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.
  • Oilcan bridge should stay loopback by default; only allow LAN access when explicitly needed.
  • 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)
  • Guides local Oilcan setup with plain-language status via /tinman 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:

    Before executing bash, read, or write tools, run:
      /tinman check  
    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:

    # In gateway heartbeat config
    heartbeat:
      jobs:
        - name: tinman-security-scan
          schedule: "0 * * * *"  # Every hour
          command: /tinman scan --hours 1
    

    /tinman oilcan

    Show local Oilcan setup/status in plain language.

    /tinman oilcan                    # Human-readable status + setup steps
    /tinman oilcan --json             # Machine-readable status payload
    /tinman oilcan --bridge-port 18128
    

    This command helps users connect Tinman event output to Oilcan and reminds them that the bridge may auto-select a different port if the preferred one is already in use.

    /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

  • 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
