Tinman - AI Failure Mode Research, Prompt Injection & Tool Exfil Detection

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

/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 <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) ModeSAFEREVIEW (S1-S2)BLOCKED (S3-S4)saferProceedAsk humanBlockriskyProceedAuto-approveBlockyoloProceedAuto-approveWarn 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 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

Configuration

Create ~/.openclaw/workspace/tinman.yaml to customize: # Tinman configuration mode: shadow # shadow (observe) or lab (with synthetic probes) focus: - prompt_injection - tool_use - context_bleed severity_threshold: S2 # Only report S2 and above auto_watch: false # Auto-start watch mode report_channel: null # Optional: send alerts to channel
