    # 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
