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.pipand 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-gatewayand 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
