War/Den Governance Skill

ClawHub Package: an2b/warden-governance Version: 1.0.0 Category: Governance & Security License: MIT

What This Skill Does

Every action your OpenClaw bot tries to take is evaluated by War/Den before it executes.

Your Bot -> War/Den check -> ALLOW  -> action executes
                          -> DENY   -> action blocked + logged
                          -> REVIEW -> waits for your approval

No more deleted emails. No more data exfiltration. No more ungoverned agents.

Community mode works with zero external dependencies. No API keys. No cloud. Just YAML policies, a local SQLite audit log, and a hash chain you can verify.

---

Install

From ClawHub (recommended)

openclaw skill install an2b/warden-governance

From pip

pip install warden-governance-skill

Both methods install to: ~/.openclaw/skills/warden-governance/

On successful install you'll see:

🦞 War/Den governance active.
   Your OpenClaw bot is now governed.

Add to your OpenClaw config

skills:
  - name: warden-governance
    config:
      SENTINEL_API_KEY: ""       # optional -- leave blank for community mode
      ENGRAMPORT_API_KEY: ""     # optional -- leave blank for local memory
      WARDEN_FAIL_OPEN: "false"  # block on governance failure (default)

Restart your bot

openclaw restart

That's it. Your bot is now governed.

How It Works

Hooks

This skill registers three OpenClaw hooks:

Hook	Purpose
before_action	Evaluate every action against policy before execution
after_action	Write action result to governed memory
on_error	Log errors to tamper-evident audit trail

Action Bridge

All 15 OpenClaw action types are mapped to War/Den governance types:

OpenClaw Action	War/Den Type	Default Protection
email.send	message.send	Monitored
email.delete	data.write	Requires human review
email.read	data.read	Monitored
file.write	data.write	Monitored
file.delete	data.write	Requires human review
file.read	data.read	Monitored
browser.navigate	api.call	Monitored
browser.click	api.call	Monitored
shell.execute	code.execute	Blocked in production
api.call	api.call	Monitored
calendar.create	data.write	Monitored
calendar.delete	data.write	Requires human review
message.send	message.send	Monitored
code.execute	code.execute	Blocked in production
payment.create	api.call	Requires human review

Policy Engine

Policies are YAML files evaluated in priority order:

policies:
  - name: protect-email-delete
    match:
      action.type: data.write
      action.data.openclaw_original: email.delete
    decision: review
    mode: enforce
    priority: 1
    active: true
    reason: "Email deletion requires human review."

Evaluation rules:

1. Filter to active policies only
2. Sort by priority ascending (lower number = higher priority)
3. First match wins
4. mode: monitor -- log but return ALLOW
5. mode: enforce -- return the matched decision
6. No match -- default ALLOW

Pre-built Policy Packs

Load governance instantly with built-in packs:

Pack	What It Does
basic_safety	Blocks code execution in prod, monitors writes and API calls
phi_guard	Denies PHI access in dev, requires review for memory export
payments_guard	Denies payment actions in dev, requires review in prod

Audit Trail

Every governance decision is written to a tamper-evident SHA-256 hash chain:

Event N:  hash = SHA256(prev_hash + agent_id + action_type + decision + timestamp)
Event N+1: prev_hash = Event N hash

Verify the chain at any time:

valid, bad_event_id = audit_log.verify_chain()

Decision Cache

ALLOW decisions are cached for 5 minutes (configurable). DENY and REVIEW are never cached -- they always hit the governance engine fresh.

Community vs Enterprise

Feature	Community (Free)	Enterprise
Policy enforcement	Local YAML	Sentinel_OS cloud
Audit trail	Local SQLite + hash chain	Cloud + signed PDF
Memory storage	Local SQLite	EngramPort cloud (MandelDB)
Memory search	Text search (LIKE)	Vector search (3072-dim)
Synthesis	Basic recall	Eidetic AI synthesis
Cross-bot memory	--	Orchestra multi-agent
Multi-namespace	3 max	Unlimited
Compliance export	--	SOC2/HIPAA PDF
Cryptographic provenance	Local hash chain	AEGIS (SHA-256 + RSA)
Dependencies	Zero	sentinel-client, engramport-langchain

Mode Matrix

SENTINEL_API_KEY	ENGRAMPORT_API_KEY	Mode
--	--	Full Community
Set	--	Governed Community
--	Set	Memory Enterprise
Set	Set	Full Enterprise

All four modes work with zero code changes. Just environment variables.

Enterprise Upgrade Path

Sentinel_OS (Governance)

Set SENTINEL_API_KEY to upgrade governance from local YAML to Sentinel_OS cloud:

• Real-time policy evaluation via /api/v1/check
• Pre-flight checks via /api/v1/check (read-only, no side effects)
• Action logging via /api/v1/ingest with hash chain integrity
• Run management, alerting, and AI-powered insights
• Python and Node.js SDKs
• Rate limiting: 2000 checks/min, 1000 ingests/min per API key

EngramPort (Memory via MandelDB)

Set ENGRAMPORT_API_KEY to upgrade memory from local SQLite to EngramPort cloud:

• 5 endpoints: /register, /remember, /recall, /reflect, /stats
• 3072-dimensional OpenAI embeddings via Pinecone
• AEGIS cryptographic provenance (SHA-256 + RSA signature per memory)
• Namespace-isolated storage (bot:{slug}:{uid})
• Eidetic cross-memory pattern synthesis via GPT-4o-mini
• Multi-agent orchestration with EngramPortOrchestra
• Background synthesis with DreamState
• LangChain drop-in integration

API keys use format ek_bot_* with SHA-256 hashed storage.

Configuration

Variable	Required	Default	Description
SENTINEL_API_KEY	No	""	Sentinel_OS key. Blank = community governance
ENGRAMPORT_API_KEY	No	""	EngramPort key. Blank = local memory
WARDEN_FAIL_OPEN	No	false	Allow on governance failure
WARDEN_AGENT_ID	No	openclaw-agent	Bot identifier
WARDEN_POLICY_FILE	No	built-in	Path to custom YAML policy file
WARDEN_POLICY_PACKS	No	""	Comma-separated pack names
WARDEN_MEMORY_DB	No	~/.warden/memory.db	Local memory path
WARDEN_AUDIT_DB	No	~/.warden/audit.db	Local audit log path
WARDEN_CACHE_TTL	No	300	ALLOW cache TTL in seconds

Fail-Open Behavior

WARDEN_FAIL_OPEN	War/Den reachable	War/Den unreachable
false (default)	Normal governance	Action BLOCKED
true	Normal governance	Action ALLOWED + warning

Default is false because a governance failure should never silently allow dangerous actions.

---

Test Proof

This skill ships with a comprehensive test suite. Run it:

python -m pytest tests/ -v

Key test: The Meta inbox test simulates the exact incident where an OpenClaw agent deleted 200 emails. With War/Den, all 200 are blocked:

def test_meta_researcher_inbox_protection(self, tmp_path):
    """Simulate the exact Meta inbox incident. All 200 emails blocked."""
    skill = _make_skill(tmp_path, WARDEN_POLICY_FILE=policy_path)
    blocked = 0
    for i in range(200):
        result = skill.before_action(
            {"type": "email.delete", "data": {"email_id": f"msg_{i}"}},
            {"agent_id": "meta-researcher-bot", "env": "prod"},
        )
        if not result["proceed"]:
            blocked += 1
    assert blocked == 200
