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: `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 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
  • -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
