- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Then review README.md for any prerequisites, environment setup, or post-install checks. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Then review README.md for any prerequisites, environment setup, or post-install checks. Summarize what changed and any follow-up checks I should run.
```

## Documentation

### Claw Permission Firewall

Runtime least-privilege firewall for agent/skill actions. It evaluates a requested action and returns one of:

ALLOW (safe to execute)
DENY (blocked by policy)
NEED_CONFIRMATION (risky; require explicit confirmation)

It also returns a sanitizedAction with secrets redacted, plus a structured audit record.

This is not a gateway hardening tool. It complements gateway security scanners by enforcing per-action policy at runtime.

### What it protects against

Exfiltration to unknown domains
Prompt-injection “send secrets” attempts (secret detection + redaction)
Reading sensitive local files (~/.ssh, ~/.aws, .env, etc.)
Unsafe execution patterns (rm -rf, curl | sh, etc.)

### Inputs

Provide an action object to evaluate:

{
  "traceId": "optional-uuid",
  "caller": { "skillName": "SomeSkill", "skillVersion": "1.2.0" },
  "action": {
    "type": "http_request | file_read | file_write | exec",
    "method": "GET|POST|PUT|DELETE",
    "url": "https://api.github.com/...",
    "headers": { "authorization": "Bearer ..." },
    "body": "...",
    "path": "./reports/out.json",
    "command": "rm -rf /"
  },
  "context": {
    "workspaceRoot": "/workspace",
    "mode": "strict | balanced | permissive",
    "confirmed": false
  }
}

### Outputs

{
  "decision": "ALLOW | DENY | NEED_CONFIRMATION",
  "riskScore": 0.42,
  "reasons": [{"ruleId":"...","message":"..."}],
  "sanitizedAction": { "...": "..." },
  "confirmation": { "required": true, "prompt": "..." },
  "audit": { "traceId":"...", "policyVersion":"...", "actionFingerprint":"..." }
}

### Default policy behavior (v1)

Exec disabled by default
HTTP requires TLS
Denylist blocks common exfil hosts (pastebins, raw script hosts)
File access is jailed to workspaceRoot
Always redacts Authorization, Cookie, X-API-Key, and common token patterns

### Recommended usage pattern

Your skill creates an action object.
Call this skill to evaluate it.
If ALLOW → execute sanitizedAction.
If NEED_CONFIRMATION → ask user and re-run with context.confirmed=true.
If DENY → stop and show the reasons.

### Files

policy.yaml contains the policy (edit for your environment).
