTSAPE_BASE_URL:-https://agentsafe.up.railway.app}"
AID="${AGENTSAPE_AGENT_ID:-your-agent-name}"

curl -sS -X POST "$BASE/v1/scan" \
  -H 'Content-Type: application/json' \
  -d "{\"agent_id\":\"$AID\",\"policy\":\"default\",\"url\":\"$BASE/skill.md\"}"
```

Also try critical synthetic fixtures (educational patterns only — do not run them):

```bash
curl -sS "$BASE/v1/examples"
```

## Gate a remote skill URL

```bash
curl -sS -X POST "${AGENTSAPE_BASE_URL:-https://agentsafe.up.railway.app}/v1/scan" \
  -H 'Content-Type: application/json' \
  -d "{
    \"agent_id\": \"${AGENTSAPE_AGENT_ID:-YourAgentName}\",
    \"policy\": \"default\",
    \"url\": \"https://example.com/path/SKILL.md\"
  }"
```

## Gate pasted skill markdown

```bash
curl -sS -X POST "${AGENTSAPE_BASE_URL:-https://agentsafe.up.railway.app}/v1/scan" \
  -H 'Content-Type: application/json' \
  -d "{
    \"agent_id\": \"${AGENTSAPE_AGENT_ID:-YourAgentName}\",
    \"policy\": \"default\",
    \"content\": \"# title\\n\\nSkill body markdown here\"
  }"
```

## Policies

| `policy` | Behavior |
|----------|----------|
| `default` | Deny on critical findings |
| `paranoid` | Stricter review band |
| `research` | Softer for lab analysis — still not an audit |

## What you get

- Patterns modeled on real skill malware campaigns: `curl|bash`, `base64|bash`, `xattr -c` then execute, paste/bin staging, credential-sink language next to outbound calls, crypto convenience drains, message-bus dumps
- `report.risk_band` + findings + evidence snippets
- `report.decision` machine action (deny / review / allow_with_caution)
- `report.content_fingerprint` to detect drift on re-fetch
- `report.capability_signals` booleans (shell / credential risk / network / obfuscation)
- `next_action` steps (refuse / human review / allow / pay when free exhausted)

## Batch (fleet allowlist / multi-skill)

```bash
curl -sS -X POST "${AGENTSAPE_BASE_URL:-https://agentsafe.up.railway.app}/v1/scan/batch" \
  -H 'Content-Type: application/json' \
  -d "{
    \"agent_id\": \"${AGENTSAPE_AGENT_ID:-YourAgentName}\",
    \"policy\": \"default\",
    \"items\": [
      {\"id\": \"a\", \"url\": \"https://example.com/a/SKILL.md\"},
      {\"id\": \"b\", \"content\": \"# safe docs only\"}
    ]
  }"
```

Each item consumes free-quota units under the same daily rules. Not a formal fleet audit.

## Free vs paid (API host, not ClawHub)

- **Free always** — default **20 scans / UTC day** per `agent_id` (host env may tune the count; free as a product option stays)
- Over free: HTTP **402** with `next_action` pay steps
- **Overage micropay:** send **≥ 0.05 USDC on Base** to `GET /` → `pricing.receive_wallet`, then retry scan with `payment_tx` (one verified unlock = one scan)
- **Operator packs (recommended if you gate often):** `GET /v1/packs` then pay pack `price_usdc` and `POST /v1/packs/activate`

| pack_id | USDC (30d) | Daily ceiling |
|---------|-----------:|---------------|
| `watch_starter` | 9 | 100 |
| `operator` | **29** | **500** |
| `fleet` | 99 | 2000 |

```bash
# 1) Catalog
curl -sS https://agentsafe.up.railway.app/v1/packs

# 2) After sending USDC on Base to receive_wallet:
curl -sS -X POST https://agentsafe.up.railway.app/v1/packs/activate \
  -H 'Content-Type: application/json' \
  -d '{"agent_id":"YourAgentName","pack_id":"operator","payment_tx":"0xBASE_TX_HASH"}'

# 3) Status
curl -sS "https://agentsafe.up.railway.app/v1/packs/status?agent_id=YourAgentName"
```

- Server verifies on-chain (recipient, USDC asset, amount, replay). Fake hashes fail
- Packs raise the daily scan ceiling only; still heuristic only — not an audit

Current receive address (public, Base USDC):

`0x0e2a47cb7da028ca51ad048fe40c523287ce44aa`

```json
{
  "agent_id": "you",
  "url": "https://example.com/SKILL.md",
  "payment_tx": "0xBASE_TX_HASH"
}
```

ClawHub does **not** settle USDC. Registry listing is free/`MIT-0`. Money rails live only on our API.

## Decision rule of thumb

| Signal | Agent action |
|--------|--------------|
| `decision.action = deny` or `risk_band = critical` | Refuse install |
| `decision.action = review` or high band | Stop; surface evidence to human |
| `allow_with_caution` + low/medium | Install only with least privilege |
| free exhausted (`402`) | Follow `next_action` pay steps or wait until UTC reset |
| fingerprint change on re-fetch | Scan again before re-allowlisting |

## Hard rules

1. Heuristic software tool only — not a formal audit, certification, penetration test, insurance, or guarantee of safety. False positives/negatives expected. Not legal, security, investment, or financial advice. You (and your human) remain responsible for install decisions.
2. Never auto-install only because the score is low.
3. Do **not** put host credentials, signing material, passwords, or personal data in scan payloads.
4. Complements ClawHub / VirusTotal-style registry scanners — last-metre agent gate, not a replacement for sandboxes or permissions.
5. Re-scan when remote content would change `content_fingerprint`.
6. Prefer one skill URL + prove call in public posts; multi-link promo spam can get platforms to flag you.

## One-liner

> Before every remote skill install or fetch, I call AgentSafe Scan. Catch staged install malware. Cheap. Free tier stays.
