Debate Arena

• Outcome: Review
• Latest audit: Sep 12, 2026 · 8:36 AM UTC
• Version: 1.2.1

Overview

This debate skill is not overtly malicious, but it needs review because user and participant text can influence later agents that are instructed to send group messages.

Review the host integration before installing. It should restrict spawned agents to only the intended group-message capability, bind the channel/target/account outside the model prompt where possible, and avoid exposing shell, filesystem, or broad messaging tools to debaters. Treat archives and logs as retained local records, and avoid using this skill for sensitive debate topics unless retention is acceptable.

A.I.G

Vulnerability Patterns

• Skill Instruction Hijacking: Alters the agent's session goals or safety constraints when the skill loads
• Agent Memory Poisoning: Writes attacker-controlled rules into memory that affect later sessions
• Remote Payload Retrieval and Execution: Fetches external code whose behavior can change after review
• Embedded Malicious Code: Ships malicious scripts inside the skill and executes them locally
• Unauthorized Access and Privilege Escalation: Obtains permissions beyond the task's legitimate needs

Vulnerability Patterns

• Tool Misuse: Tool Parameter Abuse, Chaining Abuse, Unsafe Defaults
• Rogue Agent: Self-Modification, Session Persistence
• Prompt Injection: Instruction Override, Hidden Instructions, Exfiltration Commands
• Data Exfiltration: External Transmission, Env Variable Harvesting, File System Enumeration
• Privilege Escalation: Excessive Permissions, Sudo/Root Execution, Credential Access

Findings (8)

Tool Parameter Abuse

High

• Category: Tool Misuse
• Confidence: 85% confidence

Finding

Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).

Content

Scanner excerpt · README.md (reported line 84)May include surrounding context.

Notes:
- `default-config.json` is created only after you run `cmdConf()` / `debate conf`.
- If you want a truly clean first-run experience, delete it: `rm ~/.openclaw/debate-arena/default-config.json`.

Overrides:
- `DEBATE_ARENA_STATE_FILE`

- 若需要清理为“真·首次使用”，可删除该文件：`rm ~/.openclaw/debate-arena/default-config.json`。

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 95% confidence

Finding

The README states "README.md: English-only overview & quickstart," which is a natural-language locale restriction. Under the policy, forcing a specific language without offering user choice or documenting a justified regional constraint is a violation.

Content

No source excerpt is available for this finding.

Session Persistence

Medium

• Category: Rogue Agent
• Confidence: 60% confidence

Finding

Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.

Host recommended usage (subagent raw)

When the host receives raw JSON output from subagents, prefer the one-step wrappers that validate and write to state:

js

const debate = require('./scripts/debate-arena');

Natural-Language Policy Violations

Medium

• Category: Not specified by scanner
• Confidence: 91% confidence

Finding

The skill defines debate round tasks and many user-facing prompts entirely in Chinese, effectively forcing a specific language/locale for operation. The file does not offer any language choice or document a justified region-specific constraint, which conflicts with the language/locale policy for natural-language behavior.

Content

No source excerpt is available for this finding.

Missing User Warnings

Low

• Category: Not specified by scanner
• Confidence: 89% confidence

Finding

The skill explicitly states that debate speeches, judge comments, scores, and results are archived to local files, and that configuration can be persisted, but it does not clearly warn users that potentially sensitive conversation content will be stored on disk. In a multi-user chat setting, this can create unintended data retention and privacy exposure, especially if topics include confidential business or personal information.
