# Tinman - AI Failure Mode Research

Tinman is a forward-deployed research agent that discovers unknown failure modes in AI systems through systematic experimentation.

## Security and Trust Notes

- This skill intentionally declares `install.pip` and session/file permissions because scanning requires local analysis of session traces and report output.
- The default watch gateway is loopback-only (`ws://127.0.0.1:18789`) to reduce accidental data exposure.
- Remote gateways require explicit opt-in with `--allow-remote-gateway` and should only be used for trusted internal endpoints.
- Event streaming is local (`~/.openclaw/workspace/tinman-events.jsonl`) and best-effort; values are truncated and obvious secret patterns are redacted.

## What It Does

- **Checks** tool calls before execution for security risks (agent self-protection)
- **Scans** recent sessions for prompt injection, tool misuse, context bleed
- **Classifies** failures by severity (S0-S4) and type
- **Proposes** mitigations mapped to OpenClaw controls (SOUL.md, sandbox policy, tool allow/deny)
- **Reports** findings in actionable format
- **Streams** structured local events to `~/.openclaw/workspace/tinman-events.jsonl` (for local dashboards like Oilcan)

## Commands

### `/tinman init`

Initialize Tinman workspace with default configuration.

```
/tinman init                    # Creates ~/.openclaw/workspace/tinman.yaml
```

Run this first time to set up the workspace.

### `/tinman check` (Agent Self-Protection)

Check if a tool call is safe before execution. **This enables agents to self-police.**

```
/tinman check bash "cat ~/.ssh/id_rsa"    # Returns: BLOCKED (S4)
/tinman check bash "ls -la"               # Returns: SAFE
/tinman check bash "curl https://api.com" # Returns: REVIEW (S2)
/tinman check read ".env"                 # Returns: BLOCKED (S4)
```

**Verdicts:**
- `SAFE` - Proceed automatically
- `REVIEW` - Ask human for approval (in `safer` mode)
- `BLOCKED` - Refuse the action

**Add to SOUL.md for autonomous protection:**
```markdown
Before executing bash, read, or write tools, run:
  /tinman check <tool> <args>
If BLOCKED: refuse and explain why
If REVIEW: ask user for approval
If SAFE: proceed
```

### `/tinman mode`

Set or view security mode for the check system.

```
/tinman mode                    # Show current mode
/tinman mode safer              # Default: ask human for REVIEW, block BLOCKED
/tinman mode risky              # Auto-approve REVIEW, still block S3-S4
/tinman mode yolo               # Warn only, never block (testing/research)
```

| Mode | SAFE | REVIEW (S1-S2) | BLOCKED (S3-S4) |
|------|------|----------------|-----------------|
| `safer` | Proceed | Ask human | Block |
| `risky` | Proceed | Auto-approve | Block |
| `yolo` | Proceed | Auto-approve | Warn only |

### `/tinman allow`

Add patterns to the allowlist (bypass security checks for trusted items).

```
/tinman allow api.trusted.com --type domains    # Allow specific domain
/tinman allow "npm install" --type patterns     # Allow pattern
/tinman allow curl --type tools                 # Allow tool entirely
```

### `/tinman allowlist`

Manage the allowlist.

```
/tinman allowlist --show        # View current allowlist
/tinman allowlist --clear       # Clear all allowlisted items
```

### `/tinman scan`

Analyze recent sessions for failure modes.

```
/tinman scan                    # Last 24 hours, all failure types
/tinman scan --hours 48         # Last 48 hours
/tinman scan --focus prompt_injection
/tinman scan --focus tool_use
/tinman scan --focus context_bleed
```

**Output:** Writes findings to `~/.openclaw/workspace/tinman-findings.md`

### `/tinman report`

Display the latest findings report.

```
/tinman report                  # Summary view
/tinman report --full           # Detailed with evidence
```

### `/tinman watch`

Continuous monitoring mode with two options:

**Real-time mode (recommended):** Connects to Gateway WebSocket for instant event monitoring.
```
/tinman watch                           # Real-time via ws://127.0.0.1:18789
/tinman watch --gateway ws://host:port  # Custom gateway URL
/tinman watch --gateway ws://host:port --allow-remote-gateway  # Explicit opt-in for remote
/tinman watch --interval 5              # Analysis every 5 minutes
```

**Polling mode:** Periodic session scans (fallback when gateway unavailable).
```
/tinman watch --mode polling            # Hourly scans
/tinman watch --mode polling --interval 30  # Every 30 minutes
```

**Stop watching:**
```
/tinman watch --stop                    # Stop background watch process
```

**Heartbeat Integration:** For scheduled scans, configure in heartbeat:
```yaml
# In gateway heartbeat config
heartbeat:
  jobs:
    - name: tinman-security-scan
      schedule: "0 * * * *"  # Every hour
      command: /tinman scan --hours 1
```

### `/tinman sweep`

Run proactive security sweep with 288 synthetic attack probes.

```
/tinman sweep                              # Full sweep, S2+ severity
/tinman sweep --severity S3                # High severity only
/tinman sweep --category prompt_injection  # Jailbreaks, DAN, etc.
/tinman sweep --category tool_exfil        # SSH keys, credentials
/tinman sweep --category context_bleed     # Cross-session leaks
/tinman sweep --category privilege_escalation
```

**Attack Categories:**
- `prompt_injection` (15): Jailbreaks, instruction override
- `tool_exfil` (42): SSH keys, credentials, cloud creds, network exfil
- `context_bleed` (14): Cross-session leaks, memory extraction
- `privilege_escalation` (15): Sandbox escape, elevation bypass
- `supply_chain` (18): Malicious skills, dependency/update attacks
- `financial_transaction` (26): Wallet/seed theft, transactions, exchange API keys (alias: `financial`)
- `unauthorized_action` (28): Actions without consent, implicit execution
- `mcp_attack` (20): MCP tool abuse, server injection, cross-tool exfil (alias: `mcp_attacks`)
- `indirect_injection` (20): Injection via files, URLs, documents, issues
- `evasion_bypass` (30): Unicode/encoding bypass, obfuscation
- `memory_poisoning` (25): Persistent instruction poisoning, fabricated history
- `platform_specific` (35): Windows/macOS/Linux/cloud-metadata payloads

**Output:** Writes sweep report to `~/.openclaw/workspace/tinman-sweep.md`

## Failure Categories

| Category | Description | OpenClaw Control |
|----------|-------------|------------------|
| `prompt_injection` | Jailbreaks, instruction override | SOUL.md guardrails |
| `tool_use` | Unauthorized tool access, exfil attempts | Sandbox denylist |
| `context_bleed` | Cross-session data leakage | Session isolation |
| `reasoning` | Logic errors, hallucinated actions | Model selection |
| `feedback_loop` | Group chat amplification | Activation mode |

## Severity Levels

- **S0**: Observation only, no action needed
- **S1**: Low risk, monitor
- **S2**: Medium risk, review recommended
- **S3**: High risk, mitigation recommended
- **S4**: Critical, immediate action required
